Subject: [PATCH v3 3/3] dt-bindings: mfd: max8998: Add charger subnode binding
Date: Tue, 17 Jul 2018 18:05:09 +0200 [thread overview]
Message-ID: <1531843509-3533-4-git-send-email-pawel.mikolaj.chmiel@gmail.com> (raw)
In-Reply-To: <1531843509-3533-1-git-send-email-pawel.mikolaj.chmiel@gmail.com>
This patch adds devicetree bindings documentation for
battery charging controller as the subnode of MAX8998 PMIC.
Signed-off-by: Paweł Chmiel <pawel.mikolaj.chmiel@gmail.com>

Changes from v2:
- Make charge-restart-level-microvolt optional.
- Make charge-timeout-hours optional.
Changes from v1:
- Removed unneeded Fixes tag
- Correct description of all charger values
- Added missing property unit
