Subject: [PATCH 0/3] add support for Allwinner R40 CAN controller
Date: Mon, 22 Nov 2021 13:46:13 +0300 [thread overview]
Message-ID: <20211122104616.537156-1-boger@wirenboard.com> (raw)
Allwinner R40 (also known as A40i, T3, V40) has a CAN controller. The
controller is the same as in earlier A10 and A20 SoCs, but needs reset
line to be deasserted before use.
This patch series introduce new compatible for R40 CAN controller,
add support for reset line in driver and add the corresponding nodes
to the SoC .dtsi file.
The CAN IP was documented in early V40 datasheet [1]. It also fully
supported in vendor BSP. However, CAN description was removed from
more recent A40i, T3 and R40 user manuals and datasheets.
Anyway, we verified that the CAN controller is indeed there and tested
it extensively on A40i-based custom hardware [2].
