Subject: [PATCH v2 0/2] usb: typec: tps6598x: add reset gpio support
Date: Fri, 15 Sep 2023 14:23:47 +0200 [thread overview]
Message-ID: <20230912-topic-tps6598x_reset-v2-0-02a12e2ec50a@wolfvision.net> (raw)
The TPS6598x PD controller provides an active-high hardware reset input
that reinitializes all device settings. If it is not grounded by
design, the driver must be able to de-assert it in order to initialize
the device.
This series adds and documents the reset signal management. It also
includes the basic reset management for initialization and
suspend/resume control.
Signed-off-by: Javier Carrasco <javier.carrasco@wolfvision.net>

Changes in v2:
- core.c: minor coding style correction ({} in 'else' after 'if {}')
- ti,tps6598x.yaml: reference to the device instead of the driver in
the commit message.
- Link to v1: https://lore.kernel.org/r/20230912-topic-tps6598x_reset-v1-0-78dc0bf61790@wolfvision.net
