Subject: [PATCH V3 0/2] I2C: Add bus recovery infrastructure
Date: Fri, 2 Mar 2012 11:53:41 +0530 [thread overview]
Message-ID: <cover.1330669025.git.viresh.kumar@st.com> (raw)
Hello,
This patchset adds i2c bus recovery infrastructure to i2c adapters as specified
in the i2c protocol Rev. 03 section 3.16 titled "Bus clear".
http://www.nxp.com/documents/user_manual/UM10204.pdf
This patch was earlier part of a separate thread:
http://www.spinics.net/lists/linux-i2c/msg07267.html
Changes since V2:
- gpio flags are now passed from controller drivers
- added support for sda line polling
- Aligned i2c-designware driver with generic recovery support
