i2c: algo: pca: Reapply i2c bus settings after reset

2020-09-09T08:22:40+00:00

If something goes wrong (such as the SCL being stuck low) then we need to reset the PCA chip. The issue with this is that on reset we lose all config settings and the chip ends up in a disabled state which results in a lock up/high CPU usage. We need to re-apply any configuration that had previously been set and re-enable the chip.

i2c: Use separate MODULE_AUTHOR() statements for multiple authors

2020-07-04T06:25:13+00:00

Modules with multiple authors should use multiple MODULE_AUTHOR() statements according to comment in include/linux/module.h. Split the i2c modules with multiple authors to use multiple MODULE_AUTHOR() statements. Signed-off-by: Jarkko Nikula Reviewed-by: Jean Delvare Signed-off-by: Wolfram Sang

i2c: algo-pca: Add 0x78 as SCL stuck low status for PCA9665

2020-07-04T06:17:47+00:00

The PCA9665 datasheet says that I2CSTA = 78h indicates that SCL is stuck low, this differs to the PCA9564 which uses 90h for this indication. Treat either 0x78 or 0x90 as an indication that the SCL line is stuck. Based on looking through the PCA9564 and PCA9665 datasheets this should be safe for both chips. The PCA9564 should not return 0x78 for any valid state and the PCA9665 should not return 0x90.
