2018-01-08leds: lp8860: Various fixes to align with LED frameworkDan Murphy1-8/+5
Update the driver to conform with the LED framework: - use devm_led_classdev_register - destroy mutex on exit - remove dependency on CONFIG_OF in the driver and move to the Kconfig - update the MODULE_LICENSE to GPL v2 - remove setting of MAX brightness as the LED framework does this.

2018-01-08leds: lp8860: Add DT parsing to retrieve the trigger nodeDan Murphy1-0/+4
Add the ability to parse the DT and set the default trigger mode for the LED. Signed-off-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>
2018-01-08leds: lp8860: Update the dt parsing for LED labelingDan Murphy1-11/+12
Update the DT parsing for the label node so that the label is retrieved from the device child as opposed to being part of the parent. This will align this driver with the LED binding documentation Documentation/devicetree/bindings/leds/common.txt Signed-off-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>
2018-01-08leds: lp8860: Add regulator enable during initDan Murphy1-1/+23
Add the regulator enable call during initialization. If init fails then disable the regulator. Also during init the gpio gets set low even on a passing case so add if everything passes then return.

2016-01-04leds: lp8860: Remove work queueAndrew Lunn1-20/+7
Now the core implements the work queue, remove it from the drivers, and switch to using brightness_set_blocking op. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Acked-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
2015-08-28leds: lp8860: Constify reg_default tablesAxel Lin1-2/+2
These reg_default tables are not modified after initialized, so make them const. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>

2015-03-03leds: lp8860: make use of devm_gpiod_get_optionalUwe Kleine-König1-5/+7
The probe function open coded a bad variant of devm_gpiod_get_optional using devm_gpiod_get and just ignoring all errors. In contrast to that devm_gpiod_get_optional returns NULL if there was no corresponding gpio specified in the device tree (or ACPI table) and fails if there is an error (or GPIOLIB is not enabled). Moreover since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output which allows some simplification.
