Merge tag 'davinci-for-v3.10/dt' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/soc

From Sekhar Nori <nsekhar@ti.com>:

v3.10 DT updates for DaVinci

The pull request adds support for MMC/SD and regulator on DA850 EVM.

* tag 'davinci-for-v3.10/dt' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci

:
  ARM: davinci: da850: override mmc DT node device name
  ARM: davinci: da850: add mmc DT entries
  mmc: davinci_mmc: add DT support
  ARM: davinci: da850: add tps6507x regulator DT data
  ARM: regulator: add tps6507x device tree data

Merged into soc branch rather than DT branch to avoid circular dependencies.

* TI Highspeed MMC host controller for DaVinci



The Highspeed MMC Host Controller on TI DaVinci family

provides an interface for MMC, SD and SDIO types of memory cards.



This file documents the properties used by the davinci_mmc driver.



Required properties:

- compatible:

 Should be "ti,da830-mmc": for da830, da850, dm365

 Should be "ti,dm355-mmc": for dm355, dm644x



Optional properties:

- bus-width: Number of data lines, can be <1>, <4>, or <8>, default <1>

- max-frequency: Maximum operating clock frequency, default 25MHz.

- dmas: List of DMA specifiers with the controller specific format

	as described in the generic DMA client binding. A tx and rx

	specifier is required.

- dma-names: RX and TX  DMA request names. These strings correspond

	1:1 with the DMA specifiers listed in dmas.



Example:

mmc0: mmc@1c40000 {

	compatible = "ti,da830-mmc",

	reg = <0x40000 0x1000>;

	interrupts = <16>;

	status = "okay";

	bus-width = <4>;

	max-frequency = <50000000>;

	dmas = <&edma 16

		&edma 17>;

	dma-names = "rx", "tx";

};
