leds-lp55xx: support firmware interface This patch provides additional device attributes which enable loading the firmware. ('select_engine' and 'run_engine') To run a LED pattern, two parts of driver should be enabled. Common features : lp55xx-common =============================== Firmware interface for loading LED patterns Chip specific features : leds-lp5521, leds-lp5523 ================================================= Register addresses for loading firmware data Register addresses for running selected engine Pattern programming sequence ============================ LP55xx chips have three program engines. To load and run a LED pattern, the programming sequence is as follows. (1) Select an engine number (1/2/3) (2) Set engine mode to load (3) Write pattern data into selected area (4) Set engine mode to run This sequence is almost same as the firmware interface. (1) Select an engine number : 'select_engine' dev attribute (2) Mode change to load : 'loading' of firmware class (3) Write pattern data into selected area : 'data' of firmware class (4) Mode change to run : 'run_engine' dev attribute (1) and (4) are device specific features which provide callback functions (2) and (3) are common features. For example, echo 1 or 2 or 3 > /sys/bus/i2c/devices/xxxx/select_engine echo 1 > /sys/class/firmware/lp5521/loading echo "4000600040FF6000" > /sys/class/firmware/lp5521/data echo 0 > /sys/class/firmware/lp5521/loading echo 1 > /sys/bus/i2c/devices/xxxx/run_engine As soon as 'loading' is set to 0, registered callback is called. Inside the callback, the selected engine is loaded and memory is updated. To run programmed pattern, 'run_engine' attribute should be enabled. Device specific data structure ============================== o Firmware callback load selected engine and update program memory o Run engine change the engine mode o 'engine_idx' and firmware data, 'fw' Those are used in the driver internally with callback functions Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>

comment "LED Triggers"
source "drivers/leds/trigger/Kconfig"
leds: add new transient trigger for one shot timer activation The leds timer trigger does not currently have an interface to activate a one shot timer. The current support allows for setting two timers, one for specifying how long a state to be on, and the second for how long the state to be off. The delay_on value specifies the time period an LED should stay in on state, followed by a delay_off value that specifies how long the LED should stay in off state. The on and off cycle repeats until the trigger gets deactivated. There is no provision for one time activation to implement features that require an on or off state to be held just once and then stay in the original state forever. Without one shot timer interface, user space can still use timer trigger to set a timer to hold a state, however when user space application crashes or goes away without deactivating the timer, the hardware will be left in that state permanently. As a specific example of this use-case, let's look at vibrate feature on phones. Vibrate function on phones is implemented using PWM pins on SoC or PMIC. There is a need to activate one shot timer to control the vibrate feature, to prevent user space crashes leaving the phone in vibrate mode permanently causing the battery to drain. This trigger exports three properties, activate, state, and duration When transient trigger is activated these properties are set to default values. - duration allows setting timer value in msecs. The initial value is 0. - activate allows activating and deactivating the timer specified by duration as needed. The initial and default value is 0. This will allow duration to be set after trigger activation. - state allows user to specify a transient state to be held for the specified duration.
