2018-06-01clk: qcom: gcc-msm8996: Disable halt check on UFS clocksBjorn Andersson
The halt check of the UFS symbol clocks always fails, as such probing UFS after clk_disable_unused always fails. This makes it impossible to boot a system with the UFS phy or UFS HCD drivers compiled as modules. Follow SDM845 and disable the halt check on these clocks.

2018-06-01clk: msm8996-gcc: Mark halt check as no-op for USB/PCIE pipe_clkManu Gautam
The USB and PCIE pipe clocks are sourced from external clocks inside the QMP USB/PCIE PHYs. Enabling or disabling of PIPE RCG clocks is dependent on PHY initialization sequence hence update halt_check to BRANCH_HALT_SKIP for these clocks so that clock status bit is not polled when enabling or disabling the clocks. It allows to simplify PHY client driver code which is both user and source of the pipe_clk and avoid error logging related status check on clk_disable/enable.

2018-06-01clk: qcom: mmcc-msm8996: leave all mmagic gdscs and clocks always enabledRajendra Nayak
There's no bus infrastructure today to handle all the mmagic bus clocks and GDSCs needed by all the multimedia blocks in msm8996, like mdss, video, camera and gpu. Mark all these clocks with a CLK_IS_CRITICAL and GDSCs with a ALWAYS_ON flag for now so they are left always enabled. This patch should be reverted at some point when we do have a bus driver to manage these clocks and GDSCs.

2018-03-16clk: qcom: gcc-msm8996: Mark aggre0 noc clks as criticalSrinivas Kandagatla
aggre0 bus clks are not associated with any of the drivers, so its important that these clks are always on to get peripherals on this bus working. So mark them as critical. Eventually when we have a proper bus driver these clks can be marked appropriately. Without this patch pcie on db820c is not functional.

2017-12-13clk: qcom: support for alpha pll propertiesAbhishek Sahu
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 of the PLLs don’t have 64 bit config control, 64 bit user control, VCO configuration, etc. Signed-off-by: Abhishek Sahu <absahu@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2016-11-23clk: qcom: Move all sdcc rcgs to use clk_rcg2_floor_opsRajendra Nayak
The sdcc driver for msm8996/msm8916/msm8974/msm8994 and apq8084 expects a clk_set_rate() on the sdcc rcg clk to set a floor value of supported clk rate closest to the requested rate, by looking up the frequency table.
