- Reparenting for muxes
- Clock rate setting through generic dividers without reparenting
Support is only added to the Composite VPU and VAPB clocks in order
to support the Video Processing Unit Power Domain clock setup.

power: domain: Add the VPU Power Domain driver
The Amlogic Meson SoCs embeds a specific Power Domain dedicated to the
Video Processing Unit.
This patch implements support for this power domain in preparation of the
future support for the Video display support in U-Boot.
This driver will depend on changes in the clock driver to handle the setup
of the VPU and VAPB clocks configured from DT using assigned-clocks entries.

arch: types.h: factor out fixed width typedefs to int-ll64.h
All architectures have the same definition for s8/16/32/64
and u8/16/32/64.
Factor out the duplicated code into <asm-generic/int-ll64.h>.
BTW, Linux unified the kernel space definition into int-ll64.h
a few years ago as you see in Linux commit 0c79a8e29b5f
("asm/types.h: Remove include/asm-generic/int-l64.h").

Remove CONFIG_USE_STDINT
You do not need to use the typedefs provided by compiler.
Our compilers are either IPL32 or LP64. Hence, U-Boot can/should
always use int-ll64.h typedefs like Linux kernel, whatever the
typedefs the compiler internally uses.
