net: smc91x: use run-time configuration on all ARM machines
The smc91x driver traditionally gets configured at compile-time
for whichever hardware it runs on. This no longer works on
ARM as we continue to move to building all-in-one kernels.
Most ARM configurations with this driver already use run-time
configuration through DT or through platform_data, but a
few have not been converted yet.
I've checked all ARM boards that use this driver in their
legacy board files, and converted the ones that were using
compile-time configuration in smc91x.h to behave like the
other ones and provide the interrupt polarity along with
the MMIO configuration (width, stride) at platform device
creation time.
In particular, these combinations were previously selectable
in Kconfig but in fact broken:
- sa1100 assabet plus pleb
- msm combined with any other armv6/v7 platform
- pxa-idp combined with any non-DMA pxa variant
- LogicPD PXA270 combined with any other pxa
- nomadik combined with any other armv4/v5 platform,
e.g. versatile.
None of these seem critical enough to warrant a backport
to stable, but it would be nice to clean this up for good.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
----
I would like the patch to get merged through netdev, after
Robert and/or Linus have verified it on at least some hardware.
There are a few other non-ARM platforms using this driver,
I could do the same patch for those if we want to take
it further.

net: smc91x: fix SMC accesses
Commit b70661c70830 ("net: smc91x: use run-time configuration on all ARM
machines") broke some ARM platforms through several mistakes. Firstly,
the access size must correspond to the following rule:
(a) at least one of 16-bit or 8-bit access size must be supported
(b) 32-bit accesses are optional, and may be enabled in addition to
the above.
Secondly, it provides no emulation of 16-bit accesses, instead blindly
making 16-bit accesses even when the platform specifies that only 8-bit
is supported.
Reorganise smc91x.h so we can make use of the existing 16-bit access
emulation already provided - if 16-bit accesses are supported, use
16-bit accesses directly, otherwise if 8-bit accesses are supported,
use the provided 16-bit access emulation. If neither, BUG(). This
exactly reflects the driver behaviour prior to the commit being fixed.
Since the conversion incorrectly cut down the available access sizes on
several platforms, we also need to go through every platform and fix up
the overly-restrictive access size: Arnd assumed that if a platform can
perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access
size needed to be specified - not so, all available access sizes must
be specified.
This likely fixes some performance regressions in doing this: if a
platform does not support 8-bit accesses, 8-bit accesses have been
emulated by performing a 16-bit read-modify-write access.
Tested on the Intel Assabet/Neponset platform, which supports only 8-bit
accesses, which was broken by the original commit.
