192The regulator node houses sub-nodes for each regulator within the device. Each
193sub-node is identified using the node's name, with valid values listed for each
194of the PMICs below.

222The content of each sub-node is defined by the standard binding for regulators -
223see regulator.txt - with additional custom properties described below:
224
225- regulator-initial-mode:
226	Usage: optional
227	Value type: <u32>
228	Description: 2 = Set initial mode to auto mode (automatically select
229		    between HPM and LPM); not available on boost type
230		    regulators.
231
232		    1 = Set initial mode to high power mode (HPM), also referred
233		    to as NPM. HPM consumes more ground current than LPM, but
234		    it can source significantly higher load current. HPM is not
235		    available on boost type regulators. For voltage switch type
236		    regulators, HPM implies that over current protection and
237		    soft start are active all the time.
238
239		    0 = Set initial mode to low power mode (LPM).
240
241- qcom,ocp-max-retries:
242	Usage: optional
243	Value type: <u32>
244	Description: Maximum number of times to try toggling a voltage switch
245		     off and back on as a result of consecutive over current
246		     events.
247
248- qcom,ocp-retry-delay:
249	Usage: optional
250	Value type: <u32>
251	Description: Time to delay in milliseconds between each voltage switch
252		     toggle after an over current event takes place.
253
254- qcom,pin-ctrl-enable:
255	Usage: optional
256	Value type: <u32>
257	Description: Bit mask specifying which hardware pins should be used to
258		     enable the regulator, if any; supported bits are:
259			0 = ignore all hardware enable signals
260			BIT(0) = follow HW0_EN signal
261			BIT(1) = follow HW1_EN signal
262			BIT(2) = follow HW2_EN signal
263			BIT(3) = follow HW3_EN signal
264
265- qcom,pin-ctrl-hpm:
266	Usage: optional
267	Value type: <u32>
268	Description: Bit mask specifying which hardware pins should be used to
269		     force the regulator into high power mode, if any;
270		     supported bits are:
271			0 = ignore all hardware enable signals
272			BIT(0) = follow HW0_EN signal
273			BIT(1) = follow HW1_EN signal
274			BIT(2) = follow HW2_EN signal
275			BIT(3) = follow HW3_EN signal
276			BIT(4) = follow PMIC awake state
277
278- qcom,vs-soft-start-strength:
279	Usage: optional
280	Value type: <u32>
281	Description: This property sets the soft start strength for voltage
282		     switch type regulators; supported values are:
283			0 = 0.05 uA
284			1 = 0.25 uA
285			2 = 0.55 uA
286			3 = 0.75 uA
287
288- qcom,saw-slave:
289	Usage: optional
290	Value type: <boo>
291	Description: SAW controlled gang slave. Will not be configured.
292
293- qcom,saw-leader:
294	Usage: optional
295	Value type: <boo>
296	Description: SAW controlled gang leader. Will be configured as
297		     SAW regulator.
