pinctrl: bcm281xx: Use "unsigned int" instead of bare "unsigned"

2025-06-04T12:42:02+00:00

[ Upstream commit 07b5a2a13f4704c5eae3be7277ec54ffdba45f72 ] Replace uses of bare "unsigned" with "unsigned int" to fix checkpatch warnings. No functional change.

pinctrl: bcm281xx: Fix incorrect regmap max_registers value

2025-03-22T19:50:37+00:00

[ Upstream commit 68283c1cb573143c0b7515e93206f3503616bc10 ] The max_registers value does not take into consideration the stride; currently, it's set to the number of the last pin, but this does not accurately represent the final register. Fix this by multiplying the current value by 4.

pinctrl: Use device_get_match_data()

[ Upstream commit 63bffc2d3a99eaabc786c513eea71be3f597f175 ] Use preferred device_get_match_data() instead of of_match_device() to get the driver match data.

pinctrl: nsp-gpio: Silence probe deferral messages

2023-08-10T08:41:20+00:00

We can have gpiochip_add_data() return -EPROBE_DEFER which will make us produce the "unable to add GPIO chip" message which is confusing. Use dev_err_probe() to silence probe deferral messages.

pinctrl: Explicitly include correct DT includes

2023-07-20T19:41:24+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Pull pin control updates from Linus Walleij: "Mostly drivers! Nothing special: some new Qualcomm chips as usual, and the new NXP S32 and nVidia BlueField-3. Core changes: - Make a lot of pin controllers with GPIO and irqchips immutable, i.e. not living structs, but const structs. This is driving a changed initiated by the irqchip maintainers. New drivers: - New driver for the NXP S32 SoC pin controller - As part of a thorough cleanup and restructuring of the Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were folded into the Mediatek directory and the family is renamed "mtmips". The Ralink chips live on as Mediatek MIPS family where new variants can be added. As part of this work also the device tree bindings were reworked. - New subdriver for the Qualcomm SM7150 SoC. - New subdriver for the Qualcomm IPQ9574 SoC. - New driver for the nVidia BlueField-3 SoC. - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO. - Support for the Qualcomm PMI632 mixed signal circuit GPIO. Improvements: - Add some missing pins and generic cleanups on the Renesas r8a779g0 and r8a779g0 pin controllers. Generic Renesas extension for power source selection on several SoCs. - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver. - Several device tree binding cleanups as the binding YAML syntax is solidifying" * tag 'pinctrl-v6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (153 commits) pinctrl-bcm2835.c: fix race condition when setting gpio dir dt-bindings: pinctrl: qcom,sm8150: Drop duplicate function value "atest_usb2" dt-bindings: pinctrl: qcom: Add few missing functions pinctrl: qcom: spmi-gpio: Add PMI632 support dt-bindings: pinctrl: qcom,pmic-gpio: add PMI632 pinctrl: wpcm450: select MFD_SYSCON pinctrl: qcom ssbi-gpio: Convert to immutable irq_chip pinctrl: qcom ssbi-mpp: Convert to immutable irq_chip pinctrl: qcom spmi-mpp: Convert to immutable irq_chip pinctrl: plgpio: Convert to immutable irq_chip pinctrl: pistachio: Convert to immutable irq_chip pinctrl: pic32: Convert to immutable irq_chip pinctrl: sx150x: Convert to immutable irq_chip pinctrl: stmfx: Convert to immutable irq_chip pinctrl: st: Convert to immutable irq_chip pinctrl: mcp23s08: Convert to immutable irq_chip pinctrl: equilibrium: Convert to immutable irq_chip pinctrl: npcm7xx: Convert to immutable irq_chip pinctrl: armada-37xx: Convert to immutable irq_chip pinctrl: nsp: Convert to immutable irq_chip ...

pinctrl-bcm2835.c: fix race condition when setting gpio dir

2023-04-21T09:00:34+00:00

In the past setting the pin direction called pinctrl_gpio_direction() which uses a mutex to serialize this. That was changed to set the direction directly in the pin controller driver, but that lost the serialization mechanism. Since the direction of multiple pins are in the same register you can have a race condition, something that was in fact observed with the cec-gpio driver. Add a new spinlock to serialize writing to the FSEL registers.
