2022-04-22tty: n_gsm: fix invalid use of MSC in advanced optionDaniel Starke
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010. See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516 The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to the newer 27.010 here. Chapter 5.4.6.3.7 states that the Modem Status Command (MSC) shall only be used if the basic option was chosen. The current implementation uses MSC frames even if advanced option was chosen to inform the peer about modem line state updates. A standard conform peer may choose to discard these frames in advanced option mode. Furthermore, gsmtty_modem_update() is not part of the 'tty_operations' functions despite its name. Rename gsmtty_modem_update() to gsm_modem_update() to clarify this. Split its function into gsm_modem_upd_via_data() and gsm_modem_upd_via_msc() depending on the encoding and adaption. Introduce gsm_dlci_modem_output() as adaption of gsm_dlci_data_output() to encode and queue empty frames in advanced option mode. Use it in gsm_modem_upd_via_data(). gsm_modem_upd_via_msc() is based on the initial gsmtty_modem_update() function which used only MSC frames to update modem states.

2022-04-22tty: n_gsm: fix broken virtual tty handlingDaniel Starke
Dynamic virtual tty registration was introduced to allow the user to handle these cases with uevent rules. The following commits relate to this: Commit 5b87686e3203 ("tty: n_gsm: Modify gsmtty driver register method when config requester") Commit 0b91b5332368 ("tty: n_gsm: Save dlci address open status when config requester") Commit 46292622ad73 ("tty: n_gsm: clean up indenting in gsm_queue()") However, the following behavior can be seen with this implementation: - n_gsm ldisc is activated via ioctl - all configuration parameters are set to their default value (initiator=0) - the mux gets activated and attached and gsmtty0 is being registered in in gsm_dlci_open() after DLCI 0 was established (DLCI 0 is the control channel) - the user configures n_gsm via ioctl GSMIOC_SETCONF as initiator - this re-attaches the n_gsm mux - no new gsmtty devices are registered in gsmld_attach_gsm() because the mux is already active - the initiator side registered only the control channel as gsmtty0 (which should never happen) and no user channel tty The commits above make it impossible to operate the initiator side as no user channel tty is or will be available. On the other hand, this behavior will make it also impossible to allow DLCI parameter negotiation on responder side in the future. The responder side first needs to provide a device for the application before the application can set its parameters of the associated DLCI via ioctl. Note that the user application is still able to detect a link establishment without relaying to uevent by waiting for DTR open on responder side. This is the same behavior as on a physical serial interface. And on initiator side a tty hangup can be detected if a link establishment request failed. Revert the commits above completely to always register all user channels and no control channel after mux attachment. No other changes are made.

2022-04-22Revert "serial: sc16is7xx: Clear RS485 bits in the shutdown"Hui Wang
This reverts commit 927728a34f11b5a27f4610bdb7068317d6fdc72a. Once the uart_port->rs485->flag is set to SER_RS485_ENABLED, the port should always work in RS485 mode. If users want the port to leave RS485 mode, they need to call ioctl() to clear SER_RS485_ENABLED. So here we shouldn't clear the RS485 bits in the shutdown().

2022-04-22iommu: arm-smmu: disable large page mappings for Nvidia arm-smmuAshish Mhetre
Tegra194 and Tegra234 SoCs have the erratum that causes walk cache entries to not be invalidated correctly. The problem is that the walk cache index generated for IOVA is not same across translation and invalidation requests. This is leading to page faults when PMD entry is released during unmap and populated with new PTE table during subsequent map request. Disabling large page mappings avoids the release of PMD entry and avoid translations seeing stale PMD entry in walk cache. Fix this by limiting the page mappings to PAGE_SIZE for Tegra194 and Tegra234 devices. This is recommended fix from Tegra hardware design team.

2022-04-21clk: qcom: clk-rcg2: fix gfx3d frequency calculationDmitry Baryshkov
Since the commit 948fb0969eae ("clk: Always clamp the rounded rate"), the clk_core_determine_round_nolock() would clamp the requested rate between min and max rates from the rate request. Normally these fields would be filled by clk_core_get_boundaries() called from clk_round_rate(). However clk_gfx3d_determine_rate() uses a manually crafted rate request, which did not have these fields filled. Thus the requested frequency would be clamped to 0, resulting in weird frequencies being requested from the hardware. Fix this by filling min_rate and max_rate to the values valid for the respective PLLs (0 and ULONG_MAX).

2022-04-21ACPI: processor: idle: Avoid falling back to C3 type C-statesVille Syrjälä
The "safe state" index is used by acpi_idle_enter_bm() to avoid entering a C-state that may require bus mastering to be disabled on entry in the cases when this is not going to happen. For this reason, it should not be set to point to C3 type of C-states, because they may require bus mastering to be disabled on entry in principle. This was broken by commit d6b88ce2eb9d ("ACPI: processor idle: Allow playing dead in C3 state") which inadvertently allowed the "safe state" index to point to C3 type of C-states. This results in a machine that won't boot past the point when it first enters C3. Restore the correct behaviour (either demote to C1/C2, or use C3 but also set ARB_DIS=1). I hit this on a Fujitsu Siemens Lifebook S6010 (P3) machine.

2022-04-21usb: core: Don't hold the device lock while sleeping in do_proc_control()Tasos Sahanidis
Since commit ae8709b296d8 ("USB: core: Make do_proc_control() and do_proc_bulk() killable") if a device has the USB_QUIRK_DELAY_CTRL_MSG quirk set, it will temporarily block all other URBs (e.g. interrupts) while sleeping due to a control. This results in noticeable delays when, for example, a userspace usbfs application is sending URB interrupts at a high rate to a keyboard and simultaneously updates the lock indicators using controls. Interrupts with direction set to IN are also affected by this, meaning that delivery of HID reports (containing scancodes) to the usbfs application is delayed as well. This patch fixes the regression by calling msleep() while the device mutex is unlocked, as was the case originally with usb_control_msg().

2022-04-21usb: dwc3: Try usb-role-switch first in dwc3_drd_initSven Peter
If the PHY controller node has a "port" dwc3 tries to find an extcon device even when "usb-role-switch" is present. This happens because dwc3_get_extcon() sees that "port" node and then calls extcon_find_edev_by_node() which will always return EPROBE_DEFER in that case. On the other hand, even if an extcon was present and dwc3_get_extcon() was successful it would still be ignored in favor of "usb-role-switch". Let's just first check if "usb-role-switch" is configured in the device tree and directly use it instead and only try to look for an extcon device otherwise.

Issue description: When an OTG port has been switched to device role and then switch back to host role again, the USB 3.0 Host (XHCI) will not be able to detect "plug in event of a connected USB 2.0/1.0 ((Highspeed and Fullspeed) devices until system reboot. Root cause and Solution: There is a condition checking flag "ssusb->otg_switch.is_u3_drd" in toggle_opstate(). At the end of role switch procedure, toggle_opstate() will be called to set DC_SESSION and SOFT_CONN bit.

2022-04-21usb: dwc3: fix backwards compat with rockchip devicesPeter Geis
Commit 33fb697ec7e5 ("usb: dwc3: Get clocks individually") moved from the clk_bulk api to individual clocks, following the snps,dwc3.yaml dt-binding for clock names. Unfortunately the rk3328 (and upcoming rk356x support) use the rockchip,dwc3.yaml which has different clock names, which are common on devices using the glue layer. The rk3328 does not use a glue layer, but attaches directly to the dwc3 core driver. The offending patch series failed to account for this, thus dwc3 was broken on rk3328. To retain backwards compatibility with rk3328 device trees we must also check for the alternate clock names.

2022-04-21USB: Fix ehci infinite suspend-resume loop issue in zhaoxinWeitao Wango
In zhaoxin platform, some ehci projects will latch a wakeup signal internal when plug in a device on port during system S0. This wakeup signal will turn on when ehci runtime suspend, which will trigger a system control interrupt that will resume ehci back to D0. As no device connect, ehci will be set to runtime suspend and turn on the internal latched wakeup signal again. It will cause a suspend-resume loop and generate system control interrupt continuously. Fixed this issue by clear wakeup signal latched in ehci internal when ehci resume callback is called.

2022-04-21memory: renesas-rpc-if: Fix HF/OSPI data transfer in Manual ModeGeert Uytterhoeven
HyperFlash devices fail to probe: rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits (SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived from half of the transfer size, cfr. the rpcif_bits_set() helper function. However, rpcif_reg_{read,write}() does not take the bus size into account, and does not double all Manual Mode Data Register access sizes when communicating with a HyperFlash or Octal-SPI Flash device. Fix this, and avoid the back-and-forth conversion between transfer size and Transfer Data Enable bits, by explicitly storing the transfer size in struct rpcif, and using that value to determine access size in rpcif_reg_{read,write}(). Enforce that the "high" Manual Mode Read/Write Data Registers (SM[RW]DR1) are only used for 8-byte data accesses. While at it, forbid writing to the Manual Mode Read Data Registers, as they are read-only.

Commit '80253168dbfd ("drm: of: Lookup if child node has panel or bridge")' attempted to simplify the case of expressing a simple panel under a DSI controller, by assuming that the first non-graph child node was a panel or bridge. Unfortunately for non-trivial cases the first child node might not be a panel or bridge. Examples of this can be a aux-bus in the case of DisplayPort, or an opp-table represented before the panel node. In these cases the reverted commit prevents the caller from ever finding a reference to the panel. This reverts commit '80253168dbfd ("drm: of: Lookup if child node has panel or bridge")', in favor of using an explicit graph reference to the panel in the trivial case as well.

2022-04-21Revert "drm: of: Properly try all possible cases for bridge/panel detection"Bjorn Andersson
Commit '80253168dbfd ("drm: of: Lookup if child node has panel or bridge")' introduced the ability to describe a panel under a display controller without having to use a graph to connect the controller to its single child panel (or bridge). The implementation of this would find the first non-graph node and attempt to acquire the related panel or bridge. This prevents cases where any other child node, such as a aux bus for a DisplayPort controller, or an opp-table to find the referenced panel. Commit '67bae5f28c89 ("drm: of: Properly try all possible cases for bridge/panel detection")' attempted to solve this problem by not bypassing the graph reference lookup before attempting to find the panel or bridge. While this does solve the case where a proper graph reference is present, it does not allow the caller to distinguish between a yet-to-be-probed panel or bridge and the absence of a reference to a panel. One such case is a DisplayPort controller that on some boards have an explicitly described reference to a panel, but on others have a discoverable DisplayPort display attached (which doesn't need to be expressed in DeviceTree). This reverts commit '67bae5f28c89 ("drm: of: Properly try all possible cases for bridge/panel detection")', as a step towards reverting commit '80253168dbfd ("drm: of: Lookup if child node has panel or bridge")'.

2022-04-20drm/vmwgfx: Fix gem refcounting and memory evictionsZack Rusin
v2: Add the last part of the ref count fix which was spotted by Philipp Sieweck where the ref count of cpu writers is off due to ERESTARTSYS or EBUSY during bo waits. The initial GEM port broke refcounting on shareable (prime) surfaces and memory evictions. The prime surfaces broke because the parent surfaces weren't increasing the ref count on GEM surfaces, which meant that the memory backing textures could have been deleted while the texture was still accessible. The evictions broke due to a typo, the code was supposed to exit if the passed buffers were not vmw_buffer_object not if they were. They're tied because the evictions depend on having memory to actually evict. This fixes crashes with XA state tracker which is used for xrender acceleration on xf86-video-vmware, apps/tests which use a lot of memory (a good test being the piglit's streaming-texture-leak) and desktops.

kmap() is being deprecated and these usages are all local to the thread so there is no reason kmap_local_page() can't be used. Replace kmap() calls with kmap_local_page().

2022-04-20arch_topology: Do not set llc_sibling if llc_id is invalidWang Qing
When ACPI is not enabled, cpuid_topo->llc_id = cpu_topo->llc_id = -1, which will set llc_sibling 0xff(...), this is misleading. Don't set llc_sibling(default 0) if we don't know the cache topology.
