omap-serial: use mctrl_gpio helpers
This patch is based on Richard Genoud' patch adding generic GPIO support [1] and my patch adding get_direction() functionality to OMAP's GPIO driver [2]. So far RTS/DTR are working both as modem control outputs and RTS as RS-485 2-wire controller. CTS/DSR/DSR/RI are generating interrupts. Richard, Greg, what is the status of [1]? It seems like it will be available in 3.16 first? TODO: 1. remove rts_gpio from uart_omap_port 2. perhaps add rts_gpiod to uart_omap_port to avoid numerous invocations of rts_gpiod = mctrl_gpio_to_gpiod(up-gpios, UART_GPIO_RTS); 3. add device tree documentation Yegor [1] http://comments.gmane.org/gmane.linux.serial/13967 [2] http://www.spinics.net/lists/arm-kernel/msg325162.html -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
