Subject: [PATCH v3 0/5] Microchip mpfs/pic64gx pinctrl

From: Conor Dooley <conor.dooley@...rochip.com>

Hey Linus,

Here's a v3, with the COMPILE_TEST added, and a select that the lkp bot
told me that I was missing when I pushed it yesterday for testing.

There's a tag below for you to pull that has the syscon binding that
gets edited in this series, since that's not in mainline yet.

Cheers,
Conor.

Changes in v3:
- Add COMPILE_TEST to drivers
- Drop a TODO
- Add select for GENERIC_PINCONF

The binding dep mentioned above is available here:

  dt-bindings: soc: microchip: document the simple-mfd syscon on PolarFire SoC (2025-10-21 14:29:34 +0100)

----------------------------------------------------------------
mpfs pinctrl binding base

The pinctrl binding patch for iomux0 mpfs adds a ref to itself to the
syscon/mfd mss-top-sysreg binding, and therefore needs that file to
exist.
