From 0204fe2a20da12ddae1b564712ceeebc55214f97 Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Tue, 1 Jun 2010 17:30:35 -0300 Subject: V4L/DVB: IR: add RC6 keymap for Windows Media Center Ed. remotes This is the RC6 keymap for the Windows Media Center Edition remotes that come bundled with MCE/eHome Infrared Remote transceivers. Tested with 3 different variants of the remote, but its possible there are still some additional keys missing, but its simple enough to add them in later... This patch also adds an IR_TYPE_ALL convenience macro to make life easier for receivers that support all IR protocols. v2: fix an erroneous comment that referred to imon devices Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab --- include/media/rc-map.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/media') diff --git a/include/media/rc-map.h b/include/media/rc-map.h index c78e99a435b..36ee280d42a 100644 --- a/include/media/rc-map.h +++ b/include/media/rc-map.h @@ -19,6 +19,9 @@ #define IR_TYPE_SONY (1 << 4) /* Sony12/15/20 protocol */ #define IR_TYPE_OTHER (1u << 31) +#define IR_TYPE_ALL (IR_TYPE_RC5 | IR_TYPE_NEC | IR_TYPE_RC6 | \ + IR_TYPE_JVC | IR_TYPE_SONY | IR_TYPE_OTHER) + struct ir_scancode { u32 scancode;

I've actually tested this in a tree w/all the lirc drivers queued up to be submitted for staging. I'm also reasonably sure that Andy Walls is going to need most of the ioctls anyway for his cx23888 IR driver work.

V4L/DVB: dib0700: break keytable into NEC and RC-5 variants Instead of having one big keytable with 2 protocols inside, break it into two separate tables, being one for NEC and another for RC-5 variants, and properly identify what variant should be used at the boards entries.

a method to v4l2_sudev_core_ops to allow bridge drivers to manage what signal pads/functions are routed out to multiplexed IO pins on a pin by pin basis. The interface also allows specifying initial output settings for pins and disabling an IO pin altogether.

Presently, the in-kernel keymap doesn't work, as the stock Streamzap remote uses an RC-5-like, but not-quite-RC-5 protocol, which the in-kernel RC-5 decoder doesn't cope with. The remote can be used right now with the lirc bridge driver though, and other remotes (at least an RC-6(A) MCE remote) work perfectly with the driver. I'll take a look at making the existing RC-5 decoder cope with this odd duck, possibly implement another standalone decoder engine, or just throw up my hands and say "meh, use lirc"... But the driver itself should be perfectly sound. Remaining items on the streamzap TODO list: - add LIRC_SET_REC_TIMEOUT-alike support - add LIRC_GET_M{AX,IN}_TIMEOUT-alike support - add LIRC_GET_REC_RESOLUTION-alike support All of the above should be trivial to add. There are patches pending to add this support to ir-core from Maxim Levitsky, and I'll take care of these once his patches get integrated. None of them are currently essential though.

Note that this patch moves some of the control support that used to be in v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl struct anymore, which makes it more general. The remainder of v4l2-ctrls.c is all new. Highlights include: - No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL, S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers or subdevs. New wrapper functions are provided that can just be plugged in. Once everything has been converted these wrapper functions can be removed as well. - When subdevices are added their controls can be automatically merged with the bridge driver's controls. - Most drivers just need to implement s_ctrl to set the controls. The framework handles the locking and tries to be as 'atomic' as possible. - Ready for the subdev device nodes: the same mechanism applies to subdevs and their device nodes as well. Sub-device drivers can make controls local, preventing them from being merged with bridge drivers. - Takes care of backwards compatibility handling of VIDIOC_S_CTRL and VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent. CTRL_CLASS controls are automatically added.
