Subject: [PATCH 2/3] net: sun8i_emac: Add support for the H6 variant
Date: Thu,  7 May 2020 18:10:51 -0500	[thread overview]
Message-ID: <20200507231052.23706-2-samuel@sholland.org> (raw)
In-Reply-To: <20200507231052.23706-1-samuel@sholland.org>

The H6 EMAC is very similar to the H3 variant, except that it uses the
same pinmux as R40. Add support for it.
