Subject: ARM: dts: LogicPD Torpedo: Fix I2C1 pinmux

From: Adam Ford <[email protected]>

commit 74402055a2d3ec998a1ded599e86185a27d9bbf4 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 time.

This correctly sets the I2C1 pinmuxing so it can operate at 2.6MHz

Fixes 687c27676151 ("ARM: dts: Add minimal support for LogicPD Torpedo

DM3730 devkit")
