7bff3c4ce4 ARM: DaVinci: evm sets up many devices
Update DaVinci EVM board setup to work with key drivers which are
now in mainline kernels:

 - I2C adapter (driver: i2c_davinci)
    * three gpio expanders (driver: pcf8574) used for
       - LEDs
       - audio codec control
       - misc device control (including USB VBUS, IDE-vs-CF)
    * at24 (driver: at24) eeprom
 - USB controller (driver: musb_hdrc)
 - IDE controller (driver: palm_bk3710)

This board is the first in-tree client for a number of those drivers,
and adding this board support means the EVM board can be used for some
"real work" ... excepting "DaVinci Technology" video and DSP support
(also available in most OMAP3 chips).

Also renames the flash as "evm_norflash", since NAND may be jumpered.

(Patch contains work by myself, Kevin Hilman, Sergei Shtylyov.)

dce1115bc3 ARM: DaVinci: SOC GPIOs use gpiolib
Switch DaVinci SOC gpios over to using the new GPIO library, so it can
access GPIO expanders and other non-SOC GPIOs using the same calls.

be50972935 [ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

18de5bc4c1 clockevents: fix resume logic
We need to make sure, that the clockevent devices are resumed, before
the tick is resumed. The current resume logic does not guarantee this.

Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock
event devices before resuming the tick / oneshot functionality.

Fixup the existing users.

Thanks to Nigel Cunningham for tracking down a long standing thinko,
which affected the jinxed VAIO.
