Subject: [PATCH v7 0/5] clk: add driver for the SiFive FU740
Date:   Wed,  9 Dec 2020 17:49:11 +0800

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.
