8bcde6582c clk: qcom: rpmcc: Add support to XO buffered clocks
XO is onchip buffer clock to generate 19.2MHz.

This patch adds support to 5 XO buffer clocks found on PMIC8921,
these buffer clocks can be controlled from external pin or in
manual mode.

d4a69583de clk: qcom: Implement RPM clocks for MSM8660/APQ8060
The RPM clocks were missing for MSM8660/APQ8060. For this to be
completed we need to add a special fixed rate RPM clock that is used
for the PLL4 on these SoCs. The rest of the clocks are pretty
similar to the other supported platforms.

The "active" clock pattern is mirrored in all the clocks. I guess
that the PLL4 that clocks the LPASS is actually never used as
"active only" since the low-power audio subsystem should be left
on when the CPU goes to idle, so that it can be used as a stand-alone
MP3 player type of device.

The PLL4 seems to be enabled only on behalf of the booting LPASS
Hexagon - which will cast its own vote once its booted - and as
such we only configure the active state (meaning both states will
have same configuration). The result is that PLL4 will be on
from prepare() to unprepare() regardless of what the application
CPU does.

c260524aba clk: qcom: clk-rpm: Fix clk_hw references
Fix the clk_hw references to the actual clocks and add a xlate function
to return the hw pointers from the already existing static array.

872f91b5ea clk: qcom: Add support for RPM Clocks
This adds initial support for clocks controlled by the Resource
Power Manager (RPM) processor on some Qualcomm SoCs, which use
the qcom_rpm driver to communicate with RPM.
Such platforms are apq8064 and msm8960.
