When either of the normal or wakeup filter protocols are changed, refresh the corresponding scancode filter, i.e. try and set the same scancode filter with the new protocol. If that fails clear the filter instead. If no protocol was selected the filter is just cleared, and if no s_filter callback exists the filter is left unmodified. Similarly clear the filter mask when the filter is set if no protocol is currently selected. This simplifies driver code which no longer has to explicitly worry about modifying the filter on a protocol change. This also allows the change_wakeup_protocol callback to be omitted entirely if there is only a single available wakeup protocol at a time, since selecting no protocol will automatically clear the wakeup filter, disabling wakeup.

Add a wakeup_protocols sysfs file which controls the new rc_dev::enabled_protocols[RC_FILTER_WAKEUP], which is the mask of protocols that are used for the wakeup filter. A new RC driver callback change_wakeup_protocol() is called to change the wakeup protocol mask. Signed-off-by:

Only a single allowed and enabled protocol mask currently exists in struct rc_dev, however to support a separate wakeup filter protocol two of each are needed, ideally as an array. Therefore make both rc_dev::allowed_protos and rc_dev::enabled_protocols arrays, update all users to reference the first element (RC_FILTER_NORMAL), and add a couple more helper functions for drivers to use for setting the allowed and enabled wakeup protocols. We also rename allowed_protos to allowed_protocols while we're at it, which is more consistent with enabled_protocols. Signed-off-by:

James Hogan authored
The allowed and enabled protocol masks need to be expanded to be per filter type in order to support wakeup filter protocol selection. To ease that process abstract access to the rc_dev::allowed_protos and rc_dev::enabled_protocols members with inline functions. Signed-off-by:

James Hogan authored
Add generic scancode filtering of RC input events, and fall back to permitting any RC_FILTER_NORMAL scancode filter to be set if no s_filter callback exists. This allows raw IR decoder events to be filtered, and potentially allows hardware decoders to set looser filters and rely on generic code to filter out the corner cases. Signed-off-by:

On certain motherboards (mainly Intel NUC series) bios keeps the Nuvoton CIR device disabled at boot. This patch adds a call to kernel PNP layer to activate the device if it is not already activated. This will improve the chances of the PNP probe actually succeeding on Intel NUC platforms. Signed-off-by:

DViCO FusionHDTV7 device that use au0828 can fail to communicate with xc5000 using i2c interface because of high i2c clock speed - i2c clock stretching bug. It causes to fail xc5000 firmware loading normally at the current driver. Already this problem fixed as changing to low i2c clock speed at HVR-950q device, also DViCO FusionHDTV7 device can solve it as using low i2c clock speed - 20KHz. Signed-off-by:

Propagate errors returned by drivers from the s_filter callback back to userland when updating scancode filters. This allows userland to see when the filter couldn't be updated, usually because it's not a valid filter for the hardware. Previously the filter was being updated conditionally on success of s_filter, but the write always reported success back to userland. Reported-by:

Since the introduction of the new OMAP DSS DVI connector driver in commit 348077b1 ("OMAPDSS: Add new DVI Connector driver"), DVI outputs report a new display type of OMAP_DISPLAY_TYPE_DVI instead of OMAP_DISPLAY_TYPE_DPI. Handle the new type in the IRQ handler. Signed-off-by:

-
Hans Verkuil authored
Struct v4l2_subdev_edid and the VIDIOC_SUBDEV_G/S_EDID ioctls were specific for subdevices, but for hardware with a simple video pipeline you do not need/want to create subdevice nodes to just get/set the EDID. Move the v4l2_subdev_edid struct to v4l2-common.h and rename as v4l2_edid. Add the same ioctls to videodev2.h as well, thus allowing this API to be used with both video nodes and v4l-subdev nodes.
