eff3549c58 generic: drop support for get_port_stats() on ar8xxx
The implementation is not efficient on ar8xxx switches. It triggers high
CPU load and degrades device performance.

The high CPU load has been traced down to the ar8xxx_reg_wait() call in
ar8xxx_mib_op(), which has to usleep_range() till the MIB busy flag set
by the request to update the MIB counter is cleared.

This commit removes the get_port_stats() code introduced in 4d8a66d and
leaves a note for future hacker's beware.

Fixes: FS#1004

096dff8fcd kernel: rtl8306: fix port link status
In case the link changes from down to up, the register is only updated
on read. If the link failed/was down, this bit will be 0 until after
reading this bit again.

Fixes a reported link down by swconfig alebit the link is up (query for
the link again will show the correct link status)

c30a70fc9f generic: make switch_port_stats tx/rx_bytes long long
This generic structure defines tx_bytes and rx_bytes as unsigned long (u32),
while several devices would typically report unsigned long long (u64).

The code can work as is, but there's a chance that with a sufficiently fast
interface the overflow might happen too fast to be correctly noticed by the
consumers of this data.

This patch makes both field unsigned long long and updates the only known
consumer of this data: swconfig_leds.c

1dace8cbe0 brcm47xx: resolve GPIO conflict for WRT54GSv1
On the Linksys WRT54GSv1, the adm6996 switch driver and the
gpio_button_hotplug module both claim GPIO 6, which is connected to the
Reset button.  When the switch driver's request wins, the Reset button
cannot work. This makes it impossible to enter failsafe mode without a
serial console.

Stop requesting the "adm_rc" GPIO in the switch driver, since it is not
used anywhere.

4052443a23 kernel: don't switch allocate_partition to use mtd_roundup_to_eb
This mtd_roundup_to_eb helper was introduced years ago in the commit
daec7ad768 ("kernel/3.10: add separate rootfs partition parser") and
it was probably supposed to simplify code a bit.

With the recent upstream commit 1eeef2d7483a7 ("mtd: handle partitioning
on devices with 0 erasesize") the logic in allocate_partition got
slightly more complex and we can't use this simple helper anymore as it
doesn't support MTD_NO_ERASE properly.

There also isn't any real gain from this helper, so it's probably easier
to just don't use it *or* work on upstreaming it to avoid maintenance
cost.

913b2290ca mvswitch: fix autonegotiation issue
The Marvel 88E6060 switch has an MDIO interface, but does not emulate
regular PHY behavior for the host. The network core can not detect using
the generic code, whether the connection via the attached PHY can be
used or not. The PHY's state machine is stuck in a state of
auto-negotiation and does not go any further so the Ethernet interface
of the router stay forever in the not-runing state.

Fix this issue by implementing the aneg_done callback to be able to
inform the network core that the Ethernet interface link to which the
switch is connected can be marked as RUNNING.

088e28772c kernel: update kernel 4.4 to version 4.4.69
Refresh patches. A number of patches have landed upstream & hence are no
longer required locally:

062-[1-6]-MIPS-* series
042-0004-mtd-bcm47xxpart-fix-parsing-first-block

Reintroduced lantiq/patches-4.4/0050-MIPS-Lantiq-Fix-cascaded-IRQ-setup
as it was incorrectly included upstream thus dropped from LEDE.
As it has now been reverted upstream it needs to be included again for
LEDE.

Run tested ar71xx Archer C7 v2 and lantiq.

2b27e62e74 linux-4.9: Fix building of DWC3 module
DWC3 driver uses of_usb_get_phy_mode() which is
implemented in drivers/usb/phy/of.c and in bare minimal
configuration it might not be pulled in kernel binary.

In case of ARC or ARM this could be easily reproduced with
"allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m.

On building all ends-up with:
---------------------->8------------------
  Kernel: arch/arm/boot/Image is ready
  Kernel: arch/arm/boot/zImage is ready
  Building modules, stage 2.
  MODPOST 5 modules
ERROR: "of_usb_get_phy_mode" [drivers/usb/dwc3/dwc3.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
---------------------->8------------------

This was affecting Lede in case of CONFIG_ALL_KMODS=y.

The patch is already scheduled for v4.12 and once it is backported to
4.9.y it must be removed from here.

Note this patch makes sense not only for ARC instead it fixes
a generic issue which may affect more arches and platforms thus
putting it in "generic/" folder.
