b43: HT-PHY: init radio when enabling it
Masks and sets were found in MMIO dumps by using MMIO hacks. Shortly: radio_write(0x0c51) <- 0x0070 radio_write(0x0c5a) <- 0x0003 radio_write(0x0146) <- 0x0003 radio_write(0x0546) <- 0x0003 radio_write(0x0946) <- 0x0003 radio_write(0x002e) <- 0x0078 radio_write(0x00c0) <- 0x0080 radio_write(0x002e) <- 0xff87 radio_write(0x00c0) <- 0xff7f radio_write(0x0011) <- 0xfff7 Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W.
