[PATCH 0/4] leds: Add driver for the ISSI IS31FL32xx family of LED controllers

["David Rivshin (Allworx)" <drivshin.allworx-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: David Rivshin <drivshin-5fOYsn7Fw8lBDgjK7y7TUQ@public.gmane.org>

This series adds support for the ISSI IS31FL32xx family of I2C LED
controllers. Since the IS31FL3218 is actually the same device as the
SN3218, the dedicated leds-sn3218 driver is removed and the compatible
string is folded into this driver.

Changes from RFC [1]:
 - Removed max-brightness DT property.
 - Added #address-cells and #size-cells properties to the example DT.
 - Refer to these devices as "LED controllers" in Kconfig.
 - Removed redundant last sentence from Kconfig entry
 - Removed unnecessary debug code.
 - Do not set led_classdev.brightness to 0 explicitly, as it is
   already initialized to 0 by devm_kzalloc().
 - Used of_property_read_string() instead of of_get_property().
 - Fail immediately on DT parsing error in a child node, rather than
   continuing on with the non-faulty ones.
 - Added additional comments for some things that might be non-obvious.
 - Added constants for the location of the SSD bit in the SHUTDOWN
   register, and the 3216's CONFIG register.
 - Added special sw_shutdown_func for the 3216 device, as that bit
   is in a different register, at a different position, and has reverse
   polarity compared to all the other devices.
 - Refactored is31fl32xx_init_regs() to separate out some logic into
   is31fl32xx_reset_regs() and is31fl32xx_software_shutdown().
 - Added 4th patch to replace the now-redundant leds-sn3218.
