| |
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.
We also add a separate patch for DT binding documentation of FU740 PRCI: https://patchwork.kernel.org/project/linux-riscv/patch/20201126030043.67390-1-zong.li@sifive.com/
Changed in v7: - Pick changes in v5 back up into this patch series.
Changed in v6: - Modify the patch "Add clock enable and disable ops" by Pragnesh. The changes as follows: - Remove spin lock in enable and disable functions - Call enable_bypass() before PLL output disable - Rebase code to Linux v5.10-rc7
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.
