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" CC: Sekhar Nori <[email protected]> CC: Kevin Hilman <[email protected]> CC: Santosh Shilimkar <[email protected]> CC: Murali Karicheri <[email protected]> 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 drivers/i2c/busses/i2c-davinci.c | 196 ++++++++++++++++++++++-------- drivers/i2c/i2c-core.c | 4 +- include/linux/i2c.h | 4 +- include/linux/platform_data/i2c-davinci.h | 1 + 4 files changed, 148 insertions(+), 57 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
