[PATCH v2 0/2] Correct gpio-ir-recv wakeup capability

[Florian Fainelli]

This small patch series fixes the gpio-ir-recv binding and driver to
first indicate that it can be a wake-up source for the system, and
second actually make that happen.

Changes in v2:
- corrected the indentation of the description for "wakeup-source"

[PATCH v2 1/2] dt-bindings: media: gpio-ir-receiver: Document wakeup-souce property

[Florian Fainelli]

The GPIO IR receiver can be used as a wake-up source for the system,
document that.

[PATCH v2 2/2] media: rc: gpio-ir-recv: Fix support for wake-up

[Florian Fainelli]

The driver was intended from the start to be a wake-up source for the
system, however due to the absence of a suitable call to
device_set_wakeup_capable(), the device_may_wakeup() call used to decide
whether to enable the GPIO interrupt as a wake-up source would never
happen. Lookup the DT standard "wakeup-source" property and call
device_init_wakeup() to ensure the device is flagged as being wakeup
capable.

Ping? Someone maintaining this driver?

That's me :) Applied, thanks for the reminder.
