| Subject: ARM: dts: LogicPD SOM-LV: Fix I2C1 pinmux |
| |
| From: Adam Ford <aford173@gmail.com> |
| |
| commit 84c7efd607e7fb6933920322086db64654f669b2 upstream. |
| |
| The pinmuxing was missing for I2C1 which was causing intermittent issues |
| with the PMIC which is connected to I2C1. The bootloader did not quite |
| configure the I2C1 either, so when running at 2.6MHz, it was generating |
| errors at times. |
| |
| This correctly sets the I2C1 pinmuxing so it can operate at 2.6MHz |
| |
| Fixes: ab8dd3aed011 ("ARM: DTS: Add minimal Support for Logic PD DM3730 |
| SOM-LV") |
