2023-09-13clk: qcom: gcc-sm8250: Fix gcc_sdcc2_apps_clk_srcPatrick Whewell1-0/+1
[ Upstream commit 783cb693828ce487cf0bc6ad16cbcf2caae6f8d9 ] GPLL9 is not on by default, which causes a "gcc_sdcc2_apps_clk_src: rcg didn't update its configuration" error when booting. Set .flags = CLK_OPS_PARENT_ENABLE to fix the error.

2022-12-31clk: qcom: gcc-sm8250: Use retention mode for USB GDSCsManivannan Sadhasivam1-2/+2
[ Upstream commit ac1c5a03d3772b1db25e8092f771aa33f6ae2f7e ] USB controllers on SM8250 doesn't work after coming back from suspend. This can be fixed by keeping the USB GDSCs in retention mode so that hardware can keep them ON and put into rentention mode once the parent domain goes to a low power state.

2021-04-08clk: qcom: gcc-sm8250: use ARRAY_SIZE instead of specifying num_parentsDmitry Baryshkov1-46/+46
Use ARRAY_SIZE() instead of manually specifying num_parents. This makes adding/removing entries to/from parent_data easy and errorproof.

2021-04-08clk: qcom: gcc-sm8250: use parent_hws where possibleDmitry Baryshkov1-126/+126
Switch to using parent_hws instead of parent_data when parents are defined in this driver and so accessible using clk_hw.
