There are new (not anymore?) Broadcom 802.11ac wireless cards based on chipsets like BCM4352 and BCM4360. They use a new PHY type (called simply AC) that will require new specific code. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2015-01-29b43: Fix locking FIXME in beacon update top halfMichael Büsch
b43 has a FIXME about locking in the mac80211 set-beacon-int callback for a long time. As it turns out there actually is a tiny race window that could result in a use-after-free bug of the 'current_beacon' memory. Nobody ever reported this, so it probably never happened. Fix this by adding a spin lock that protects the current_beacon access. We must not be in atomic context while accessing hardware (due to SDIO), so the beacon update bottom half has to clone the skb and release the lock before writing it to hardware. Let's all hope that this stops the troll who is trying to submit incorrect fixes for this issue repeatedly. And let's hope that I'm not a troll, too, who just hides even more evil code in an even more complex attempt to fix the issue.

2014-11-10b43: fix NULL pointer dereference in b43_phy_copy()Hauke Mehrtens
phy_read and phy_write are not set for every phy any more sine this: commit d342b95dd735014a590f9051b1ba227eb54ca8f6 Author: Rafał Miłecki <zajec5@gmail.com> Date: Thu Jul 31 21:59:43 2014 +0200 b43: don't duplicate common PHY read/write ops b43_phy_copy() accesses phy_read and phy_write directly and will fail with some phys. This patch fixes the regression by using the b43_phy_read() and b43_phy_write() functions which should be used for read and write access.

2014-08-25b43: implement PPR (Power Per Rate) management/APIRafał Miłecki
Broadcom hardware supports auto-adjustment of TX power depending on the currently used rate. So far all calculations were handled without any helpers (API) using big arrays and magic offsets. It seems Broadcom recently decided to clean this up by developing PPR. Their wlc_ppr.h can be found in open parts of the SDK. As we plan to implement support for rate-based TX power it makes sense to also implement our version of PPR as well. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W.

2014-08-25b43: flush some writes on Broadcom MIPS SoCsRafał Miłecki
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>
2014-08-25b43: don't duplicate common PHY read/write opsRafał Miłecki
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>
2014-08-25b43: update flushing many writes performed in a rowRafał Miłecki

2014-07-31b43: N-PHY: fix "Data bus error" while working in 5 GHzRafał Miłecki
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).

It contains radio 0x2057 rev 14 just like a BCM43217, so it doesn't require any magic. The main difference is that BCM4313 is 1x1:1. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
