+ OCMEM support to enable the couple generations that had shared OCMEM
  rather than GMEM exclusively for the GPU (late a3xx and I think basically
  all of a4xx).  Bjorn and Brian decided to land this through the drm

We haven't done any backmerge for a while due to the merge window, and it
starts to become an issue for komeda. Let's bring 5.4-rc1 in.

drm/msm/hdmi: Convert to use GPIO descriptors

2019-09-03T23:16:58+00:00

This switches the MSM HDMI code to use GPIO descriptors.
Normally we would fetch the GPIOs from the device with the
flags GPIOD_IN or GPIOD_OUT_[LOW|HIGH] to set up the lines
immediately, but since the code seems eager to actively
drive the lines high/low when turning HDMI on and off, we
just fetch the GPIOs as-is and keep the code explicitly
driving them.

The old code would try legacy bindings (GPIOs without any
"-gpios" suffix) but this has been moved to the gpiolib
as a quirk by the previous patch.

drm/msm: drop use of drmP.h

2019-09-03T23:16:57+00:00

Drop the deprecated drmP.h header file, and trim msm_drv.h
to the relevant include files.

This resulted in a suprisingly many edits as many files relied
on headers included via msm_drv.h.
But msm_drv.h is not supposed to carry include files it do not need, so
the individual files have to include what extra they needs.

v2:
- Rebased on top of https://gitlab.freedesktop.org/drm/msm.git msm-next

drm/msm: Use drm_attach_bridge() to attach a bridge to an encoder

2019-08-28T20:22:49+00:00

This is part of our attempt to make the bridge chain a double-linked
list based on the generic list helpers. In order to do that, we must
patch all drivers manipulating the encoder->bridge field directly.
