2015-01-29b43: AC-PHY: prepare place for developing new PHY supportRafał Miłecki1-0/+10
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: support bcma core reset on AC-PHY hardwareRafał Miłecki1-0/+17

2015-01-29b43: Fix locking FIXME in beacon update top halfMichael Büsch1-11/+32
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.

2014-08-25b43: flush some writes on Broadcom MIPS SoCsRafał Miłecki1-9/+8
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>

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>

2014-07-22b43: extract one more radio parameter: versionRafał Miłecki1-21/+25
Some radios may share the same ID and revision but differ by a version. E.g. radio in BCM5357B0 is version 1 and requires specific handling. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-07-15b43: don't warn about no 5 GHz support on 2.4 GHz devicesRafał Miłecki1-8/+10

2014-07-15b43: always print info about radio (manuf, id, revision)Rafał Miłecki1-4/+4
Type of radio has a major meaning for the driver. There is quite some code that does initialization/calibration depending on the radio rev.

This fixes regression introduced by adding some G-PHY devices to the list of dual band devices. There is simply no support for 5 GHz on G-PHY devices in b43.

2014-05-29b43: PHY: allow init optimizations by tracking PHY stateRafał Miłecki1-0/+3
PHY has to be often re-initialized (e.g. during band switching after PHY reset), however some operations have to be performed only once (only power reset affects them). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-05-22b43: fix list of 5 GHz channels for 802.11n cardsRafał Miłecki1-12/+22
Broadcom hardware uses a bit tricky hw_value-s for 5 GHz channels, values 184-228 are used for 4920-5140 MHz center frequencies. Normally you expect channels 7-16 (e.g. 5060 MHz is channel 12, not 212). We never meant to register hw_value 228 with freq 6140 MHz (5000 + 228 * 5).

2014-05-19b43: split upload of init values into 2 functionsRafał Miłecki1-15/+22
There are two groups of init values. The first one has to be uploaded once per wireless core reset but the second one on every band switch.
