18946f62c6 OMAP: DSS2: move update() and sync()
Move update() and sync() from omap_dss_device to omap_dss_driver.

Also, update was hardcoded to use virtual channel 0. This patch adds a
parameter that specifies the VC.

b9eb5d7d0b OMAP: DSS2: DSI: change DSI bus_lock to semaphore
Physical DSI bus is protected by a mutex. This patch changed the mutex to
a semaphore, so that we can lock and unlock the bus_lock from different
threads.

This is needed as the update process is started by user space program, and
thus the lock is acquired in that context, but the lock can be released in
different context, a work thread via irq.

dd8079d6a9 OMAP: DSS2: DSI: configure all DSI VCs
Instead of configuring only VC0 to be usable, configure all four VCs
similarly. This is needed to utilize the other VCs.

Setting the FIFO sizes evenly for all VCs, regardless of how many VCs are
actually used, is not optimal. However, this affects only cases when
larger amounts of data are written or read via L4, meaning that normal use
cases are not affected.

At some point this could be optimized better to suit different use cases.

2f18c4d898 OMAP: DSS2: improve DSS clk src selection
dss_select_clk_source() was rather confusing. Selecting the source with
enums is much clearer.

The clk source selection is also stored into memory, so that we know what
is the selected source, even when clocks are off. This is important during
setup, as we need to what clocks to turn on before the clocks are turned
on.

8a2cfea8cc OMAP: DSS2: enable VDDS_DSI when using DPI
It looks like on OMAP3 some DSS pins need VDDS_DSI to function properly.

This has not been confirmed from TI, but looking at figure 15-1 "Display
subsystem highlight" from the TRM, some data pins come near the DSI and SDI
blocks. This is not very hard evidence, but the fact remains that with the
power on, pixels are ok, and with the power off, pixels are not ok.

It may also be that VDDS_SDI is needed to power some pins, but as normally
both VDDS_SDI and VDDS_DSI come from the same power source, this hasn't
been shown.

It seems that a single driver can only get a regulator once. This patch
solves it by getting all the required regulators in one place, and from
which the submodules then get the regulators they need.
