From: Grygorii Strashko <grygorii.strashko@xxxxxxxxxx> This series converts driver to use I2C bus recovery infrastructure and adds Davinci I2C bus recovery mechanizm based on using ICPFUNC registers. These patches are combination of two patches from Ben Gardiner [1] and Mike Looijmans [2] which i've reworked to use I2C bus recovery infrastructure [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2011-April/047305.html "[PATCH 0/6] i2c-davinci gpio pulsed SCL recovery with ICPFUNC" [2] https://lkml.org/lkml/2014/2/28/133 "[PATCH] i2c-davinci: Implement a bus recovery that actually works" Changes in v4: - no changes, re-besed on top of i2c/for-next, K4.1 Changes in v3: - minor comments applied Changes in v2: - patch 1: error handling improved - patch 2: commit message updated - patch 4: minor comments applied - patch 5: added new optional DT property "ti,has-pfunc" Links v3: http://www.spinics.net/lists/linux-i2c/msg17835.html v2: https://lkml.org/lkml/2014/11/26/252 v1: http://www.spinics.net/lists/linux-i2c/msg17601.html CC: Sekhar Nori <nsekhar@xxxxxx> CC: Kevin Hilman <khilman@xxxxxxxxxxxxxxxxxxx> CC: Santosh Shilimkar <ssantosh@xxxxxxxxxx> CC: Murali Karicheri <m-karicheri2@xxxxxx> CC: Alexander Sverdlin <alexander.sverdlin@xxxxxxxxx> Grygorii Strashko (3): i2c: recovery: change input parameter to i2c_adapter for prepare/unprepare_recovery i2c: davinci: use bus recovery infrastructure i2c: davinci: use ICPFUNC to toggle I2C as gpio for bus recovery .../devicetree/bindings/i2c/i2c-davinci.txt | 3 + drivers/i2c/busses/i2c-davinci.c | 177 ++++++++++++++++----- drivers/i2c/i2c-core.c | 4 +- include/linux/i2c.h | 4 +- include/linux/platform_data/i2c-davinci.h | 1 + 5 files changed, 144 insertions(+), 45 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
