Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.
Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.
This was made using the coccinelle script below:

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.
The conversion was done using the coccinelle script below, built tested on
all the drivers.

Most drivers call the argument to the plane atomic_check hook simply
state, which is going to conflict with the global atomic state in a

A non-const structure containing function pointers is a possible attack
vector. The drm_driver structure is already const in most drivers, but
there are a few exceptions. Constify the structure in the drivers that
don't need to modify at, as a low-hanging fruit. The rest of the drivers
will need a more complex fix.

Having the array truncated to one entry seems intentional, so add
a range check before indexing it to make it clearer what is going
on and shut up the warning.
I received the warning from the kernel test robot after a private
patch that turns on Warray-bounds unconditionally.

The NULL checking isn't done consistently in this function and it leads
to a static checker warning:

Fortunately "drm" cannot be NULL at this point so the check can just be

The Intel Keem Bay display controller is only present on Intel Keem Bay
SoCs. Hence add a dependency on ARCH_KEEMBAY, to prevent asking the
user about this driver when configuring a kernel without Intel Keem Bay
platform support.
Note that:
1. The dependency on ARM is dropped, as Keem Bay SoCs are only
supported in arm64 kernel builds,
2. The dependencies on OF and COMMON_CLK can be dropped for
compile-testing, as the driver builds fine regardless.

This is a basic KMS atomic modesetting display driver for KeemBay family of
SOCs. Driver has no 2D or 3D graphics. It calls into the ADV bridge

Single CRTC with LCD controller->mipi DSI->ADV bridge
Only 1080p resolution and single plane is supported at this time.
