From b85a3ef4ac65169b65fd2fe9bec7912bbf475ba4 Mon Sep 17 00:00:00 2001 From: John Linn Date: Mon, 20 Jun 2011 11:47:27 -0600 Subject: ARM: Xilinx: Adding Xilinx board support The 1st board support is minimal to get a system up and running on the Xilinx platform. This platform reuses the clock implementation from plat-versatile, and it depends entirely on CONFIG_OF support. There is only one board support file which obtains all device information from a device tree dtb file which is passed to the kernel at boot time.

It contains several audio analog inputs and outputs as well as vibrator support. It's connected to the host processor via PDM interface for audio data communication. The audio modules are controlled by internal registers that can be accessed by I2C and PDM interface. TWL6040 MFD will be registered as a child of TWL-CORE, and will have two children of its own: twl6040-codec and twl6040-vibra. This driver is based on TWL4030 and WM8350 MFD drivers.

Since there the product has shipped and there won't be any bootloader updates to fix this issue, we need to define all the regulators and declare full constraints for the regulator FW. This will allow the regulator FW to disable unused regulators. Also this helps in adding more fine grain regulator support for rx-51 in the future.
