Subject: [PATCH v3 14/30] dt-bindings: update the Allwinner GPADC device tree binding for H3 & A83T
Date: Thu, 30 Aug 2018 17:45:02 +0200 [thread overview]
Message-ID: <20180830154518.29507-15-embed3d@gmail.com> (raw)
In-Reply-To: <20180830154518.29507-1-embed3d@gmail.com>
Allwinner H3 features a thermal sensor like the one in A33, but has its
register re-arranged, the clock divider moved to CCU (originally the
clock divider is in ADC) and added a pair of bus clock and reset.
Allwinner A83T features a thermal sensor similar to the H3, the ths clock,
the bus clock and the reset was removed from the CCU. The THS in A83T
has a clock that is directly connected and runs with 24 MHz.
Update the binding document to cover H3 and A83T.
