From: Yegor Yefremov <yegorslists@xxxxxxxxxxxxxx> This series adds MCTRL_GPIO support to 8250 driver. In order to do so following changes had to be made: * read/write calls to MCR register were put into new routines: serial8250_out_MCR() and serial8250_in_MCR(). These new routines now access both UARTs MCR register as also read/write GPIO pins for RTS/DTR/OUT1/OUT2 * MCTRL_GPIO framwork had routines to set MCR and to read MSR, reading MCR related GPIO signals was missing, hence mctrl_gpio_get_outputs() routine was implemented * RS485 half-duplex was missing RX activation after TX * mctrl_gpio_irq_handle() got IRQ locking Yegor Yefremov (5): tty/serial/8250: fix RS485 half-duplex RX tty/serial/8250: make UART_MCR register access consistent serial: mctrl_gpio: add modem control read routine serial: mctrl_gpio: add IRQ locking tty/serial/8250: use mctrl_gpio helpers Documentation/devicetree/bindings/serial/8250.txt | 19 +++++++ drivers/tty/serial/8250/8250.h | 51 ++++++++++++++++++ drivers/tty/serial/8250/8250_core.c | 4 ++ drivers/tty/serial/8250/8250_omap.c | 35 ++++++------ drivers/tty/serial/8250/8250_port.c | 65 ++++++++++++++--------- drivers/tty/serial/8250/Kconfig | 1 + drivers/tty/serial/serial_mctrl_gpio.c | 23 ++++++++ drivers/tty/serial/serial_mctrl_gpio.h | 15 +++++- include/linux/serial_8250.h | 1 + 9 files changed, 172 insertions(+), 42 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
