efa2ca73a7 mtd: Add DiskOnChip G3 support
Add support for DiskOnChip G3 chips. The support is quite
limited yet :
 - no flash writes/erases are implemented
 - ECC fixes are not implemented
 - powerdown is not implemented
 - IPL handling is not yet done

On the brighter side, the chip reading does work.

96cd895168 ftmac100: fix skb truesize underestimation
ftmac100 allocates a page per skb fragment. We must account

bf164c58e5 hwmon: (w83627ehf) Properly report thermal diode sensors
The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".

Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.

839e7306e5 IDE: Don't powerdown Compaq Triflex IDE device on suspend
Don't powerdown Compaq Triflex IDE device on suspend

This fixes APM suspend on Compaq Armada 7400.
APM BIOS doesn't suspend if IDE is powered down when suspending.
The Triflex controller is found only on old Compaq boards,
so this patch will hopefully have no side effects.

This patch fixes a suspend regression introduced in
feb22b7f8e ("ide: add proper PCI PM
support (v2)").

78a4315872 gpio/omap: fix build error with certain OMAP1 configs
With commit f64ad1a0e2, "gpio/omap: cleanup _set_gpio_wakeup(), remove
ifdefs", access to build time conditionally omitted 'suspend_wakeup'
member of the 'gpio_bank' structure has been placed unconditionally in
function _set_gpio_wakeup(), which is always built. This resulted in the
driver compilation broken for certain OMAP1, i.e., non-OMAP16xx,
configurations.

Really required or not in previously excluded cases, define this
structure member unconditionally as a fix.

Tested with a custom OMAP1510 only configuration.

This patch do the following things:

1. Add header and Copyright for marvell usb driver.
2. Add mv_usb.h in include/linux/platform_data, make the driver
   fits all the marvell platform using the same ChipIdea usb ip.
3. Some SOC may has mutiple clock sources, so let me define it
   in mv_usb_platform_data and give two helper functions named
   udc_clock_enable/udc_clock_disable to deal with the clocks.
4. Different SOCs will have some difference in PHY initialization,
   so we will remove file mv_udc_phy.c and add two funtions in
   mv_usb_platform_data, let the platform relative driver to realize it.
5. Rewrite probe function according to the modification list above. Find
   it will kernel panic when probe failed. The root cause is as follows:
	When probe failed, the error handle may call device_unregister()
	which in return will call gadget_release.In current code,
	gadget_release have two issues:
		1: the_controller is a NULL pointer.
		2: if we free udc here, then the following code in probe
		   will access NULL pointer.
