Hello everyone,

This series adds the support for the Rockchip RK3288w which
is a revision of the RK3288. It is mostly the same SOC except
for, at least, one clock tree which is different. This difference
is only known by the BSP kernel repository [1].

Currently, the mainline kernel will not hang on rk3288w but it is
probably by "chance" because we got an issue on a lower kernel version.

According to Rockchip's U-Boot [2], the rk3288w can be detected using
the HDMI revision number (= 0x1A) in this version of the SOC.
Not to rely on U-Boot about the compatible, the patch 01 will handle
the detection of the HDMI version in the rockchip subsystem.

Let me know what you think!

Best regards,
Mylène Josserand
