these are all missing the entry to set them to external boost:
register "boost_type" = "1"

PS32, Line 177: register "boost_peak_milliamp" = "4500"
              : 				register "boost_ind_nanohenry" = "BOOST_IND_1000_NH"
              : 				register "boost_cap_microfarad" = "24"
these aren't required for external boost.

same for below chips.

PS32, Line 182: register "gpio_src_select[0]" = "GPIO_SRC_HIGH_IMPEDANCE"
the driver will override this anyway, so not critical, but gpio_src_select[0] should be GPIO_SRC_GPIO.

same for below chips.
