Subject: [PATCH i2c-next v3 1/3] dt-bindings: i2c: aspeed: Add 'timeout' property as an optional property
Date: Wed, 26 Sep 2018 14:58:40 -0700 [thread overview]
Message-ID: <20180926215842.23125-2-jae.hyun.yoo@linux.intel.com> (raw)
In-Reply-To: <20180926215842.23125-1-jae.hyun.yoo@linux.intel.com>
This commit adds 'aspeed,timeout' property as an optional property
which can be used for setting 'timeout' value of
'struct i2c_adapter'. With this patch, the timeout value can be
set through an I2C_TIMEOUT ioctl on cdev, or through this optional
DT property.
