Subject[PATCH v2,0/3] tty/serial: meson_uart: add support for core clock handling
To be able to use the three none AO uarts of the s905 SoCs (uart_A, uart_B
& uart_C), the core clock has to be enabled. (see chapter 22.3 of the
public s905 data sheet) At least the u-boot of my s905 based media player
(netxeon minimx) doesn't do this. so the driver must do it.

This patch set does:
- exposes the clock ids to the dtb
- adds documentation for the dt-bindings of meson_uart
- adds the core clock handling to the driver

The patchset is based on the branch master of the repository in [1]

Changes since v1
- use git to produce the patch set
- added the clock ids for uart_B and uart_C

None of the available s905 dts use uart_A actively. So there is no patch
for any of the existing dts files.
