2021-07-01Merge tag 'pinctrl-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrlLinus Torvalds9-25/+899
Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.14 kernel. Not so much going on. No core changes, just drivers. The most interesting would be that MIPS Ralink is migrating to pin control and we have some bindings but not yet code for the Apple M1 pin controller. New drivers: - Last merge window we created a driver for the Ralink RT2880. We are now moving the Ralink SoC pin control drivers out of the MIPS architecture code and into the pin control subsystem. This concerns RT288X, MT7620, RT305X, RT3883 and MT7621. - Qualcomm SM6125 SoC pin control driver. - Qualcomm spmi-gpio support for PM7325. - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string) - Mediatek MT8365 SoC pin controller. - New device HID for the AMD GPIO controller. Improvements: - Pin bias config support for a slew of Renesas pin controllers. - Incremental improvements and non-urgent bug fixes to the Renesas SoC drivers. - Implement irq_set_wake on the AMD pin controller so we can wake up from external pin events. Misc: - Devicetree bindings for the Apple M1 pin controller, we will probably see a proper driver for this soon as well" * tag 'pinctrl-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (54 commits) pinctrl: ralink: rt305x: add missing include pinctrl: stm32: check for IRQ MUX validity during alloc() pinctrl: zynqmp: some code cleanups drivers: qcom: pinctrl: Add pinctrl driver for sm6125 dt-bindings: pinctrl: qcom: sm6125: Document SM6125 pinctrl driver dt-bindings: pinctrl: mcp23s08: add documentation for reset-gpios pinctrl: mcp23s08: Add optional reset GPIO pinctrl: mediatek: fix mode encoding pinctrl: mcp23s08: Fix missing unlock on error in mcp23s08_irq() pinctrl: bcm: Constify static pinmux_ops pinctrl: bcm: Constify static pinctrl_ops pinctrl: ralink: move RT288X SoC pinmux config into a new 'pinctrl-rt288x.c' file pinctrl: ralink: move MT7620 SoC pinmux config into a new 'pinctrl-mt7620.c' file pinctrl: ralink: move RT305X SoC pinmux config into a new 'pinctrl-rt305x.c' file pinctrl: ralink: move RT3883 SoC pinmux config into a new 'pinctrl-rt3883.c' file pinctrl: ralink: move MT7621 SoC pinmux config into a new 'pinctrl-mt7621.c' file pinctrl: ralink: move ralink architecture pinmux header into the driver pinctrl: single: config: enable the pin's input pinctrl: mtk: Fix mt8365 Kconfig dependency pinctrl: mcp23s08: fix race condition in irq handler ...
2021-06-30pinctrl: ralink: rt305x: add missing includeSergio Paracuellos1-0/+1
Header 'rt305x.h' is ralink architecture dependent file where other general definitions which are in 'ralink_regs.h' are being used. This 'rt305x.h' is only being included in two different files: 'rt305x.c' and 'pinctrl-rt305x.c'. When file 'pinctrl-rt305x.c' is being compiled definitions in 'ralink_regs.h' are need to build it properly. Hence, add missing include 'ralink_regs.h' in 'pinctrl-rt305x.c' source to avoid compilation problems.

2021-06-07pinctrl: ralink: move ralink architecture pinmux header into the driverSergio Paracuellos2-25/+58
Ralink architecture is making use of the header located in 'arch/mips/include/asm/mach-ralink/pinmux.h' to stablish the mechanisms to make derived SoCs to set its pin functions and groups. In order to move all architecture pinmux into a more accurate place which is 'drivers/pinctrl/ralink' we have to first of all move this file also there with a small modification which creates 'rt2880_pinmux_init' function to allow SoCs pinctrl drivers to pass its configuration to the common code located in 'pinctrl-rt2880.c' file.

2021-06-07pinctrl: ralink: rt2880: avoid to error in calls is pin is already enabledSergio Paracuellos1-1/+1
In 'rt2880_pmx_group_enable' driver is printing an error and returning -EBUSY if a pin has been already enabled. This begets anoying messages in the caller when this happens like the following: rt2880-pinmux pinctrl: pcie is already enabled mt7621-pci 1e140000.pcie: Error applying setting, reverse things back To avoid this just print the already enabled message in the pinctrl driver and return 0 instead to not confuse the user with a real bad problem.

Kernel test robot reported the following warning: 'warning: no previous prototype for 'rt2880_pinmux_init''. This function is the entry point for the platform driver and it is private to this driver. Hence declare it 'static' which is the correct thing to do fixing also this warning.

These Socs have 1-3 banks of 8-32 gpios. Rather then setting the muxing of each pin individually, these socs have mux groups that when set will effect 1-N pins. Pin groups have a 2, 4 or 8 different muxes.
