2024-09-05gpio: cadence: Use helper function devm_clk_get_enabled()Zhang Zekun1-17/+6
devm_clk_get() and clk_prepare_enable() can be replaced by helper function devm_clk_get_enabled(). Let's use devm_clk_get_enabled() to simplify code and avoid calling clk_disable_unprepare().

2024-09-05gpio: sama5d2-piobu: convert comma to semicolonChen Ni1-9/+9
Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only.

2024-09-04gpio: stmpe: Fix IRQ related error messagesAndy Shevchenko1-8/+3
First of all, remove duplicate message that platform_get_irq() does already print. Second, correct the error message when unable to register a handler, which is broken in two ways: 1) the misleading 'get' vs. 'register'; 2) missing '\n' at the end. (Yes, for the curious ones, the dev_*() cases do not require '\n' and issue it automatically, but it's better to have them explicit) Fix all this here.

2024-09-02gpio: mpc8xxx: Add wake on GPIO supportMartyn Welch1-0/+29
The mpc8xxx GPIO can generate an interrupt on state change. This interrupt can be used to wake up the device from its sleep state if enabled to do so. Add required support to the driver so that the GPIO can be used in this way. In order for the GPIO to actually function in this way, it is necessary to also set the GPIO bit in the RCPM. This can be done via the device tree fsl,rcpm-wakeup property.

2024-08-05gpio: gpio-vf610: use u32 mask to handle 32 number gpiosHaibo Chen1-6/+6
This gpio controller support up to 32 pins per port. And all the register width is 32 bit. So here use u32 to replace the original unsigned long.

2024-08-01pwm: adp5585: Add Analog Devices ADP5585 supportClark Wang4-0/+193
The ADP5585 is a 10/11 input/output port expander with a built in keypad matrix decoder, programmable logic, reset generator, and PWM generator. This driver supports the PWM function using the platform device registered by the core MFD driver. The driver is derived from an initial implementation from NXP, available in commit 113113742208 ("MLK-25922-1 pwm: adp5585: add adp5585 PWM support") in their BSP kernel tree. It has been extensively rewritten.

2024-08-01mfd: adp5585: Add Analog Devices ADP5585 core supportHaibo Chen5-0/+346
The ADP5585 is a 10/11 input/output port expander with a built in keypad matrix decoder, programmable logic, reset generator, and PWM generator. This driver supports the chip by modelling it as an MFD device, with two child devices for the GPIO and PWM functions. The driver is derived from an initial implementation from NXP, available in commit 8059835bee19 ("MLK-25917-1 mfd: adp5585: add ADI adp5585 core support") in their BSP kernel tree.

2024-08-01dt-bindings: mfd: Add Analog Devices ADP5585Laurent Pinchart3-4/+99
The ADP5585 is a 10/11 input/output port expander with a built in keypad matrix decoder, programmable logic, reset generator, and PWM generator. These bindings model the device as an MFD, and support the GPIO expander and PWM functions. These bindings support the GPIO and PWM functions. Drop the existing adi,adp5585 and adi,adp5585-02 compatible strings from trivial-devices.yaml. They have been added there by mistake as the driver that was submitted at the same time used different compatible strings. We can take them over safely.
