mfd: stmpe: Remove #ifdef guards for PM related functions

2022-12-07T13:28:13Z

Use the new EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

mfd: stmpe: Switch to using gpiod API

2022-09-28T15:17:40Z

This patch switches the driver away from legacy gpio/of_gpio API to gpiod API, and removes use of of_get_named_gpio_flags() which I want to make private to gpiolib. We also need to patch relevant DTS files, as the original code relied on the fact that of_get_named_gpio_flags() would fetch any data encoded in GPIO flags, even if it does not reflect valid flags for a GPIO.

mfd: stmpe: Probe sub-function by compatible

2022-09-28T15:09:48Z

Use sub-function of_compatible during probe, instead of using the node name. The code should not rely on the node names during probe, in addition to that the previously hard-coded node names are not compliant to the latest naming convention (they are not generic and they use underscores), and it was broken by mistake already once [1].

mfd: stmpe: Remove rotator block from probe

2022-09-28T15:09:48Z

Remove rotator block from probe, it is not used in any device tree file, there is no related cell defined, it's just dead non-working code with no of_compatible for it. This is a preliminary change to allow probing by of_compatible and not by a fixed name.

mfd: stmpe: Support disabling sub-functions

2021-11-29T13:17:00Z

Add support of sub-functions disabling. It allows one to define an stmpe sub-function device in devicetree, but keep it disabled.

mfd: stmpe: Make stmpe_remove() return void

2021-11-05T14:40:26Z

Up to now stmpe_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.

mfd: Don't use irq_create_mapping() to resolve a mapping

2021-08-05T11:41:06Z

Although irq_create_mapping() is able to deal with duplicate mappings, it really isn't supposed to be a substitute for irq_find_mapping(), and can result in allocations that take place in atomic context if the mapping didn't exist. Fix the handful of MFD drivers that use irq_create_mapping() in interrupt context by using irq_find_mapping() instead.

mfd: stmpe: Revert "Constify static struct resource"

2021-04-14T15:03:22Z

In stmpe_devices_init(), the start and end field of these structs are modified, so they can not be const. Add a comment to those structs that lacked it to reduce the risk that this happens again. This reverts commit 8d7b3a6dac4eae22c58b0853696cbd256966741b.

mfd: stmpe: Constify static struct resource

2020-11-19T08:34:21Z

Constify a couple of static struct resource. The only usage of the structs is to assign their address to the resources field in the mfd_cell struct. This allows the compiler to put them in read-only memory. Done with the help of Coccinelle. Signed-off-by: Rikard Falkeborn Signed-off-by: Lee Jones
