Hi, This patchset adds bus recovery functionality to Exynos HSI2C, it is used in case of transmission timeouts. Internal tests shows that it significantly improves I2C transmissions. Andi, could you take a look at it/test, feedback welcome. Later, I will post also patches to MHL chip which uses this functionality. MHL chip has known bug of being in incorrect state after hard reset, I2C bus recovery cures it. Regards Andrzej Andrzej Hajda (3): i2c: exynos5: change internal transmission timeout to 100ms i2c: exynos5: implement bus recovery functionality i2c: exynos5: do not check TRANS_STATUS in case of Exynos7 variant drivers/i2c/busses/i2c-exynos5.c | 52 +++++++++++++++++++++++++++++++++------- 1 file changed, 44 insertions(+), 8 deletions(-) -- 2.15.0
