Subject: [PATCH 1/2 v6] iio: light: Add DT bindings for GP2AP002
Date: Sun, 26 Jan 2020 16:05:47 +0100 [thread overview]
Message-ID: <20200126150548.9168-1-linus.walleij@linaro.org> (raw)
This adds device tree bindings for the GP2AP002 light
and proximity sensor.
As with other early proximity sensors (~2010) the light
sensor and proximity sensors were combined into a single
component.

ChangeLog v5->v6:
- Resending with v6 of the driver.
ChangeLog v4->v5:
- Collected Rob's Reviewed-by tag.
ChangeLog v3->v4:
- Resend with the changes in the main patch.
ChangeLog v1->v3:
- Drop the maxitems on the supplies, it is already 1
- Drop quotes around "alsout"
- Limit the sharp hysteresis to 8 bits as it should be
- Use /bits/ 8 in the example so it is correct
