Signed-off-by: Rafa? Mi?ecki <zajec5@gmail.com> --- As always, I've hacked MMIO ops to return 0xFFFF for 0x908 PHY reg. This allowed finding masks used by closed source driver. At the beginning 0x908 PHY reg ops are following: phy_read(0x0908) -> 0xffff phy_write(0x0908) <- 0x0002 (...) phy_read(0x0908) -> 0xffff phy_write(0x0908) <- 0x0020 (...) phy_read(0x0908) -> 0xffff phy_write(0x0908) <- 0x0200 Later this is always like this: phy_read(0x0908) -> 0xffff phy_write(0x0908) <- 0x0000 We do not know the proper condition yet, let's use FIXME for it. --- drivers/net/wireless/b43/phy_ht.c | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-)
