Subject: dt-bindings: dma: mediatek,uart-dma: Support all SoC generations
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fd7843f0da58b37072c1dafa779d128bb36912bf;p=thirdparty%2Flinux.git

dt-bindings: dma: mediatek,uart-dma: Support all SoC generations

Add support for the APDMA IP found in all of the SoC generations
that are currently supported upstream; this includes:
 - MT8173, MT8183, fully compatible with MT6577 (32-bits)
 - MT7988, MT8186, MT8188, MT8192, MT8195 and MT6835 (34-bits)
 - MT6991, MT8196 and MT6985 (35-bits)

...where:
 - MT6835 is the first SoC where the AP_DMA IP supports 34-bits
   addressing; and
 - MT6985 is the first SoC where the AP_DMA IP supports 35-bits
   addressing.

While at it, also add myself in the maintainers list.
