* b43: flush some writes on Broadcom MIPS SoCsRafał Miłecki2014-08-2511-29/+49
| | | | | | | | | | Access to PHY and radio registers is indirect on Broadcom hardware and it seems that addressing on some MIPS SoCs may require flushing. So far this problem was noticed on 0x4716 SoC only (marketing names: BCM4717, BCM4718). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: don't duplicate common PHY read/write opsRafał Miłecki2014-08-255-60/+12
| | | | | | | | | Most of the PHYs use the same way of accessing registers, so move that code to the shared place. An exception is G-PHY which sometimes access A-PHY regs and requires special handling. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: update flushing many writes performed in a rowRafał Miłecki2014-08-253-3/+25
| | | | | | | | Flush radio writes as well and add some tiny optimizations (e.g. masksetting PHY reg involves reading it, so reset the counter). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: N-PHY: fix "Data bus error" while working in 5 GHzRafał Miłecki2014-07-311-0/+3
| | | | | | | | | | | | When switching from one 5 GHz channel to another 5 GHz channel we need to make sure BPHY is still in a reset. However to access BPHY register we have to switch to 2 GHz mode for a moment. Otherwise this may result in "Data bus error" (noticed by Hauke with BCM43224 connected to the SoC).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for firmware rev 508+ was added years ago, but we never noticed it reports channel in a different way for G-PHY devices. Instead of offset from 2400 MHz it simply passes channel id (AKA hw_value). So far it was (most probably) affecting monitor mode users only, but the following recent commit made it noticeable for quite everybody: commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7 Author: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Date: Tue Mar 4 16:50:13 2014 +0200 cfg80211/mac80211: ignore signal if the frame was heard on wrong channel Reported-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Cc: stable@vger.kernel.org Tested-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: John W.
