2015-11-20ns16550: unify serial_x86Thomas Chou
Unify serial_x86, and use the generic binding. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-11-20ns16550: add generic binding to unify the driversThomas Chou
Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

2015-11-20ns16550: change map_sysmem to map_physmemThomas Chou
Change map_sysmem() to map_physmem(,,MAP_NOCACHE). Though map_sysmem() can be used to map system memory, it might be wrong to use it for I/O ports. The map_physmem() serves the same purpose to translate physical address to virtual address with the additional flag to take care of cache property. Most drivers use map_physmem() since I/O ports access should be uncached. As ns16550 is a driver, it should use map_physmem() rather than map_sysmem().

2015-11-19dm: test: usb: sandbox: Add keyboard tests for sandboxSimon Glass

2015-11-19usb: sandbox: Add a USB emulation driverSimon Glass
Add a simple USB keyboard driver for sandbox. It provides a function to 'load' it with input data, which it will then stream through to the normal U-Boot input subsystem. When the input data is exhausted, the keyboard stops providing data. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-11-19dm: usb: Remove inactive children after a bus scanSimon Glass
Each scan of the USB bus may return different results. Existing driver-model devices are reused when found, but if a device no longer exists it will stay around, de-activated, but bound. Detect these devices and remove them after the scan completes. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-11-19sandbox: Enable console recording and silent consoleSimon Glass
Allow console recording so that tests can use it. Also allow the console output to be suppressed, to reduce test output 'noise'. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-11-19console: Add a console bufferSimon Glass
It is useful to be able to record console output and provide console input via a buffer. This provides sandbox with the ability to run a command and check its output. If the console is set to silent then no visible output is generated. This also provides a means to fix the problem where tests produce unwanted output, such as errors or warnings. This can be confusing. We can instead set the console to silent and record this output. It can be checked later in the test if required. It is possible that this may prove useful for non-test situations. For example the console output may be suppressed for normal operations, but recorded and stored for access by the OS. That feature is not implemented at present. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-11-19input: Change LED state bits to conform i8042 compatible keyboardBin Meng
When sending LED update command to an i8042 compatible keyboard, bit1 is 'Num Lock' and bit2 is 'Caps Lock' in the data byte. But input library defines bit1 as 'Caps Lock' and bit2 as 'Num Lock'.
