Subject: [PATCH] mfd: ab8500: Rewrite bindings in YAML
This rewrites the former text based AB8500 bindings in YAML.
When the AB8500 bindings were first written (in 2012) we
were not strict on some things and node names were definitely
not standardized.
This patch uses standard node names to most of the subnodes
on the AB8500 and is accompanied by another patch fixing
all the DTS files to conform to this.
The bindings are not as perfect as newly written bindings
would be, it is a best effort to deal with the legacy.

+
+description:
+ the AB8500 "Analog Baseband" is the mixed-signals integrated circuit
+ handling power management (regulators), analog-to-digital conversion
+ (ADC), battery charging, fuel gauging of the battery, battery-backed
+ RTC, PWM, USB PHY and some GPIO lines in the ST-Ericsson U8500 platforms
+ in connection with the DB8500 digital baseband. The DB8500 PRCMU
+ communicates directly and autonomously with the AB8500 and thus it
+ appears as a subnode of the DB8500 PRCMU. An altered version called
+ AB8505 also exist, the difference in AB8505 is that some of the USB and
+ USB charging handling has changed, and it has an embedded USB-to-serial
+ converter. Most subblocks takes their interrupts directly from the
+ AB8500 embedded interrupt controller.
