soc: microchip: add mpfs gpio interrupt mux driver

2026-03-31T13:13:14Z

On PolarFire SoC there are more GPIO interrupts than there are interrupt lines available on the PLIC, and a runtime configurable mux is used to decide which interrupts are assigned direct connections to the PLIC & which are relegated to sharing a line. Add a driver so that Linux can set the mux based on the interrupt mapping in the devicetree.

soc: microchip: add mfd drivers for two syscon regions on PolarFire SoC

2025-10-29T16:22:37Z

The control-scb and mss-top-sysreg regions on PolarFire SoC both fulfill multiple purposes. The former is used for mailbox functions in addition to the temperature & voltage sensor while the latter is used for clocks, resets, interrupt muxing and pinctrl. Signed-off-by: Conor Dooley

soc: microchip: Fix POLARFIRE_SOC_SYS_CTRL input prompt

2024-01-22T16:39:40Z

The symbol's prompt should be a one-line description, instead of just duplicating the symbol name. Signed-off-by: Geert Uytterhoeven Signed-off-by: Conor Dooley

soc: microchip: mpfs: enable access to the system controller's flash

2023-12-06T12:06:18Z

The system controller has a flash that contains images used to reprogram the FPGA using IAP (In-Application Programming). Introduce a function that allows a driver with a reference to the system controller to get one to a flash device attached to it. Signed-off-by: Conor Dooley
