Hi, I'm in the process of adding a device tree overlay for the PiFace Digital Raspberry Pi daughter board [0]. It's an mcp23s17 SPI GPIO port expander. In doing so, I noticed some errors with the mcp23s08 driver. This series adds my fixups to (which builds successfully): v5.8-13252-gcf4a66ae5e4a But I have only tested them on (rpi-5.4.y): v5.4.51-1078-g92834e4bb4ce They're quite trivial and backwards compatible, although I might be wrong about "interrupt-controller". Can someone please confirm? Many thanks, Thomas [0] https://github.com/raspberrypi/linux/pull/3794 Thomas Preston (3): pinctrl: mcp23s08: Fixup mcp23x17 regmap_config pinctrl: mcp23s08: Remove interrupt-controller devicetree: mcp23s08: Remove interrupt-controller .../bindings/pinctrl/pinctrl-mcp23s08.txt | 8 ----- drivers/pinctrl/pinctrl-mcp23s08.c | 35 +++++++++---------- drivers/pinctrl/pinctrl-mcp23s08.h | 2 +- 3 files changed, 18 insertions(+), 27 deletions(-) -- 2.26.2
