Subject: [PATCH 2/3] b43: LCN-PHY: implement disabling radio
Date: Sun, 14 Aug 2011 23:27:29 +0200 [thread overview]

wl reads radio version, then disables it. That's how we found it in MMIO
dump:
radio_read(0x0000) -> 0x0031 <-- RADIO READ WITHOUT 0x200 SET!
radio_read(0x0001) -> 0x0064 <-- RADIO READ WITHOUT 0x200 SET!
radio_read(0x0002) -> 0x0020 <-- RADIO READ WITHOUT 0x200 SET!
read32 0xfaafc120 -> 0x04000400
phy_read(0x044d) -> 0x0000
phy_write(0x044d) <- 0x0000
phy_read(0x044c) -> 0x1fff
phy_write(0x044c) <- 0x1fff
phy_read(0x04b7) -> 0x0000
phy_write(0x04b7) <- 0x0000
phy_read(0x04b1) -> 0x0000
phy_write(0x04b1) <- 0x0000
phy_read(0x04b0) -> 0x7dff
phy_write(0x04b0) <- 0x7dff
phy_read(0x04fa) -> 0x0000
phy_write(0x04fa) <- 0x0000
phy_read(0x04f9) -> 0x007f
phy_write(0x04f9) <- 0x007f

OFC, MMIO hacks were used to find masks & sets.
Sets were taken from:
>>> Switch Radio(OFF) start
phy_read(0x044d) -> 0x0000
phy_write(0x044d) <- 0x0000
phy_read(0x044c) -> 0x0000
phy_write(0x044c) <- 0x1f00
phy_read(0x04b7) -> 0x0000
phy_write(0x04b7) <- 0x0000
phy_read(0x04b1) -> 0x0000
phy_write(0x04b1) <- 0x0000
phy_read(0x04b0) -> 0x0000
phy_write(0x04b0) <- 0x0808
phy_read(0x04fa) -> 0x0000
phy_write(0x04fa) <- 0x0000
phy_read(0x04f9) -> 0x0000
phy_write(0x04f9) <- 0x0008
>>> Switch Radio(OFF) end
Masks were taken from:
phy_read(0x044d) -> 0xffff
phy_write(0x044d) <- 0x83ff
phy_read(0x044c) -> 0xffff
phy_write(0x044c) <- 0xffff
phy_read(0x04b7) -> 0xffff
phy_write(0x04b7) <- 0x80ff
phy_read(0x04b1) -> 0xffff
phy_write(0x04b1) <- 0xdfff
phy_read(0x04b0) -> 0xffff
phy_write(0x04b0) <- 0xffff
phy_read(0x04fa) -> 0xffff
phy_write(0x04fa) <- 0xfff7
phy_read(0x04f9) -> 0xffff
phy_write(0x04f9) <- 0xffff
