62f7f3eca4 tps6105x: add optional devicetree support 
This driver currently requires platform data to specify the
operational mode and regulator init data (in case of regulator
mode).

Optionally specify the operational mode by looking at the name
of the devicetree child node.

Example: put chip in regulator mode:

i2c0 {
	tps61052@33 {
		compatible = "ti,tps61052";
		reg = <0x33>;

		regulator {
                            regulator-min-microvolt = <5000000>;
                            regulator-max-microvolt = <5000000>;
                            regulator-always-on;
		};
	};
};

458ea3ad03 regulator: ab8500: Remove SYSCLKREQ from enum ab8505_regulator_id 
Those regulators are not actually supported by the AB8500 regulator
driver. There is no ab8500_regulator_info for them and no entry in
ab8505_regulator_match.

As such, they cannot be registered successfully, and looking them
up in ab8505_regulator_match causes an out-of-bounds array read.

99c4f70df3 regulator: ab8500: Remove AB8505 USB regulator 
The USB regulator was removed for AB8500 in
commit 41a06aa738 ("regulator: ab8500: Remove USB regulator").
It was then added for AB8505 in
commit 547f384f33 ("regulator: ab8500: add support for ab8505").

However, there was never an entry added for it in
ab8505_regulator_match. This causes all regulators after it
to be initialized with the wrong device tree data, eventually
leading to an out-of-bounds array read.

Given that it is not used anywhere in the kernel, it seems
likely that similar arguments against supporting it exist for
AB8505 (it is controlled by hardware).

Therefore, simply remove it like for AB8500 instead of adding
an entry in ab8505_regulator_match.

f7907e57ae regulator: fixed: add off-on-delay 
Depends on board design, the gpio controlling regulator may
connects with a big capacitance. When need off, it takes some time
to let the regulator to be truly off. If not add enough delay, the
regulator might have always been on, so introduce off-on-delay to
handle such case.

87fd0db6d7 regulator: Document "regulator-boot-on" binding more thoroughly 
The description of "regulator-boot-on" was a little unclear, at least
to me.  Did this property mean that we should turn the regulator on at
boot?  Or perhaps it was intended only to be used for regulators where
we couldn't read the state at bootup to indicate what state we should
assume?  The answer, it turns out, is both [1].

Let's document this.

1252b28314 regulator: pfuze100-regulator: Variable "val" in pfuze100_regulator_probe() could be uninitialized 
In function pfuze100_regulator_probe(), variable "val" could be
initialized if regmap_read() fails. However, "val" is used to
decide the control flow later in the if statement, which is
potentially unsafe.

This Power IC is used in combination with various PMIC combos,
generally found on boards with MSM8992, MSM8994, MSM8996,
MSM8956, MSM8976 and others, usually at address 0x5 on the SPMI
bus, and its usual usage is to provide power to the GPU and/or
to the CPU clusters (APC0/APC1).
