This driver communicates with the Atmel microcontroller for sequencing the poweron of the TC358762 DSI-DPI bridge and controlling the backlight PWM. v2: Set the same default orientation as the closed source firmware used, which is the best for viewing angle. v3: Rewrite as an i2c client driver after bridge driver rejection. v4: Finish probe without the DSI host, using the new delayed registration, and attach to the host during mipi_dsi_driver probe. v5: Rework to drop the "probe without DSI host" mode again, now that vc4 will create the host early on. v6: Drop unused brightness #define (noticed by Thierry) Signed-off-by: Eric Anholt <eric@anholt.net> Link: https://patchwork.freedesktop.org/patch/msgid/20170927193654.12609-4-eric@anholt.netReviewed-by: Archit Taneja <architt@codeaurora.org> Acked-by: Thierry Reding <treding@nvidia.com>

SiI9234 transmitter converts eTMDS/HDMI signal to MHL 1.0. It is controlled via I2C bus. Its interaction with other devices in video pipeline is performed mainly on HW level. The only interaction it does on device driver level is filtering-out unsupported video modes, it exposes drm_bridge interface to perform this operation.

Commit 669c9215 ("drm/atomic: Make async plane update checks work as intended, v2.") assumed incorrectly that if only 1 plane is matched in the loop, the variables will be set to that plane. In reality we reset them to NULL every time a new plane was iterated. This behavior is surprising, so fix this by making the for loops only assign the variables on a match. When we have not added all the planes/crtc/connector to the state, and there's a few NULL ones after the last one we iterated, te assumption is broken that the pointers will hold the values from the last loop iteration, which holds true for all other for_each macros we're using. Except of course the iterator pointer itself, but that one really is entirely internal.

fbdev is in maintenance only, except that it's still used by drm through the drm fbdev emulation, to be able to use fbcon. And people might want to sometimes extend fbcon to enable new features for drm drivers, e.g. Hans' panel orientation work. The problem is that when those patches only touch fbdev code they'll never show up on drm developer's radar, which means we end up with designs that don't really fit whell into the full stack. That happened a bit with the panel orientation work, where an fbcon patch made it into 4.14, implementing a design that won't really work on the drm side. Which means we now have to redo things, and on top coordinate 2 subsystem trees. Since fbdev is super low-volume we can prevent this in the future by simply adding the dri-devel mailing list to the fbdev subsystem.

Pull timer fixes from Thomas Gleixner: "This adds a new timer wheel function which is required for the conversion of the timer callback function from the 'unsigned long data' argument to 'struct timer_list *timer'. This conversion has two benefits: 1) It makes struct timer_list smaller 2) Many callers hand in a pointer to the timer or to the structure containing the timer, which happens via type casting both at setup and in the callback. This change gets rid of the typecasts. Once the conversion is complete, which is planned for 4.15, the old setup function and the intermediate typecast in the new setup function go away along with the data field in struct timer_list. Merging this now into mainline allows a smooth queueing of the actual conversion in the affected maintainer trees without creating dependencies" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: um/time: Fixup namespace collision timer: Prepare to change timer callback argument type
