pinctrl: core: print gpio in pins debugfs file · f1b206cf

Drew Fustini authored Jul 22, 2020

If there is a gpio range mapping for the pin, then print out the gpio
chip and line index for the pin in the debugfs 'pins' file with the
format: "[line-index]:[gpio-label]"

Here is example output on the BeagleBoard.org PocketBeagle (AM3358):

pinctrl: stm32: use the hwspin_lock_timeout_in_atomic() API · 290a9f93

Fabien Dessenne authored Jun 15, 2020

Use the hwspin_lock_timeout_in_atomic() API which is the most appropriated
here. Indeed:
- hwspin_lock_() is called after spin_lock_irqsave()
- the hwspin_lock_timeout() API relies on jiffies count which won't work
  if IRQs are disabled which is the case here.

pinctrl: mcp23s08: Use irqchip template · 57597e15

Linus Walleij authored Jul 21, 2020

This makes the driver use the irqchip template to assign
properties to the gpio_irq_chip instead of using the
explicit calls to gpiochip_irqchip_add_nested() and
gpiochip_set_nested_irqchip(). The irqchip is instead
added while adding the gpiochip.
