Hema HK ee896e348c usb: otg: OMAP4430: Introducing suspend function for power management
Introduced the suspend/resume function for the OMAP4430 internal PHY.
This will be used by the twl6030-usb transceiver driver.
Moved the clock enable/disable function calls and power on/off of the PHY
code from power on/off functions to suspend/resume function.

Pass the suspend function through board data for OMAP4430sdp and OMAP4panda.
This will be used by the twl6030-usb transceiver driver.

Moved all the board specific internal PHY functions out of usb_musb.c file
as this file is shared between the OMAP2+ and AM35xx platforms.
There exists a file which has the functions specific to internal PHY
used for OMAP4 platform. Moved all phy specific functions to this file
and passing these functions through board data in the board file.

Hema HK c33fad0c37 usb: otg: Adding twl6030-usb transceiver driver for OMAP4430
Adding the twl6030-usb transceiver support for OMAP4 musb driver.

OMAP4 supports 2 types of transceiver interface.

1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality
is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin
sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY
functionality is embedded within the OMAP4430.

There is no direct interactions between the MUSB controller and TWL6030
chip to communicate the session-valid, session-end and ID-GND events.
It has to be done through a software by setting/resetting bits in
one of the control module register of OMAP4430 which in turn toggles
the appropriate signals to MUSB controller.

The internal transceiver has functional clocks and
powerdown bits to powerdown the PHY for power saving.

Since there is no option available for having 2 transceiver drivers
for one USB controller, internal PHY specific APIs are passed through
plaform_data function pointers to use in the twl6030-usb transceiver
driver.

2. ULPI interface is provided for off-chip transceivers.

Felipe Balbi 6f69a1815a omap2/3/4: ehci: avoid compiler error with touchbook
the early_param() call in board-omap3touchbook.c expands to:

static const char __setup_str_early_touchbook_revision[]
	__section(.init.rodata) _aligned(1) = tbr;
[...]

and we have a non-const variable being added to the
same section:

static struct ehci_hcd_omap_platform_data ehci_pdata
__section(.init.rodata);

because of that, gcc generates a section type conflict
which can (and actually should) be avoided by marking
const every variable marked with __initconst.

This patch fixes that for the ehci_hdc_omap_platform_data.
