When the adapter is removed the cec_delete_adapter() call attempts to set the physical address to INVALID by calling __cec_s_phys_addr() and so disabling the adapter. However, __cec_s_phys_addr checks if the device node was unregistered and just returns in that case. This means that the adap_enable callback is never called with 'false' to disable the CEC adapter. Most drivers don't care, but some need to do cleanup here. Change the test so the adapter is correctly disabled, even when the device node is unregistered. Signed-off-by:

This Kaffeine's BZ: https://bugs.kde.org/show_bug.cgi?id=374693 affects SkyStar S2 PCI DVB-S/S2 rev 3.3 device. It could be due to a Kernel bug. While checking the Isil 6421, comparing with its manual, available at: http://www.intersil.com/content/dam/Intersil/documents/isl6/isl6421a.pdf It was noticed that, if the output load is highly capacitive, a different approach is recomended when energizing the LNBf. Also, it is possible to detect if a current overload is happening, by checking an special flag. Add support for it. Tested on Skystar S2. Changes respect override_or option so should still work fine on cx88 based cards which disable dynamic current limit. Changes since v1: v2 - fixed incorrect checking of i2c return values v3 - fix if logic to check if dcl needs re-enabling - respect override_or values which aim to disable dcl - only do long sleep on overload if dcl enabled - add short sleep before re-enabling dcl - only check overload and potentially return EINVAL if device is on v4 - revert v3 sleep logic changes to remove tuning delays Signed-off-by:

The 'Press and Hold' operation was not correctly implemented, in particular the requirement that the repeat doesn't start until the second identical keypress arrives. The REP_DELAY value also had to be adjusted (see the comment in the code) to achieve the desired behavior. The 'enabled_protocols' field was also never set, fix that too. Since CEC is a fixed protocol the driver has to set this field. Signed-off-by:

Since commit 12749b198fa4 ("[media] rc: saa7134: add trailing space for timely decoding"), the workaround of inserting reset events is no longer needed. Note that the initial reset is not needed either; other rc-core drivers that don't use ir_raw_event_store_edge() never call this at all. Verified on a HVR-1150 and Raspberry Pi.

Sean Young authored
The gpio-ir-recv driver adds timeouts which the saa7134 lacks; this causes keypress not to arrive, and to only arrive once more IR is received. This is what the commit below calls "ghost keypresses", and that commit does not solve the issue completely. This makes the IR on the HVR-1150 much more reliable and responsive.

Sean Young authored
The gpio-ir-recv driver does many wakeups (once per edge); the saa7134 driver has special handling to only wakeup 15ms after the first edge. Make this part of rc-core so gpio-ir-recv also benefits from this (so a rc-5 keypress now causes 3 wakeups rather than 24). Signed-off-by:

Transmit support in this driver was never tested and based on the code it can't work. Just one example: The buffer provided to nvt_tx_ir holds unsigned int values in micro seconds: First value is for a pulse, second for a pause, etc. Bytes in this buffer are copied as-is to the chip FIFO what can't work as the chip-internal format is totally different. See also conversion done in nvt_process_rx_ir_data. Even if we would try to fix this we have the issue that we can't test it. There seems to be no device on the market using IR transmit with one of the chips supported by this driver. To facilitate maintenance of the driver I'd propose to remove the rudimentary transmit support. Signed-off-by:

Remove unnecessary static on local variable delt. Such variable is initialized before being used, on every execution path throughout the function. The static has no benefit and, removing it reduces the code size. This issue was detected using Coccinelle and the following semantic patch: @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; In the following log you can see the difference in the code size. Also, there is a significant difference in the bss segment.

This patch adds driver for CIR controller on MT7622 SoC. It has similar handling logic as the previously MT7623 does, but there are some differences in the register and field definition. So for ease portability and maintenance, those differences all are being kept inside the platform data as other drivers usually do. Currently testing successfully on NEC and SONY remote controller.

This patch is the preparation patch in order to adapt into various hardware through adding platform data which holds specific characteristics and differences among MediaTek supported CIR devices instead of the old way defining those data in the static way as macro has. And the existing logic would be slightly changed to operate on those data which the actual device depends on. Signed-off-by:

The NEC decoder and the Sanyo decoders check if dev->keypressed is true before calling rc_repeat (without holding dev->keylock). Meanwhile, the XMP and JVC decoders do no such checks. This patch makes sure all users of rc_repeat() do so consistently by removing extra checks in NEC/Sanyo and modifying the check a bit in rc_repeat() so that no input event is generated if the key isn't pressed.

The configuration of the pipeline and entities directly affects the inputs required to each entity for the partition algorithm. Thus it makes sense to involve those entities in the decision making process. Extend the entity ops API to provide an optional .partition() operation. This allows entities that affect the partition window to adapt the window based on their configuration. Entities implementing this operation must update the window parameter in place, which will then be passed up the pipeline. This creates a process whereby each entity describes what is required to satisfy the required output to its predecessor in the pipeline. Signed-off-by:
