| * leds-lp55xx: use lp55xx common init function - detectMilo(Woogyom) Kim2013-02-064-49/+39
| | | | | | | | | | | | | | | | | | | | LP5521/5523 chip detection functions are replaced with lp55xx common function, lp55xx_detect_device(). Chip dependent address and values are configurable in each driver. In init function, chip detection is executed.

| | | | | | | | | | | | | | | | | | | | LP5521/5523 reset device functions are moved to lp55xx common driver. Value of register address and value are chip dependent.

| * leds-lp5523: clean up lp5523_configure()Milo(Woogyom) Kim2013-02-061-58/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a preceding step for making common lp55xx init function. Return code: Do not use 'OR' arithmetic for the result. If some error occurs, just return it. Remove engine verification code: To check whether internal engine works or not, many lines of code are executed. However, this job is unnecessary during the chip initialization because the engine usage is not mandatory but optional function. LED engines are enabled when specific LED pattern is loaded. Therefore, this verification code is removed. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
| * leds-lp5521: clean up lp5521_configure()Milo(Woogyom) Kim2013-02-061-40/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a preceding step for making common lp55xx init function. LP5521_REG_R_CURRENT register code moved: Chip specific code moved from lp5521_init_device() to lp5521_configure(). Remove engine init function: LP5521 has internal program engines which are used for running LED patterns. (blinking, ramp up/down and other emotional visual effects) Engine initialization is done by reset command in lp5521_init_device(). Remove this duplicate code. Return code: Do not use 'OR' arithmetic for the result. If some error occus, just return it. Enable latency: Use explicit named function, lp5521_wait_enable_done(). According to the datasheet, 500us is guaranteed time. Thus wait time is changed from 1000us to 500us. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>

( Driver Structure Data ) lp55xx_led and lp55xx_chip In lp55xx common driver, two different data structure is used. o lp55xx_led control multi output LED channels such as led current, channel index. o lp55xx_chip general chip control such like the I2C and platform data. For example, LP5521 has maximum 3 LED channels. LP5523/55231 has 9 output channels. lp55xx_chip for LP5521 ... lp55xx_led #1 lp55xx_led #2 lp55xx_led #3 lp55xx_chip for LP5523 ... lp55xx_led #1 lp55xx_led #2 . . lp55xx_led #9 ( Platform Data ) LP5521 and LP5523/55231 have own specific platform data. However, this data can be handled with just one platform data structure. The lp55xx platform data is declared in the header.

| | | | | | | | | | | | | | | | | | | | | | | | | | The lp8788-keyled is a platform driver of lp8788-mfd. The platform device is allocated when mfd_add_devices() is called in lp8788-mfd. On the other hand, 'lp->dev' is the i2c client device. Therefore, this 'platform_device' is a proper parent device in case of resource managed mem alloc, registering led device and device kernel messages.

| * leds: leds-pwm: Add device tree bindingsPeter Ujfalusi2013-02-011-20/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DT binding for the pwm-leds devices are similar to the gpio-leds type. LEDs are represented as sub-nodes of the pwm-leds device. The code for handling the DT boot is based on the code found in the leds-gpio driver and adapted to use PWMs instead of GPIOs. To avoid having custom cleanup code in case of DT boot the newly created devm_of_pwm_get() API is used to get the correct PWM instance.

* leds: leds-gpio: set devm_gpio_request_one() flags param correctlyJavier Martinez Canillas2013-01-021-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit a99d76f leds: leds-gpio: use gpio_request_one changed the leds-gpio driver to use gpio_request_one() instead of gpio_request() + gpio_direction_output() Unfortunately, it also made a semantic change that breaks the leds-gpio driver. The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | (led_dat->active_low ^ state) Since GPIOF_DIR_OUT is 0, the final flags value will just be the XOR'ed value of led_dat->active_low and state. This value were used to distinguish between HIGH/LOW output initial level and call gpio_direction_output() accordingly. With this new semantic gpio_request_one() will take the flags value of 1 as a configuration of input direction (GPIOF_DIR_IN) and will call gpio_direction_input() instead of gpio_direction_output(). int gpio_request_one(unsigned gpio, unsigned long flags, const char *label) { .. if (flags & GPIOF_DIR_IN) err = gpio_direction_input(gpio); else err = gpio_direction_output(gpio, (flags & GPIOF_INIT_HIGH) ? 1 : 0); .. } The right semantic is to evaluate led_dat->active_low ^ state and set the output initial level explicitly.
