Add support for configuring the CLK_25M pin as well as the RGMII I/O voltage by the device tree. By default the AT803x PHYs outputs the 25MHz clock of the XTAL input. But this output can also be changed by software to other frequencies. This commit introduces a generic way to configure this output. Also the PHY supports different RGMII I/O voltages: 1.5V, 1.8V and 2.5V. An internal LDO is able to provide 1.5V (default) and 1.8V. The 2.5V option needs an external supply voltage. This commit adds support to switch the internal LDO to 1.8V. Signed-off-by: Michael Walle <michael@walle.cc> Acked-by: Joe Hershberger <joe.hershberger@ni.com> |

Device Tree Bindings Staging Area ================================= This directory contains device tree bindings for U-Boot. These follow along with Linux kernel bindings, with a few additions. By adding the files here, U-Boot patches can clearly show thees additions. This makes it easier for device tree people to review these additions in patches sent to the U-Boot mailing list. The intent IS to commit these files to U-Boot. Hopefully at some point the files will be stored in another repo (shared with Linux) which is brought in as needed. Changes here are intended to mirror changes in the Linux Documentation/devicetree/bindings/ directory. sjg@chromium.org 17-Jan-12
