the mmci driver (drivers/mmc/host/mmci.c) does the following sequence:
* clk_prepare_enable()
* clk_set_rate()
on SDCx_clk which is a children of SDCx_src. SDCx_src has
CLK_SET_RATE_GATE so this sequence should not be allowed but this was not
enforced. IOW, the flag is ignored. Dropping the flag won't change
anything to the current behaviour of the platform.
CLK_SET_RATE_GATE is being fixed and enforced now. If the flag was kept,
the mmci driver would receive -EBUSY when calling clk_set_rate()

The offset seems to have been copied from the sata clk. Fix it so
that enabling the crypto engine source clk works.

This reverts commit 329cabcecf94d8d7821e729dda284ba9dec44c87.
The commit that caused us to specify LE device endianness here,
29bb45f25ff3 (regmap-mmio: Use native endianness for read/write,
2015-10-29), has been reverted in mainline so now when we specify
LE it actively breaks big endian kernels because the byte
swapping in regmap-mmio is incorrect. Let's revert this change
because it will 1) fix the big endian kernels and 2) be redundant
to specify LE because that will become the default soon.

All these clock controllers are little endian devices, but so far
we've been relying on the regmap mmio bus handling this for us
without explicitly stating that fact. After commit 4a98da2164cf
(regmap-mmio: Use native endianness for read/write, 2015-10-29),
the regmap mmio bus will read/write with the __raw_*() IO
accessors, instead of using the readl/writel() APIs that do
proper byte swapping for little endian devices.
So if we're running on a big endian processor and haven't
specified the endianness explicitly in the regmap config or in
DT, we're going to switch from doing little endian byte swapping
to big endian accesses without byte swapping, leading to some
confusing results. On my apq8074 dragonboard, this causes the
device to fail to boot as we access the clock controller with
big endian IO accesses even though the device is little endian.
Specify the endianness explicitly so that the regmap core
properly byte swaps the accesses for us.

Put these clocks into the dt files instead of registering them
from C code. This provides a few benefits. It allows us to
specify the frequency of these clocks at the board level instead
of hard-coding them in the driver. It allows us to insert an RPM
clock in between the consumers of the crystals and the actual
clock. And finally, it helps us transition the GCC driver to use
RPM clocks when that configuration is enabled.

8960 family of devices have TSENS as part of GCC in hardware.
Hence DT would represent a GCC node with GCC properties as well
as TSENS. Create a virtual platform child device here for TSENS
so the driver can probe it and use the parent (GCC) to extract DT
properties.

In the current parent mapping code, we can get duplicate or inconsistent
indexes, which leads to discrepancy between the number of elements in the
array and the number of parents. Until now, this was solved with some
reordering but this is not always possible.
This patch introduces index tables that are used to define the relations
between the PLL source and the hardware mux configuration value.
To accomplish this, here we do the following:
- Define a parent_map struct to map the relations between PLL source index
and register configuration value.
- Add a qcom_find_src_index() function for finding the index of a clock
matching the specific PLL configuration.
- Update the {set,get}_parent RCG functions use the newly introduced
parent_map struct.
- Convert all existing drivers to the new parent_map tables.

The APQ8064 and MSM8960 share a significant amount of clock data and
code between the two SoCs. Rather than duplicating the data we just add
support for a unqiue APQ8064 clock table into the MSM8960 code.
For now add just enough clocks to get a basic serial port going on an
APQ8064 device.
