I2C: OMAP: correct SYSC register offset for OMAP4

2012-01-26T01:25:01Z

commit 2727b1753934e154931d6b3bdf20c9b2398457a2 upstream. Correct OMAP_I2C_SYSC_REG offset in omap4 register map. Offset 0x20 is reserved and OMAP_I2C_SYSC_REG has 0x10 as offset.

i2c: Fix error value returned by several bus drivers

2012-01-26T01:24:45Z

commit 7c1f59c9d5caf3a84f35549b5d58f3c055a68da5 upstream. When adding checks for ACPI resource conflicts to many bus drivers, not enough attention was paid to the error paths, and for several drivers this causes 0 to be returned on error in some cases. Fix this by properly returning a non-zero value on every error. Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

i2c-algo-bit: Generate correct i2c address sequence for 10-bit target

i2c/pca954x: Initialize the mux to disconnected state

2011-06-29T09:36:11Z

pca954x power-on default is channel 0 connected. If multiple pca954x muxes are connected to the same physical I2C bus, the parent bus will see channel 0 devices behind both muxes by default. This is bad. Scenario: -- pca954x @ 0x70 -- ch 0 (I2C-bus-101) -- EEPROM @ 0x50 | I2C-bus-1 --- | -- pca954x @ 0x71 -- ch 0 (I2C-bus-111) -- EEPROM @ 0x50 1. Load I2C bus driver: creates I2C-bus-1 2. Load pca954x driver: creates virtual I2C-bus-101 and I2C-bus-111 3. Load eeprom driver 4. Try to read EEPROM @ 0x50 on I2C-bus-101. The transaction will also bleed onto I2C-bus-111 because pca954x @ 0x71 channel 0 is connected by default. Fix: Initialize pca954x to disconnected state in pca954x_probe() Signed-off-by: Petri Gynther Signed-off-by: Jean Delvare Cc: stable@kernel.org

i2c-bfin-twi: abort transfer is MEM bit is reset unexpectedly

2011-06-27T22:06:48Z

Sometimes, the first I2C transmit interrupt is not serviced in time (like when higher priority interrupts take too long). Since the RESTART bit is not set before the next I2C clock, when the TWI handler is finally called, the I2C session is aborted (MEM bit is reset) and both SMITSERV and MCOMP int status bits are set. So when this happens, abort the transfer. Reported-by: Isabelle Leonardi Signed-off-by: Sonic Zhang Signed-off-by: Mike Frysinger Signed-off-by: Ben Dooks
