Subject: [PATCH v4 0/6] phy: phy-can-transceiver: Support TJA1048/TJA1051
Date: Mon, 01 Sep 2025 11:18:10 +0800 [thread overview]
Message-ID: <20250901-can-v4-0-e42b5fe2cf9e@nxp.com> (raw)
TJA1048 is a Dual channel can transceiver with Sleep mode supported.
TJA1051 is a Single Channel can transceiver with Sleep mode supported.
To support them:
patch 1: add binding doc
patch 2/3: To support dual channel,
- Introduce new flag CAN_TRANSCEIVER_DUAL_CH to indicate the phy
has two channels.
- Introduce can_transceiver_priv as a higher level encapsulation for
phy, mux_state, num_ch.
- Alloc a phy for each channel
patch 4,5,6: Update dts to use phys
Signed-off-by: Peng Fan <peng.fan@nxp.com>
