Subject: b43: HT-PHY: init radio when enabling it
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3e644ab47e0cbedc7dd694d3af9996dc514ebf4a;p=openwrt%2Fstaging%2Fblogic.git

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
