[U-Boot] [PATCH 1/3] pmic: dialog: Avoid name conflicts

[U-Boot] [PATCH 1/3] pmic: dialog: Avoid name conflicts

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

As mx53loco board has two variants: one with Dialog PMIC and another with FSL MC34708 PMIC,
we need to be able to build both drivers.

Change pmic_init() and PMIC_NUM_OF_REGS names to avoid build conflicts when both drivers are present.

[U-Boot] [PATCH 3/4] mx53loco: Turn on VUSB regulator

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

On the mx53loco board with mc34708 PMIC it is necessary to turn on VUSB regulator
so that the mx53 USBH1 PHY receives the 3.3V voltage.

Tested by inserting a USB pen drive in the upper USB slot (USBH1) and then issued the
commands:

usb start

usb info

,which correctly detected and printed the USB pen drive information.

[U-Boot] [PATCH 4/4] mx53loco: Add CONFIG_REVISION_TAG

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information.

The kernel uses this data to distinguish between Dialog versus mc34708 based boards,
and also to distinguish between revA and revB of the mc34708 based boards.
