Add the capability to encode NEC scancodes as raw events. The scancode_to_raw is pretty much taken from the img-ir NEC filter() callback, and modulation uses the pulse distance helper added in a previous commit. Signed-off-by:

Add the capability to encode RC-6 and RC-6A scancodes as raw events. The Manchester modulation helper is used several times with various timings so that RC-6 header preamble, the header, header trailing bit and the data itself can be modulated correctly. Signed-off-by:

Add the capability to encode RC-5, RC-5X and RC-5-SZ scancodes as raw events. The Manchester modulation helper is used, and for RC-5X it is used twice with two sets of timings, the first with a short trailer space for the space in the middle, and the second with no leader so that it can continue the space. The encoding in RC-5-SZ first inserts a pulse and then simply utilizes the generic Manchester encoder available in rc-core. Signed-off-by:

Add a callback to raw ir handlers for encoding and modulating a scancode to a set of raw events. This could be used for transmit, or for converting a wakeup scancode to a form that is more suitable for raw hardware wake up filters. Signed-off-by:

Now that we can select the exact variant of the protocol for wakeup filter, the winbond-cir can use the wakeup filter rather than module parameters. Signed-off-by:
-
Sean Young authored
There are two different encodings used for nec32: - The ir-nec-decoder.c decoder treats it as 32 bit msb first. - The img-ir decoder/encoder, winbond wakeup, dib0700, ir-ctl userspace, treat nec32 analogous to necx and nec: 4 bytes, each lsb first. So this format reverses the 4 bytes. There are arguments to be had for both formats, but we should not use different formats in different parts of the kernel. Selecting the second format introduces the least code churn. It does mean that the TiVo keymap needs updating. This change was submitted before as "18bc1744 [media] media: rc: change 32bit NEC scancode format", which was reverted because it was unclear what scancode rc drivers produce. There are now more examples of drivers which produce nec32 in lsb format. The TiVo keymap is verified against the Nero Liquid TiVo remote. The keymap is not for the Tivo DVR remote, which uses rc-5.

We need to valdiate that scancodes are valid for their protocol; an incorrect necx scancode could actually be a nec scancode, for example. Signed-off-by:

For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used. Signed-off-by:

There are many variants of extended rc5. This implements the 20 bit version. Signed-off-by:
-
Sean Young authored
The 2nd stop bit in rc5 is reused as an inverted 6th command bit in 20 bits rc5x. Currently the rc5x decoder sets the 6th command bit as an inverted duplicate of the lowest system bit; as a result we do not have all the command bits. Note that there are no rc5x keymaps present. Signed-off-by:

Both the iguanair and the technotrend usb ir do not do any timeout handling in hardware, so timeout is entirely done in ir_raw_event_store_with_filter(). Any sensible timeout value will do, so allow it to be set using LIRC_SET_REC_TIMEOUT. Signed-off-by:
-
Sean Young authored
No timeout is generated by serial_ir since the port only generates interrupts on edges. Some IR protocols like rc6 and rc5 need a trailing space or timeout so they know there are no more bits coming. Without it, the current key will only be reported once some more IR occurs. Signed-off-by:

I think we can get rid of the spinlock protecting the kthread from being interrupted by a wakeup in certain parts. Even with the current implementation of the kthread the only lost wakeup scenario could happen if the wakeup occurs between the kfifo_len check and setting the state to TASK_INTERRUPTIBLE. In the changed version we could lose a wakeup if it occurs between processing the fifo content and setting the state to TASK_INTERRUPTIBLE. This scenario is covered by an additional check for available events in the fifo and setting the state to TASK_RUNNING in this case. In addition the changed version flushes the kfifo before ending when the kthread is stopped. With this patch we gain: - Get rid of the spinlock - Simplify code - Don't grep / release the mutex for each individual event but just once for the complete fifo content. This reduces overhead if a driver e.g. triggers processing after writing the content of a hw fifo to the kfifo. Signed-off-by:

Sakari Ailus authored
The media_entity_pipeline_start() and media_entity_pipeline_stop() functions are renamed as media_pipeline_start() and media_pipeline_stop(), respectively. The reason is two-fold: the pipeline struct is, rightly, already called media_pipeline (rather than media_entity_pipeline) and what this really is about is a pipeline. A pipeline consists of entities --- and, well, other objects embedded in these entities. As the pipeline object will be in the future moved from entities to pads in order to support multiple pipelines through a single entity, do the renaming now. Similarly, functions operating on struct media_entity_graph as well as the struct itself are renamed by dropping the "entity_" part from the prefix of the function family and the data structure. The graph traversal which is what the functions are about is not specifically about entities only and will operate on pads for the same reason as the media pipeline. The patch has been generated using the following command: git grep -l media_entity |xargs perl -i -pe ' s/media_entity_pipeline/media_pipeline/g; s/media_entity_graph/media_graph/g' And a few manual edits related to line start alignment and line wrapping.

There's a sanity check for the stream count remaining positive or zero on error path, but instead of performing the check on the traversed entity it is performed on the entity where traversal ends. Fix this. Fixes: commit 3801bc7d ("[media] media: Media Controller fix to not let stream_count go negative") Signed-off-by:

Adds PLP ID filtering for DVB-T2. It is untested as I don't have any signal having PLP ID other than 0. There is only 2 extra registers, 0x32 and 0x36 on bank2, that are programmed for DVB-T2 but not for DVB-T and all the rest are programmed similarly - so it is likely PLP. Pridvorov reported successfully testing it in Russia with m-PLP streams, on both Vladivostok and Moskow. Tested-by:

I am getting the following warning when I build kernel 4.9-git on my PowerBook G4 with a 32-bit PPC processor: AS arch/powerpc/kernel/misc_32.o arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef] This problem is evident after commit 989cea5c ("kbuild: prevent lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an error that has been in the code since 2005 when this source file was created. That was with commit 9994a338 ("powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S"). The offending line does not make a lot of sense. This error does not seem to cause any errors in the executable, thus I am not recommending that it be applied to any stable versions. Thanks to Nicholas Piggin for suggesting this solution.

The timer type simplifications caused a new gcc warning: drivers/base/power/domain.c: In function ‘genpd_runtime_suspend’: drivers/base/power/domain.c:562:14: warning: ‘time_start’ may be used uninitialized in this function [-Wmaybe-uninitialized] elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start)); despite the actual use of "time_start" not having changed in any way. It appears that simply changing the type of ktime_t from a union to a plain scalar type made gcc check the use. The variable wasn't actually used uninitialized, but gcc apparently failed to notice that the conditional around the use was exactly the same as the conditional around the initialization of that variable. Add an unnecessary initialization just to shut up the compiler. Signed-off-by:
