Subject: arm64: dts: allwinner: h616: add NAND controller
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f55a2526317aca8ecc1b21b346dbdebbc6aad97d;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: allwinner: h616: add NAND controller

The H616 has a NAND controller quite similar to the A10/A23 ones, but
with some register differences, more clocks (for ECC and MBUS), more ECC
strengths, so this requires a new compatible string.

Add the NAND controller node and pins in the device tree.
