This patchset adds the clock & reset driver support for i.MX8ULP. For some of the PCC slot, As there is a SWRST control bit share the same pcc register for peripheral reset ccontrol. To simplify the case, register the pcc reset controller driver when pcc clock driver is registered. Patch 1/9 for the dt-bindings part is send out for review previously with the dts patchset: https://patchwork.kernel.org/project/linux-arm-kernel/cover/20210607083921.2668568-1-ping.bai@xxxxxxx/ Shawn suggests to send out the clock driver part firstly, so this patch is included in this patchset for now. v3 changes: - split the clock dt schema file into two file, one for pcc, one for cgc v2 changes: - remove the useless clocks & clock-names from the dt-binding doc - remove the redundant fixed clock register.
