2021-07-27net: hns3: change the method of obtaining default ptp cycleYufeng Mo
The ptp cycle is related to the hardware, so it may cause compatibility issues if a fixed value is used in driver. Therefore, the method of obtaining this value is changed to read from the register rather than use a fixed value in driver.

2021-07-27drm/amdgpu/display: only enable aux backlight control for OLED panelsAlex Deucher
We've gotten a number of reports about backlight control not working on panels which indicate that they use aux backlight control. A recent patch: commit 2d73eabe2984a435737498ab39bb1500a9ffe9a9 Author: Camille Cho <Camille.Cho@amd.com> Date: Thu Jul 8 18:28:37 2021 +0800 drm/amd/display: Only set default brightness for OLED [Why] We used to unconditionally set backlight path as AUX for panels capable of backlight adjustment via DPCD in set default brightness. [How] This should be limited to OLED panel only since we control backlight via PWM path for SDR mode in LCD HDR panel.

It turns out that when the display is enabled by the bootloader, we can get some transient iommu faults from the display. Which doesn't go over too well when we install a fault handler that is gpu specific. To avoid this, defer installing the fault handler until we get around to setting up per-process pgtables (which is adreno_smmu specific).

2021-07-26drm/amdgpu: Avoid printing of stack contents on firmware load errorJiri Kosina
In case when psp_init_asd_microcode() fails to load ASD microcode file, psp_v12_0_init_microcode() tries to print the firmware filename that failed to load before bailing out. This is wrong because: - the firmware filename it would want it print is an incorrect one as psp_init_asd_microcode() and psp_v12_0_init_microcode() are loading different filenames - it tries to print fw_name, but that's not yet been initialized by that time, so it prints random stack contents, e.g. amdgpu 0000:04:00.0: Direct firmware load for amdgpu/renoir_asd.bin failed with error -2 amdgpu 0000:04:00.0: amdgpu: fail to initialize asd microcode amdgpu 0000:04:00.0: amdgpu: psp v12.0: Failed to load firmware "\xfeTO\x8e\xff\xff" Fix that by bailing out immediately, instead of priting the bogus error message.

This reverts commit 4192f7b5768912ceda82be2f83c87ea7181f9980. It is not true (as stated in the reverted commit changelog) that we never unmap the BAR on failure; it actually does happen properly on amdgpu_driver_load_kms() -> amdgpu_driver_unload_kms() -> amdgpu_device_fini() error path. What's worse, this commit actually completely breaks resource freeing on probe failure (like e.g. failure to load microcode), as amdgpu_driver_unload_kms() notices adev->rmmio being NULL and bails too early, leaving all the resources that'd normally be freed in amdgpu_acpi_fini() and amdgpu_device_fini() still hanging around, leading to all sorts of oopses when someone tries to, for example, access the sysfs and procfs resources which are still around while the driver is gone.

2021-07-26drm/i915/display: split DISPLAY_VER 9 and 10 in intel_setup_outputs()Lucas De Marchi
Commit 5a9d38b20a5a ("drm/i915/display: hide workaround for broken vbt in intel_bios.c") moved the workaround for broken or missing VBT to intel_bios.c. However is_port_valid() only protects the handling of different skus of the same display version. Since in intel_setup_outputs() we share the code path with version 9, this would also create port F for SKL/KBL, which does not exist. Missing VBT can be reproduced when starting a headless QEMU with no opregion available. Avoid the issue by splitting versions 9 and 10 in intel_setup_outputs(), which also makes it more clear what code path it's taking for each version. v2: move generic display version after Geminilake since that one has a different set of outputs Fixes: 5a9d38b20a5a ("drm/i915/display: hide workaround for broken vbt in intel_bios.c") Cc: Jani Nikula <jani.nikula@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reported-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Tested-by: Christoph Hellwig <hch@lst.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210722232922.3796835-1-lucas.demarchi@intel.com (cherry picked from commit ec387b8ff8d757561369be9a280cf63f23bbb926) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2021-07-25octeontx2-pf: Fix interface down flag on errorGeetha sowjanya
In the existing code while changing the number of TX/RX queues using ethtool the PF/VF interface resources are freed and reallocated (otx2_stop and otx2_open is called) if the device is in running state. If any resource allocation fails in otx2_open, driver free already allocated resources and return. But again, when the number of queues changes as the device state still running oxt2_stop is called. In which we try to free already freed resources leading to driver crash. This patch fixes the issue by setting the INTF_DOWN flag on error and free the resources in otx2_stop only if the flag is not set.

2021-07-25octeontx2-af: Fix PKIND overlap between LBK and LMAC interfacesGeetha sowjanya
Currently PKINDs are not assigned to LBK channels. The default value of LBK_CHX_PKIND (channel to PKIND mapping) register is zero, which is resulting in a overlap of pkind between LBK and CGX LMACs. When KPU1 parser config is modified when PTP timestamping is enabled on the CGX LMAC interface it is impacting traffic on LBK interfaces as well. This patch fixes the issue by reserving the PKIND#0 for LBK devices. CGX mapped PF pkind starts from 1 and also fixes the max pkind available.

2021-07-24can: mcp251xfd: mcp251xfd_irq(): stop timestamping worker in case error in IRQMarc Kleine-Budde
In case an error occurred in the IRQ handler, the chip status is dumped via devcoredump and all IRQs are disabled, but the chip stays powered for further analysis. The chip is in an undefined state and will not receive any CAN frames, so shut down the timestamping worker, which reads the TBC register regularly, too. This avoids any CRC read error messages if there is a communication problem with the chip.
