serial: fix mctrl helper functions

2015-10-18T04:21:07+00:00

A recent patch to create common helper functions for modem control lines created empty helper functions in a header file, but accidentally did not mark them as 'static inline', which causes build errors: drivers/tty/serial/mxs-auart.o: In function `mctrl_gpio_enable_ms': mxs-auart.c:(.text+0x171c): multiple definition of `mctrl_gpio_enable_ms' drivers/tty/serial/clps711x.o:clps711x.c:(.text+0x768): first defined here drivers/tty/serial/mxs-auart.o: In function `mctrl_gpio_disable_ms': mxs-auart.c:(.text+0x1720): multiple definition of `mctrl_gpio_disable_ms' drivers/tty/serial/clps711x.o:clps711x.c:(.text+0x76c): first defined here This adds the missing annotation, so the functions do not get placed in each object file.

serial: mctrl_gpio: implement interrupt handling

This allows to reduce the per-driver boiler plate considerably. Signed-off-by: Uwe Kleine-König Reviewed-by: Nicolas Ferre Signed-off-by: Greg Kroah-Hartman

serial: mctrl-gpio: rename init function

2015-10-04T17:46:43+00:00

This is done before adding more functionality to the init function with the existing name. As this new functionality conflicts with stuff drivers are required to implement themselves up to I want to convert them one by one to make reviewing and reverting more easy in case I broke something. Once mctrl_gpio_init is there and all drivers are converted mctrl_gpio_init_noauto can be removed again. Signed-off-by: Uwe Kleine-König Signed-off-by: Greg Kroah-Hartman

tty/serial: Add GPIOLIB helpers for controlling modem lines

2014-05-28T19:49:14+00:00

This patch add some helpers to control modem lines (CTS/RTS/DSR...) via GPIO. This will be useful for many boards which have a serial controller that only handle CTS/RTS pins (or even just RX/TX).
