Subject: [PATCH 3/3] ARM: dts: sun8i: r40: add node for CAN controller
Date: Mon, 22 Nov 2021 13:46:16 +0300 [thread overview]
Message-ID: <20211122104616.537156-4-boger@wirenboard.com> (raw)
In-Reply-To: <20211122104616.537156-1-boger@wirenboard.com>
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 adds a CAN node and the corresponding pinctrl descriptions.
