Wei Yongjun 13b47d5f79 staging: sep: fix possible memory leak in sep_prepare_input_dma_table()
'lli_array_ptr' etc. are malloced in sep_prepare_input_dma_table() and should
be freed before leaving from the error handling case, otherwise it will cause
memory leak.

Eduardo Valentin ff4a44ce32 staging: omap-thermal: remove TODO entry for exposed APIs
Not all APIs exposed today are used. However all unused APIs
will be required once the thermal layer allows IRQ based
policies.

Eduardo Valentin 0205b15fa4 staging: omap-thermal: remove TODO entry suggesting regmap usage
It is hard to use regmap because benefit of using regmap cache
may not be applicable as there is a specific sequence to
restore the bandgap context.

Eduardo Valentin ebf0bd52e6 staging: omap-thermal: switch mutex to spinlock inside omap-bandgap
Because there is a need to lock inside IRQ handler, this patch
changes the locking mechanism inside the omap-bandgap.[c,h] to
spinlocks. Now this lock is used to protect omap_bandgap struct
during APIs exposed (possibly used in sysfs handling functions)
and inside the ALERT IRQ handler.

Because there are registers shared among the sensors, this lock
is global, not per sensor.

Eduardo Valentin 494bbdd8b1 staging: omap-thermal: change Kconfig dependency method
Now arch code has to specify CONFIG_ARCH_HAS_BANDGAP. So, this driver
will be selectable only if the platform reports itself as having a
bandgap device.

Any OMAP variant or any other OMAP version needs to
	select ARCH_HAS_BANDGAP
so that the driver will be applicable. A part from that it is
required to device the data structures that maps the registers
and their bitfields. The DT compatible list must also be updated.

Eduardo Valentin 56f132f78e staging: omap-thermal: refactor APIs handling threshold values
This patch improves the code that handles threshold values
by creating single functions that are usable for tcold and
thot. This way we won't have duplicated functionality just
because it is handling different bitfields. Now
the added functions are reused in several places where
it is needed to update any threshold.

This patch also removes macros that are used only inside
the _validate helper function.

In this patch there is also an addition of an extra function
section for Exposed APIs, used outside the omap-bandgap.c,
but inside the omap-thermal driver.
