pinctrl: amd: fix npins for uart0 in kerncz_groups

2020-07-31T14:44:01Z

[ Upstream commit 69339d083dfb7786b0e0b3fc19eaddcf11fabdfb ] uart0_pins is defined as: static const unsigned uart0_pins[] = {135, 136, 137, 138, 139}; which npins is wronly specified as 9 later { .name = "uart0", .pins = uart0_pins, .npins = 9, }, npins should be 5 instead of 9 according to the definition.

pinctrl/amd: save pin registers over suspend/resume

2017-09-27T12:39:19Z

commit 79d2c8bede2c93f9432d7da0bc2f76a195c90fc0 upstream. 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.
