Merge tag 'intel-pinctrl-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into devel
intel-pinctrl for v5.6-1 * Tiger Lake appears to have _HID enumeration, thus driver has been updated * Coffee Lake-S has the same IP as Sunrisepoint, thus ID has been added * Baytrail has got more clean ups and bug fixes, such as direct IRQ handling * Lynxpoint GPIO has been converted to true pin control driver * The common driver now uses IRQ chip enumeration via GPIO chip The following is an automated git shortlog grouped by driver: baytrail: - Replace WARN with dev_info_once when setting direct-irq pin to output - Do not clear IRQ flags on direct-irq enabled pins - Reuse struct intel_pinctrl in the driver - Use local variable to keep device pointer - Keep pointer to struct device instead of its container - Use GPIO direction definitions - Move IRQ valid mask initialization to a dedicated callback - Group GPIO IRQ chip initialization - Allocate IRQ chip dynamic cherryview: - Use GPIO direction definitions intel: - Pass irqchip when adding gpiochip - Add GPIO <-> pin mapping ranges via callback - Share struct intel_pinctrl for wider use - Use GPIO direction definitions lynxpoint: - Update summary in the driver - Switch to pin control API - Add GPIO <-> pin mapping ranges via callback - Implement ->pin_dbg_show() - Add pin control operations - Reuse struct intel_pinctrl in the driver - Add pin control data structures - Implement intel_gpio_get_direction callback - Implement ->irq_ack() callback - Move ownership check to IRQ chip - Move lp_irq_type() closer to IRQ related routines - Move ->remove closer to ->probe() - Extract lp_gpio_acpi_use() for future use - Convert unsigned to unsigned int - Switch to memory mapped IO accessors - Keep pointer to struct device instead of its container - Relax GPIO request rules - Assume 2 bits for mode selector - Use standard pattern for memory allocation - Use %pR to print IO resource - Drop useless assignment - Correct amount of pins - Use raw_spinlock for locking - Move GPIO driver to pin controller folder sunrisepoint: - Add Coffee Lake-S ACPI ID - Add missing Interrupt Status register offset tigerlake: - Tiger Lake uses _HID enumeration
