[PATCH 5.11 621/775] drm/nouveau/kms: handle mDP connectors
by Greg Kroah-Hartman 01 Mar '21

01 Mar '21

From: Karol Herbst <kherbst(a)redhat.com> commit d1f5a3fc85566e9ddce9361ef180f070367e6eab upstream. In some cases we have the handle those explicitly as the fallback connector type detection fails and marks those as eDP connectors. Attempting to use such a connector with mutter leads to a crash of mutter as it ends up with two eDP displays. Information is taken from the official DCB documentation.

[PATCH V4 0/2] Fix WLED FSC Sync and brightness Sync settings
by Kiran Gunda 01 Mar '21

01 Mar '21

This patch series has the following two WLED fixes 1. As per the current implementation, for WLED5, after the FSC (Full Scale Current) update the driver is incorrectly toggling the MOD_SYNC register instead of toggling the SYNC register. The patch 1/2 fixes this by toggling the SYNC register after FSC update. 2. Currently, the sync bits are set-then-cleared after FSC and brightness update. As per hardware team recommendation the FSC and brightness sync takes place from clear-then-set transition of the sync bits. The patch 2/2 fies this issue. Changes from V3: 1. Updated the patch description as per Daneil's suggestion. 2. Added Daniel's "Reviewed-by" tag for patch 2/2. 3. Updated the cover letter to use "set" and "clear" properly. Changes from V2: 1. Added Daniel's "Reviewed-by" tag for patch 1/2. 2. Updated the patch 2/2 description with "set" and "clear" terminology instead of "1" and "0". 3. Updated the cover letter with "set" and "clear" terminology instead of "1" and "0". Changes from V1: 1. Updated the cover letter. 2. Updated the description of the patches as per Daniel's suggestion.

[PATCH 5.10 355/663] kselftests: dmabuf-heaps: Fix Makefiles inclusion of the kernels usr/include dir

From: John Stultz <john.stultz(a)linaro.org> [ Upstream commit 64ba3d591c9d2be2a9c09e99b00732afe002ad0d ] Copied in from somewhere else, the makefile was including the kerne's usr/include dir, which caused the asm/ioctl.h file to be used. Unfortunately, that file has different values for _IOC_SIZEBITS and _IOC_WRITE than include/uapi/asm-generic/ioctl.h which then causes the _IOCW macros to give the wrong ioctl numbers, specifically for DMA_BUF_IOCTL_SYNC.
