2020-03-19net: phy: mscc: RGMII skew delay configurationAntoine Tenart
This patch adds support for configuring the RGMII skew delays in Rx and Tx. The Rx and Tx skews are set based on the interface mode. By default their configuration is set to the default value in hardware (0.2ns); this means the driver do not rely anymore on the bootloader configuration. Then based on the interface mode being used, a 2ns delay is added: - RGMII_ID adds it for both Rx and Tx. - RGMII_RXID adds it for Rx. - RGMII_TXID adds it for Tx.

2020-03-19net: dsa: mt7530: Change the LINK bit to reflect the link statusRené van Dorst
Andrew reported: After a number of network port link up/down changes, sometimes the switch port gets stuck in a state where it thinks it is still transmitting packets but the cpu port is not actually transmitting anymore. In this state you will see a message on the console "mtk_soc_eth 1e100000.ethernet eth0: transmit timed out" and the Tx counter in ifconfig will be incrementing on virtual port, but not incrementing on cpu port. The issue is that MAC TX/RX status has no impact on the link status or queue manager of the switch. So the queue manager just queues up packets of a disabled port and sends out pause frames when the queue is full. Change the LINK bit to reflect the link status.

2020-03-19net: phy: mscc: add missing check on a phy_write return valueAntoine Tenart
Commit a5afc1678044 ("net: phy: mscc: add support for VSC8584 PHY") introduced a call to 'phy_write' storing its return value to a variable called 'ret'. But 'ret' never was checked for a possible error being returned, and hence was not used at all. Fix this by checking the return value and exiting the function if an error was returned. As this does not fix a known bug, this commit is mostly cosmetic and not sent as a fix. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-03-19mlxsw: pci: Only issue reset when system is readyIdo Schimmel
During initialization the driver issues a software reset command and then waits for the system status to change back to "ready" state. However, before issuing the reset command the driver does not check that the system is actually in "ready" state. On Spectrum-{1,2} systems this was always the case as the hardware initialization time is very short. On Spectrum-3 systems this is no longer the case. This results in the software reset command timing-out and the driver failing to load: [ 6.347591] mlxsw_spectrum3 0000:06:00.0: Cmd exec timed-out (opcode=40(ACCESS_REG),opcode_mod=0,in_mod=0) [ 6.358382] mlxsw_spectrum3 0000:06:00.0: Reg cmd access failed (reg_id=9023(mrsr),type=write) [ 6.368028] mlxsw_spectrum3 0000:06:00.0: cannot register bus device [ 6.375274] mlxsw_spectrum3: probe of 0000:06:00.0 failed with error -110 Fix this by waiting for the system to become ready both before issuing the reset command and afterwards.

2020-03-19rsxx: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertenly introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle. [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://github.com/KSPP/linux/issues/21 [3] commit 76497732932f ("cxgb3/l2t: Fix undefined behaviour") Signed-off-by: Gustavo A. R.

2020-03-19drm/amd/display: Fix pageflip event race condition for DCN.Mario Kleiner
Commit '16f17eda8bad ("drm/amd/display: Send vblank and user events at vsartup for DCN")' introduces a new way of pageflip completion handling for DCN, and some trouble. The current implementation introduces a race condition, which can cause pageflip completion events to be sent out one vblank too early, thereby confusing userspace and causing flicker: prepare_flip_isr(): 1. Pageflip programming takes the ddev->event_lock. 2. Sets acrtc->pflip_status == AMDGPU_FLIP_SUBMITTED 3. Releases ddev->event_lock. --> Deadline for surface address regs double-buffering passes on target pipe. 4. dc_commit_updates_for_stream() MMIO programs the new pageflip into hw, but too late for current vblank. => pflip_status == AMDGPU_FLIP_SUBMITTED, but flip won't complete in current vblank due to missing the double-buffering deadline by a tiny bit. 5. VSTARTUP trigger point in vblank is reached, VSTARTUP irq fires, dm_dcn_crtc_high_irq() gets called. 6. Detects pflip_status == AMDGPU_FLIP_SUBMITTED and assumes the pageflip has been completed/will complete in this vblank and sends out pageflip completion event to userspace and resets pflip_status = AMDGPU_FLIP_NONE. => Flip completion event sent out one vblank too early. This behaviour has been observed during my testing with measurement hardware a couple of time. The commit message says that the extra flip event code was added to dm_dcn_crtc_high_irq() to prevent missing to send out pageflip events in case the pflip irq doesn't fire, because the "DCH HUBP" component is clock gated and doesn't fire pflip irqs in that state. Also that this clock gating may happen if no planes are active. This suggests that the problem addressed by that commit can't happen if planes are active. The proposed solution is therefore to only execute the extra pflip completion code iff the count of active planes is zero and otherwise leave pflip completion handling to the pflip irq handler, for a more race-free experience. Note that i don't know if this fixes the problem the original commit tried to address, as i don't know what the test scenario was. It does fix the observed too early pageflip events though and points out the problem introduced.

I have hit the following build error: armv7a-hardfloat-linux-gnueabi-ld: drivers/phy/tegra/xusb.o: in function `tegra_xusb_port_unregister': xusb.c:(.text+0x2ac): undefined reference to `usb_remove_phy' armv7a-hardfloat-linux-gnueabi-ld: drivers/phy/tegra/xusb.o: in function `tegra_xusb_setup_ports': xusb.c:(.text+0xf30): undefined reference to `usb_add_phy_dev' PHY_TEGRA_XUSB should select USB_PHY because it uses symbols defined in the code enabled by that.
