From e01f242a8f78d733f1cc9e2e18633f21e0ad412f Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Sat, 2 Jul 2022 00:25:42 -0500 Subject: [PATCH] dt-bindings: i2c: mv64xxx: Add variants with offload support V536 and newer Allwinner SoCs contain an updated I2C controller which includes an offload engine for master mode. The controller retains the existing register interface, so the A31 compatible still applies. Add the V536 compatible and use it as a fallback for other SoCs with the updated hardware. This includes two SoCs that were already documented (H616 and A100) and two new SoCs (R329 and D1).
