Subject: [PATCH 0/9] ARM: sun9i: a80: Enable GMAC
Date: Wed, 6 Feb 2019 11:32:30 +0800 [thread overview]
Message-ID: <20190206033239.3619-1-wens@csie.org> (raw)
Hi everyone,
On the Allwinner A80, the PIO pin controller includes configuration
registers to set the I/O voltage. These must match the actual voltage
provided externally. A mismatch results in signals not being passed
through.
With the new PIO pin-bank regulator supply support in place, we can
tack on support for setting up these registers.
This in turn allows us to enable the GMAC, which runs at a reduced
2.5V for RGMII, instead of the standard 3.0V or 3.3V.
Please have a look.
Regards
ChenYu
