768e9e61b3 drm: renesas: Add RZ/G2L DU Support 
The LCD controller is composed of Frame Compression Processor (FCPVD),
Video Signal Processor (VSPD), and Display Unit (DU).

It has DPI/DSI interfaces and supports a maximum resolution of 1080p
along with 2 RPFs to support the blending of two picture layers and
raster operations (ROPs).

The DU module is connected to VSPD. Add RZ/G2L DU support for RZ/G2L
alike SoCs.

c1bb7f9f1e dt-bindings: display: Document Renesas RZ/G2L DU bindings 
The RZ/G2L LCD controller is composed of Frame Compression Processor
(FCPVD), Video Signal Processor (VSPD), and Display Unit (DU).

The DU module supports the following hardware features
− Display Parallel Interface (DPI) and MIPI LINK Video Interface
− Display timing master
− Generates video timings
− Selecting the polarity of output DCLK, HSYNC, VSYNC, and DE
− Supports Progressive
− Input data format (from VSPD): RGB888, RGB666
− Output data format: same as Input data format
− Supporting Full HD (1920 pixels x 1080 lines) for MIPI-DSI Output
− Supporting WXGA (1280 pixels x 800 lines) for Parallel Output

This patch documents the DU module found on RZ/G2L LCDC.

two separate register spaces namely "common" and "common1" which can be

The common1 register space has similar set of configuration registers as
supported in common register space except the global configuration
registers which are exclusive to common region.

This adds binding for "common1" register region too as supported by the
hardware.

Rename meson_encoder_{cvbs,dsi,hdmi}_init() to
meson_encoder_{cvbs,dsi,hdmi}_probe() so it's clear that these functions
are used at probe time during driver initialization. Also switch all
error prints inside those functions to use dev_err_probe() for
consistency.

This makes the code more straight forward to read and makes the error
prints within those functions consistent (by logging all -EPROBE_DEFER
with dev_dbg(), while actual errors are logged with dev_err() and get
the error value printed).

aa1267e673 drm: ci: use clk_ignore_unused for apq8016 
If the ADV7511 bridge driver is compiled as a module, while DRM_MSM is
built-in, the clk_disable_unused congests with the runtime PM handling
of the DSI PHY for the clk_prepare_lock(). This causes apq8016 runner to
fail without completing any jobs ([1]). Drop the BM_CMDLINE which
duplicate the command line from the .baremetal-igt-arm64 clause and
enforce the clk_ignore_unused kernelarg instead to make apq8016 runner
work.

8084a5b589 fbdev/efifb: Remove framebuffer relocation tracking 
If the firmware framebuffer has been reloacted, the sysfb code
fixes the screen_info state before it creates the framebuffer's
platform device. Efifb will automatically receive a screen_info
with updated values. Hence remove the tracking from efifb.

78aa89d1df firmware/sysfb: Update screen_info for relocated EFI framebuffers 
On ARM PCI systems, the PCI hierarchy might be reconfigured during
boot and the firmware framebuffer might move as a result of that.
The values in screen_info will then be invalid.

Work around this problem by tracking the framebuffer's initial
location before it get relocated; then fix the screen_info state
between reloaction and creating the firmware framebuffer's device.

This functionality has been lifted from efifb. See the commit message
of commit 55d728a40d ("efi/fb: Avoid reconfiguration of BAR that
covers the framebuffer") for more information.
