We duplicate the 'depends on' in almost every Kconfig here, and it's
getting out of hand now that we have tens of options for various SoC
drivers here. Let's clean it up a little by making a menuconfig for a
submenu and adding an if wrapper around the driver section.

Add support for the lpass clock controller found on SDM845 based devices.
This would allow lpass peripheral loader drivers to control the clocks to

LPASS clocks present on the global clock controller would be registered
with the clock framework based on the protected-clock flag. Also do not
gate these clocks if they are left unused, as the lpass clocks require
the global clock controller lpass clocks to be enabled before they are
accessed. Mark the GCC lpass clocks as CRITICAL, for the LPASS clock
access.

81ac38847a clk: qcom: Add APCS clock controller support
Add a driver for the APCS clock controller. It is part of the APCS
hardware block, which among other things implements also a combined
mux and half integer divider functionality. It can choose between a
fixed-rate clock or the dedicated APCS (A53) PLL. The source and the
divider can be set both at the same time.

This is required for enabling CPU frequency scaling on MSM8916-based
platforms.

0c6ab1b8f8 clk: qcom: Add A53 PLL support
The CPUs on Qualcomm MSM8916-based platforms are clocked by two PLLs,
a primary (A53) CPU PLL and a secondary fixed-rate GPLL0. These sources
are connected to a mux and half-integer divider, which is feeding the
CPU cores.

This patch adds support for the primary CPU PLL which generates the
higher range of frequencies above 1GHz.

This adds initial support for clocks controlled by the Resource
Power Manager (RPM) processor on some Qualcomm SoCs, which use
the qcom_smd_rpm driver to communicate with RPM.
Such platforms are msm8916, apq8084 and msm8974.

The RPM is a dedicated hardware engine for managing the shared
SoC resources in order to keep the lowest power profile. It
communicates with other hardware subsystems via shared memory
and accepts clock requests, aggregates the requests and turns
the clocks on/off or scales them on demand.

This driver is based on the codeaurora.org driver:
