if the SCP firmware does not respond within a specified timeout. In this

Remove the ad-hoc coreboot table search. Now the driver will only be
probed when the necessary coreboot table entry has already been found.
Furthermore, since the coreboot bus takes care of creating the device, a

The binding of R_INTC was updated to allow specifying interrupts other
than the external NMI, since routing those interrupts through the R_INTC
driver allows using them for wakeup.
Update the device trees to use the new binding.

The H3 and H5 SoCs have an additional interrupt controller in the RTC
power domain that can be used to enable wakeup for certain IRQs.
Add a node for it.

- Only add wakeup capability if "wakeup-source" is present
- Warn but do not error out if setting the wake IRQ fails
- Add "wakeup-source" property to PinePhone device tree
Ondrej Jirman (1):
input: sun4i-lradc-keys - Add wakup support
Samuel Holland (2):
PinePhone volume keys are connected to the LRADC in the A64. Users may
want to use them to wake the device from sleep. Support this by
declaring the LRADC as a wakeup source.

The LRADC provides an interrupt that can be used to wake the system.
Signify this by accepting a "wakeup-source" property in the binding.

This series cleans up some dead code in the sunxi-cir driver and adds
system power management hooks.
Samuel Holland (4):

Only one register, SUNXI_IR_CIR_REG, is accessed from outside the
interrupt handler, and that register is not accessed from inside it.
As there is no overlap between different contexts, no lock is needed.
