pinctrl: imx: Convert to use grp member

2023-12-11T23:47:52Z

Convert drivers to use grp member embedded in struct group_desc, because other members will be removed to avoid duplication and desynchronisation of the generic pin group description.

pinctrl: imx: Use temporary variable to hold pins

2023-12-01T14:00:20Z

The pins are allocated from the heap, but in order to pass them as constant object, we need to use non-constant pointer. Achieve this by using a temporary variable.

pinctrl: mxs: Remove undocumented 'fsl,mxs-gpio' property

2023-10-10T11:41:37Z

The 'fsl,mxs-gpio' property is not documented in gpio-mxs.yaml, but the imx23 and imx28 dtsi describe the gpios as: compatible = "fsl,imx28-gpio", "fsl,mxs-gpio"; This gives schema warnings like: imx28-cfa10037.dtb: pinctrl@80018000: gpio@0:compatible: ['fsl,imx28-gpio', 'fsl,mxs-gpio'] is too long from schema $id: http://devicetree.org/schemas/gpio/gpio-mxs.yaml# "fsl,mxs-gpio" is only used inside pinctrl-mxs, but can be removed if the compatible check is done against fsl,imx23-gpio and fsl,imx28-gpio. Introduce is_mxs_gpio() and remove the need for "fsl,mxs-gpio". Tested on a imx28-evk.

pinctrl: Explicitly include correct DT includes

2023-07-20T19:41:24Z

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.

pinctrl: freescale: Fix a memory out of bounds when num_configs is 1

2023-06-16T12:59:03Z

The config passed in by pad wakeup is 1, when num_configs is 1, Configuration [1] should not be fetched, which will be detected by KASAN as a memory out of bounds condition. Modify to get configs[1] when num_configs is 2.

pinctrl: freescale: remove generic pin config core support

2023-03-07T13:15:37Z

No instance of "struct imx_pinctrl_soc_info" sets '.generic_pinconf = true', so all of this is effectively dead code. To make it easier to understand the actual code, remove all the unused cruft. This effectively reverts a5cadbbb081c ("pinctrl: imx: add generic pin config core support"). It was only in use by a single SOC (imx7ulp) for a few releases, and the commit message of dbffda08f0e9 ("pinctrl: fsl: imx7ulp: change to use imx legacy binding") suggests that it won't be used in the future. Certainly no new user has appeared in 20+ releases, and should the need arise, this can be dug out of git history again.

pinctrl: mxs: avoid defines prefixed with CONFIG

2022-12-29T01:05:16Z

Defines prefixed with "CONFIG" should be limited to proper Kconfig options, that are introduced in a Kconfig file. Here, expressions to convert pin configurations to booleans for pull-up, voltage and mA are macro definitions that begin with "CONFIG". To avoid defines prefixed with "CONFIG", rename these defines to begin with "PIN_CONFIG" instead. No functional change.
