This reverts commit d922b54e942ee9c798b0d688b025362a24d864ea, reversing changes made to 3f0245e23a176e78f00a760291b8e4f88d01d77e. The SH maintainer has indicated that he want to carry these changes in the SH tree instead, and need more time to review and merge the changes, so reverting it out from my tree.

pinctrl: renesas: gpio: support software nodes for function GPIOs

2026-07-10T19:04:18Z

This patch extends the sh-pfc GPIO driver to support software-node-based configuration for the secondary 'function' GPIO chip. While the primary GPIO chip typically uses the firmware node attached to the parent platform device, the secondary chip should target a specific child node to avoid ambiguity when defining GPIO hogs or properties. Update gpio_function_setup() to look for a child node named 'functions', but only when the parent is a software node. This ensures the behavior is restricted to legacy platforms being migrated to software nodes.

pinctrl: renesas: gpio: isolate function gpiochip from parent fwnode

2026-07-10T19:04:18Z

The sh-pfc driver registers two separate gpiochip instances: one for real GPIOs and another for function GPIOs. Since both share the same parent platform device, gpiolib's fallback logic causes both chips to share the same firmware node (fwnode). This causes ambiguity when using software nodes to describe GPIOs, as gpiolib may apply hogs meant for one chip to the other if they share the same node. Explicitly set gc->fwnode to ERR_PTR(-ENODEV) for the function GPIO chip. This satisfies gpiolib's check for an existing fwnode and prevents it from falling back to the parent device's node, while ensuring that no actual properties or hogs are found on the function chip unless explicitly assigned later.

pinctrl: renesas: rza2: Embed pins in the priv struct

2026-06-30T10:03:56Z

Turn the separately allocated pinctrl_pin_desc array into a flexible array member of struct rza2_pinctrl_priv, annotated with __counted_by(npins). Compute the pin count before allocation so struct_size() can size the combined object, and the two allocations can be collapsed into one. Change npins to unsigned int to avoid potential overflow/underflow errors.

pinctrl: renesas: rzg2l: Use raw_spinlock_irqsave() on power source update

2026-06-05T09:44:54Z

The rest of the driver uses raw_spin_lock_irqsave() and raw_spin_unlock_irqrestore() for locking. To avoid concurrency issues or deadlocks, use raw_spinlock_irqsave() via the scoped_guard() helper for power source updates as well.

pinctrl: Use named initializers for platform_device_id arrays

2026-05-29T20:47:44Z

Named initializers are better readable and more robust to changes of the struct definition. This robustness is relevant for a planned change to struct platform_device_id replacing .driver_data by an anonymous unit. While touching these arrays unify spacing and usage of commas.
