Rather than having special code cases for diagonal mouse movements, extend the general purpose code used for the cardinal directions to handle arbitrary (x,y) deltas. The deltas themselves are stored in translation table's "code" field; this is also progress toward the goal of eliminating the "value" element entirely. Signed-off-by:

It's not necessary, and since both events happen "at the same time" in response to a single input event, the input device framework prefers not to have it there. (It's not a big deal one way or the other, but deleting cruft is generally a good thing.) Signed-off-by:

An input report is 4 bytes long, but there are only 12 bits of actual payload. The 4 bytes are: data[0] = 0x14 data[1] = data[2] + data[3] + 0xd5 (a checksum byte) data[2] = the raw scancode (plus toggle bit in msbit) data[3] = channel << 4 (the low 4 bits must be zero) Ignore reports with a bad checksum.

The hole point of IR_dprintk() is that, once a level is given at debug parameter, all enabled IR parsers will show their debug messages. While converting it to dynamic_printk might be a good idea, right now it just makes very hard to debug the drivers, as one needs to both pass debug=1 or debug=2 to rc-core and to use the dynamic printk to enable all the desired lines. That doesn't make sense! So, revert to the old way, as a single line is changed, and the debug parameter will now work as expected. Signed-off-by:

Once upon a time the radio-miropcm20 driver had RDS support. However, after some internal kernel changes that support was removed. Now that we have a nice RDS API I have been working on adding back this support. It has been tested with the si4713 RDS transmitter and it is working quite nicely. Signed-off-by:

Hans Verkuil authored
The radio-miropcm20 driver has firmware that decodes the RDS signals. So in that case the RDS data becomes available in the form of controls. Add support for these controls to the control framework, allowing the miro driver to use them. Signed-off-by:

Hans Verkuil authored
The si4713 supports several RDS features not yet implemented in the driver. This patch adds the missing RDS functionality to the list of RDS controls. The ALT_FREQS control is a compound control containing an array of up to 25 (the maximum according to the RDS standard) frequencies. To support that the V4L2_CTRL_TYPE_U32 was added. Signed-off-by:

A lot of work was done in vb2 to regulate how drivers and the vb2 core handle buffer ownership, but inexplicably the videobuf2-core.h comments were never updated. Do so now. The same was true for the replacement of the -ENOBUFS mechanism by the min_buffers_needed field. Signed-off-by:

Rather than always having to use a v4l2_ext_control struct to set a control value from within a driver, switch to just setting the new value. This is faster and it makes it possible to set more complex types such as a string control as is added by this patch. Signed-off-by:

Now that the protocol is part of the scancode, it is pretty easy to merge the rc5 and streamzap decoders. An additional advantage is that the decoder is now stricter as it waits for the trailing silence before determining that a command is a valid rc5/streamzap command (which avoids collisions that I've seen with e.g. Sony protocols).

The basic API of rc-core used to be: dev = rc_allocate_device(); dev->x = a; dev->y = b; dev->z = c; rc_register_device(); which is a pretty common pattern in the kernel, after the introduction of protocol arrays the API looks something like: dev = rc_allocate_device(); dev->x = a; rc_set_allowed_protocols(dev, RC_BIT_X); dev->z = c; rc_register_device(); There's no real need for the protocols to be an array, so change it back to be consistent (and in preparation for the following patches).

This driver codes the two address bytes in reverse order when compared to the other drivers, so make it consistent (and update the keymap, note that the result is a prefix change from 0x6b86 -> 0x866b, and the latter is pretty common among the NECX keymaps. While not conclusive, it's still a strong hint that the change is correct). Signed-off-by:

Right now the protocol information is not preserved, rc-core gets handed a scancode but has no idea which protocol it corresponds to. This patch (which required reading through the source/keymap for all drivers, not fun) makes the protocol information explicit which is important documentation and makes it easier to e.g. support multiple protocols with one decoder (think rc5 and rc-streamzap). The information isn't used yet so there should be no functional changes. [m.chehab@samsung.com: rebased, added cxusb and removed bad whitespacing] Signed-off-by:

the RC RX packet is defined as: struct dib0700_rc_response { ... u8 not_system; u8 system; ... u8 data; u8 not_data; The NEC protocol transmits in the order: system not_system data not_data Note that the code defines the NEC extended scancode as: scancode = be16_to_cpu(poll_reply->system16) << 8 | poll_reply->data; i.e. scancode = poll_reply->not_system << 16 | poll_reply->system << 8 | poll_reply->data; Which, if the order *is* reversed, would mean that the scancode that gets defined is in reality: scancode = poll_reply->system << 16 | poll_reply->not_system << 8 | poll_reply->data; Which is the same as the order used in drivers/media/rc/ir-nec-decoder.c. This patch changes the code to match my assumption (the generated scancode should, however, not change). [m.chehab@samsung.com: rebased and fixed the decoding error message] Signed-off-by:

The bt8xx driver does RC5 decoding for Nebula digi hardware, but includes some pointless limitations (both start bits must be one, the device/address/system must be 0x00). Remove those limitations and update the keymap to use the full RC5 scancode (fortunately the 0x00 address means that this is perfectly backwards compatible). Signed-off-by:

The programmed frequency on xc4000 is not the middle frequency, but the initial frequency on the bandwidth range. However, the DVB API works with the middle frequency. This works fine on set_frontend, as the device calculates the needed offset. However, at get_frequency(), the returned value is the initial frequency. That's generally not a big problem on most drivers, however, starting with changeset 6fe1099c, the frequency drift is taken into account at dib7000p driver. This broke support for PCTV 340e, with uses dib7000p demod and xc4000 tuner. Cc: stable@vger.kernel.org Signed-off-by:
