Subject: [PATCH 1/2] dt-bindings: mmc: sunxi: Add D1 MMC and eMMC compatibles
Date: Wed, 2 Feb 2022 19:51:10 -0600 [thread overview]
Message-ID: <20220203015112.12008-1-samuel@sholland.org> (raw)
D1 contains variants of the usual sunxi MMC controller. The eMMC
controller has the same parameters as the A100 eMMC controller. The
other controllers have a DMA address shift like on A100, but they have
a smaller 13-bit size field, making them a new incompatible variant.
