[PATCH v2 0/5] phy: phy-can-transceiver: Support TJA1048/TJA1051

Posted by Peng Fan 1 month, 1 week ago

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: 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 3,4,5: Update dts to use phys
