From 79da1a96c21819a8e0f6b82b62b66325d05dc7d4 Mon Sep 17 00:00:00 2001 From: Hai Pham Date: Tue, 28 Feb 2023 22:25:51 +0100 Subject: [PATCH] i2c: rcar_i2c: Add R-Car Gen4 support Add support for R-Car Gen4 SoCs into the driver. While I2C on R-Car Gen4 does support some extra features (Slave Clock Stretch Select), for now it is treated the same as I2C on R-Car Gen3, which let us share the same driver.
