* TI LP5562 LED Driver
|

|
|

Author: Milo(Woogyom) Kim <milo.kim@ti.com>
|
||||||
|
|
||||||
|
Description
|
||||||
|
|
||||||
|
LP5562 can drive up to 4 channels. R/G/B and White.
|
||||||
|
LEDs can be controlled directly via the led class control interface.
|
||||||
|
|
||||||
|
All four channels can be also controlled using the engine micro programs.
|
||||||
|
LP5562 has the internal program memory for running various LED patterns.
|
||||||
|
For the details, please refer to 'firmware' section in leds-lp55xx.txt
|
||||||
|
|
||||||
|
Device attribute: engine_mux
|
||||||
|
|
||||||
|
3 Engines are allocated in LP5562, but the number of channel is 4.
|
||||||
|
Therefore each channel should be mapped to the engine number.
|
||||||
|
Value : RGB or W
|
||||||
|
|
||||||
|
This attribute is used for programming LED data with the firmware interface.
|
||||||
|
Unlike the LP5521/LP5523/55231, LP5562 has unique feature for the engine mux,
|
||||||
|
so additional sysfs is required.
|
||||||
|
|
||||||
|
LED Map
|
||||||
|
Red ... Engine 1 (fixed)
|
||||||
|
Green ... Engine 2 (fixed)
|
||||||
|
Blue ... Engine 3 (fixed)
|
||||||
|
White ... Engine 1 or 2 or 3 (selective)
|
||||||
|
|
||||||
|
How to load the program data using engine_mux
|
||||||
|
|
||||||
|
Before loading the LP5562 program data, engine_mux should be written between
|
||||||
|
the engine selection and loading the firmware.
|
||||||
|
Engine mux has two different mode, RGB and W.
|
||||||
|
RGB is used for loading RGB program data, W is used for W program data.
|
||||||
|
|
||||||
|
For example, run blinking green channel pattern,
|
||||||
|
echo 2 > /sys/bus/i2c/devices/xxxx/select_engine # 2 is for green channel
|
||||||
|
echo "RGB" > /sys/bus/i2c/devices/xxxx/engine_mux # engine mux for RGB
|
||||||
|
echo 1 > /sys/class/firmware/lp5562/loading
|
||||||
|
echo "4000600040FF6000" > /sys/class/firmware/lp5562/data
|
||||||
|
echo 0 > /sys/class/firmware/lp5562/loading
|
||||||
|
echo 1 > /sys/bus/i2c/devices/xxxx/run_engine
|
||||||
|
|
||||||
|
To run a blinking white pattern,
|
||||||
|
echo 1 or 2 or 3 > /sys/bus/i2c/devices/xxxx/select_engine
|
||||||
|
echo "W" > /sys/bus/i2c/devices/xxxx/engine_mux
|
||||||
|
echo 1 > /sys/class/firmware/lp5562/loading
|
||||||
|
echo "4000600040FF6000" > /sys/class/firmware/lp5562/data
|
||||||
|
echo 0 > /sys/class/firmware/lp5562/loading
|
||||||
|
echo 1 > /sys/bus/i2c/devices/xxxx/run_engine
|
||||||
|
|
||||||
|
How to load the predefined patterns
|
||||||
|
|
||||||
|
Please refer to 'leds-lp55xx.txt"
|
||||||
|
|
||||||
|
Setting Current of Each Channel
|
||||||
|
|
||||||
|
Like LP5521 and LP5523/55231, LP5562 provides LED current settings.
|
||||||
|
The 'led_current' and 'max_current' are used.
|
||||||
|
|
||||||
|
(Example of Platform data)
|
||||||
|
|
||||||
|
To configure the platform specific data, lp55xx_platform_data structure is used.
|
||||||
|
|
||||||
|
static struct lp55xx_led_config lp5562_led_config[] = {

||||||

|
||||||

|
||||||
|
.enable = lp5562_enable,
|
||||||
|
};
|
||||||
|
|
||||||
|
If the current is set to 0 in the platform data, that channel is
|
||||||
|
disabled and it is not visible in the sysfs.

( Predefined pattern data )
|
||||||
|
|
||||||
|
Without the firmware interface, LP55xx driver provides another method for
|
||||||
|
loading a LED pattern. That is 'predefined' pattern.
|
||||||
|
A predefined pattern is defined in the platform data and load it(or them)
|
||||||
|
via the sysfs if needed.
|
||||||
|
To use the predefined pattern concept, 'patterns' and 'num_patterns' should be
|
||||||
|
configured.
|
||||||
|
|
||||||
|
Example of predefined pattern data:
|
||||||
|
|
||||||
|
/* mode_1: blinking data */
|
||||||
|
static const u8 mode_1[] = {
|
||||||
|
0x40, 0x00, 0x60, 0x00, 0x40, 0xFF, 0x60, 0x00,
|
||||||
|
};
|
||||||
|
|
||||||
|
/* mode_2: always on */
|
||||||
|
static const u8 mode_2[] = { 0x40, 0xFF, };
|
||||||
|
|
||||||
|
struct lp55xx_predef_pattern board_led_patterns[] = {
|
||||||
|
{
|
||||||
|
.r = mode_1,
|
||||||
|
.size_r = ARRAY_SIZE(mode_1),
|
||||||
|
},
|
||||||
|
{
|
||||||
|
.b = mode_2,
|
||||||
|
.size_b = ARRAY_SIZE(mode_2),
|
||||||
|
},
|
||||||
|
}
|
||||||
|
|
||||||
|
struct lp55xx_platform_data lp5562_pdata = {
|
||||||
|
...
|
||||||
|
.patterns = board_led_patterns,
|
||||||
|
.num_patterns = ARRAY_SIZE(board_led_patterns),
|
||||||
|
};
|
||||||
|
|
||||||
|
Then, mode_1 and mode_2 can be run via through the sysfs.
|
||||||
|
|
||||||
|
echo 1 > /sys/bus/i2c/devices/xxxx/led_pattern # red blinking LED pattern
|
||||||
|
echo 2 > /sys/bus/i2c/devices/xxxx/led_pattern # blue LED always on
|
||||||
|
|
