2021-05-05gpiolib: acpi: Add quirk to ignore EC wakeups on Dell Venue 10 Pro 5055Hans de Goede1-0/+14
Like some other Bay and Cherry Trail SoC based devices the Dell Venue 10 Pro 5055 has an embedded-controller which uses ACPI GPIO events to report events instead of using the standard ACPI EC interface for this. The EC interrupt is only used to report battery-level changes and it keeps doing this while the system is suspended, causing the system to not stay suspended. Add an ignore-wake quirk for the GPIO pin used by the EC to fix the spurious wakeups from suspend.

2021-05-05gpio: sch: Hook into ACPI GPE handler to catch GPIO edge eventsAndy Shevchenko2-1/+83
Neither the ACPI description on Intel Minnowboard (v1) platform provides the required information to establish a generic handling nor the hardware capable of doing it. According to the data sheet the hardware can generate SCI events. Therefore, we need to hook from the driver into GPE handler of the ACPI subsystem in order to catch and report GPIO-related events. Validated on the Inlel Minnowboard (v1) platform and Intel Galileo Gen 2. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org>

2021-05-05gpio: Add Realtek Otto GPIO supportSander Vanheule3-0/+339
Realtek MIPS SoCs (platform name Otto) have GPIO controllers with up to 64 GPIOs, divided over two banks. Each bank has a set of registers for 32 GPIOs, with support for edge-triggered interrupts. Each GPIO bank consists of four 8-bit GPIO ports (ABCD and EFGH). Most registers pack one bit per GPIO, except for the IMR register, which packs two bits per GPIO (AB-CD). Although the byte order is currently assumed to have port A..D at offset 0x0..0x3, this has been observed to be reversed on other, Lexra-based, SoCs (e.g. RTL8196E/97D/97F). Interrupt support is disabled for the fallback devicetree-compatible 'realtek,otto-gpio'. This allows for quick support of GPIO banks in which the byte order would be unknown. In this case, the port ordering in the IMR registers may not match the reversed order in the other registers (DCBA, and BA-DC or DC-BA).

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "There is a lot going on! Core changes: - A semantic change to handle pinmux and pinconf in explicit order while up until now we depended on the semantic order in the device tree. The device tree is a functional programming language and does not imply any order, so the right thing is for the pin control core to provide these semantics. - Add a new pinmux-select debugfs file which makes it possible to go in and select functions for a pin manually (iteratively, at the prompt) for debugging purposes. - Fixes to gpio regmap handling for a new pin control driver making use of regmap-gpio. - Use octal permissions on debugfs files. New drivers: - A massive rewrite of the former custom pin control driver for MIPS Broadcom devices to instead use the pin control subsystem. New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368, BCM63268 and BCM6318 SoC variants are implemented. - Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are supported. - Support for the Rockchip RK3568/RK3566 pin controller. - Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000. - Support for Mediatek MTK8195. - Add a new Xilinx ZynqMP pin control driver. Driver improvements and non-urgent fixes: - Modularization and improvements of the Rockchip drivers. - Some new pins added to the description of new Renesas SoCs. - Clarifications of the GPIO base calculation in the Intel driver. - Fix the function names for the MPP54 and MPP55 pins in the Armada CP110 pin controller. - GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350. - Support for ACPI probing of the Qualcomm SC8180x. - Fix interrupt clear status on rockchip - Fix some missing pins on the Ingenic JZ4770, some semantic fixes for the behaviour of the Ingenic pin controller.

As we are using cpu_pm to save and restore context, we must also save and restore the GPIO sysconfig register. This is needed because we are not calling PM runtime functions at all with cpu_pm. We need to save the sysconfig on idle as it's value can get reconfigured by PM runtime and can be different from the init time value. Device specific flags like "ti,no-idle-on-init" can affect the init value.

2021-03-26gpiolib: Reuse device's fwnode to create IRQ domainAndy Shevchenko1-11/+4
When IRQ domain is created for an ACPI case, the name of it becomes unknown-%d since for now it utilizes of_node member only and doesn't consider fwnode case. Convert IRQ domain creation code to utilize fwnode instead. Before/After the change on Intel Galileo Gen 2 with two GPIO (IRQ) controllers: unknown-1 ==> \_SB.PCI0.GIP0.GPO unknown-2 ==> \_SB.NIO3 Due to the nature of this change we may also deduplicate the WARN():s because in either case (DT or ACPI) the fwnode will be set correctly and %pfw is an equivalent to what the current code prints as a prefix.

2021-03-08gpiolib: Read "gpio-line-names" from a firmware nodeAndy Shevchenko1-8/+4
On STM32MP1, the GPIO banks are subnodes of pin-controller@50002000, see arch/arm/boot/dts/stm32mp151.dtsi. The driver for pin-controller@50002000 is in drivers/pinctrl/stm32/pinctrl-stm32.c and iterates over all of its DT subnodes when registering each GPIO bank gpiochip. Each gpiochip has: - gpio_chip.parent = dev, where dev is the device node of the pin controller - gpio_chip.of_node = np, which is the OF node of the GPIO bank Therefore, dev_fwnode(chip->parent) != of_fwnode_handle(chip.of_node), i.e. pin-controller@50002000 != pin-controller@50002000/gpio@5000*000. The original code behaved correctly, as it extracted the "gpio-line-names" from of_fwnode_handle(chip.of_node) = pin-controller@50002000/gpio@5000*000. To achieve the same behaviour, read property from the firmware node.

2021-03-08gpio: pca953x: Set IRQ type when handle Intel Galileo Gen 2Andy Shevchenko1-55/+23
The commit 0ea683931adb ("gpio: dwapb: Convert driver to using the GPIO-lib-based IRQ-chip") indeliberately made a regression on how IRQ line from GPIO I²C expander is handled. I.e. it reveals that the quirk for Intel Galileo Gen 2 misses the part of setting IRQ type which previously was predefined by gpio-dwapb driver. Now, we have to reorganize the approach to call necessary parts, which can be done via ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk. Without this fix and with above mentioned change the kernel hangs on the first IRQ event with: gpio gpiochip3: Persistence not supported for GPIO 1 irq 32, desc: 62f8fb50, depth: 0, count: 0, unhandled: 0 ->handle_irq(): 41c7b0ab, handle_bad_irq+0x0/0x40 ->irq_data.chip(): e03f1e72, 0xc2539218 ->action(): 0ecc7e6f ->action->handler(): 8a3db21e, irq_default_primary_handler+0x0/0x10 IRQ_NOPROBE set unexpected IRQ trap at vector 20 Fixes: ba8c90c61847 ("gpio: pca953x: Override IRQ for one of the expanders on Galileo Gen 2") Depends-on: 0ea683931adb ("gpio: dwapb: Convert driver to using the GPIO-lib-based IRQ-chip") Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org>
