This is a combination of Linux commits:
6e69052f01d91 ("clk: rockchip: Add CLK_SET_RATE_PARENT to the HDMI reference clock on rk3568")
ff3187eabb5ce ("clk: rockchip: drop CLK_SET_RATE_PARENT from dclk_vop* on rk3568")
These are needed for proper HDMI clock settings on RK3568.

Linux has three different structures to describle video modes: The
FB subsystem specific struct fb_videomode, the DRM subsystem specific
struct drm_display_mode and one to rule them all, struct videomode.
In barebox we used to stick to struct fb_videomode, but as new graphic
drivers are likely to be derived from the DRM subsystem, add the
remaining struct types and add functions to convert between them.
The functions are taken from Linux with some adjustments of the function
names for consistency.

get the new formats.

From: Sascha Hauer @ 2024-09-27 10:37 UTC (permalink / raw)
To: open list:BAREBOX
This adds the Designware HDMI driver from Linux-6.10. The code is directly
taken from Linux with the necessary adjustments for the barebox API.
Audio support has been removed.

From: Sascha Hauer @ 2024-09-27 10:37 UTC (permalink / raw)
To: open list:BAREBOX
The Linux dw-hdmi driver is based on a driver which originally was
written specifically for the i.MX and was converted later to a generic
dw-hdmi driver. The barebox driver is still based on the original Linux
driver. We just merged the dw-hdmi driver. With this patch we now get
rid of the i.MX specific driver and use the generic one.

This adds a pointer to the base framebuffer to struct fb_info
in case the framebuffer is an overlay. As overlays do not have modes,
accept them in fb_enable() even when it doesn't have a mode.

it for aarch64 as it is useful for mapping framebuffer memory.

This adds support for the Rockchip VOP2 video core found on the Rockchip
SoCs RK3566, RK3568 and RK3588. The code is based on the Linux driver
and has been heavily stripped down for barebox. Support for the cluster
windows has been removed, also support for YUV modes has been dropped.

Unfortunately, this causes the VOP2 driver to hang my CPU on the first
MMIO access, unless I move it back to late_initcall level.
I added *_ensure_probed for the Rockchip I/O domain device, but this
didn't help and I am not sure where exactly (device dependency? timing?)
the problem is. Any ideas?
Thanks,
Ahmad

No idea, sorry.
I switched back to late_platform_driver() while applying.
