pinctrl: freescale: mxs: Fix refcount of child

2024-06-26T09:59:31+00:00

of_get_next_child() will increase refcount of the returned node, need
use of_node_put() on it when done.

Per current implementation, 'child' will be override by
for_each_child_of_node(np, child), so use of_get_child_count to avoid
refcount leakage.

pinctrl: imx: support SCMI pinctrl protocol for i.MX95

2024-06-17T07:26:18+00:00

The generic pinctrl-scmi.c driver could not be used for i.MX95 because
i.MX95 SCMI firmware not supports functions, groups or generic
'Pin Configuration Type and Enumerations' listed in SCMI Specification.

i.MX95 System Control Management Interface(SCMI) firmware only supports
below pin configuration types which are OEM specific types:
    192: PIN MUX
    193: PIN CONF
    194: DAISY ID
    195: DAISY VAL

To Support fsl,pins property together with SCMI OEM protocol, add this
driver.

pinctrl: imx: Convert to use func member

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

pinctrl: freescale: imx8ulp: fix module autoloading

2024-04-17T08:43:50+00:00

Add MODULE_DEVICE_TABLE(), so the module could be properly autoloaded
based on the alias from of_device_id table.  Pin controllers are
considered core components, so usually they are built-in, however these
can be built and used as modules on some generic kernel.

pinctrl: imx: Use temporary variable to hold pins

2023-12-01T14:00:20+00:00

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

2023-10-10T11:41:37+00:00

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.
