From b01065eee432b3ae91a2c0aaab66c2cae2e9812d Mon Sep 17 00:00:00 2001 From: Yong Wu Date: Tue, 14 Sep 2021 19:36:51 +0800 Subject: [PATCH] dt-bindings: memory: mediatek: Add mt8195 smi binding Add mt8195 smi supporting in the bindings. In mt8195, there are two smi-common HW, one is for vdo(video output), the other is for vpp(video processing pipe). They connect with different smi-larbs, then some setting(bus_sel) is different. Differentiate them with the compatible string. Something like this: IOMMU(VDO) IOMMU(VPP) | | SMI_COMMON_VDO SMI_COMMON_VPP ---------------- ---------------- | | ... | | ... larb0 larb2 ... larb1 larb3 ...
