[PATCH v2 1/6] clk: sunxi: Add NAND clocks and resets

Samuel Holland samuel at sholland.org
Sun Jan 22 23:06:31 CET 2023


Currently NAND clock setup is done in board code, both in SPL and in
U-Boot proper. Add the NAND clocks/resets here so they can be used by
the "full" NAND driver once it is converted to the driver model.

The bit locations are copied from the Linux CCU drivers.

Changes in v2:
 - Fix A80 bus clock/reset bit positions
