From: David Rivshin <drivs...@allworx.com> 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.
