41 * BBP and RF register require indirect register access,
42 * and use the CSR registers PHY_CSR3 and PHY_CSR4 to achieve this.
43 * These indirect registers work with busy bits,
44 * and we will try maximal REGISTER_BUSY_COUNT times to access
45 * the register while taking a REGISTER_BUSY_DELAY us delay
46 * between each attampt. When the busy bit is still set at that time,
47 * the access attempt is considered to have failed,
48 * and we will print an error.
