2015-07-06[media] lmedm04: NEC scancode cleanupDavid Härdeman1-10/+11
This changes the keymap back to the state before commit 616a4b83 and changes the driver to use full NEC32 scancodes following the instructions provided by Malcolm Priestley <tvboxspy@gmail.com>.

2015-06-24[media] lmedm04: fix the range for relative measurementsMauro Carvalho Chehab1-11/+8
Relative measurements are typically between 0 and 0xffff. However, for some tuners (TUNER_S7395 and TUNER_S0194), the range were from 0 to 0xff00, with means that 100% is never archived. Also, TUNER_RS2000 uses a more complex math. So, create a macro that does the conversion using bit operations and use it for all conversions. The code is also easier to read with is a bonus. While here, remove a bogus comment. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-06-24[media] lmedm04: use u32 instead of u64 for relative statsMauro Carvalho Chehab1-3/+3
Cleanup this sparse warning: drivers/media/usb/dvb-usb-v2/lmedm04.c:302 lme2510_update_stats() warn: should '((255 - st->signal_sn - 161) * 3) << 8' be a 64 bit type? Both c_tmp and s_tmp actually stores a u16 stat. Using a u64 data there is a waste, specially on u32 archs, as 64 ints there are more expensive. So, change the types to u32 and do the typecast only when storing the result. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-06-10[media] lmedm04: implement dvb v5 statisticsMalcolm Priestley1-27/+77
Indroduce function lme2510_update_stats to update statistics directly from usb interrupt. Provide signal and snr wrap rounds for dvb v3 functions. Block and post bit are not available. When i2c_talk_onoff is on no statistics are available, with possible future hand over to the relevant frontend/tuner.

2015-06-09[media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab1-5/+5
The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

2015-02-03[media] lmedm04: add read snr, signal strength and ber call backsMalcolm Priestley1-0/+24

2015-02-03[media] lmedm04: Create frontend call back for read statusMalcolm Priestley1-145/+60
Create dm04_read_status to check lock through either interrupt values or directly by the call back. When the device is not streaming the frontends original call back is used. When streaming has started it turns off I2C messaging by setting st->i2c_talk_onoff to zero. I2C can only be turn on again by one of the other allowed frontend calls. All old code is removed from lme2510_msg and this function only needs to set st->i2c_talk_onoff to 1. The lock status is saved and when the frondend is locked is maintained by lme2510_int_response who will now just kill the lock. The call back for rs2000 tuner is nologer required. All frontend types have been tested. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2014-07-24[media] rc-core: document the protocol typeDavid Härdeman1-5/+4
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.

2014-06-17[media] lmedm04: rs2000 check if interrupt urb is over dueMalcolm Priestley1-11/+14
Change handling of signal_lock on rs2000. Use ibuf[2] to detect lock as there is a longer wait for lock to appear in ibuf[6]. Remove last_key and key_timeout and use jiffies plus 60ms to detect that streaming is still active. If the current jiffies is time_after the interrupt urb overdue and clear signal lock. This results in far faster recovery of lock and streaming. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2012-10-27[media] rc-core: add separate defines for protocol bitmaps and numbersDavid Härdeman1-1/+1
The RC_TYPE_* defines are currently used both where a single protocol is expected and where a bitmap of protocols is expected. Functions like rc_keydown() and functions which add/remove entries to the keytable want a single protocol. Future userspace APIs would also benefit from numeric protocols (rather than bitmap ones). Keytables are smaller if they can use a small(ish) integer rather than a bitmap. Other functions or struct members (e.g. allowed_protos, enabled_protocols, etc) accept multiple protocols and need a bitmap. Using different types reduces the risk of programmer error. Using a protocol enum whereever possible also makes for a more future-proof user-space API as we don't need to worry about a sufficient number of bits being available (e.g. in structs used for ioctl() calls). The use of both a number and a corresponding bit is dalso one in e.g. the input subsystem as well (see all the references to set/clear bit when changing keytables for example). This patch separate the different usages in preparation for upcoming patches. Where a single protocol is expected, enum rc_type is used; where one or more protocol(s) are expected, something like u64 is used. The patch has been rewritten so that the format of the sysfs "protocols" file is no longer altered (at the loss of some detail). The file itself should probably be deprecated in the future though.
