Merge tag 'sunxi-clk-for-5.20-1' of... 

Merge tag 'sunxi-clk-for-5.20-1' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into clk-allwinner

Pull Allwinner clk driver updates from Jernej Skrabec:

 - deduplicate Allwinner ccu_clks arrays
 - Allwinner H6 GPU DFS support
 - adjust Allwinner Kconfig

* tag 'sunxi-clk-for-5.20-1' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux:
  clk: sunxi-ng: sun50i: h6: Modify GPU clock configuration to support DFS
  clk: sunxi: Do not select the PRCM MFD
  clk: sunxi: Limit legacy clocks to 32-bit ARM
  clk: sunxi-ng: Deduplicate ccu_clks arrays
