From 90742c5496f3bf76203c0759f783444af10fb61a Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 28 Oct 2020 13:30:10 +0800 Subject: hw/riscv: microchip_pfsoc: Hook the I2C1 controller The latest SD card image [1] released by Microchip ships a Linux kernel with built-in PolarFire SoC I2C driver support. The device tree file includes the description for the I2C1 node hence kernel tries to probe the I2C1 device during boot. It is enough to create an unimplemented device for I2C1 to allow the kernel to continue booting to the shell.
