This patch moves the following select's:
- RFKILL : IWLWIFI_RFKILL -> IWLCORE
- RFKILL_INPUT : IWLWIFI_RFKILL -> IWLCORE
- MAC80211_LEDS : IWL4965_LEDS -> IWLCORE
- LEDS_CLASS : IWL4965_LEDS -> IWLCORE
- MAC80211_LEDS : IWL3945_LEDS -> IWL3945
- LEDS_CLASS : IWL3945_LEDS -> IWL3945
The effects are:
- with IWLCORE=m and/or IWL3945=m RFKILL/RFKILL_INPUT/MAC80211_LEDS/LEDS_CLASS
are no longer wrongly forced to y
- fixes a build error with IWLCORE=y, IWL4965=m
might be a bug in kconfig causing it, but doing this change that is
anyway the right thing fixes it

TBIPA needs to be set to a value (on connected MDIO buses) that
doesn't conflict with PHYs on the bus. By hardcoding it to 0x1f,
we were preventing boards with PHYs at 0x1f from working properly.
Instead, scan the bus when it comes up, and find an address that
doesn't have a PHY on it. The TBI PHY configuration code then
trusts that the value in TBIPA is either safe, or doesn't matter
(ie - it's not an active bus with other PHYs).

packet if it failed.

Since 43cc71eed1, the platform modalias is
prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable network
platform drivers, to re-enable auto loading.
NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support.
That looks problematic in the first place (it even uses the ancient "struct
device_driver" binding scheme for platform_bus!) and I suspect it will vanish
soonish when arch/powerpc rules the world. Also, drivers/net/ne.c would have
needed more thought to sort out.

While trying to fix http://bugzilla.kernel.org/show_bug.cgi?id=8952
I looked at a few other drivers to figure out what drivers _should_
be doing for suspend/resume. I noticed typhoon driver is likely doing
more than it needs to. Patch below is untested since I don't have the HW.
Suspend/resume code across NIC drivers is fairly inconsistent.
And I couldn't find any documentation on what the canonical sequence
NICs need to do for suspend or resume. Is there any?
Barring contrary advice, I'm going model the tulip suspend/resume
fixes after tg3.c since a number of "modern" (< 5 years old) laptops
have that and I'm silly enough to assume it works.

This patch adds ibm_newemac PHY clock workaround for 440EP/440GR EMAC
attached to a PHY which doesn't generate RX clock if there is no link.
The code is based on the previous ibm_emac driver stuff. The 440EP/440GR
allows controlling each EMAC clock separately as opposed to global clock
selection for 440GX.
BenH: Made that #ifdef CONFIG_PPC_DCR_NATIVE for now as dcri_* stuff doesn't
exist for MMIO type DCRs like Cell. Some future rework & improvements of the
DCR infrastructure will make that cleaner but for now, this makes it work.

The PowerPC 440GX Taishan board fails to reset EMAC3 (reset timeout
error) if there's no link. Because of that it fails to find PHY
chip. The older ibm_emac driver had a workaround for that: the
EMAC_CLK_INTERNAL/EMAC_CLK_EXTERNAL macros, which toggle the Ethernet
Clock Select bit in the SDR0_MFR register. This patch does the same for
"ibm,emac-440gx" compatible chips. The workaround forces clock on -all-
EMACs, so we select clock under global emac_phy_map_lock.
