Subject[PATCH 0/7] dts: sun8i: add extra uart/i2c to H3
Message-ID<scedA-34F-19@gated-at.bofh.it>
From: Jorik Jonker <jorik@kippendief.biz>

This series is a follow-up to Martin Ayotte's efforts to add additional UARTS
and I2C ports to the AllWinner H3 SoC DTS files. In this series I explicitly
leave out i2c2, since this is not broken out on my boards, so I cannot verify if
it actually works.

After the patch, one enables for example uart1 on a opi+ like this from u-boot:
 => fdt set /soc/serial@01c28400 status okay

Regards,
Jorik

#1473503 — [PATCH 3/7] dts: sun8i-h3: add i2c0/i2c1 SoC peripherals

Fromjorik@kippendief.biz
Date2016-08-31 16:00 +0200
Subject[PATCH 3/7] dts: sun8i-h3: add i2c0/i2c1 SoC peripherals
Message-ID<scedB-34F-49@gated-at.bofh.it>
In reply to#1473497
From: Jorik Jonker <jorik@kippendief.biz>

This enables the i2c0/i2c1 peripherals of the SoC. There is actually a third
controller, but I do not have a board on hands on which i2c2 is exposed in such
a way that I can verify that it works.
