Add support for Allwinner (DVB/ATSC) Transport Stream Controller(s) (TSC)

OK, with the patched fex file and devices.c from
[linux-sunxi] [PATCH v2 1/1] [sunxi-boards/a20] Add support for Allwinner (DVB/ATSC) Transport Stream Controller(s) (TSC) [PATCH v2 1/1] [stage/sunxi-3.4] sw_nand: sunxi devices core using wrong MMIO region range, overlaps TSC/TSI register base address 0x01c04000 and the driver patches from this topic here

the driver basically loads and inits:

[  161.016837] [tsc-inf] tscdev_init: kmalloc memory, size: 0x212000
[  161.042378] [tsc-dbg] register_tsiomem: check_mem_region return: 0
[  161.055409] [tsc-dbg] register_tsiomem: devp->regsaddr: 0xf0104000

root@vdr2:~# cat /proc/iomem |grep -C 1 -i ts
01c03000-01c03fff : sw_nand
01c04000-01c04fff : ts regs

root@vdr2:~# ls -l /dev/ts*
crw------- 1 root root 225, 0 Aug 14 19:10 /dev/tsc_dev

And ioctl() triggers the controller setup successfully.

[ 1064.891079] [tsc-inf] tscdev_open: clock rate 192000000

Ready to build the Philips CU1216-MKIII TDA10023 DVB-C- Receiver "recycling" SMT extension board next days. Others are invited to build boards with their receiver modules and extend driver Kconfig for more receivers, too.

Next i2c and frontend driver integration, if someone can do that faster, pls don't wait for me and pls CC linux-media list.

dvb_core integration after the hardware and driver PIO tests success.

Thanks for all the great community support :-)

Hi, I need some help. I am trying to take TS stream input through TS0 Allwinner A20 board by SMDT. I have the Fex file info as below.
[tsc_para]

tsc_used                 = 1
tsc_cla                  = port:PE00<2><default><default><default>
tsc_err                  = port:PE01<2><default><default><default>
tsc_sync                 = port:PE02<2><default><default><default>
tsc_dvld                 = port:PE03<2><default><default><default>
tsc_d0                   = port:PE04<2><default><default><default>
tsc_d1                   = port:PE05<2><default><default><default>
tsc_d2                   = port:PE06<2><default><default><default>
tsc_d3                   = port:PE07<2><default><default><default>
tsc_d4                   = port:PE08<2><default><default><default>
tsc_d5                   = port:PE09<2><default><default><default>
tsc_d6                   = port:PE10<2><default><default><default>
tsc_d7                   = port:PE11<2><default><default><default>

Now, with this I get some error when I load the tscdrv.ko. below are the errors

<6>[  775.488646] [tsc-inf] tscdev_init: kmalloc memory, size: 0x212000

<6>[  775.514991] [tsc-dbg] register_tsiomem: devp->regsaddr: 0xf0012000

am I missing something? Do I need to modify the fex file?

please forgive me if my questions are wrong. I am fairly new to android & Allwinner platform.

thanks a lot

1. The tscdrv.c code (my linux-sunxi port, too) is (c) AW proprietary, You need to contact AW support (+ for a complete TSC Manual).

2. I've suspended my TSC project until a complete A20 TSC manual is available or I get the time for register probe rev. engineering.

3. https://groups.google.com/forum/#!topic/android-porting/EMAG4RUlOjI

"Now we are planning to integrate a TV chip with this (DVB-T) . Allwinner has TS control block and a sample driver along with it."

Who is "we"?

I don't support Android OS platform, nor do "we" support closed source product developers from hidden proprietary products manufacturers usually not releasing derivated works of GPL'd code back to "us" or the android-porting project with their products, especially not for free. Please refer to the known consultant companies if Your company needs "help".

Please, tell Your Boss there's a big difference between "help" and valuable expensive engineering project consulting, thank You. Code maybe free under GPL (only the without warranty version) but consulting for it is not, and violating the GPL is breaking the law, worldwide.

This is the second request directly adressed to me off-list from a commercial company to work for free for them, I will drop any further to the JUNK Mail folder without notice.

thanks A LOT :-//

I am sorry Tom. I was trying to build the AW TSC for SMDT. hope you forgive me for my mistakes.

-thanks

Incomplete. Prove me wrong by getting a full TS without bypassing the TSC using the GPIO ports in other MUX mode directly, if possible (sig speed).

hi
you must have a tsdeviver like dibcom 3000 or anything,so you can done it.
