* cros-ec-keyboard: Synchronize DT binding from linuxSjoerd Simons2015-01-05-30/+23
| | | | | | | | | | | | | | | | | | The ChromeOS EC keyboard is used by various different chromebooks. Peach pi being the third board in the u-boot tree to use it (snow and peach pit the other two). Rather then embedding the same big DT node in the peach-pi DT again, copy the dtsi snippit & bindings documentation from linux and include it in all 3 boards. This slightly changes the dt bindings in u-boot: * google,key-rows becomes keypad,num-rows * google,key-colums becomes keypad,num-colums * google,repeat-delay-ms and google,repeat-rate-ms are no longer used and replaced by hardcoded values (similar to tegra kbc) Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>

Support includes hooking into the pmic infrastructure so that the pmic commands can be used on the console. The TPS65090 supports the following functionality: - fet enable/disable/querying - getting and setting of charge state Even though it is connected to the pmic infrastructure it does not hook into the pmic charging charging infrastructure. The device tree binding is from Linux, but only a small subset of functionality is supported.

* | lcd: add functions to set up simplefb device treeStephen Warren2013-06-05-0/+25
|/ | | | | | | | | | | | | | | | simple-framebuffer is a new device tree binding that describes a pre- configured frame-buffer memory region and its format. The Linux kernel contains a driver that supports this binding. Implement functions to create a DT node (or fill in an existing node) with parameters that describe the framebuffer format that U-Boot is using. This will be immediately used by the Raspberry Pi board in U-Boot, and likely will be used by the Samsung ARM ChromeBook support soon too. It could well be used by many other boards (e.g. Tegra boards with built-in LCD panels, which aren't yet supported by the Linux kernel).
