Analog is switched on right after reading PHY version:
read16 0xfaafc3e0 -> 0xa801
phy_read(0x043b) -> 0x0000
phy_write(0x043b) <- 0x0000
Switched off after after killing radio:
>>> Switch Radio(OFF) end
phy_read(0x043c) -> 0x0000
phy_write(0x043c) <- 0x0007
phy_read(0x043b) -> 0x0000
phy_write(0x043b) <- 0x0007

Again, MMIO hacks to find masks & sets.
Sets came from:
>>> analog(OFF) start
phy_read(0x043c) -> 0x0000
phy_write(0x043c) <- 0x0007
phy_read(0x043b) -> 0x0000
phy_write(0x043b) <- 0x0007
>>> analog(OFF) end
There is no masking for OFF:
>>> analog(OFF) start
phy_read(0x043c) -> 0xffff
phy_write(0x043c) <- 0xffff
phy_read(0x043b) -> 0xffff
phy_write(0x043b) <- 0xffff
>>> analog(OFF) end
Mask for ON came from
phy_read(0x043b) -> 0xffff
phy_write(0x043b) <- 0xfff8
(there was not masking for ON).
