Re: [PATCH] tty: serial: meson: Make the bit24 and bit [26,27] of the UART_REG5 register writable

Hi All,
I'm really sorry for sending the wrong specified file. Please ignore the email. I will resend V4.

The UART_REG5 register defaults to 0. The console port is set in
ROMCODE. But other UART ports default to 0, so make bit24 and
bit[26,27] writable so that the UART can choose a more
appropriate clock.
