The temp_to_code function will return 0 when we set the temperature to a
invalid value (e.g. 61C, 62C, 63C), that's unpractical. This patch

The DT binding for tildc is not consistent with the driver code: there
are two options - 'max-width' and 'max-pixelclock' specified in the
documentation which are parsed as 'ti,max-width' and
'ti'max-pixelclock' respectively.
Make the driver code consistent with the binding.

Hi.
ADI_INIT_DELAY/ADI_DATA_DELAY doesn't have to be exact, and a longer
sleep doesn't matter. In the initilization sequence - first chunk of
your patch - a way too long delay could in theory make the device fail
to initialize. What's critical is that the mdelay() calls are precise.
One day I'll

It turns out that the deadlock that I found last week was already implicitly
fixed during the lock->owner redesign, by checking the WAITERS bit in the
w/w lock fast path. However, since I had already started looking into
sorting the wait list, here goes.
The basic idea is to make sure that:

Add regular waiters in stamp order. Keep adding waiters that have no
context in FIFO order and take care not to starve them.
While adding our task as a waiter, back off if we detect that there is a
waiter with a lower stamp in front of us.
Make sure to call lock_contended e

Check the current owner's context once against our stamp. If our stamp is
lower, we continue to spin optimistically instead of backing off.
This is correct with respect to deadlock detection because while the

We will add a new field to struct mutex_waiter. This field must be
initialized for all waiters if any waiter uses the ww_use_ctx path.
So there is a trade-off: Keep ww_mutex locking without a context on the
faster non-use_ww_ctx path, at the cost of adding the initializatio

Lock stealing is less beneficial for w/w mutexes since we may just end up
backing off if we stole from a thread with an earlier acquire stamp that
already holds another w/w mutex that we also need. So don't spin
optimistically unless we are sure that there is no other waiter

Help catch cases where mutex_lock is used directly on w/w mutexes, which
otherwise result in the w/w tasks reading uninitialized data.

While adding our task as a waiter, detect if another task should back off
because of us.
With this patch, we establish the invariant that the wait list contains
at most one (sleeping) waiter with ww_ctx->acquired > 0, and this waiter
will be the first waiter with a context.
From: Nicolai Hähnle
The wait list is sorted by stamp order, and the only waiting task that may
have to back off is the first waiter with a context.
The regular slow path does not have to wake any other tasks at all, since
all other waiters that would have to back off were either woken up when
