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.

Hi everyone,
This is v2 of my A31 HDMI support series. As it's been some time
since the first version and I've rebased my series a couple times
to merge newer changes done by others, the changelog might not be
complete.
Changes since v1:
- Core changes to sun4i-drm to support two display pip
All the A31/A31s devices I own have some kind of HDMI connector wired
to the dedicated HDMI pins on the SoC:
- A31 Hummingbird (standard HDMI connector, display already enabled)
- Sinlinx SinA31s (standard HDMI connector)
- MSI Primo81 tablet (micro HDMI connector)
Enable the display pipeli
Allwinner SoCs typically have two PLLs reserved for video related usage.
At the moment we only support using the first one to feed the HDMI
transmitter block's TMDS clock.
Let the HDMI encoder's TMDS clock go through all of its parents when
calculating possible clock rates. This allows usage of th
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.

The HDMI controller found in earlier Allwinner SoCs have slight
differences between the A10, A10s, and the A31:
- Need different initial values for the PLL related registers
- Different behavior of the DDC and TMDS clocks
- Different register layout for the DDC portion
- Separate DDC pa
The 2x outputs of the 2 video PLL clocks are directly used by the
HDMI controller block.

For maintaining consistency with kernel coding style replace
reference/unreference in ref counting functions with get/put.
The following cocci script was used to generate the tilcdc patch:

This patchset introduces drm_dev_get() and drm_dev_put() functions that are
intented to be replacements for drm_dev_{ref/unref}.
Then all usages of ref/reference and unref/unreference suffixes are replaced by
get/put reference count functions in tilcdc. The following cocci script was used
to make
Hello,
I am working on task "Better manual upload for atomic" in kernel gpu
subsystem.
When duplicating the crtc state I need to change drm_rect x2 and y2 to
MAX_INT.
I didn't get what is MAX_INT over here. Also, how am I supposed to test my
code?
It will be really helpful if you can suggest someth
Reference counting functions in the kernel typically use get/put suffixes. For
maintaining coding style consistency, introduce drm_dev_{get/put} functions. All
callers of drm_dev_ref() API have been converted in this patch and hence it has
been dropped while the drm_dev_unref() API with non-trivial

The hdmi-codec interface added in this patch is required to properly
support HDMI audio. Currently the audio part of the SoC internal
HDMI transmitter is configured with fixed values, which makes HDMI
audio working by chance, only on boards having an external audio
