Factor out the uart save/restore functionality instead of having the same code several times in the driver.

+ unsigned int *ucr1, + unsigned int *ucr2, + unsigned int *ucr3)Can we define something like 'struct imx_port_ucrs' to contains these?Yes, we could have different function names above and use a struct. I implemented what Sascha asked for in http://www.spinics.net/lists/arm-kernel/msg144960.html though: -- Sascha wrote: -- I'm thinking about: imx_console_mode(struct uart_port *port, u32 *ucr1, u32 *ucr2, u32 *ucr2); imx_console_restore(struct uart_port *port, u32 ucr1, u32 ucr2, u32 ucr3); -- Sascha end -- It seems Shawn proposes imx_port_ucrs_save(struct uart_port *port, struct *imx_port_ucrs); imx_port_ucrs_restore(struct uart_port *port, struct *imx_port_ucrs); (?) Sascha, Shawn: Could you agree on what we should use? Once you agreed, I will send an update of both two patches.
Please Cc Alan Cox [off-list ref] for these patches. Though we could possibly send them through arm-soc tree, we need to ask for his ack. -- Regards, Shawn
