Add support for the graphics clock controller found on SM8150 based devices. This is initially copied from the downstream kernel, but has been modified to more closely match the upstream sc7180 driver.

Each of the CPU clusters (Power and Perf) on msm8996 are clocked via 2 PLLs, a primary and alternate. There are also 2 Mux'es, a primary and secondary all connected together as shown below +-------+ XO | | +------------------>0 | | | PLL/2 | SMUX +----+ +------->1 | | | | | | | +-------+ | +-------+ | +---->0 | | | | +---------------+ | +----------->1 | CPU clk |Primary PLL +----+ PLL_EARLY | | +------> | +------+-----------+ +------>2 PMUX | +---------------+ | | | | | +------+ | +-->3 | +--^+ ACD +-----+ | +-------+ +---------------+ +------+ | |Alt PLL | | | +---------------------------+ +---------------+ 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.

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. Signed-off-by: Taniya Das <tdas@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
