[media] media.h: add support for IF-PLL video/sound decoder

Very old hardware may have an analog stage tuner. Those hardware
consists of a PLL that converts a RF signal into IF signals.

Depending on the hardware, those video IF signal can be
decoded directly by the bridge chipset. Most Conexant
chips (bt8x8, cx2388x, etc) have internally the decoders
for that. Yet, even on such hardware, the tuner may have
internally its own TV multi-standard decoder like tda9887.

The same happens with the audio IF signal, where some bridges
are capable of receiving it, while others require an external
IF-PLL sound decoder, like msp3400.

Those external IF-PLL audio and video decoders have their own
I2C address, and use different drivers to handle them. So, they're
mapped as different subdevices on Linux.

Thankfully, all modern hardware comes with an IC chip that
has both the RF and the IF stages on it, being capable of
decoding audio and video IF signals internally.

Yet, as we need to support drivers that can work with either
analog or silicon tuners, we need to add two entity types
for those old hardware.

[media] v4l2-mc.h: move tuner PAD definitions to this new header

The customer PC hardware can be shipped with lots of different
configurations, as vendors use to replace some of the chips on
their hardware along the time. All drivers that support such
devices are prepared to handle the hardware differences, using
their own auto-probing logic.

They do it in a way that number of inputs and outputs for a given
hardware type doesn't change.

Now that we're adding media controller capabilities to those drivers,
we need to standardize the number of inputs and outputs for each
hardware type, as we want to have a generic function at the V4L2
core that would create the links for the entities that are expected
on such hardware.

Such standard is already there for tuners, but tuner.h is not the
best place to store such data, as we'll need to add definitions also
for analog TV demodulators.

Also, we'll need a place to put a set of MC handling functions. So,
let's create a v4l2-mc.h to store such kind of definitions.

At least on Zotac CI321 ACPI provides an ioport range for the wake up part

Instead the ioport base address is set to another value already

Therefore set a new ioport base address only if the current ioport base
address is 0 (register reset default).

The need to use the existing base address instead of trying to set
an own one doesn't seem to be limited to this specific device as other
drivers like hwmon/nct6775 do it the same way.

This change was successfully tested on the mentioned device.
And the change should be generic enough to not break the driver for

[media] media: rc: raw: improve FIFO handling

The FIFO is used for ir_raw_event records, however for some historic
reason the FIFO is used on a per byte basis. IMHO this adds unneeded
complexity. Therefore set up the FIFO for ir_raw_event records.

This also allows to define the FIFO statically as part of
ir_raw_event_ctrl instead of having to allocate the FIFO dynamically.
In addition:

- When writing into the FIFO and it's full return ENOSPC instead of
  ENOMEM thus making it easier to tell between "FIFO full" and
  "Dynamic memory allocation failed" when the error is propagated to
  a higher level.
  Also add an error message.

- When reading from the FIFO check whether it's empty.
  This is not strictly needed here but kfifo_out is annotated
  "must check" anyway.

After power-up, the tvp5150 decoder is in a unknown state until the
RESETB pin is driven LOW which reset all the registers and restarts
the chip's internal state machine.

The init sequence has some timing constraints and the RESETB signal
can only be used if the PDN (Power-down) pin is first released.

So, the initialization sequence is as follows:

1- PDN (active-low) is driven HIGH so the chip is power-up
2- A 20 ms delay is needed before sending a RESETB (active-low) signal.
3- The RESETB pulse duration is 500 ns.
4- A 200 us delay is needed for the I2C client to be active after reset.

8 years agovmstat: Remove BUG_ON from vmstat_update
Christoph Lameter [Fri, 22 Jan 2016 16:46:14 +0000 (10:46 -0600)] 
vmstat: Remove BUG_ON from vmstat_update

If we detect that there is nothing to do just set the flag and do not
check if it was already set before.  Races really do not matter.  If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.

Since commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd.  This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up.  The VM_BUG_ON is therefore misleading and no more
appropriate.  Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly.  Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

MIPS: Move KVM specific opcodes into asm/inst.h

The header arch/mips/kvm/opcode.h defines a few extra opcodes which
aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM
specific about them, so lets move them into inst.h where they belong and
delete the header.

Note that mfmcz_op is renamed to mfmc0_op to match the instruction set
manual, and wait_op was already added to inst.h in commit b0a3eae2b943
("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.

MIPS: Break down cacheops.h definitions

Most of the cache op codes defined in cacheops.h are split into a 2-bit
cache identifier, and a 3-bit cache op code which does largely the same
thing semantically regardless of the cache identifier.

To allow the use of these definitions by KVM for decoding cache ops,
break the definitions down into parts where it makes sense to do so, and
add masks for the Cache and Op field within the cache op.

together to find the offset of the specific register in the mips_coproc,
