According to the TPS65219 datasheet, selectors 0x38 through 0x3f
saturate at 3.4 V for LDO1 and LDO2.
For LDO3 and LDO4, selectors 0x00 through 0x0c saturate at
1.2 V, while selectors 0x36 through 0x3f saturate at 3.3 V.
The driver currently uses 0x56, 0x12, and 0x54 as selector boundary
values. These values do not match the selector boundaries defined by
the datasheet.
Use the correct selector boundary values of 0x38, 0x0c, and 0x36
for interpolation.
