* V4L/DVB (9724): cx18: Streamline cx18-io[ch] wrappers and enforce MMIO retry ↵Andy Walls2008-12-301-2/+0
| | | | | | | | | | | | | strategy cx18: Streamline cx18-io[ch] wrappers and enforce MMIO retry strategy so that write retries always occur and read retries never occur (as they never help). Remove MMIO statistics logging to speed up MMIO accesses. Deprecate & ignore retry_mmio and mmio_ndelay module parameters, to essentially force retry_mmio=1 and mmio_ndelay=0.

* V4L/DVB (9512): cx18: Fix write retries for registers that always change - ↵Andy Walls2008-12-291-9/+15
| | | | | | | | | | | | | | part 3. cx18: Fix write retries for registers that always change - part 3. Fix the io for the rest of the registers that will often not read back the value just written. Modified register readback checks to make sure the intended effect was achieved without constantly rewriting the registers. The one outstanding register remaining is 0xc72014 CX18_AUDIO_ENABLE, whose behavior on writes I have yet to determine.

This is a first step in instrumenting all CX23418 PCI bus IO, to debug problems with accessing the CX23418's PCI memory mapped IO.

| | | | | | | | | | | | HVR-1600 for lirc cx18: added in cx18_ir_reset_gpio function for lirc_pvr150 like module. Also added the ability to reset the IR chip via ioctl like ivtv. This needs the mutex to protect gpio_dir and gpio_val in struct cx18 as gpio changes can come from a few different asynchronous sources now.

* V4L/DVB (8068): cx18: Add I2C slave reset via GPIO upon initializationAndy Walls2008-06-261-1/+25
| | | | | | | | | | | cx18: Add I2C slave reset via GPIO upon initialization. One user, Michael <msd4824@yahoo.com>, has reported this allows his HVR-1600 EEPROM to be consistently recognized when using (long,) 100 msec delays. The delays in this commit are nominal (10 & 40 msec) and need testing/tuning on boards with I2C problems to find the right values.

Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from Conexant for their support. I am in particular thankful to Hauppauge since without their help this driver would not exist. It should also be noted that Steve did the work to get the DVB part up and running. Thank you!
