2015-11-18b43: move under broadcom vendor directoryKalle Valo1-6726/+0
Part of reorganising wireless drivers directory and Kconfig. Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2014-09-15b43: Implement PHY PLL resetRafał Miłecki1-1/+1
We should reset PLL after changing MAC frequency. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-08-25b43: N-PHY: add RF power tables for radio 0x2057 revs 9 & 14Rafał Miłecki1-3/+18
Don't write them as we don't have gains configured correctly yet. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-08-25b43: flush some writes on Broadcom MIPS SoCsRafał Miłecki1-3/+3
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 Miłecki1-16/+0
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 Miłecki1-0/+1
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>
2014-07-31b43: N-PHY: fix "Data bus error" while working in 5 GHzRafał Miłecki1-0/+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).

2014-07-29b43: add support for BCM43131 chipset with N-PHY rev 17Rafał Miłecki1-1/+2
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>
2014-07-23b43: N-PHY: don't calculate values for TSSI if we can't transmitRafał Miłecki1-1/+2
This process requires sending some sample tone, so make sure we're allowed to transmit first. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-07-22b43: N-PHY: allow applying separated workarounds per coreRafał Miłecki1-54/+71
Newer devices need different workarounds for cores 0 and 1. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-07-22b43: N-PHY: update generic rev7+ workaroundsRafał Miłecki1-41/+79
Add some missing ops and prepare for new devices support. This patch is a great stability improvement for BCM43217. Earlier Tenda W322E used to disconnect every 2 minutes (16 times over 30 minutes). With this fix I got it running for 4 hours (with iperf) without any disconnection. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-07-01b43: N-PHY: complete generic support for 0x2057 radioRafał Miłecki1-8/+124
It doesn't include any device (radio revision) specific code yet, so it isn't really usable. As the commit says, it's just some generic code. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
