[PATCH V5 0/5] The UART driver compatible with

[Yu Tu]

Using the common Clock code to describe the UART baud rate
clock makes it easier for the UART driver to be compatible
with the baud rate requirements of the UART IP on different
meson chips. Add Meson S4 SoC compatible.

Yu Tu (5):
  dt-bindings: serial: meson: Drop legacy compatible.
  tty: serial: meson: Move request the register region.
  tty: serial: meson: Using the common clock code describe.
  tty: serial: meson: Make some bit of the REG5 register writable.
  tty: serial: meson: Added S4 SOC compatibility.

V4 -> V5: Change error format.
V3 -> V4: Change CCF to describe the UART baud rate clock as discussed
in the email.
V2 -> V3: add compatible = "amlogic,meson-gx-uart". Because it must change
the DTS before it can be deleted
V1 -> V2: Use CCF to describe the UART baud rate clock.Make some changes as
discussed in the email
