[PATCH v7 0/8] phy: phy-can-transceiver: Support TJA1048/TJA1051

[Peng Fan <peng.fan@nxp.com>]

TJA1048 is a Dual channel can transceiver with Sleep mode supported.
TJA105{1,7} 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: Simplify code
patch 5: Add TJA1051,7 support
Others: Update dts to use phys.

Changes in v7:
  Since got v6 comments from Marc and Vincent, I was busy on other
  stuff, so delay about one week to move to v7.
- Patch 1: Add R-b from Rob for dt-bindings
- For Patch 2,3: Switch to use flexible array for "struct can_transceiver_phy"
  per Marc. Use a local variable to avoid multiple pointer based access per
  Vincent. For mux_state I still keep it as phy chip level, so it is still
  in "struct can_transceiver_priv" as previous patch, so no array needed.
- Drop patch 5 which was to check gpio API return value. Since no issue
  reported, and error return value check here will make code looks ugly,
  I not find an elegant way to do this, so drop the patch for now.
  We may add it back in future

Changes in v6:
- Update dt-bindings per Krzysztof's comments
  "define if:then:, without any else:, for each variant"
- Add R-b from Frank

Changes in v5:
- Update patch 1 dt-bindings for TJA1051 and TJA1057 and allOf entries
  for them, per Conor's comments. Thanks Conor for detailed review on
  the dt-binding patch.
- Add two new patches patch {3,4} to simplify code and check return value of
  gpiod API.
- Add patch 6 because TJA1051 and TJA1057 use their own compatible strings
- Link to v4: https://lore.kernel.org/r/20250901-can-v4-0-e42b5fe2cf9e@nxp.com
