pinctrl: intel: Add code name documentation

2026-03-04T12:21:49+00:00

[ Upstream commit fc32c5725fbe1164d353400389d3e29d19960a3a ] Intel pinctrl drivers support large set of platforms and the IPs are often reused by their different variants, but it's currently not possible to figure out the exact driver that supports specific variant. Add user friendly documentation for them.

pinctrl: intel: Fix wrong bypass assignment in intel_pinctrl_probe_pwm()

2025-04-10T12:39:21+00:00

[ Upstream commit 0eee258cdf172763502f142d85e967f27a573be0 ] When instantiating PWM, the bypass should be set to false. The field is used for the selected Intel SoCs that do not have PWM feature enabled in their pin control IPs.

pinctrl: intel: platform: Add Panther Lake to the list of supported

2024-10-03T10:14:31+00:00

Intel Panther Lake is supported by the generic platform driver, so add it to the list of supported in Kconfig. Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: intel: platform: use semicolon instead of comma in ncommunities assignment

2024-09-30T11:35:23+00:00

Substitute the comma with a semicolon in the `ncommunities` assignment for better readability and consistency with common C coding style. Signed-off-by: Javier Carrasco Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: intel: platform: fix error path in device_for_each_child_node()

2024-09-30T11:35:23+00:00

The device_for_each_child_node() loop requires calls to fwnode_handle_put() upon early returns to decrement the refcount of the child node and avoid leaking memory if that error path is triggered. There is one early returns within that loop in intel_platform_pinctrl_prepare_community(), but fwnode_handle_put() is missing. Instead of adding the missing call, the scoped version of the loop can be used to simplify the code and avoid mistakes in the future if new early returns are added, as the child node is only used for parsing, and it is never assigned.

intel-pinctrl for v6.12-1 * Enable High Impedance pin configuration support for Intel pin control * Miscellaneous small improvements here and there The following is an automated git shortlog grouped by driver: baytrail: - Drop duplicate return statement intel: - Constify struct intel_pinctrl parameter - Inline intel_gpio_community_irq_handler() - Introduce for_each_intel_gpio_group() helper et al. - Constify intel_get_community() returned object - Implement high impedance support - Add __intel_gpio_get_direction() helper - Refactor __intel_gpio_set_direction() to be more useful - Move debounce validation out of the lock Signed-off-by: Linus Walleij

pinctrl: intel: Constify struct intel_pinctrl parameter

2024-09-05T15:09:28+00:00

There are a few functions that do not and should not change the state of the pin control object. Constify the respective parameter. Signed-off-by: Andy Shevchenko Acked-by: Mika Westerberg

pinctrl: baytrail: Drop duplicate return statement

2024-09-04T10:31:05+00:00

No need to repeat 'return ret;' inside and outside conditional. Just use one outside conditional for both cases. Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: intel: Inline intel_gpio_community_irq_handler()

2024-09-03T14:08:42+00:00

Since we have for_each_intel_pad_group() helper, there is no advantage of having intel_gpio_community_irq_handler(). Inline it into intel_gpio_irq(). Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: intel: Introduce for_each_intel_gpio_group() helper et al.

2024-08-30T18:47:36+00:00

Introduce a helper macro for_each_intel_gpio_group() et al. With those in place, update the users.
