| | | | * | | clk: qcom: Add MSM8998 GPU Clock Controller (GPUCC) driverJeffrey Hugo2019-11-073-0/+348

| | | | * | | clk: qcom: Allow constant ratio freq tables for rcgJeffrey Hugo2019-11-072-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some RCGs (the gfx_3d_src_clk in msm8998 for example) are basically just some constant ratio from the input across the entire frequency range. It would be great if we could specify the frequency table as a single entry constant ratio instead of a long list, ie: { .src = P_GPUPLL0_OUT_EVEN, .pre_div = 3 }, { } So, lets support that. We need to fix a corner case in qcom_find_freq() where if the freq table is non-null, but has no frequencies, we end up returning an "entry" before the table array, which is bad. Then, we need ignore the freq from the table, and instead base everything on the requested freq.

| | | | * | | clk: qcom: smd: Add missing pnoc clockJeffrey Hugo2019-11-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When MSM8998 support was added, and analysis was done to determine what clocks would be consumed. That analysis had a flaw, which caused the pnoc to be skipped. The pnoc clock needs to be on to access the uart for the console. The clock is on from boot, but has no consumer votes in the RPM. When we attempt to boot the modem, it causes the RPM to turn off pnoc, which kills our access to the console and causes CPU hangs. We need pnoc to be defined, so that clk_smd_rpm_handoff() will put in an implicit vote for linux and prevent issues when booting modem. Hopefully pnoc can be consumed by the interconnect framework in future so that Linux can rely on explicit votes.

| | * | | clk: ti: divider: convert to use min,max,mask instead of widthTero Kristo2019-10-312-91/+74

For example, if max divider value is 4, the smallest all-1 bitmask that can hold this value is 7, which allows values higher than 4 to be used. This typically causes unpredictable results with hardware. So far this issue hasn't been noticed as most of the dividers actually have maximum values which fit the whole bitfield, but there are certain clocks for which this is a problem, like dpll4_m4 divider on omap3 devices. Thus, convert the whole validity logic to use min,max and mask values for determining if a specific divider is valid or not. This prevents the odd cases where bad value would otherwise be written to a divider config register. Signed-off-by: Tero Kristo <t-kristo@ti.com> Tested-by: Adam Ford <aford173@gmail.com>
