This series contains some fixes and improvements for Davinci I2C: patch 1 - small improvement patch 2 - fixes "Bus busy" state for some case (was reported long time ago:() patch 3-5 - 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 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" Link on 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> Grygorii Strashko (5): i2c: i2c-davinci: switch to use platform_get_irq i2c: davinci: query STP always when NACK is received 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 | 205 +++++++++++++++------ drivers/i2c/i2c-core.c | 4 +- include/linux/i2c.h | 4 +- include/linux/platform_data/i2c-davinci.h | 1 + 5 files changed, 159 insertions(+), 58 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
