The MFG_BG3D is a gate to enable/disable clock output to the GPU, but the actual output is decided by multiple muxes; in particular: mfg_ck_fast_ref muxes between "slow" (top_mfg_core_tmp) and "fast" (MFGPLL) clock, while top_mfg_core_tmp muxes between the 26MHz clock and various system PLLs. The clock gate comes after all the muxes, so its parent is mfg_ck_fast_reg, not top_mfg_core_tmp. Reparent MFG_BG3D to the latter to match the hardware and add the CLK_SET_RATE_PARENT flag to it: this way we ensure propagating rate changes that are requested on MFG_BG3D along its entire clock tree.

2022-09-29clk: mediatek: mt8183: Add clk mux notifier for MFG muxChen-Yu Tsai1-0/+28
When the MFG PLL clock, which is upstream of the MFG clock, is changed, the downstream clock and consumers need to be switched away from the PLL over to a stable clock to avoid glitches. This is done through the use of the newly added clk mux notifier. The notifier is set on the mux itself instead of the upstream PLL, but in practice this works, as the rate change notifitcations are propogated throughout the sub-tree hanging off the PLL. Just before rate changes, the MFG mux is temporarily and transparently switched to the 26 MHz main crystal. After the rate change, the mux is switched back.

2022-09-29clk: mediatek: mux: add clk notifier functionsChen-Yu Tsai2-0/+53
With device frequency scaling, the mux clock that (indirectly) feeds the device selects between a dedicated PLL, and some other stable clocks. When a clk rate change is requested, the (normally) upstream PLL is reconfigured. It's possible for the clock output of the PLL to become unstable during this process. To avoid causing the device to glitch, the mux should temporarily be switched over to another "stable" clock during the PLL rate change. This is done with clk notifiers.

2022-09-28clk: pistachio: Fix initconst confusionAndi Kleen1-2/+2
A variable pointing to const isn't const itself. It has to contain "const" keyword after "*" too. So to keep it in __initconst (and not mark properly as __initdata), add the "const" keyword exactly there. Note we need to update struct pistachio_mux too. On the other hand, the clk core already counts with "const char *const" already. [js] more explanatory commit message.

2022-09-27clk: qcom: gcc-sc7280: Update the .pwrsts for usb gdscsRajendra Nayak1-2/+2
The USB controllers on sc7280 do not retain the state when the system goes into low power state and the GDSCs are turned off. This results in the controllers reinitializing and re-enumerating all the connected devices (resulting in additional delay while coming out of suspend) Fix this by updating the .pwrsts for the USB GDSCs so they only transition to retention state in low power. Since sc7280 only supports cx (parent of usb gdscs) Retention, there are no cxcs offsets mentioned in order to support the Retention state.

2022-09-27clk: qcom: gdsc: Fix the handling of PWRSTS_RET supportRajendra Nayak2-0/+15
GDSCs cannot be transitioned into a Retention state in SW. When either the RETAIN_MEM bit, or both the RETAIN_MEM and RETAIN_PERIPH bits are set, and the GDSC is left ON, the HW takes care of retaining the memory/logic for the domain when the parent domain transitions to power collapse/power off state. On some platforms where the parent domains lowest power state itself is Retention, just leaving the GDSC in ON (without any RETAIN_MEM/RETAIN_PERIPH bits being set) will also transition it to Retention. The existing logic handling the PWRSTS_RET seems to set the RETAIN_MEM/RETAIN_PERIPH bits if the cxcs offsets are specified but then explicitly turns the GDSC OFF as part of _gdsc_disable(). Fix that by leaving the GDSC in ON state.
