Subject: [PATCH] mips: ralink: add accessors for MT7620 chipver and pkg
Date: Fri, 2 Nov 2018 03:07:19 +0100	[thread overview]
Message-ID: <20181102020713.GA880@makrotopia.org> (raw)
In-Reply-To: <20181016103806.GA1544@makrotopia.org>

The RT6352 wireless core included in all MT7620 chips is implemented
differently in MT7620A (TFBGA) and MT7620N (DR-QFN).
Hence provide accessor functions similar to the already existing
mt7620_get_eco() function which allow the rt2x00 wireless driver to
figure out which WiSoC it is being run on.
