2023-03-25drm: rcar-du: Fix a NULL vs IS_ERR() bugDan Carpenter
The drmm_encoder_alloc() function returns error pointers. It never returns NULL. Fix the check accordingly.

2023-03-25drm: rcar-du: Write correct values in DORCR reserved fieldsLaurent Pinchart
The DORCR register controls the routing of clocks and data between DU channels within a group. For groups that contain a single channel, there's no routing option to control, and some fields of the register are then reserved. On Gen2 those reserved fields are documented as required to be set to 0, while on Gen3 and newer the PG1T, DK1S and PG1D reserved fields must be set to 1. The DU driver initializes the DORCR register in rcar_du_group_setup(), where it ignores the PG1T, DK1S and PG1D, and then configures those fields to the correct value in rcar_du_group_set_routing(). This hasn't been shown to cause any issue, but prevents certifying that the driver complies with the documentation in safety-critical use cases. As there is no reasonable change that the documentation will be updated to clarify that those reserved fields can be written to 0 temporarily before starting the hardware, make sure that the registers are always set to valid values.

2023-03-25drm: rcar-du: Rename DORCR fields to make them 0-basedLaurent Pinchart
The DORCR fields were documented in the R-Car H1 datasheet with 1-based named, and then got renamed to 0-based in Gen2. The 0-based names are used for Gen3 and Gen4, making H1 an outlier. Rename the field macros to make them 0-based, in order to increase readability of the code when comparing it with the documentation.

2023-03-25drm: rcar-du: Don't write unimplemented ESCR and OTAR registers on Gen3Laurent Pinchart
The ESCR and OTAR registers are not present in all DU channels on Gen3 SoCs. ESCR only exists in channels that can be routed to an LVDS or DPAD, and OTAR in channels that can be routed to a DPAD. Skip writing those registers for other channels. This replaces the DU gen check, as Gen4 doesn't have LVDS or DPAD outputs.

2023-03-25drm: rcar-du: lvds: Fix LVDS PLL disable on D3/E3Laurent Pinchart
On R-Car D3 and E3, the LVDS encoder provides the dot (pixel) clock to the DU, regardless of whether the LVDS output is used or not. When using the DPAD (RGB) output, the DU driver thus enables and disables the LVDS PLL manually, while when using the LVDS output, it lets the LVDS bridge driver handle the PLL configuration internally as part of the atomic enable and disable operations. This causes an issue when using the LVDS output. As bridges are disabled before CRTCs, the current implementation violates the enable/disable sequences documented in the hardware datasheet, which requires the dot clock to be enabled before the CRTC is started and disabled after it gets stopped. Fix the problem by enabling/disabling the LVDS PLL manually from the DU regardless of which output is used, and skipping the PLL handling in the LVDS bridge atomic enable and disable operations. This is however not enough. Disabling the LVDS encoder while leaving the PLL on still results in a vertical blanking wait timeout when disabling the DU. Investigation showed that the culprit is the LVEN bit. For an unclear reason, clearing the bit when disabling the LVDS encoder blocks vertical blanking interrupts. We thus have to delay disabling the whole LVDS encoder, not just disabling the PLL, until the DU is disabled. We could split the LVDS disable sequence by clearing the LVRES bit in the LVDS bridge atomic disable handler, and delaying the rest of the operations, in order to disable the LVDS output at bridge atomic disable time, before stopping the CRTC. This would make the code more complex, without a clear benefit, so keep the implementation simple(r).

2023-03-25drm: rcar-du: lvds: Move LVDS enable code to separate code sectionLaurent Pinchart
To prepare for a rework of the LVDS disable code, which will need to be called from rcar_lvds_pclk_disable(), move the LVDS enable code, currently stored in the __rcar_lvds_atomic_enable() function, to a separate code section separate from bridge operations. It will be then extended with the LVDS disable code. As part of this rework the __rcar_lvds_atomic_enable() function is renamed to rcar_lvds_enable() to more clearly indicate its purpose. No functional change intended.

Add a way to hint to the fence signaler of an upcoming deadline, such as vblank, which the fence waiter would prefer not to miss. This is to aid the fence signaler in making power management decisions, like boosting frequency as the deadline approaches and awareness of missing deadlines so that can be factored in to the frequency scaling. v2: Drop dma_fence::deadline and related logic to filter duplicate deadlines, to avoid increasing dma_fence size. The fence-context implementation will need similar logic to track deadlines of all the fences on the same timeline.

2023-03-23Bluetooth: btqcomsmd: Fix command timeout after setting BD addressStephan Gerhold
On most devices using the btqcomsmd driver (e.g. the DragonBoard 410c and other devices based on the Qualcomm MSM8916/MSM8909/... SoCs) the Bluetooth firmware seems to become unresponsive for a while after setting the BD address. On recent kernel versions (at least 5.17+) this often causes timeouts for subsequent commands, e.g. the HCI reset sent by the Bluetooth core during initialization: Bluetooth: hci0: Opcode 0x c03 failed: -110 Unfortunately this behavior does not seem to be documented anywhere. Experimentation suggests that the minimum necessary delay to avoid the problem is ~150us. However, to be sure add a sleep for > 1ms in case it is a bit longer on other firmware versions. Older kernel versions are likely also affected, although perhaps with slightly different errors or less probability. Side effects can easily hide the issue in most cases, e.g. unrelated incoming interrupts that cause the necessary delay.

2023-03-23usb: dwc2: fix a race, don't power off/on phy for dual-role modeFabrice Gasnier
When in dual role mode (dr_mode == USB_DR_MODE_OTG), platform probe successively basically calls: - dwc2_gadget_init() - dwc2_hcd_init() - dwc2_lowlevel_hw_disable() since recent change [1] - usb_add_gadget_udc() The PHYs (and so the clocks it may provide) shouldn't be disabled for all SoCs, in OTG mode, as the HCD part has been initialized. On STM32 this creates some weird race condition upon boot, when: - initially attached as a device, to a HOST - and there is a gadget script invoked to setup the device part. Below issue becomes systematic, as long as the gadget script isn't started by userland: the hardware PHYs (and so the clocks provided by the PHYs) remains disabled. It ends up in having an endless interrupt storm, before the watchdog resets the platform. [ 16.924163] dwc2 49000000.usb-otg: EPs: 9, dedicated fifos, 952 entries in SPRAM [ 16.962704] dwc2 49000000.usb-otg: DWC OTG Controller [ 16.966488] dwc2 49000000.usb-otg: new USB bus registered, assigned bus number 2 [ 16.974051] dwc2 49000000.usb-otg: irq 77, io mem 0x49000000 [ 17.032170] hub 2-0:1.0: USB hub found [ 17.042299] hub 2-0:1.0: 1 port detected [ 17.175408] dwc2 49000000.usb-otg: Mode Mismatch Interrupt: currently in Host mode [ 17.181741] dwc2 49000000.usb-otg: Mode Mismatch Interrupt: currently in Host mode [ 17.189303] dwc2 49000000.usb-otg: Mode Mismatch Interrupt: currently in Host mode ... The host part is also not functional, until the gadget part is configured. The HW may only be disabled for peripheral mode (original init), e.g. dr_mode == USB_DR_MODE_PERIPHERAL, until the gadget driver initializes. But when in USB_DR_MODE_OTG, the HW should remain enabled, as the HCD part is able to run, while the gadget part isn't necessarily configured. I don't fully get the of purpose the original change, that claims disabling the hardware is missing. It creates conditions on SOCs using the PHY initialization to be completely non working in OTG mode. Original change [1] should be reworked to be platform specific.

2023-03-23usb: dwc2: fix a devres leak in hw_enable upon suspend resumeFabrice Gasnier
Each time the platform goes to low power, PM suspend / resume routines call: __dwc2_lowlevel_hw_enable -> devm_add_action_or_reset(). This adds a new devres each time. This may also happen at runtime, as dwc2_lowlevel_hw_enable() can be called from udc_start(). This can be seen with tracing: - echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable - go to low power - cat /sys/kernel/debug/tracing/trace A new "ADD" entry is found upon each low power cycle: ... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes) ... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes) ... A second issue is addressed here: - regulator_bulk_enable() is called upon each PM cycle (suspend/resume). - regulator_bulk_disable() never gets called. So the reference count for these regulators constantly increase, by one upon each low power cycle, due to missing regulator_bulk_disable() call in __dwc2_lowlevel_hw_disable(). The original fix that introduced the devm_add_action_or_reset() call, fixed an issue during probe, that happens due to other errors in dwc2_driver_probe() -> dwc2_core_reset(). Then the probe fails without disabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL. Rather fix the error path: disable all the low level hardware in the error path, by using the "hsotg->ll_hw_enabled" flag. Checking dr_mode has been introduced to avoid a dual call to dwc2_lowlevel_hw_disable(). "ll_hw_enabled" should achieve the same (and is used currently in the remove() routine).
