commit 059500940def (ACPI/video: export acpi_video_get_levels)
mistakenly dropped the correct value of max_level and that caused the
set_level function following failed and the acpi_video backlight interface
didn't get created. Fix this by passing back the correct max_level value.
While at it, also fix the param used in acpi_video_device_lcd_query_levels
where acpi_handle is expected but acpi_video_device is passed.

As irqchip and gpiochip functions are orthogonal, the IRQ

get into gpiochip_lock_as_irq(). Make sure to re-read the

enabled for the chip.

The "to_irq" functionality is broken inside this driver since commit
76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler").
The addition of the new lpc32xx irqchip driver in 4.7, fixed the
lpc32xx platform interrupt issue.
When switching to the new lpc32xx irqchip driver, a warning appear
in the lpc32xx gpio driver: warning: "NR_IRQS" redefined.
To remove this warning (temporary solution), this patch
disables the broken "to_irq" mapping functionality support.

initialization"
This reverts commit 7a03fe6f48f3 ("clk: rockchip: reset init state
before mmc card initialization").
Though not totally obvious from the commit message nor from the source
code, that commit appears to be trying to reset the "_drv" MMC clocks to
90 degrees (note that the "_sample" MMC clocks have a shift of 0 so are
not touched).
The major problem here is that it doesn't properly reset things. The
phase is a two bit field and the commit only touches one of the two
bits. Thus the commit had the following affect:
- phase 0 => phase 90
- phase 90 => phase 90
- phase 180 => phase 270
- phase 270 => phase 270
Things get even weirder if you happen to have a bootloader that was
actually using delay elements (should be no reason to, but you never
know), since those are additional bits that weren't touched by the
original patch.
This is unlikely to be what we actually want. Checking on rk3288-veyron
devices, I can see that the bootloader leaves these clocks as:
- emmc: phase 180
- sdmmc: phase 90
- sdio0: phase 90
Thus on rk3288-veyron devices the commit we're reverting had the effect
of changing the eMMC clock to phase 270. This probably explains the
scattered reports I've heard of eMMC devices not working on some veyron
devices when using the upstream kernel.
The original commit was presumably made because previously the kernel
didn't touch the "_drv" phase at all and relied on whatever value was
there when the kernel started. If someone was using a bootloader that
touched the "_drv" phase then, indeed, we should have code in the kernel
to fix that. ...and also, to get ideal timings, we should also have the
kernel change the phase depending on the speed mode. In fact, that's
the subject of a recent patch I posted at
<https://patchwork.kernel.org/patch/9075141/>.
Ideally, we should take both the patch posted to dw_mmc and this
revert. Since those will likely go through different trees, here I
describe behavior with the combos:
1. Just this revert: likely will fix rk3288-veyron eMMC on some devices
+ other cases; might break someone with a strange bootloader that
sets the phase to 0 or one that uses delay elements (pretty
unpredicable what would happen in that case).
2. Just dw_mmc patch: fixes everyone. Effectly the dw_mmc patch will
totally override the broken patch and fix everything.
3. Both patches: fixes everyone. Once dw_mmc is initting properly then
any defaults from the clock code doesn't mattery.

[emmc and sdmmc still work on all current boards in mainline after this
revert, so they should take precedence over any out-of-tree board that
will hopefully again get fixed with the better upcoming dw_mmc change.]

defined in DT by setting the 'native-mode' property appropriately.

sun4i_rgb_init() can fail, which results in TCON failing to bind.
In this case we need to do cleanup, specificly unregistering the
dotclock, which is regmap based, and the regmap is registered as
part of the sun4i_tcon_bind().
Failing to do so results in a NULL pointer reference when the CCF
tries to turn off unused clocks.

If simplefb was setup by our bootloader and enabled in the DT, we will have
a first framebuffer loaded in our system.
However, as soon as our DRM driver will load, it will reset the controller,
initialise it and, if the framebuffer emulation is enabled, register a
second framebuffer device.
This is obviously pretty bad, since the first framebuffer will be some kind
of a black hole, with memory still reserved that we can write to safely,
but not displayed anywhere.
Make sure we remove that framebuffer when we probe so we don't end up in
that situation.

Our pixel clock currently only tries to deal with the current parent rate.
While that works when the resolution is the same than the one already
program, or when we can compute directly the rate from the current parent
rate, it cannot work in most situation when we want to change the
frequency, and we end up with an improper pixel clock rate, which obviously
doesn't work as expected.
Ask our parent for all the possible dividers if it can reach that
frequency, and return the best parent rate to the clock framework so that
we can use it.

Since NAPI works by shutting down event interrupts when theres
work and turning them on when theres none, the net driver must
make sure that interrupts are disabled when it reschedules polling.
By calling napi_reschedule, the driver switches to polling mode,
therefor there should be no interrupt interference.
Any received packets will be handled in nps_enet_poll by polling the HW
indication of received packet until all packets are handled.

If CONFIG_IPV6=m, ip6_tnl_encap_add_ops/ip6_tnl_encap_del_ops
are in a module, but fou6.c can still be built-in, and that
obviously fails to link.
Also, if CONFIG_IPV6=y, but CONFIG_IPV6_TUNNEL=m or
CONFIG_IPV6_TUNNEL=n, the same problem happens for a different
reason.
This adds two new silent Kconfig symbols to work around both
problems:
- CONFIG_IPV6_FOU is now always set to 'm' if either CONFIG_NET_FOU=m
or CONFIG_IPV6=m
- CONFIG_IPV6_FOU_TUNNEL is set implicitly when IPV6_FOU is enabled
and NET_FOU_IP_TUNNELS is also turned out, and it will ensure
that CONFIG_IPV6_TUNNEL is also available.
The options could be made user-visible as well, to give additional
room for configuration, but it seems easier not to bother users
