Staging: iio: adc: ad7816: fix symbolic permissions coding style issue

2017-01-28T12:22:07+00:00

Octal permissions should be used instead of symbolic ones for easier reading. Signed-off-by: Julián de Gortari Signed-off-by: Jonathan Cameron

iio: trigger: free trigger resource correctly

2017-01-22T16:14:21+00:00

These stand-alone trigger drivers were using iio_trigger_put() where they should have been using iio_trigger_free(). The iio_trigger_put() adds a module_put which is bad since they never did a module_get. In the sysfs driver, module_get/put's are used as triggers are added & removed. This extra module_put() occurs on an error path in the probe routine (probably rare). In the bfin-timer & interrupt trigger drivers, the module resources are not explicitly managed, so it's doing a put on something that was never get'd. It occurs on the probe error path and on the remove path (not so rare). Tested with the sysfs trigger driver. The bfin & interrupt drivers were build tested & inspected only.

staging: iio: isl29028: add runtime power management support

2017-01-22T13:21:40+00:00

This patch adds runtime power management support to the isl29028 driver. It defaults to powering off the device after two seconds of inactivity. isl29028_chip_init_and_power_on() currently only zeros the CONFIGURE register on the chip, which will cause the chip to turn off. This patch also renames that function to isl29028_clear_configure_reg() since it is now used in several places. Signed-off-by: Brian Masney Signed-off-by: Jonathan Cameron

staging: iio: isl29028: only set ALS scale when ALS/IR sensing is enabled

2017-01-22T13:21:39+00:00

isl29028_chip_init_and_power_on() calls isl29028_set_als_scale() and this is not needed until the user actually needs to take a reading from the ALS/IR sensor. This patch moves the isl29028_set_als_scale() call from isl29028_chip_init_and_power_on() to isl29028_set_als_ir_mode(). This sets the stage for faster resume times from runtime power management if the user is only querying the proximity sensor. Signed-off-by: Brian Masney Signed-off-by: Jonathan Cameron

staging: iio: isl29028: only set proximity sampling rate when proximity is enabled

2017-01-22T13:21:38+00:00

isl29028_chip_init_and_power_on() calls isl29028_set_proxim_sampling() and this is not needed until the user actually needs to take a proximity reading. This patch moves the isl29028_set_proxim_sampling() call from isl29028_chip_init_and_power_on() to isl29028_enable_proximity(). This sets the stage for faster resume times from the runtime power management if the user is only querying the ALS/IR sensor. Signed-off-by: Brian Masney Signed-off-by: Jonathan Cameron

staging: iio: isl29028: remove enable flag from isl29028_enable_proximity()

2017-01-22T13:21:38+00:00

isl29028_enable_proximity() has a boolean argument named enable. This function is only called once and the enable flag is set to true in that call. This patch removes the enable parameter from that function. Signed-off-by: Brian Masney Signed-off-by: Jonathan Cameron

staging: iio: isl29028: remove unnecessary parenthesis

2017-01-22T13:21:37+00:00

isl29028_write_raw() contains unnecessary parenthesis when checking to see if the passed in lux scale is valid. This patch removes the unnecessary parenthesis. Signed-off-by: Brian Masney Signed-off-by: Jonathan Cameron

staging: iio: isl29028: remove out of memory log message

2017-01-22T13:21:37+00:00

If the call to devm_iio_device_alloc() fails, then isl29028_probe() logs a message saying that memory cannot be allocated. The user's system most likely has larger issues at this point. This patch removes that error message since the error code is passed on and the message is not necessary. Signed-off-by: Brian Masney Signed-off-by: Jonathan Cameron

staging: iio: isl29028: remove unnecessary error logging in isl29028_chip_init_and_power_on()

2017-01-22T13:21:36+00:00

If the call to isl29028_chip_init_and_power_on() in isl29028_probe() fails, then isl29028_probe() will log an error message. All of the error paths in that call path already have error logging in place. This patch removes the unnecessary logging. Signed-off-by: Brian Masney Signed-off-by: Jonathan Cameron
