| #################### |
| |
| The Digital TV device configure by dts in arch/arm/boot/dts/amlogic/ |
| or arch/arm64/boot/dts/amlogic/, it can configure the dmx/ca/dvr/net |
| device num. at same time configure the external demod according to |
| different hardware platform |
| for example: |
| |
| .. code-block:: c |
| |
| demux { |
| compatible = "amlogic sc2, dvb-demux"; |
| dev_name = "dvb-demux"; |
| status = "okay"; |
| |
| reg = <0x0 0xfe000000 0x0 0x480000>; |
| // using dmxdev num, max num is 32 |
| dmxdev_num = <4>; |
| |
| /*single demod setting */ |
| /*ts will bind with dmx device*/ |
| ts0_dmx = <0>; |
| ts1_dmx = <1>; |
| |
| /*set pass tse or not, default is 1*/ |
| tse_enable = <0>; |
| |
| /*multi demod setting, such as maxlinear demod*/ |
| /*attention: ts how to bind to dmx device |
| it should set sid in maxlinear driver |
| sid list: |
| dmx0 sid:0x20 |
| dmx1 sid:0x21 |
| ... |
| dmx31 sid:0x2F |
| */ |
| ts2_header_len = <4>; |
| ts2_header = <0x4b>; |
| ts2_sid_offset = <1>; |
| ts2 = "serial-4wire"; |
| ts2_control = <0x0>; |
| |
| pinctrl-names = "s3_ts0"; |
| pinctrl-0 = <&dvb_s_ts0_pins>; |
| }; |
| |
| .. note:: |
| |
| - dmxdev_num: default value is 32. and sid should be from 32 to 63. it should be set according to the hardware. |
| |
| - fex_xxx: it define the demod hardware configure. |
| |
| - pinctrl-xxx: it define the demod's pinmux. |
| |
| - tsx_xxx: it define the ts configure with fex. |
