1 Adaptive Body Bias(ABB) SoC internal LDO regulator for Texas Instruments SoCs
5   - "ti,abb-v1" for older SoCs like OMAP3
6   - "ti,abb-v2" for newer SoCs like OMAP4, OMAP5
7   - "ti,abb-v3" for a generic definition where setup and control registers are
12   - "base-address"	- contains base address of ABB module (ti,abb-v1,ti,abb-v2)
13   - "control-address"	- contains control register address of ABB module (ti,abb-v3)
14   - "setup-address"	- contains setup register address of ABB module (ti,abb-v3)
15   - "int-address"	- contains address of interrupt register for ABB module
19 - clocks: should point to the clock node used by ABB module
20 - ti,settling-time: Settling time in uSecs from SoC documentation for ABB module
23 	computing settling time from SoC Documentation for ABB module(clock
27 - ti,abb_info: An array of 6-tuples u32 items providing information about ABB
30 	volt: voltage in uV - Only used to index ABB information.
31 	ABB mode: one of the following:
42 	      the regulator. Further, ABB LDOs are considered always-on by
47   - "efuse-address"	- Contains efuse base address used to pick up ABB info.
48   - "ldo-address"	- Contains address of ABB LDO override register.
56 	       from efuse-address to pick up ABB characteristics. Set to 0 if
59 		'ABB mode' is force set to RBB mode if value at "efuse-address"
62 		'ABB mode' is force set to FBB mode if value at "efuse-address"
68 Example #1: Simplest configuration (no efuse data, hard coded ABB table):
69 abb_x: regulator-abb-x {
70 	compatible = "ti,abb-v1";
81 	/* uV		ABB	efuse	rbb_m	fbb_m	vset_m */
88 Example #2: Efuse bits contain ABB mode setting (no LDO override capability)
89 abb_y: regulator-abb-y {
90 	compatible = "ti,abb-v2";
101 	/* uV		ABB	efuse	rbb_m	fbb_m	vset_m */
109 Example #3: Efuse bits contain ABB mode setting and LDO override capability
110 abb_z: regulator-abb-z {
111 	compatible = "ti,abb-v2";
128 	/* uV	ABB	efuse	rbb_m	fbb_m	vset_m */
