git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "The two large chunks is the header clean-up from Andy and the Qualcomm DT bindings clean-up from Krzysztof. Each which could give rise to conflicts, but I haven't seen any. The YAML conversions happening around the device tree is the biggest item in the series and is the result of Rob Herrings ambition to autovalidate these trees against strict schemas and it is paying off in lots of bugs found and ever prettier device trees. Sooner or later the transition will be complete, Krzysztof is fixing up all of the Qualcomm stuff, which is pretty voluminous. Core changes: - minor but nice and important documentation clean-ups New drivers: - subdriver for the Qualcomm SDM670 SoC - subdriver for the Intel Moorefield SoC - trivial support for the NXP Freescale i.MXRT1170 SoC Other changes and improvements - major clean-up of the Qualcomm pin control device tree bindings by Krzysztof - major header clean-up by Andy - some immutable irqchip clean-up for the Actions Semiconductor and Nuvoton drivers - GPIO helpers for The Cypress cy8c95x0 driver - bias handling in the Mediatek MT7986 driver - remove the unused pins-are-numbered concept that never flew" * tag 'pinctrl-v6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (231 commits) pinctrl: thunderbay: fix possible memory leak in thunderbay_build_functions() dt-bindings: pinctrl: st,stm32: Deprecate pins-are-numbered dt-bindings: pinctrl: mediatek,mt65xx: Deprecate pins-are-numbered pinctrl: stm32: Remove check for pins-are-numbered pinctrl: mediatek: common: Remove check for pins-are-numbered pinctrl: qcom: remove duplicate included header files pinctrl: sunxi: d1: Add CAN bus pinmuxes pinctrl: loongson2: Fix some const correctness pinctrl: pinconf-generic: add missing of_node_put() pinctrl: intel: Enumerate PWM device when community has a capability pwm: lpss: Rename pwm_lpss_probe() --> devm_pwm_lpss_probe() pwm: lpss: Allow other drivers to enable PWM LPSS pwm: lpss: Include headers we are the direct user of pwm: lpss: Rename MAX_PWMS --> LPSS_MAX_PWMS pwm: Add a stub for devm_pwmchip_add() pinctrl: k210: call of_node_put() pinctrl: starfive: Use existing variable gpio dt-bindings: pinctrl: semtech,sx150xq: fix match patterns for 16 GPIOs matching pinconf-generic: fix style issues in pin_config_param doc pinctrl: pinctrl-loongson2: fix Kconfig dependency ...
2022-10-24pinctrl: zynqmp: Add missing header(s)Andy Shevchenko1-1/+4
Do not imply that some of the generic headers may be always included. Instead, include explicitly what we are direct user of. While at it, sort headers alphabetically. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2022-10-18Revert "pinctrl: pinctrl-zynqmp: Add support for output-enable and ↵Sai Krishna Potthuri1-9/+0
bias-high-impedance" This reverts commit ad2bea79ef0144043721d4893eef719c907e2e63. On systems with older PMUFW (Xilinx ZynqMP Platform Management Firmware) using these pinctrl properties can cause system hang because there is missing feature autodetection. When this feature is implemented in the PMUFW, support for these two properties should bring back.

Add support to handle 'output-enable' and 'bias-high-impedance' configurations. As part of the output-enable configuration, ZynqMP pinctrl driver takes care of removing the pins from tri-state.

2022-01-28pinctrl: zynqmp: Revert "Unify pin naming"Gerhard Engleder1-6/+4
This reverts commit 54784ff24971ed5bd3f1056edce998148709d0a7. This patch changes the pin names from "MIO%d" to "MIO-%d", but all dts in arch/arm64/boot/dts/xilinx still use the old name. As a result my ZCU104 has no output on serial terminal and is not reachable over network.

2021-11-19pinctrl: zynqmp: Unify pin namingAndy Shevchenko1-4/+6
Since we have devm_kasprintf_strarray() helper, which is used in the rest of pin control drivers, it makes sense to switch this driver to it. The pin names are not part of any ABI and hence there will be no regression based on that. Otherwise all generated pin names will follow the same schema in the pin control subsystem.

It's not necessary to unregister pin controller device registered with devm_pinctrl_register() and using pinctrl_unregister() leads to a double free.
