- change this for overclocking
- 540672: 528 MHz (stock speed for Rhodium)
- 716800: 700 MHz
- 786432: 768 MHz
- board-htcraphael-navi.wake
- Controls which buttons wake the device from sleep. (board-htcraphael-navi.c)
- 0: ?

- Advanced Host Bus (AHB) divider. (clock-7x00.c)
- clock-7x00.mddi
- Mobile Display Digital Interface (MDDI) clock address/offset/? (e.g. 0xa51 or 0xe2c) (clock-7x00.c)
- external.rhod_speaker
- 1: enable external speaker
- gsensor_axis
- Maps the hardware accelerometer axes to software.
