Two separate de-init functions are merged into one common function.
 And it is used in err_post_init of lp55xx_init_device().

22ebeb488b leds-lp55xx: clean up init function
lp5521/5523_init_device() are replaced with lp55xx common function,
 lp55xx_init_device().

 Error handler in init_device:
 deinit function are matched with 'err_post_init' section in
 lp55xx_init_device().

 Remove LP5523 engine intialization code:
 Engine functionality is not mandatory but optional.
 Moreover engine initialization is done internally with device reset command.
 Therefore, this code is unnecessary.

ffbdccdbba leds-lp55xx: use lp55xx common init function - post int
LP5521/5523 chip configuration is replaced with lp55xx common function,
 lp55xx_post_init_device().

 Name change:
 lp5521/5523_configure() to lp5521/5523_post_init_device()
 These are called in init function.

 Register access function
 Argument type is changed from 'i2c_client' to 'lp55xx_chip'.
 Use exported R/W functions of lp55xx common driver.

 Temporary variables in lp5521/5523_init_device()
 These functions will be removed but temporary variables are needed for
 blocking build warnings - incompatible pointer.

632418bf65 leds-lp5523: clean up lp5523_configure()
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.

9448217403 leds-lp5521: clean up lp5521_configure()
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.

c93d08fa75 leds-lp55xx: add new common driver for lp5521/5523
This patch supports basic common driver code for LP5521, LP5523/55231 devices.

 ( 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.
 This structure is derived from leds-lp5521.h and leds-lp5523.h

f6c64c6fc8 leds-lp55xx: do chip specific configuration on device init
Chip specific function is configured when the device is initialized.
 So _configure() is moved to each device init function.

 If chip configuration gets failed, the device is de-initialized in
 each _init_device(), not probe().

 For compile error fix, function type declarations are added.

To make _probe() simple, device initialization code is moved to
 _init_device() at each driver.
 This patch is a preceding step for lp55xx common driver architecture.

 leds-lp5521:
 When 'lp5521_init_device()' gets failed, error handling should be 'fail1'
 rather than 'fail2'.
   fail1: releasing platform resource and return code
   fail2: releasing allocated LED devices with handling 'fail1'
 The 'lp5521_init_device()' is called before creating LED devices.
 Thus, 'goto fail1' is proper error handler of this function.

I spent a few minutes to understand why the code catching the mismatch case
by checking if k is 0 or not. And the code using "k - 1" as array index is
unusual.

This patch checks acceptable rate from the lowest rate, and then we don't need
to subtract k by 1. This change improves the readability.

a1932edf8b leds-lp8788: fix a parent device in _probe()
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.

08541cbcc7 leds: leds-pwm: Add device tree bindings
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.

For usage see:

2d7c22f67d leds: leds-gpio: set devm_gpio_request_one() flags param correctly
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.

cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.

2f05e1d445 leds: leds-lp5521: return an error code on error in probe()
If "buf" wasn't equal to LP5521_REG_R_CURR_DEFAULT the probe fails but
we still return zero.  I've changed it to print an error message and
return -EINVAL.
