Detailed Description

DOC: RF Buffer registers

There are some special registers on the RF chip that control various operation settings related mostly to the analog parts (channel, gain adjustment etc).

We don't write on those registers directly but we send a data packet on the chip, using a special register, that holds all the settings we need. After we've sent the data packet, we write on another special register to notify hw to apply the settings. This is done so that control registers can be dynamically programmed during operation and the settings are applied faster on the hw.

We call each data packet an "RF Bank" and all the data we write (all RF Banks) "RF Buffer". This file holds initial RF Buffer data for the different RF chips, and various info to match RF Buffer offsets with specific RF registers so that we can access them. We tweak these settings on rfregs_init function.
