[PATCH v2 1/3] serial: altera: ensure port->regshift is honored consistently

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Most register accesses in the altera driver honor port->regshift by
using altera_uart_writel(). There are a few accesses however that were
missed when the driver was converted to use port->regshift and some
others were added later in commit 4d9d7d896d77 ("serial: altera_uart:
add earlycon support").

Fixes: 2780ad42f5fe ("tty: serial: altera_uart: Use port->regshift to store bus shift")
