We already add a trailing space, this wasn't doing anything useful, and actually confused lirc userspace a bit. Rip it out. CC: Chris Dodge <chris@redrat.co.uk> CC: Andrew Vincer <andrew.vincer@redrat.co.uk> CC: Stephen Cox <scox_nz@yahoo.com> Signed-off-by:

This is a custom IR protocol decoder, for the RC-6-ish protocol used by the Microsoft Remote Keyboard, apparently developed internally at Microsoft, and officially dubbed MCIR-2, per their March 2011 remote and transceiver requirements and specifications document, which also touches on this IR keyboard/mouse device. Its a standard keyboard with embedded thumb stick mouse pointer and mouse buttons, along with a number of media keys. The media keys are standard RC-6, identical to the signals from the stock MCE remotes, and will be handled as such. The keyboard and mouse signals will be decoded and delivered to the system by an input device registered specifically by this driver. Successfully tested with multiple mceusb-driven transceivers, as well as with fintek-cir and redrat3 hardware. Essentially, any raw IR hardware with enough sampling resolution should be able to use this decoder, nothing about it is at all receiver-hardware-specific. This work is inspired by lirc_mod_mce: The documentation there and code aided in understanding and decoding the protocol, but the bulk of the code is actually borrowed more from the existing in-kernel decoders than anything. I did recycle the keyboard keycode table, a few defines, and some of the keyboard and mouse data parsing bits from lirc_mod_mce though. Special thanks to James Meyer for providing the hardware, and being patient with me as I took forever to get around to writing this. callback routine to ensure we don't get any stuck keys, and used symbolic names for the keytable. Also cc'ing Florian this time, who I believe is the original mod-mce author... CC: Florian Demski <fdemski@users.sourceforge.net> Signed-off-by:

It is useless. There is only one physical I2C-adapter. 2nd adapter was added originally due to some plans for allowing only one demod to access bus at time. But I never implemented proper locking... Signed-off-by:

That's this tuner: The credit card sized remote more or less works if I set remote=4, so I added the hash to get it autodetected. (`more or less' there meaning sometimes buttons are `stuck on repeat', i.e. ir-keytable -t keeps repeating the same scancode until i press another button.) Signed-off-by:

In drivers/media/dvb/frontends/drxd_hard.c::load_firmware() I see 3 small issues: 1) When the 'fw' variable goes out of scope we'll leak the memory allocated to it by request_firmware() by neglecting to call release_firmware(). 2) After a successful request_firmware() we allocate fw->size bytes of memory using kzalloc() only to immediately overwrite all that memory with memcpy(), so asking for zeroed memory seems like wasted effort - just use kmalloc(). 3) In one of the error messages "no memory" lacks a space and is written as "nomemory". This patch fixes all 3 issues. Signed-off-by:

Microsoft's Windows Media Center specification and requirements doc from 2011.03.18 now refers to the former Power Toggle button as the Sleep Toggle, and recommends using a new moon sleep icon for it. Its the same key, but its apparently always been meant to put the system to sleep, not power it off. Adjust accordingly. While we're here, lets also remove the duplicate KEY_PLAYPAUSE entry.

The Marvell camera core can support all three videobuf2 buffer modes, which is slick, but it also requires that all three modes be built and present, even though only one is likely to be used. This patch allows the supported modes to be selected at configuration time, reducing the footprint of the driver. Prior to this patch, the MMP camera driver looked like this: mmp_camera 19092 0 videobuf2_core 15542 1 mmp_camera videobuf2_dma_sg 3173 1 mmp_camera videobuf2_dma_contig 2188 1 mmp_camera videobuf2_vmalloc 1718 1 mmp_camera videobuf2_memops 2100 3 videobuf2_dma_sg,videobuf2_dma_contig,videobuf2_vmalloc Afterward, instead, with scatter/gather only configured: mmp_camera 16021 0 videobuf2_core 15542 1 mmp_camera videobuf2_dma_sg 3173 1 mmp_camera videobuf2_memops 2100 1 videobuf2_dma_sg The total goes from 43,813 bytes to 36,836. The emphasis has been on simplicity and minimal #ifdef use rather than on squeezing out every possible byte of code. For configuration, the driver simply looks at which videobuf2 modes have been configured in and supports them all; it's simplistic but should be good enough. The cafe driver is set to support vmalloc and dma-contig; mmp supports only dma-sg, since that's the only mode that really makes sense to use. Signed-off-by:

This code shows signs of having been mucked with over the last five years or so; things were kind of mixed up. This patch reorders functions into a more rational organization which, with luck, will facilitate making the buffer modes selectable at configuration time. Code movement only: no functional changes here. Signed-off-by:

The third parameter of module_param is supposed to represent sysfs file permissions. A value of "1" leads to the following: $ ls -l /sys/module/radio_tea5764/parameters/ total 0 I am changing it to "0" to align with the other module parameters in this driver. Signed-off-by:

Based on the work of John Newbigin, Davor Emard and others who contributed on the mailing lists. The previous 'support' for this card was a partial merge of John's changes that, as far as I can tell, never actually got the thing working (no DVB-T, analog tuner not initialised). Initialise the analog tuner properly and hook up the DVB tuner and demodulator. DVB-T and analog now work (though I can't tune every DVB channel, but I think there's an issue with the aerial and signal boosters here that is causing me problems). Signed-off-by:

The QAM standard is set using this scu_command: SCU_RAM_COMMAND_STANDARD_QAM | SCU_RAM_COMMAND_CMD_DEMOD_SET_PARAM The driver implements a version that has 4 parameters, however, Terratec H5 needs to break this into two separate commands, otherwise, DVB-C doesn't work. With this fix, scan is now properly working and getting the channel list: >>> tune to: 609000000:INVERSION_AUTO:5217000:FEC_3_4:QAM_256 >>> tuning status == 0x00 >>> tuning status == 0x07 >>> tuning status == 0x1f 0x0093 0x0026: pmt_pid 0x0758 (null) -- SporTV2 (running, scrambled) 0x0093 0x0027: pmt_pid 0x0748 (null) -- SporTV (running, scrambled) 0x0093 0x0036: pmt_pid 0x0768 (null) -- FX (running, scrambled) 0x0093 0x0052: pmt_pid 0x0788 (null) -- The History Channel (running, scrambled) Signed-off-by: -

Now, it outputs: [10927.639641] drxk: SCU_RESULT_INVPAR while sending cmd 0x0203 with params: [10927.646283] drxk: 02 00 00 00 10 00 07 00 03 02 .......... Better than ERROR -3. This happens with Terratec H5 firmware. It adds 2 new error conditions, and something useful to track what the heck is that. I suspect that the scu_command is dependent on the firmware revision.

The driver is too limited: it assumes that UIO is used only for controlling the antenna, and that only UIO-1 is in usage. However, from Terratec H7 driver [1], 3 UIO's can be used. In fact, it seems that H7 needs to use all 3. So, make the code generic enough to handle the most complex scenario. For now, only antena GPIO can be specified, but is is easier now to add the other GPIO/UIO needs. Signed-off-by: -

This driver is very big and complex. An error happening in the middle of any initialization may cause the frontend to not work. So, it needs to properly propagate error codes internally and to userspace. Also, printing the error codes at the places it happened helps to discover were's a bug at the code. Before this change, a do { } while (0) loop and lots of breaks inside were used to propagate errors. While this works, if there are loops inside other loops, it could be easy to forget to add another break, causing the error to not abort the function. Also, as not all functions were reporting errors, it is hard to discover why something failed. Signed-off-by:
