If so, it needs to be merged with the TCB schema Alexandre is working on. > > Signed-off-by: Kamel Bouhara <kamel.bouhara@bootlin.com> > --- > Changes from v3: > - Updated the brand name: s/atmel/microchip/. > > Changes from v2: > - Fixed errors reported by dt_binding_check > > .../counter/microchip-tcb-capture.yaml | 33 +++++++++++++++++++ > 1 file changed, 33 insertions(+) > create mode 100644 Documentation/devicetree/bindings/counter/microchip-tcb-capture.yaml

Describe the devicetree binding for the Microchip TCB module. Each counter blocks exposes three independent counters. However, when configured in quadrature decoder, both channel <0> and <1> are required for speed/position and rotation capture (yet only the position is captured).
