From 31a4ac4d79d75baeede3edfa95515fd4169ef502 Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Mon, 5 Nov 2018 20:24:30 -0800 Subject: sun50i: A64: add support for R_I2C controller Allwinner A64 has a I2C controller, which is in the R_ MMIO zone and has two groups of pinmuxes on PL bank, so it's called R_I2C. Add support for this I2C controller and the pinmux which doesn't conflict with RSB.
