b43: AC-PHY: prepare place for developing new PHY support

2015-01-29T08:54:43+00:00

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.

b43: fix NULL pointer dereference in b43_phy_copy()

2014-11-10T18:10:24+00:00

phy_read and phy_write are not set for every phy any more sine this:

    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.

This should fix this bug report:

b43: flush some writes on Broadcom MIPS SoCs

2014-08-25T20:00:42+00:00

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).

b43: don't duplicate common PHY read/write ops

2014-08-25T20:00:42+00:00

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.

b43: update flushing many writes performed in a row

2014-08-25T20:00:42+00:00

Flush radio writes as well and add some tiny optimizations (e.g.
masksetting PHY reg involves reading it, so reset the counter).

b43: add config for (en|dis)abling G-PHY support

2014-06-20T18:13:46+00:00

This allows new devices users to save some space.

b43: remove leftover code from old devices support

2014-06-20T18:13:45+00:00

Old devices (A-PHY or B-PHY) are supposed to be supported by b43legacy.
We keep phy_a.c as it's needed for G-PHY which shares some design.
