Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.
As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.

[ Upstream commit 287422a95fe28e05c1952de0472e0dfdffa6caae ]
I'm embarassed to say that even though I've touched
vop_crtc_mode_fixup() twice and I swear I tested it, there's still a
stupid glaring bug in it. Specifically, on veyron_minnie (with all
the latest display timings) we want to be setting our pixel clock to
66,666,666.67 Hz and we tell userspace that's what we set, but we're
actually choosing 66,000,000 Hz. This is confirmed by looking at the
clock tree.
The problem is that in drm_display_mode_from_videomode() we convert
from Hz to kHz with:
dmode->clock = vm->pixelclock / 1000;
...and drm_display_mode_from_videomode() is called from panel-simple
when we have an "override_mode" like we do on veyron_minnie. See
commit 123643e5c40a ("ARM: dts: rockchip: Specify
rk3288-veyron-minnie's display timings").
...so when the device tree specifies a clock of 66666667 for the panel
then DRM translates that to 66666000. The clock framework will always
pick a clock that is _lower_ than the one requested, so it will refuse
to pick 66666667 and we'll end up at 66000000.
While we could try to fix drm_display_mode_from_videomode() to round
to the nearest kHz and it would fix our problem, it wouldn't help if
the clock we actually needed was 60,000,001 Hz. We could
alternatively have DRM always round up, but maybe this would break
someone else who already baked in the assumption that DRM rounds down.
Specifically note that clock drivers are not consistent about whether
they round up or round down when you call clk_set_rate(). We know how
Rockchip's clock driver works, but (for instance) you can see that on
most Qualcomm clocks the default is clk_rcg2_ops which rounds up.
Let's solve this by just adding 999 Hz before calling
clk_round_rate(). This should be safe and work everywhere. As
discussed in more detail in comments in the commit, Rockchip's PLLs
are configured in a way that there shouldn't be another PLL setting
that is only a few kHz off so we won't get mixed up.
NOTE: if this is picked to stable, it's probably easiest to first pick
commit 527e4ca3b6d1 ("drm/rockchip: Base adjustments of the mode based
on prev adjustments") which shouldn't hurt in stable.

removed old omap3 clock framework aliases but caused omap3-rom-rng to

Based on discussions on the mailing list it was requested by Tero Kristo
that it would be best to fix this issue by probing omap3-rom-rng using
device tree to provide a proper clk property. The other option would be
to add back the missing clock alias, but that does not help moving things
forward with removing old legacy platform_data.
Let's also add a proper device tree binding and keep it together with
the fix.

commit c3594559f49c601d410dee4b767c3536a5535bfd upstream.
When downloading the reserved page, the first page always contains
a beacon for the firmware to reference. For non-beaconing modes such
as station mode, also put a blank skb with length=1.
And for the beaconing modes, driver will get a real beacon with a
length approximate to the page size. But as the beacon is always put
at the first page, it does not need a tx_desc, because the TX path
will generate one when TXing the reserved page to the hardware. So we
could allocate a buffer with a size smaller than the reserved page,
when using memcpy() to copy the content of reserved page to the buffer,
the over-sized reserved page will violate the kernel memory.
To fix it, add the tx_desc before memcpy() the reserved packets to
the buffer, then we can get SKBs with correct length when counting
the pages in total. And for page 0, count the extra tx_desc_sz that
the TX path will generate. This way, the first beacon that allocated
without tx_desc can be counted with the extra tx_desc_sz to get
actual pages it requires.

commit a4e55ccd4392e70f296d12e81b93c6ca96ee21d5 upstream.
snoop_file_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.
Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.

commit 4194b583c104922c6141d6610bfbce26847959df upstream.
If the DTB for a device with an RZ/A2 SoC lacks a device node for the
BSID register, the ID validation code falls back to using a register at
address 0x0, which leads to undefined behavior (e.g. reading back a
random value).
This could be fixed by letting fam_rza2.reg point to the actual BSID
register. However, the hardcoded fallbacks were meant for backwards
compatibility with old DTBs only, not for new SoCs. Hence fix this by
validating renesas_family.reg before using it.

commit c9e753767a9c75d2044fb7343950a6a992d34a16 upstream.
Interrupts that don't have an associated wake event or GPIO wake events
end up with an associate IRQ chip that is NULL and which causes IRQ code
to crash. This is because we don't implicitly set the parent IRQ chip by
allocating the interrupt at the parent. However, there really isn't a
corresponding interrupt at the parent, so we need to work around this by
setting the special no_irq_chip as the IRQ chip for these interrupts.

moved it from the normal kernel distro path, removed the modules, stoped
the kvm guest, and then installed it manually, etc.

commit 38a2204f5298620e8a1c3b1dc7b831425106dbc0 upstream.
The legacy client tracking infrastructure of nfsd makes use of MD5 to
derive a client's recovery directory name. As the nfsd module doesn't
declare any dependency on CRYPTO_MD5, though, it may fail to allocate
the hash if the kernel was compiled without it. As a result, generation
of client recovery directories will fail with the following error:
NFSD: unable to generate recoverydir name
The explicit dependency on CRYPTO_MD5 was removed as redundant back in
6aaa67b5f3b9 (NFSD: Remove redundant "select" clauses in fs/Kconfig
2008-02-11) as it was already implicitly selected via RPCSEC_GSS_KRB5.
This broke when RPCSEC_GSS_KRB5 was made optional for NFSv4 in commit
df486a25900f (NFS: Fix the selection of security flavours in Kconfig) at
a later point.
