Subject: ARM: dts: LogicPD Torpedo: Fix I2C1 pinmux
From: Adam Ford <aford173@gmail.com>
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

This commit was reverted in 4.4.122:
8d02a5519885 Revert "ARM: dts: LogicPD Torpedo: Fix I2C1 pinmux"
Is this a mistake that it came back again?

It showed up in 4.16-rc4. Should it be reverted again in Linus's tree?
If so, please do so and I'll take the revert.
