* drivers/leds: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-02-271-1/+0
| | | | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

| * leds: lp5521/5523: Fix multiple engine usage bugMilo Kim2014-01-281-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever the engine is loaded by the user-application, the operation mode is reset first. But it has a problem in case of multiple engine used because previous engine settings are cleared. The driver should update not whole 8bits but each engine bit by masking. On the other hands, whole engines should be reset when the driver is unloaded and on initializing the LP5523 driver. So, new functions are used for this handling - lp5521/5523_stop_all_engines().

|/ | | | | | | | | | | | | | | It can be a problem when a pattern is loaded via the firmware interface. LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'. So it should be deleted. On the other hand, locks are required in store_engine_load() on updating program memory.

| | | | | | | | | | | | | | | This patch reduces the number of programming commands. (Count of sending commands) Old code: 32 + program size (32 counts for clearing program memory) New code: 32 Pattern buffer is initialized to 0 in this function.

* leds: lp5523: restore legacy device attributesMilo Kim2013-08-271-4/+223
| | | | | | | | | | | | | | | | | | | | | | | | | git commit db6eaf8388a413a5ee1b4547ce78506b9c6456b0 (leds-lp5523: use generic firmware interface) causes an application conflict. This interface should be maintained for compatibility. Restored device attributes are 'engineN_mode', 'engineN_load' and 'engineN_leds'. (N = 1, 2 or 3) A 'selftest' attribute macro is replaced with LP55xx common macro. Those are accessed when a LED pattern is run by an application. Use a mutex in lp5523_update_program_memory() : This function is called when an user-application writes a 'engineN_load' file or pattern data is loaded from generic firmware interface. So, writing program memory should be protected. If an error occurs on accessing this area, just it returns as -EINVAL quickly. This error code is exact same as old driver function, lp5523_do_store_load() because it should be kept for an user-application compatibility. Even the driver is changed, we can use the application without re-compiling sources.

* leds: lp5523: LED MUX configuration on initializingMilo Kim2013-08-271-1/+69
| | | | | | | | | | | | | | | | LED MUX start and stop address should be updated in the program memory on LP5523 initialization. LED pattern doesn't work without additional MUX address configuration. This handling is done by new function, lp5523_init_program_engine(). Eventually, it's called during device initialization, lp5523_post_init_device(). This is a conflict after git commit 632418bf65503405df3f9a6a1616f5a95f91db85 (leds-lp5523: clean up lp5523_configure()). So it should be fixed.

| | | | | | | | | | | | | | | | lp5523_load_engine() It is called whenever the operation mode is changed to 'load'. It is used for simple operation mode change. It will be used when engine mode and LED selection is updated in later patch. lp5523_load_engine_and_select_page() Change the operation mode to 'load' and select program page number. This is used for programming a LED pattern at a time. So load_engine() is replaced with new API, load_engine_and_select_page() in lp5523_firmware_loaded().

So each driver error handler is changed to 'err_register_leds' Chip dependency: 'brightness_work_fn' and 'set_led_current' To make the structure abstract, both functions are configured in each driver.

* leds-lp5523: turn off the LED engines on unloading the driverKim, Milo2012-09-131-0/+3
| | | | | | | | | | | The LP5523 has 3 engines which are used for running LED patterns. These engines should be off while unloading the driver. Obviously, LP5523 platform data are used for releasing the resource such like enable()/release_resource(), but these are not mandatory. Therefore this patch is required without the platform data dependency. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
* leds-lp5523: use the i2c device id rather than fixed nameKim, Milo2012-09-111-4/+6
| | | | | | | | | | LP5523 driver supports both LP5523 and LP55231. The i2c device id is one of the two - lp5523 or lp55231. So it's better to use matching i2c device id while enumerating the device and naming LED channels. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
