Subject: [PATCH v1 0/2] dt-bindings: CAN: MCP251XFD GPIO hog support and QCS6490 CAN enablement

This series introduces two changes:

1. Extend the MCP251XFD binding to allow GPIO hog child nodes. The
   MCP251XFD family can expose two pins as GPIOs. The binding already
   declares 'gpio-controller' and '#gpio-cells'. Adding a
   'patternProperties' entry permits boards to define hog nodes for default
   GPIO states at boot, which aligns with other GPIO controller bindings
   (e.g., microchip,mpfs-gpio).

2. Enable the MCP2518FD CAN controller on the QCS6490 RB3 Gen2 platform.
   The controller is connected via SPI3 and uses a 40 MHz oscillator.
   A GPIO hog for GPIO0 is included to configure the CAN transceiver in
   Normal mode during boot.
