++PFUZE100 family of regulators
++
++Required properties:
++- compatible: "fsl,pfuze100"
++- reg: I2C slave address
++- regulators: This is the list of child nodes that specify the regulator
++ initialization data for defined regulators. Please refer to below doc
++ Documentation/devicetree/bindings/regulator/regulator.txt.
++
++ The valid names for regulators are:
++ sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
++
++Each regulator is defined using the standard binding for regulators.
++

+Subject: [PATCH] regulator: pfuze100: Fix n_voltages setting for SW2~SW4 with
+ high bit set
+
+Current code adjust min_uV and uV_step but missed adjusting the n_voltages
+setting.
+
+When BIT6 is clear:
+ n_voltages = (1975000 - 400000) / 25000 + 1 = 64
+When BIT6 is set:
+ n_voltages = (3300000 - 800000) / 50000 + 1 = 51
+
+The n_voltages needs update because when BIT6 is set 0x73 ~ 0x7f are reserved.
+When using regulator_list_voltage_linear, the n_voltages does matter here
+because wrong n_voltages setting make the equation return wrong result.
+e.g. if selector is 63, regulator_list_voltage_linear returns
+ 800000 + (50000 * 63) = 4000000
+ It should return -EINVAL if the selector is in the range of 51 ~ 63.

+
+Simplify the equation to calculate ramp_delay.
+Below equations are equivalent:
+ ramp_delay = 25000 / (2 * ramp_delay);
+ ramp_delay = 50000 / (4 * ramp_delay);
+ ramp_delay = 25000 / (2 * ramp_delay);
+ ramp_delay = 12500 / ramp_delay;
+So we don't need to read BIT6 of rdev->desc->vsel_reg for applying different
+equations.
+
+Also use rdev->desc->vsel_reg instead of run-time calculate register address.
