Add a driver for the SiFive FU740 PRCI IP block, which handles more
clocks than FU540. These patches also refactor the original
implementation by spliting the dependent-code of fu540 and fu740
respectively. In v3 and v4 patch set, it fix the wrong clk enable bit
field which reported by Pragnesh.
We also add a separate patch for DT binding documentation of FU740 PRCI:
https://patchwork.kernel.org/project/linux-riscv/patch/20...
Changed in v5:
- Fix copyright format
- Add a link of documentation in commit message
- Modify build dependency for sifive-prci.c
- Add enable and disable functions by Pragnesh Patel
Changed in v4:
- Fix the wrong enable bit field shift for FU540 and FU740.
Changed in v3:
- Fix the wrong enable bit field shift for FU740.
Changed in v2:
- Remove the macro definition for __prci_clock_array.
- Indicate the functional changes in commit message.
- Using option -M and -C to create patches.
- Rebase code to kernel v5.10-rc3.
