This patch corrects the vendor-prefix for isl29028 in the compatible property from
"isil,isl29028" to "isl,isl29028" according to listed vendor-prefixes in
Documentation/devicetree/bindings/vendor-prefixes.txt. Incorrect vendor-prefix "isl"
was reported by checkpatch.pl warning for drivers/staging/iio/light/isl29028.c.
Thus incorrect vendor-prefix "isil" was corrected for every mention of device isl29028.

According to the Atmel eXtended DMA controller datasheet, requesting a
DMA transfer flush for a channel is only revelant when this transfer is
source peripheral synchronized.
So we have to check this condition before requesting a channel flush by
writing the channel bit into the Global channel SoftWare Flush (GSWF)
register then waiting for flush to complete by monitoring the end of
Flush Interrupt Status (FIS) bit in the Channel Interrupt Status (CIS)
register.
Indeed, for non source peripheral synchronized transfer, writing the
channel bit into the GSWF register does nothing. Especially, the FIS bit
is never set into the CIS register. The former code looped forever
waiting for this bit to be set.

Just add basic support for the moment, the following updates are needed:
i) Ethernet - depends on SoC dts fixes
ii) USB Client (USB2) - depends on GPIO extcon
ii) HDMI - additional driver fixes pending
iii) Audio - additional driver fixes pending
NOTE:
AM5728 Data Manual (SPRS915L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions". This implies
that all unused voltage rails for AM5728 can never be switched off even
if the hardware blocks inside that voltage domain is unused. Switching
off these unused rails may result in stability issues on other domains
and increased leakage and power-on-hour impacts.

We can't suppose that the i2c2 pins are configured as I2C bus, these pins are
connected to expansion connectors.

Add support for the new hardware revision of the IGEPv2. Basically, the new
revision F replaces the old Wifi module for a Wilink8 based module.

Use the omap3-igep0020-common.dtsi file and remove repeated parts leaving
the nodes that are not common between IGEPv2 hardware revisions.
