dt-bindings: can: mpfs: document resets

2025-11-26T10:30:37Z

The CAN cores on Polarfire SoC both have a reset. The platform firmware brings both cores out of reset, but the linux driver must use them during normal operation. The resets should have been made required, but this is one of the things that can happen when the binding is written without driver support.

dt-bindings: can: m_can: Add wakeup properties

2025-10-17T09:02:27Z

The pins associated with m_can have to have a special configuration to be able to wakeup the SoC from some system states. This configuration is described in the wakeup pinctrl state while the default state describes the default configuration. Also add the sleep state which is already in use by some devicetrees. Also m_can can be a wakeup-source if capable of wakeup.

dt-bindings: can: renesas,rcar-canfd: Document RZ/G3E support

2025-05-21T12:31:23Z

Document support for the CAN-FD Interface on the RZ/G3E (R9A09G047) SoC, which supports up to six channels. The CAN-FD module on RZ/G3E is very similar to the one on both R-Car V4H and RZ/G2L, but differs in some hardware parameters: * No external clock, but instead has ram clock. * Support up to 6 channels. * 20 interrupts.
