2021-12-02pinctrl/rockchip: fix gpio device creationJohn Keeping1-1/+1
GPIO nodes are not themselves busses, so passing rockchip_bank_match here is wrong. Passing NULL instead uses the standard bus match table which is more appropriate. devm_of_platform_populate() shows that this is the normal way to call of_platform_populate() from a device driver, so in order to match that more closely also add the pinctrl device as the parent for the newly created GPIO controllers. Specifically, using the wrong match here can break dynamic GPIO hogs as marking the GPIO bank as a bus means that of_platform_notify() will set OF_POPULATED on new child nodes and if this happens before of_gpio_notify() is called then the new hog will be skipped as OF_POPULATED is already set.

2021-11-26pinctrl: cherryview: Do not allow the same interrupt line to be used by 2 pinsHans de Goede1-8/+61
It is impossible to use the same interrupt line for 2 pins, this will result in the interrupts only being delivered to the IRQ handler for the pin for which chv_gpio_irq_type() was called last. The pinctrl-cherryview.c code relies on the BIOS to correctly setup the interrupt line, but there is a BIOS bug on at least the Medion Akoya E1239T and the GPD win models where both INT33FF:02 pin 8, used by the powerbutton and INT33FF:02 pin 21 used as IRQ input for the accelerometer are mapped to interrupt line 0. This causes 2 problems: 1. The accelerometer IRQ does not work, since the power button is probed later taking over the intr_lines[0] slot. 2. Since the accelerometer IRQ is not marked as wakeup, interrupt line 0 gets masked on suspend, causing the power button to not work to wake the system from suspend. Likewise on the Lenovo Yogabook, which has a touchscreen as keyboard and the keyboard half of the tablet also has a Wacom digitizer, the BIOS by default assigns the same interrupt line to the GPIOs used for their interrupts. Fix these problems by adding a check for this and assigning a new interrupt line to the 2nd pin for which chv_gpio_irq_type() gets called. With this fix in place the following 2 messages show up in dmesg on the Medion Akoya E1239T and the GPD win: cherryview-pinctrl INT33FF:02: interrupt line 0 is used by both pin 21 and pin 8 cherryview-pinctrl INT33FF:02: changing the interrupt line for pin 8 to 15 And the following gets logged on the Lenovo Yogabook: cherryview-pinctrl INT33FF:01: interrupt-line 0 is used by both pin 49 and pin 56 cherryview-pinctrl INT33FF:01: changing the interrupt line for pin 56 to 7 Note commit 9747070c11d6 ("Input: axp20x-pek - always register interrupt handlers") was added as a work around for the power button not being able to wakeup the system. This relies on using the PMIC's connection to the power button but that only works on systems with the AXP288 PMIC. Once this fix has been merged that workaround can be removed.

2021-11-26pinctrl: cherryview: Don't use selection 0 to mark an interrupt line as unusedHans de Goede1-2/+16
The selection 0 is a perfectly valid, so stop using it to have the special meaning of interrupt line not used in the intr_lines. Instead introduce a special CHV_INVALID_HWIRQ value, derived from INVALID_HWIRQ. which is never a valid selection and use that to indicate unused interrupt lines.

2021-11-23pinctrl: baytrail: Set IRQCHIP_SET_TYPE_MASKED flag on the irqchipHans de Goede1-1/+1
The byt_irq_type function ends with the IRQ masked, this means that calls to irq_set_irq_type() while the IRQ is enabled end up masking it, which is wrong. Add the IRQCHIP_SET_TYPE_MASKED flag to fix this. This will make the IRQ core call mask() + unmask() on the IRQ around a set_type() call when the IRQ is enabled at the type of the call. Note in practice irq_set_irq_type() getting called while the IRQ is enabled almost never happens. I hit this with a buggy DSDT where a wrongly active (_STA returns 0xf) I2C ACPI devices point to an IRQ already in use by an _AEI handler, leading to the irq_set_irq_type() call in acpi_dev_gpio_irq_get_by() getting called while the IRQ is enabled.

2021-11-22pinctrl: qcom: Add egpio feature supportPrasad Sodagudi2-2/+23
egpio is a scheme which allows special power Island Domain IOs (LPASS,SSC) to be reused as regular chip GPIOs by muxing regular TLMM functions with Island Domain functions. With this scheme, an IO can be controlled both by the cpu running linux and the Island processor. This provides great flexibility to re-purpose the Island IOs for regular TLMM usecases. 2 new bits are added to ctl_reg, egpio_present is a read only bit which shows if egpio feature is available or not on a given gpio. egpio_enable is the read/write bit and only effective if egpio_present is 1. Once its set, the Island IO is controlled from Chip TLMM. egpio_enable when set to 0 means the GPIO is used as Island Domain IO. To support this we add a new function 'egpio' which can be used to set the egpio_enable to 0, for any other TLMM controlled functions we set the egpio_enable to 1.
