The HDMI controller in the A31 SoC is slightly different from the earlier version. In addition to the TMDS clock and DDC controls, this version now takes a second DDC clock input. Add a compatible string for it, and add the DDC clock input to the list of clocks required. Signed-off-by:

On SoCs with two display pipelines, it is possible that the two pipelines are active at the same time, with potentially incompatible dot clocks. Let the HDMI encoder's TMDS clock go through all of its parents when calculating possible clock rates. This allows usage of the second video PLL as its parent. Signed-off-by:

The HDMI driver is written with readl/writel I/O to the registers. However, to support the A31 variant, which has a different layout for the DDC registers, it was recommended to use regfields to have a cleaner implementation. To use regfields, we need to create an underlying regmap. This patch only adds the regmap. It does not convert the existing driver accesses to use regmap. Signed-off-by:

The HDMI driver enables the bus and mod clocks in the bind function, but does not disable them if it then bails our due to any errors. Neither does it disable the clocks in the unbind function. Fix this by adding a proper error path to the bind function, and clk_disable_unprepare calls to the unbind function. Also rename the err_cleanup_connector label to err_cleanup_encoder, since it is the encoder that gets cleaned up. Fixes: 9c568101 ("drm/sun4i: Add HDMI support") Signed-off-by:

Chen-Yu Tsai authored
Different SoCs have different muxing options and values for the TCON outputs. Instead of stuffing every possibility in sun4i_tcon_set_mux(), add a callback pointer to sun4i_tcon_quirks that each TCON variant can use to provide muxing support. The current muxing options in sun4i_tcon_set_mux() for sun5i-a13 are moved to a new sun5i-specific callback function. Since the new callback replaces what the .has_unknown_mux field in tcon quirks did in the past, the field is removed. Signed-off-by:

This function is the pendant of drm_of_find_panel_or_bridge() to remove a previously allocated panel_bridge. Given a specific port and endpoint it remove the panel bridge. Since drm_panel_bridge_remove() will check that bridge parameter is not NULL and is a real drm_panel_bridge and no a simple bridge it is safe to call it directly. Signed-off-by:

When dma_fence_get_rcu() fails to acquire a reference it doesn't necessary mean that there is no fence at all. It usually mean that the fence was replaced by a new one and in this situation we certainly want to have the new one as result and *NOT* NULL. v2: Keep extra check after dma_fence_get_rcu().

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.

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 -
