Subject: [PATCH 009/146] dt-bindings: update the Allwinner GPADC device tree
|
|
binding for H3 & A83T
|
|
|
|
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.
