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. arch/arm/mach-msm/board-halibut.c | 8 ++++- arch/arm/mach-msm/board-qsd8x50.c | 8 ++++- arch/arm/mach-pxa/idp.c | 5 +++ arch/arm/mach-pxa/lpd270.c | 8 ++++- arch/arm/mach-realview/core.c | 7 ++++ arch/arm/mach-realview/realview_eb.c | 2 +- arch/arm/mach-sa1100/neponset.c | 6 ++++ arch/arm/mach-sa1100/pleb.c | 7 ++++ drivers/net/ethernet/smsc/smc91x.c | 9 +++-- drivers/net/ethernet/smsc/smc91x.h | 114 ++---------------------------------------------------------- 10 files changed, 57 insertions(+), 117 deletions(-) Tested-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: David S.
