The Rockchip pinctrl driver was calling
rockchip_gpio_direction_output() in the pin_config_set() callback.
This was just a shortcut for:
* rockchip_gpio_set()
* pinctrl_gpio_direction_output()
Unfortunately it's not so good to call pinctrl_gpio_direction_output()
from pin_config_set(). Specifically when initting hogs you'll get an
error.
Let's refactor a little so we can call
_rockchip_pmx_gpio_set_direction() directly.

The rockchip pinctrl driver uses irq_gc_set_wake() but doesn't setup
the .wake_enabled member. That means that we can never actually use a
pin for wakeup. When "irq_set_irq_wake()" tries to call through it
will always get a failure from set_irq_wake_real() and will then set
wake_depth to 0. Assuming you can resume you'll later get an error
message about "Unbalanced IRQ x wake disable".

dclk_vop0/1 is the source of HDMI TMDS clock in rk3288, usually we
use 594MHz for clock source of dclk_vop0/1.
HDMI CTS 7-9 require TMDS Clock jitter is lower than 0.25*Tbit:
TMDS clock(MHz) CTS require jitter (ps)
297 84.2
148.5 168
74.25 336
27 1247
PLL BW and VCO frequency effects the jitter of PLL output clock,
clock jitter is better if BW is lower or VCO frequency is higher.
If PLL use default setting of RK3066_PLL_RATE( 594000000, 2, 198, 4),
the TMDS Clock jitter is higher than 250ps, which means we can't
pass the test when TMDS clock is 297MHz or 148.5MHz.
If we use RK3066_PLL_RATE_BWADJ(594000000, 1, 198, 8, 1),
the TMDS Clock jitter is about 60ps and we can pass all test case.
So we need this patch to make hdmi si test pass.

The WARN_ON in inet_evict_bucket can be triggered by a valid case:
inet_frag_kill and inet_evict_bucket can be running in parallel on the
same queue which means that there has been at least one more ref added
by a previous inet_frag_find call, but inet_frag_kill can delete the
timer before inet_evict_bucket which will cause the WARN_ON() there to
trigger since we'll have refcnt!=1. Now, this case is valid because the
queue is being "killed" for some reason (removed from the chain list and
its timer deleted) so it will get destroyed in the end by one of the
inet_frag_put() calls which reaches 0 i.e. refcnt is still valid.

When the evictor is running it adds some chosen frags to a local list to
be evicted once the chain lock has been released but at the same time
the *frag_queue can be running for some of the same queues and it
may call inet_frag_kill which will wait on the chain lock and
will then delete the queue from the wrong list since it was added in the
eviction one. The fix is simple - check if the queue has the evict flag
set under the chain lock before deleting it, this is safe because the
evict flag is set only under that lock and having the flag set also means
that the queue has been detached from the chain list, so no need to delete
it again.
An important note to make is that we're safe w.r.t refcnt because
inet_frag_kill and inet_evict_bucket will sync on the del_timer operation
where only one of the two can succeed (or if the timer is executing -
none of them), the cases are:
1. inet_frag_kill succeeds in del_timer
- then the timer ref is removed, but inet_evict_bucket will not add
this queue to its expire list but will restart eviction in that chain
2. inet_evict_bucket succeeds in del_timer
- then the timer ref is kept until the evictor "expires" the queue, but
inet_frag_kill will remove the initial ref and will set
INET_FRAG_COMPLETE which will make the frag_expire fn just to remove
its ref.
In the end all of the queue users will do an inet_frag_put and the one
that reaches 0 will free it. The refcount balance should be okay.

We're moving omaps to use device tree based booting and already have
omap2, omap4, omap5, am335x and am437x booting in device tree only
mode.
Only omap3 still has legacy booting still around and we really want
to make that device tree only. So let's add a warning about deprecated
legacy booting so we get people to upgrade their boards to use device
tree based booting and find out about any remaining issues.
Note that for most boards we already have the .dts file and those can
be booted with without changing the bootloader using the appended
DTB mode.

Add a sysctl that causes an interface's optimistic addresses
to be considered equivalent to other non-deprecated addresses
for source address selection purposes. Preferred addresses
will still take precedence over optimistic addresses, subject
to other ranking in the source address selection algorithm.
This is useful where different interfaces are connected to
different networks from different ISPs (e.g., a cell network
and a home wifi network).
The current behaviour complies with RFC 3484/6724, and it
makes sense if the host has only one interface, or has
multiple interfaces on the same network (same or cooperating
administrative domain(s), but not in the multiple distinct
networks case.
For example, if a mobile device has an IPv6 address on an LTE
network and then connects to IPv6-enabled wifi, while the wifi
IPv6 address is undergoing DAD, IPv6 connections will try use
the wifi default route with the LTE IPv6 address, and will get
stuck until they time out.
Also, because optimistic nodes can receive frames, issue
an RTM_NEWADDR as soon as DAD starts (with the IFA_F_OPTIMSTIC
flag appropriately set). A second RTM_NEWADDR is sent if DAD
completes (the address flags have changed), otherwise an
RTM_DELADDR is sent.
Also: add an entry in ip-sysctl.txt for optimistic_dad.

into an RB tree), I hit the max reordering level of linux TCP stack.
Reordering level was limited to 127 for no good reason, and some

throughput.
Allow a new max limit of 300, and add a sysctl to allow admins to even
allow bigger (or lower) values if needed.
