This patch set contains more of my cleanups to the isl29028 light driver in preparation for moving the driver out of staging. The main feature introduced by this patch set is support for runtime power management and autosuspend after two seconds. The rest of the patches are minor code improvements, mostly style. The ALS and IR portion of the sensor was tested using an ISL29028 hooked up to a Raspberry Pi 2. In my v1 submission cover letter, I mention that I am not able to use the proximity sensing function on my sensor. (This is before any of my code changes.) I'm going to look into that issue next. I suspect that it is a hardware issue on my local setup. I verified with a visible light LED that the IRDR pin continues to be driven as expected when a proximity reading is requested and is turned off after two seconds of inactivity. The pin is driven the next time a proximity reading is requested. Datasheet: http://www.intersil.com/content/dam/Intersil/documents/isl2/isl29028.pdf Changes since version 1: - Suggestions from Jonathan Cameron - In v1 patch #4 (#15 in this series), remove suspended flag. Added support for runtime power management support and autosuspend. - Dropped v1 patch #19 (remove legacy device tree binding) - Dropped v1 patch #11 (made column alignment in isl29028_channels consistent) - In v1 patches #13 and #14, if there is an error, return inside the error check. - It was suggested to drop the v1 #2 patch that removes the enable flag from isl29028_enable_proximity(). I think that we can apply that patch now that the driver has runtime power management support. - Suggestions from Dan Carpenter - Dropped v1 patch #12 (fix comparison between signed and unsigned integers) Brian Masney (15): staging: iio: isl29028: made alignment of variables in struct isl29028_chip consistent staging: iio: isl29028: fix alignment of function arguments staging: iio: isl29028: combine isl29028_proxim_get() and isl29028_read_proxim() staging: iio: isl29028: change newlines to improve readability staging: iio: isl29028: remove unused define ISL29028_DEV_ATTR staging: iio: isl29028: move failure logging into isl29028_set_proxim_sampling() staging: iio: isl29028: move failure logging into isl29028_set_als_scale() staging: iio: isl29028: made error messages consistent staging: iio: isl29028: remove unnecessary error logging in isl29028_chip_init_and_power_on() staging: iio: isl29028: remove out of memory log message staging: iio: isl29028: remove unnecessary parenthesis staging: iio: isl29028: remove enable flag from isl29028_enable_proximity() staging: iio: isl29028: only set proximity sampling rate when proximity is enabled staging: iio: isl29028: only set ALS scale when ALS sensing is enabled staging: iio: isl29028: add runtime power management support drivers/staging/iio/light/isl29028.c | 323 ++++++++++++++++++++++++----------- 1 file changed, 221 insertions(+), 102 deletions(-) -- 2.9.3 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
