22 * DOC: RF Buffer registers
23 *
22 * There are some special registers on the RF chip
23 * that control various operation settings related mostly to
24 * the analog parts (channel, gain adjustment etc).
25 *
26 * We don't write on those registers directly but
27 * we send a data packet on the chip, using a special register,
28 * that holds all the settings we need. After we've sent the
29 * data packet, we write on another special register to notify hw

--- 9 unchanged lines hidden (view full) ---

39 *
40 * Also check out reg.h and U.S. Patent 6677779 B1 (about buffer
41 * registers and control registers):
