drm/imx: fix crtc vblank state regression
drm/imx: Add active plane reconfiguration support
Choose console BPP that supports RGB and remove the old fbdev bpp
selection code. LCDC on AM335x has red and blue wires switched between
24 bit and 16 bit colors. If 24 format is wired for RGB colors, the 16
bit format is wired for BGR. drm_fbdev_cma_init() does not currently
like anything else but RGB formats, so we must choose such bytes per
pixel value that supports RGB.

Add "blue-and-red-wiring"-device tree property and update devicetree
binding document.
The red and blue components are reversed between 24 and 16 bit modes
on am335x LCDC output pins. To get 24 RGB format the red and blue
wires has to be crossed and this in turn causes 16 colors output to be
in BGR format. With straight wiring the 16 color is RGB and 24 bit is
BGR.
The new property describes whether the red and blue wires are crossed
or not. If the property is not present or its value is not recognized
the legacy mode is assumed. The legacy configuration supports RGB565,
RGB888 and XRGB8888 formats. However, depending on wiring, the red and
blue colors are swapped in either 16 or 24-bit color modes.

Write DMA base and ceiling address with a single instruction, if
available. This should make it more unlikely that LCDC would fetch the
DMA addresses in the middle of an update. Having bad combination of
addresses in dma base and ceiling (e.g base > ceiling) can cause
unpredictaple behavior in LCDC.

The LCDC seems to expect its framebuffer ceiling address pointer to be
an inclusive bound. The IP rev2 seems to cope with that but rev1 (as
found on the LCDK) don't.
Also note that this is what the framebuffer code does in da8xx-fb.c.
Since, as the TRM puts it, "The 2 LSBs are hardwired to 00b", the
dma_addr_t can be decremented without cast.
I tested it with a v2 (AM335x, rev 0x4F201000) and an LCDK (v1).

The KMS helpers (drm_atomic_helper_check_modeset/mode_fixup) pass
encoder->bridge directly to drm_bridge_mode_fixup, which expects a
valid pointer, or NULL (in which case it just returns).
Clear encoder->bridge if a bridge is not found, instead of keeping
the ERR_PTR value.
Since other drm_bridge functions also follow this pattern of checking
for a non-NULL pointer, we can drop the ifs around the calls and just
pass the pointer directly.

drm_kms_helper_poll_enable_locked() should check if we have delayed event
pending and if we have, schedule the work to run without delay.
Currently the output_poll_work is only scheduled if any of the connectors
have DRM_CONNECTOR_POLL_CONNECT or DRM_CONNECTOR_POLL_DISCONNECT with
DRM_OUTPUT_POLL_PERIOD delay. It does not matter if we have delayed event
already registered to be handled. The detection will be delayd by
DRM_OUTPUT_POLL_PERIOD in any case.
Furthermore if none of the connectors are marked as POLL_CONNECT or
POLL_DISCONNECT because all connectors are either POLL_HPD or they are
always connected: the output_poll_work will not run at all even if we
have delayed event marked.
When none of the connectors require polling, their initial status change
from unknown to connected/disconnected is not going to be handled until
the first kms application starts or if we have fb console enabled.
Note that in general the output poll work should be enabled already
when this happens, but at driver load usually the first probe happens
before the output polling is enabled. This patch fixes this case.

Even if PR3 support is available on the bridge, it will not be used if
the PCI layer considers it unavailable (i.e. on all laptops from 2013
and 2014). Ensure that this condition is checked to allow a fallback to
the Optimus DSM for device poweroff.
Initially I wanted to call pci_d3cold_enable before checking bridge_d3
(in case the user changed d3cold_allowed), but that is such an unlikely
case and likely fragile anyway. The current patch is suggested by Mika
in http://www.spinics.net/lists/linux-pci/msg52599.html
