pinctrl: intel: Try to retrieve driver data for pure platform drivers

2026-09-03T13:42:32+00:00

The Denverton pinctrl device can be instantiated by the Intel LPC driver as an MFD platform device named "denverton-pinctrl". On affected systems the platform device does not carry the INTC3000 ACPI match data itself. As a result, intel_pinctrl_probe_by_hid() fails to obtain the SoC data using device_get_match_data() and returns -ENODATA. This might be also true for other platforms that can be enumerated by ACPI _HID. Fix the above by trying the pure platform driver data in case the firmware node is not set or doesn't carry the necessary information.

pinctrl: intel: constify parameter in intel_pinctrl_get_soc_data()

2026-09-03T13:42:32+00:00

The parameter of intel_pinctrl_get_soc_data() is not going to be modified. Mark it with const qualifier. Suggested-by: Mika Westerberg Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: intel: Move intel_pinctrl_get_soc_data() upper in the code

2026-09-03T13:42:32+00:00

While it's exported function, move it upper in the code to be on top of the local user. This brings a consistency to the follow change that will introduce similar helper for the intel_pinctrl_probe_by_hid(). Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: intel: Remove redundant dev_err_probe()

2026-07-17T16:57:43+00:00

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"), devm_request_irq() automatically logs detailed error messages on failure. Remove the now-redundant driver-specific dev_err_probe() calls. Signed-off-by: Pan Chuang Signed-off-by: Andy Shevchenko

pinctrl: intel: move PWM base computation past feature check

2026-05-18T07:01:17+00:00

Compute base inside intel_pinctrl_probe_pwm() only after the PINCTRL_FEATURE_PWM and CONFIG_PWM_LPSS checks have passed. Tidy up; no functional change.

pinctrl: intel: Enable 3-bit PAD_OWN feature

2026-03-19T06:58:53+00:00

Starting from revision 1.1 of the Chassis specification the PAD_OWN is represented by 3 bits instead of 2 bits in the previous revisions. Update the driver to support this feature. Signed-off-by: Andy Shevchenko

pinctrl: intel: Fix the revision for new features (1kOhm PD, HW debouncer)

2026-03-19T06:58:53+00:00

The 1kOhm pull down and hardware debouncer are features of the revision 0.92 of the Chassis specification. Fix that in the code accordingly. Signed-off-by: Andy Shevchenko

pinctrl: intel: Improve capability support

2026-03-19T06:58:52+00:00

The register space of a certain capability starts at the offset just after the respective node in the capability list. It means that there are no fixed offsets for them from SoC to SoC generation and they have to be calculated at run-time. Improve capability support by adding the respective calculation algorithm and in the result enable PWM on more platforms that currently may use the wrong register. Signed-off-by: Andy Shevchenko

pinctrl: intel: Align Copyright note with corporate guidelines

2026-02-06T11:05:29+00:00

The Copyright note must follow the Copyright (C) Intel Corporation template, where (C) is always capitalised and either a single year or a range. Update the Intel pin control drivers to follow. Signed-off-by: Andy Shevchenko Acked-by: Mika Westerberg Signed-off-by: Linus Walleij

pinctrl: intel: Remove duplicate error messages

2026-01-28T13:26:27+00:00

The pin control core is covered to report any error via message. Since that it's not needed in the callers. Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko
