clk: qcom: Add CPU clock driver for msm8996

2020-07-11T00:09:20+00:00

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.

clk: qcom: gcc-msm8939: Add MSM8939 Generic Clock Controller

2020-05-27T02:37:58+00:00

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.
