leds: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

i2c: Make remove callback return void

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

leds: is31fl32xx: Improve error reporting in .remove()

Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't make
a difference. The device goes away anyhow and the devm cleanups are
called.

So instead of triggering the generic i2c error message, emit a more helpful
message if a problem occurs and return 0 to suppress the generic message.

This patch is a preparation for making i2c remove callbacks return void.

leds: parse linux,default-trigger DT property in LED core

Do the parsing of `linux,default-trigger` DT property to LED core.
Currently it is done in many different drivers and the code is repeated.

This patch removes the parsing from 23 drivers:
an30259a, aw2013, bcm6328, bcm6358, cr0014114, el15203000, gpio,
is31fl32xx, lm3532, lm36274, lm3692x, lm3697, lp50xx, lp8860, lt3593,
max77650, mt6323, ns2, pm8058, pwm, syscon, tlc591xx and turris-omnia.

There is one driver in drivers/input which parses this property on it's
own. I shall send a separate patch there after this is applied.

There are still 8 drivers that parse this property on their own because
they do not pass the led_init_data structure to the registering
function. I will try to refactor those in the future.

leds: leds-is31fl32xx: Replace zero-length array with flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
int stuff;
struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

leds: is31fl32xx: Use struct_size() helper

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct is31fl32xx_priv {
...
struct is31fl32xx_led_data leds[0];
};

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

So, replace the following function:

static inline size_t sizeof_is31fl32xx_priv(int num_leds)
{
return sizeof(struct is31fl32xx_priv) +
(sizeof(struct is31fl32xx_led_data) * num_leds);
}

with:

struct_size(priv, leds, count)

This code was detected with the help of Coccinelle.

leds: Add driver for the ISSI IS31FL32xx family of LED controllers

The IS31FL32xx family of LED controllers are I2C devices with multiple
constant-current channels, each with independent 256-level PWM control.

Datasheets: http://www.issi.com/US/product-analog-fxled-driver.shtml

This has been tested on the IS31FL3236 and IS31FL3216, on an ARM
(TI am335x) platform.

The programming paradigm of these devices is similar in the following
ways:
- All registers are 8 bit
- All LED control registers are write-only
- Each LED channel has a PWM register (0-255)
- PWM register writes are shadowed until an Update register is poked
- All have a concept of Software Shutdown, which disables output

However, there are some differences in devices:
- 3236/3235 have a separate Control register for each LED,
(3218/3216 pack the enable bits into fewer registers)
- 3236/3235 have a per-channel current divisor setting
- 3236/3235 have a Global Control register that can turn off all LEDs
- 3216 is unique in a number of ways
- OUT9-OUT16 can be configured as GPIOs instead of LED controls
- LEDs can be programmed with an 8-frame animation, with
programmable delay between frames
- LEDs can be modulated by an input audio signal
- Max output current can be adjusted from 1/4 to 2x globally
- Has a Configuration register instead of a Shutdown register

This driver currently only supports the base PWM control function
of these devices. The following features of these devices are not
implemented, although it should be possible to add them in the future:
- All devices are capable of going into a lower-power "software
shutdown" mode.
- The is31fl3236 and is31fl3235 can reduce the max output current
per-channel with a divisor of 1, 2, 3, or 4.
- The is31fl3216 can use some LED channels as GPIOs instead.
- The is31fl3216 can animate LEDs in hardware.
- The is31fl3216 can modulate LEDs according to an audio input.
- The is31fl3216 can reduce/increase max output current globally.

There is one driver in drivers/input which parses this property on it's
own. I shall send a separate patch there after this is applied.

There are still 8 drivers that parse this property on their own because
they do not pass the led_init_data structure to the registering
function. I will try to refactor those in the future.

leds: is31fl32xx: use struct led_init_data when registering

By using struct led_init_data when registering we do not need to parse
`label` DT property. Moreover `label` is deprecated and if it is not
present but `color` and `function` are, LED core will compose a name
from these properties instead.

leds: various: use only available OF children

Various drivers count and iterate over OF children nodes via
of_get_child_count and for_each_child_of_node. Instead they should use
of_get_available_child_count and for_each_available_child_of_node, so
that if a given node has the `status` property set to `disabled`, the
child will be ignored.
