As ap192k and julia cards are very similar, this change will hopefully
help reusing part of the juilia codec initialization code as is in the
ap192k card code. No behavior change.
|
|
The set_rate method switches the AK5385 and the AK4358 chips between
single-, double- or quad-speed modes depending on the host sample
rate. This suppresses aliasing noise in 96kHz and 192kHz sample
rates.
Help and testing by Andrey Oktyabrskiy <ano at bestmx.net>. Thanks!

This allows to hook card-specific codec initialization code
called when the sample rate is changed. As codecs follow host
clock, this method will be typically used to switch between
simple-speed to double-speed modes when necessary.
|
|
|
|
The new GPIO state doesn't set masked bits and matches the default
48kHz sampling rate. As the codec uses the host clock, this is a
no-op, but this way the code is less confusing.

This controller does not only support pinmuxing, but also includes
GPIO controller functionality. This is needed to e.g. turn on USB
VBus on the Turris Mox.

Because the RTC is still ticking it is theoretically possible for the
second to roll over while we are reading the clock. This is basically
impossible on real/practical hardware but is an interesting corner case
for e.g. a VM reading an emulated MC146818 during an exit to userspace.
This doesn't check *every* register, so if it takes you a multiple of
60 seconds to read the RTC this change won't help you. But you've got
bigger problems at that point.

late, after we enable interrupts. If the interrupt pin used for inteldrm(4)
is shared with another device, we may end up being called before the actual
interrup handler is installed resulting in a null-pointer dereference.
Fix this by adding an explicit check that the interrupt handler function
pointer has been set.

the controller has an i2c read operation that's almost exactly what we
want, except it only does 64 bytes at a time, so this is pretty simple.

the hotplug code doesn't need to do the same. Also the hotplug
code only configured a single bus and did that before the proper
allocation ran, so there was no chance for hotplugged ppb(4)s to
have children busses.

Reduce code clutter by removing the file name and line number output
from witness(4). Typically it is easy enough to locate offending locks
using the stack traces that are shown in lock order conflict reports.
Tricky cases can be tracked using sysctl kern.witness.locktrace=1 .
This patch additionally removes the witness(4) wrapper for mutexes.
Now each mutex implementation has to invoke the WITNESS_*() macros
in order to utilize the checker.

The marketing names in libdrm's amdgpu.ids are based on device id and
revision id. A single device id often maps to multiple marketing names
but the same codename so stick to codenames here. The marketing names
in amdgpu.ids also do not cover all the device ids amdgpu matches on.
Use the same codenames as amdgpu.

myx doesn't allow i2c writes, so you can only read whatever page
the firmware is already pointing at on device 0xa0. if you try to
read another page it will return ENXIO.
