2008-06-14Improve error message at tda1004x_attachMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> When an error occurs at firmware loading, sometimes, tda1004x stops answering. Instead of reporting such error, attach code were assuming that the device were answering an invalid ID (0xff). This can be seen when enabling debug options: tda1004x: tda1004x_read_byte: reg=0x0 tda1004x: tda1004x_read_byte: error reg=0x0, ret=-5 Now, instead of reporting an invalid ID, it will report the correct error: tda10046: chip is not answering. Giving up. saa7133[0]/dvb: failed to attach tda10046 saa7133[0]/dvb: frontend initialization failed A possible improvement would be trying to reset the device.

2008-06-14Improve error messages for tda1004x attachMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> A fresh copy of v.29 firmware, using get_firmware, is leading to an invalid firmware: DVB: registering new adapter (saa7133[0]) DVB: registering frontend 0 (Philips TDA10046H DVB-T)... tda1004x: setting up plls for 48MHz sampling clock tda1004x: found firmware revision ff -- invalid tda1004x: trying to boot from eeprom tda1004x: found firmware revision ff -- invalid tda1004x: waiting for firmware upload... tda1004x: Error during firmware upload tda1004x: found firmware revision ff -- invalid tda1004x: firmware upload failed Sometimes, loading/unloading this firmware makes tda1004x to return an invalid ID. However, there were no printk messages to help to identify what were the cause for the error. With this patch, it will now print: Invalid tda1004x ID = 0xff.

From: Hartmut Hackmann <hartmut.hackmann@t-online.de> The struct tda1004x_config has a new entry: .ts_mode Possible values are TDA10046_TS_PARALLEL or TDA10046_TS_SERIAL There always is only one interface active, default is parallel.

From: Hartmut Hackmann <hartmut.hackmann@t-online.de> - The i2c data buffer in tda827xa_set_params was 1 byte too short - saa7134-dvb now gives an error mesage if tda827x could not be attached - coding style fix in tda1004x.c Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de>
2007-02-04set tda827x to sleep mode after attachHartmut Hackmann
From: Hartmut Hackmann <hartmut.hackmann@t-online.de> This change sets the tda827x to sleep mode right after attach in dvb mode. It is just to save power. For the same reason, the ADC of the tda10046 gets turned off in sleep mode. Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de>
2007-01-25tda1004x: check request firmware for NULL ponter againHartmut Hackmann
From: Hartmut Hackmann <hartmut.hackmann@t-online.de> In older versions, this was used to decide whether to boot from eeprom or file. This is no longer necessary but the check helps to avoid an oops with misconfigured cards. Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de>
2007-01-22tda1004x driver updatesHartmut Hackmann
From: Hartmut Hackmann <hartmut.hackmann@t-online.de> There are the following changes: - separate configuration of IF and GPIOs. - set GPIOs before firmware load. This helps to avoid I2C address collisions. - if desired invert GPIOs at sleep (automatic return to analog mode of card). - added 3 tuner configuration bytes to config stuct. - added i2c gate address to config struct. - moved _state struct declaration to header file to make it accessible on board layer. - added "conf_probed" to the state struct to allow i.e. probing for correct tuner version. - changed firmware load mechanism to always: + check if already loaded + try to boot from eeprom + try downlad from host - corrected name of tda10046 firmware image (backward compatible).

2006-05-14Change dvb_frontend_ops to be a real field instead of a pointer field inside ↵Patrick Boettcher
dvb_frontend From: Patrick Boettcher <pb@linuxtv.org> The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver is having a field of dvb_frontend_ops in its private-state-struct and using the reference for filling the pointer-field in dvb_frontend. - It saves at least two lines of code per demod-driver, - reduces object size (one less dereference per frontend_ops-access), - be coherent with dvb_tuner_ops, - makes it a little bit easier for newbies to understand how it works and - avoids stupid mistakes because you would have to copy the dvb_frontend_ops always, before you could assign the static pointer directly, which was dangerous.

2006-03-30Fix budget-av CAM resetAndrew de Quincey
From: Andrew de Quincey <adq_dvb@lidskialf.net> Unfortunately on the budget-av board, the CAM reset line is tied to the frontend reset line, so resetting the CAM also zaps the frontend. This breaks the tda1004x at least, and causes it to fail to tune until the budget-av module is reloaded. This patch adds an exported function to dvb_frontend that allows a card to forcibly reinitialise a frontend. The budget-av now does this on CAM reset, which corrects this problem. Note: other CA interface implementations (e.g. budget-ci) do not need this since they do not tie the CAM reset line to the frontend reset line.

2005-11-07[PATCH] fix missing includesMichael Krufky
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.
