The carrier detect return value is never used on nuvoton driver:
drivers/media/rc/nuvoton-cir.c: In function 'nvt_process_rx_ir_data':
drivers/media/rc/nuvoton-cir.c:623:6: warning: variable 'carrier' set but not used [-Wunused-but-set-variable]
Also, this would be called only if a boolean variable is enabled,
but there's no condition that enables it inside the driver. So,
comment the carrier detection code, as it might be useful later,
and remove the unused glue code.

The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.
Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.
Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.
Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).
The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).
This patch separate the different usages in preparation for
upcoming patches.
Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.
The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.

"carrier" comes from a get_user() in ir_lirc_ioctl(). We need to test
that it's not zero before using it as a divisor. It might have been
nice to test for this ir_lirc_ioctl() but the mceusb driver uses zero to
disable carrier modulation.
The bug in redrat3 is a little more subtle. The ->carrier is passed to
mod_freq_to_val() which uses it as a divisor.

fintek-cir, ite-cir and nuvoton-cir may try to free an I/O region
and/or IRQ handler that was never allocated after a failure in their
respective probe functions. Add and use separate labels on the
failure path so they will do the right cleanup after each possible
point of failure.

An early registration of an ISR was causing a crash to several users (for
example, with the ite-cir driver: http://bugs.launchpad.net/bugs/972723).
The reason was that IRQs were being triggered before a driver
initialisation was completed.
This patch fixes this by moving the invocation to request_irq() and to
request_region() to a later stage on the driver probe function.

The nuvoton-cir driver was storing up consecutive pulse-pulse and
space-space samples internally, for no good reason, since
ir_raw_event_store_with_filter() already merges back to back like
samples types for us. This should also fix a regression introduced late
in 3.0 that related to a timeout change, which actually becomes correct
when coupled with this change. Tested with RC6 and RC5 on my own
nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky
behavior in 3.0 due to the timeout change.

- Set a default timeout (matching mceusb.c) and use
ir_raw_event_store_with_filter, which leads to better behavior when
using lirc userspace decoding with this hardware
- Fill in rx_resolution with the value we're using here (50us)
- Wire up input phys and device parent pointer
- Use device_init_wakeup() instead of device_set_wakeup_*()

Thanks to some excellent investigative work by Douglas Clowes, it was
uncovered that the older w83667hg Nuvoton chip functions with this
driver after actually enabling the CIR function via its multi-function
chip config register. The CIR and CIR wide-band sensor enable bits are
just in a different place on this hardware, so we only poke register
0x27 on 677 hardware now, and we poke register 0x2c on the 667 now.

There are additional chip IDs that report a PNP ID of NTN0530, which we
were refusing to load on. Instead, lets just warn if we encounter an
unknown chip, as there's a chance it will work just fine.
Also, expand the list of known hardware to include both an earlier and a
later generation chip that this driver should function with. Douglas has
an older w83667hg variant, that with a touch more work, will be
supported by this driver, and Lutz has a newer w83677hg variant that
works without any further modifications to the driver.

The CIR Wake FIFO is 67 bytes long, but the stock remote appears to only
populate 65 of them. Limit comparison to 65 bytes, and wake from suspend
works a whole lot better (it wasn't working at all for most folks).
Fix based on comparison with the old lirc_wb677 driver from Nuvoton,

The Remote Controller subsystem is meant to be used not only by Infra Red
but also for similar types of Remote Controllers. The core is not specific
to Infra Red. As such, rename:
- ir-core.h to rc-core.h
- IR_CORE to RC_CORE
- namespace inside rc-core.c/rc-core.h
To be consistent with the other changes.

This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.
This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.
The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()
