8f62718bd0 clk: qcom: Add MSM8976/56 Global Clock Controller (GCC) driver
Add support for the global clock controller found on MSM8956
and MSM8976 SoCs.
Since the multimedia clocks are actually in the GCC on these
SoCs, this will allow drivers to probe and control basically
all the required clocks.

Add Global Clock Controller (GCC) driver for QCM2290.  This is a porting
of gcc-scuba driver from CAF msm-4.19, with GDSC support added on top.

Because the alpha_pll on the platform has a different register
layout (offsets), its own clk_alpha_pll_regs_offset[] is used in the
driver.

+---------------+         PLL_EARLY

The primary PLL is what drives the CPU clk, except for times
when we are reprogramming the PLL itself (for rate changes) when
we temporarily switch to an alternate PLL. A subsequent patch adds
support to switch between primary and alternate PLL during rate
changes.

The primary PLL operates on a single VCO range, between 600MHz
and 3GHz. However the CPUs do support OPPs with frequencies
between 300MHz and 600MHz. In order to support running the CPUs
at those frequencies we end up having to lock the PLL at twice
the rate and drive the CPU clk via the PLL/2 output and SMUX.

So for frequencies above 600MHz we follow the following path
 Primary PLL --> PLL_EARLY --> PMUX(1) --> CPU clk
and for frequencies between 300MHz and 600MHz we follow
 Primary PLL --> PLL/2 --> SMUX(1) --> PMUX(0) --> CPU clk

ACD stands for Adaptive Clock Distribution and is used to
detect voltage droops.

1664014e46 clk: qcom: gcc-msm8939: Add MSM8939 Generic Clock Controller
This patch adds support for the MSM8939 GCC. The MSM8939 is based on the
MSM8916. MSM8939 is compatible in several ways with MSM8916 but, has
additional functional blocks added which require additional PLL sources. In
some cases functional blocks from the MSM8916 have different clock sources
or different supported frequencies.

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