2020-07-10clk: qcom: Add CPU clock driver for msm8996Loic Poulain
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.

2017-12-13clk: qcom: fix 16 bit alpha support calculationAbhishek Sahu
The alpha value calculation has been written for 40-bit alpha values which doesn't work work properly for 16-bit ones. The alpha value is calculated on the basis of ALPHA_BITWIDTH to make the computation easy for 40 bit alpha. After calculating the 32 bit alpha, it is converted to 40 bit alpha by making lower bits zero. But if actual alpha register width is less than ALPHA_BITWIDTH, then the actual width can be used for calculation. This also means, during the 40 bit alpha pll set rate path, the lower alpha register is not configured Change the code to calculate the rate and register values from 'alpha_width' instead of hard-coding it so that it can work for the different widths that are supported.

Alpha PLL is a generic name used for QCOM PLLs which uses L and Alpha values for configuring the integer and fractional part. QCOM SoCs use different types of Alpha PLLs for which basic software configuration part is common with following differences. 1. All these PLLs have the same basic registers like PLL_MODE, L_VAL, ALPHA_VAL but some of the register offsets are different between PLLs types. 2. The dynamic programming sequence is different in some of the Alpha PLLs 3.

Some PLLs can support an HW FSM mode (different from the Votable FSMs, though its the same bit used to enable Votable FSMs as well as HW FSMs) which enables the HW to do the bypass/reset/enable-output-ctrl sequence on its own. So all thats needed from SW is to set the FSM_ENA bit. PLL_ACTIVE_FLAG is whats used to check if the PLL is active/enabled. Some of the PLLs which support HW FSM can also need an OFFLINE request that needs to be toggled across the enable/disable. We use a flag to identify such cases and handle them.
