msm: board-8064: Increase LDO 25 voltage request from 1.225 V to 1.25 V
David Collins <collinsd@codeaurora.org>
Hardware characterization has shown that memory operates better
when its supply voltage (provided by LDO 25) is increased to
1.25 V. Therefore, increase the voltage constraints for LDO 25
so that 1.25 V is requested. This also requires modifying the
voltages requested by the consumers of LDO 25.

msm: 8064-regulator: Remove 5V FRC gpio external regulator
Jay Chokshi <jchokshi@codeaurora.org>
On MPQ-8064, 5V FRC regulator coordinates with FRC
reset signal in certain timing sequence, which is
controlled by FRC driver powerup sequence. The FRC driver
is implemented in Userspace.
Since kernel claims the same GPIO line to control as a
gpio voltage regulator, FRC Userspace driver fails to
handle it. Relinquish the control of the gpio line
as there are no kernel clients of the gpio anyways.

When v4l2 streamon() is called the framework moves to streamon state,

setting the state transisiton flag. This results in failure to dqbuf() as
the framework has not moved to streamon. This patch adds a mutex
around state transitions and dqbuf() calls.

This patch removes the need for the offset parameter in dma bounce
functions. This is required to let dma-mapping framework on ARM
architecture to use common, generic dma_map_ops based dma-mapping
helpers.
Background and more detailed explaination:
dma_*_range_* functions are available from the early days of the dma
mapping api. They are the correct way of doing a partial syncs on the
buffer (usually used by the network device drivers). This patch changes
only the internal implementation of the dma bounce functions to let
them tunnel through dma_map_ops structure. The driver api stays
unchanged, so driver are obliged to call dma_*_range_* functions to
keep code clean and easy to understand.
The only drawback from this patch is reduced detection of the dma api
abuse. Let us consider the following code:
dma_addr = dma_map_single(dev, ptr, 64, DMA_TO_DEVICE);
dma_sync_single_range_for_cpu(dev, dma_addr+16, 0, 32, DMA_TO_DEVICE);
Without the patch such code fails, because dma bounce code is unable
to find the bounce buffer for the given dma_address. After the patch
the above sync call will be equivalent to:
dma_sync_single_range_for_cpu(dev, dma_addr, 16, 32, DMA_TO_DEVICE);
which succeeds.
I don't consider this as a real problem, because DMA API abuse should be
caught by debug_dma_* function family. This patch lets us to simplify
the internal low-level implementation without chaning the driver visible
API.
