Pulled, thanks a lot, Will.
These patches add the NWL host controller to the imx8mq and make use of it on
the Librem 5 Devkit enabling the built in MIPI DSI LCD panel.
I opted to add imx8mq internal ports and endpoints between nwl and lcdif to the
generic dtsi since those are SOC rather than board specific properties.

There are drivers which just need to get multiple interconnect paths,
request some predefined amounts of bandwidth and then just toggle the

The aim of this patch is simplify the above and to allow drivers to put

Use the standard l2c2x0 device tree bindings to enable data and
instruction prefetch on exynos4210 and exynos4412 and clear the
respective bits in the default l2c_aux_val. No other Exynos platform
relying on this default register value appears to be using the l2x0
cache.

The L310_PREFETCH_CTRL register bits 28 and 29 to enable data and
instruction prefetch respectively can also be accessed via the
L2X0_AUX_CTRL register. They appear to be actually wired together in
hardware between the registers. Changing them in the prefetch
register only will get undone when re
The L220_AUX_CTRL_NS_LOCKDOWN flag is set during the L2C enable
sequence. There is no need to set it in the default register value,
this was done before support for it was implemented in the code. It
is not set in the hardware initial value either.
Clean this up by removing this flag from the de

__SEQ_LOCKDEP() is an expression gate for the
seqcount_LOCKNAME_t::lock member. Rename it to be about the member,
not the gate condition.
Later (PREEMPT_RT) patches will make the member available for !LOCKDEP

Hi,
These are some minor cleanups that go on top of darwi's seqlock patches:
https://lkml.kernel.org/r/20200720155530.1173732-1-a.darw...@linutronix.de
It's mostly trimming excessive manual repetition and a few naming niggles.
The series has been exposed to 0-day for a while now, so I'm going
