Merge tag 'intel-pinctrl-v6.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into devel
intel-pinctrl for v6.7-1 * Merge "Drop runtime PM support for Baytrail and Lynxpoint pinctrl" (Raag) * Small improvements here and there in the Intel pin control drivers (Raag) * Switch to RAII for locking in the Intel core and Cherry View drivers * Enable non-ACPI enumeration in the Intel Denverton driver * Use MODULE_DEVICE_TABLE() instead of MODULE_ALIAS() in a couple of drivers * Introduce array_size.h and use in in the Intel pin control drivers The following is an automated git shortlog grouped by driver: baytrail: - Replace kernel.h by what is actually being used - drop runtime PM support - fix debounce disable case broxton: - Replace MODULE_ALIAS() with MODULE_DEVICE_TABLE() cherryview: - reduce scope of PIN_CONFIG_BIAS_HIGH_IMPEDANCE case - Convert to platform remove callback returning void - Simplify code with cleanup helpers - Avoid duplicated I/O - Replace kernel.h by what is actually being used denverton: - Replace MODULE_ALIAS() with MODULE_DEVICE_TABLE() - Enable platform device in the absence of ACPI enumeration intel: - fetch community only when we need it - refine intel_config_set_pull() function - Replace kernel.h by what is actually being used - Simplify code with cleanup helpers lynxpoint: - Replace kernel.h by what is actually being used - drop runtime PM support merrifield: - Replace kernel.h by what is actually being used moorefield: - Replace kernel.h by what is actually being used Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
