This key can be used to store a USB string descriptor. The mapping of string descriptor number to the
string stored in this key is controlled by PSKEY_USB_STRING_DESCRIPTORS_MAP.

Type Default Setting
PSKEY_RADIOTEST_FIRST_TRIM_TIME 0x0326 TIME 5 * SECOND
The time from the start of a test till the first IQ trim auto-calibration is done. A value of 0 disables the
automatic calibration completely during the test. A calibration is still done before the test starts.

PSKEY_RADIOTEST_SUBSEQUENT_TRIM_TIME 0x0327 TIME 0
In normal operation, the chip schedules regular trims of the IQ block to prevent degradation of the radio
performance. These are placed so as to avoid interfering with normal radio traffic. This is not possible in
radiotest mode when the transmissions are back to back, hence this key exists to choose the most suitable
behaviour.
Once the first IQ trim auto calibration is done in test mode, then subsequent trims are done at regular
intervals with the period being given by this key, which is a time in microseconds. If the value is 0 then no
