* serial: serial-uclass: Use force parameter in stdio_deregister_dev()Stefan Roese2017-05-171-1/+1
| | | | | | | | | | | | | On my x86 platform I've noticed, that calling dm_uninit() or the new function dm_remove_devices_flags() does not remove the desired device at all. Debugging showed, that the serial uclass returns -EPERM in serial_pre_remove(). This patch sets the force parameter when calling stdio_deregister_dev() resulting in a removal of the device.

With that changed we can drop all defines of CONFIG_OMAP. While in here, CONFIG_OMAP3430 is only defined and then never used, so drop. Signed-off-by: Tom Rini <trini@konsulko.com>

| | | | | | | | | | | | | | | | | | | | | | | | | Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor" breaks u-boot commandline working with long commands sending to the board. Since the above patch, you have to setup the fcr register. For board/archs which enable OF_PLATDATA, the new field fcr in struct ns16550_platdata is not filled with a default value ... This leads in not setting up the uarts fifo, which ends in problems, when you send long commands to u-boots commandline. Detected this issue with automated tbot tests on am335x based shc board. The error does not popup, if you type commands. You need to copy&paste a long command to u-boots commandshell (or send a long command with tbot) Possible boards/plattforms with problems: ./arch/arm/cpu/arm926ejs/lpc32xx/devices.c ./arch/arm/mach-tegra/board.c ./board/overo/overo.c ./board/quipos/cairo/cairo.c ./board/logicpd/omap3som/omap3logic.c ./board/logicpd/zoom1/zoom1.c ./board/timll/devkit8000/devkit8000.c ./board/lg/sniper/sniper.c ./board/ti/beagle/beagle.c ./drivers/serial/serial_rockchip.c Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Tested-by: Adam Ford <aford173@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com>
