Subject: [PATCH v3 0/3] i2c: designware: select gpio/default pin when prepare/unprepare recovery
Date: Mon, 17 Sep 2018 11:26:33 +0800 [thread overview]
Message-ID: <20180917112633.252c591c@xhacker.debian> (raw)
On some platforms, the sda/scl pins are muxed with gpio functions, so
they could be used for recovery. Select the gpio/default pin function
when prepare/unprepare recovery.
patch1 adds the missing scl-gpios, sda-gpios properties binding doc.
patch2 adds the pintrl property for i2c bus recovery.
patch3 selects gpio/default pin when prepare/unprepare recovery.
Since v2:
- add missing property dt-binding
Since v1:
- use IS_ERR_OR_NULL
Jisheng Zhang (3):
dt-bindings: i2c: designware: add optional gpio recovery properties
dt-bindings: i2c: designware: add optional pinctrl for bus recovery
i2c: designware: select gpio/default pin when prepare/unprepare
recovery
