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 Link:https://lore.kernel.org/linux-amlogic/20220110085604.18042-1-yu.tu@xxxxxxxxxxx/ .../bindings/serial/amlogic,meson-uart.yaml | 10 +- drivers/tty/serial/meson_uart.c | 244 ++++++++++++------ 2 files changed, 177 insertions(+), 77 deletions(-) -- 2.33.1
