2017-09-12pinctrl/amd: save pin registers over suspend/resumeDaniel Drake2-0/+76
The touchpad in the Asus laptop models X505BA/BP and X542BA/BP is unresponsive after suspend/resume. The following error appears during resume: i2c_hid i2c-ELAN1300:00: failed to reset device. The problem here is that i2c_hid does not notice the interrupt being generated at this point, because the GPIO is no longer configured for interrupts. Fix this by saving pinctrl-amd pin registers during suspend and restoring them at resume time. Based on code from pinctrl-intel.

2017-09-12pinctrl: armada-37xx: Fix gpio interrupt setupGregory CLEMENT1-19/+22
Since commit dc749a09ea5e ("gpiolib: allow gpio irqchip to map irqs dynamically"), the irqs for gpio are not statically allocated during in gpiochip_irqchip_add.

2017-08-31pinctrl: Add sleep related state to indicate sleep related configsBaolin Wang1-0/+2

That means some pins are not controlled by any specific driver in the OS, but need to be controlled when entering sleep mode.

2017-08-22pinctrl: intel: Disable GPIO pin interrupts in suspendRushikesh S Kadam1-0/+1
The fix prevents unintended wakes from second level GPIO pin interrupts. On some Intel Kabylake platforms, it is observed that GPIO pin interrupts can wake the platform from suspend-to-idle, even though the IRQ is not configured as IRQF_NO_SUSPEND or enable_irq_wake(). This can cause undesired wakes on Mobile devices such as Laptops and Chromebook devices. For example a headset jack insertion is not a desired wake source on Chromebook devices. The pinctrl-intel (GPIO controller) driver implements a "Shared IRQ" model. All GPIO pin interrupts are OR'ed and mapped to a first level IRQ14 (or IRQ15). The driver registers an irq_chip struct and maps an irq_domain for the GPIO pin interrupts. The IRQ14 handler demuxes and calls the second level IRQ for the respective pin. In the suspend entry flow, at suspend_noirq stage, the kernel disables IRQs that are not marked for wake. The pinctrl-intel driver does not implement a irq_disable() callback (to take advantage of lazy disabling). The pinctrl-intel GPIO interrupts are not disabled in hardware during suspend entry, and thus are able to wake the SoC out of suspend-to-idle. This patch sets the IRQCHIP_MASK_ON_SUSPEND flag for the GPIO irq_chip, to disable the second level interrupts at suspend_noirq stage via the irq_mask callbacks. The irq_mask callback disables the IRQs in hardware by programming the corresponding GPIO pad registers. Only IRQs that are not marked for wake are disabled.
