Subject: [PATCH v5 3/3] Documentation: power: rt9471: Document exported sysfs entries
Date: Thu, 15 Sep 2022 00:30:15 +0800 [thread overview]
Message-ID: <1663173015-7934-4-git-send-email-u0084500@gmail.com> (raw)
In-Reply-To: <1663173015-7934-1-git-send-email-u0084500@gmail.com>
From: ChiYuan Huang <cy_huang@richtek.com>
Document the settings exported by rt9471 charger driver through sysfs entries:
- sysoff_enable
- port_detect_enable
Signed-off-by: ChiYuan Huang <cy_huang@richtek.com>
---
Since v5:
- Recover all the change in sysfs-class-power.
- New a sysfs-class-power-rt9471 file.
- Remove 'charge_term_enable' sysfs entry, directly integrate it in
'charge_term_current' power supply property control.
