commit d342b95dd7
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.
This should fix this bug report:

Some constants were missing and are added now.
The rate mode was renamed, at least the ucode in brcsmac uses 2 for HT
rates (iee80211n) and the more recent ucodes are using 3 for VHT
(ieee80211ac).

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.

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).

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.

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).
