i2c: algos: bit: make the error messages grepable

2018-08-30T21:11:42+00:00

Yep, I went looking for one of these, and I wasn't able to find it easily. That's worse than a line which is 82-chars long, IMHO. Signed-off-by: Jan Kundrát Signed-off-by: Wolfram Sang

i2c: algos: bit: mention our experience about initial states

2018-06-29T06:19:51+00:00

So, if somebody wants to re-implement this in the future, we pinpoint to a problem case. Signed-off-by: Wolfram Sang Acked-by: Alex Deucher Signed-off-by: Wolfram Sang

Revert "i2c: algo-bit: init the bus to a known state"

2018-06-29T06:19:41+00:00

This reverts commit 3e5f06bed72fe72166a6778f630241a893f67799. As per bugzilla #200045, this caused a regression. I don't really see a way to fix it without having the hardware. So, revert the patch and I will fix the issue I was seeing originally in the i2c-gpio driver itself. I couldn't find new users of this algorithm since, so there should be no one depending on the new behaviour.

i2c: algos: make use of i2c_8bit_addr_from_msg

i2c: algo-bit: init the bus to a known state

2017-12-30T23:16:37+00:00

Ensure the bus is free when we register the adapter. Before the SCL/SDA wires were in an unknown state. It used to work because sending a byte has a retry mechanism which was triggered if the bus was initially in a non-free state. But the graceful way to do it is to initialize correctly.

i2c: algo-bit: add support for I2C_M_STOP

2017-06-23T18:45:43+00:00

Support for enforced STOPs will allow us to use SCCB compatible devices. Based on a preliminary patch by Wolfram Sang. Signed-off-by: Jean Delvare Tested-by: Wolfram Sang Signed-off-by: Wolfram Sang

i2c: algo-bit: declare i2c_bit_quirk_no_clk_stretch as static

2016-05-11T15:16:30+00:00

i2c_bit_quirk_no_clk_stretch is used in i2c-algo-bit.c only, so declare it as static. Signed-off-by: Michele Curti Signed-off-by: Wolfram Sang

i2c: algo-bit: add I2C_AQ_NO_CLK_STRETCH

2015-11-30T17:37:25+00:00

Add I2C_AQ_NO_CLK_STRETCH to drivers/i2c/algos/i2c-algo-bit.c when getscl is not available. Signed-off-by: Nicola Corna Signed-off-by: Wolfram Sang

i2c: remove FSF address

2014-11-07T17:35:33+00:00

We have a central copy of the GPL for that. Some addresses were already outdated. Signed-off-by: Wolfram Sang
