linux.git/drivers/pinctrl, branch v4.14-rc4 Linux kernel source tree pinctrl/amd: save pin registers over suspend/resume 2017-09-12T13:58:45+00:00 Daniel Drake drake@endlessm.com 2017-09-11T06:11:56+00:00 79d2c8bede2c93f9432d7da0bc2f76a195c90fc0 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.

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.

Since commit dc749a09ea5e ("gpiolib: allow gpio irqchip to map irqs
dynamically"), the irqs for gpio are not statically allocated during in
gpiochip_irqchip_add.

This driver was based on this assumption for initializing the mask
associated to each interrupt this led to a NULL pointer crash in the
kernel:
