@Secam7 I found Your post.
I took original dtb You uploaded and converted it to CE version. You could try to add this to Your dts:
/{
/delete-node/ demux;
dvb {
compatible = "amlogic,dvb";
dev_name = "avl6762";
ts1 = "parallel";
ts1_control = <0x0>;
ts1_invert = <0x0>;
dtv_demod0_i2c_adap_id = <3>;
fec_reset_gpio-gpios = <&gpio_ao GPIOAO_10 GPIO_ACTIVE_HIGH>;
/*ant_power_gpio-gpios = <&gpio_ao GPIOE_2 GPIO_ACTIVE_LOW>;*/ //not used by the driver
/*tuner_power_gpio-gpios = <&gpio GPIOH_8 GPIO_ACTIVE_LOW>;*/ //not used by the driver
pinctrl-names = "p_ts1";
pinctrl-0 = <&dvb_p_ts1_pins>;
clocks = <&clkc CLKID_DEMUX
&clkc CLKID_ASYNC_FIFO
&clkc CLKID_AHB_ARB0
&clkc CLKID_HIU_IFACE>;
clock-names = "demux", "asyncfifo", "ahbarb0", "uparsertop";
interrupts = <GIC_SPI 23 IRQ_TYPE_EDGE_RISING>,
<GIC_SPI 5 IRQ_TYPE_EDGE_RISING>,
<GIC_SPI 19 IRQ_TYPE_EDGE_RISING>,
<GIC_SPI 25 IRQ_TYPE_EDGE_RISING>;
interrupt-names = "demux0", "demux1", "asyncfifo0", "asyncfifo1";
};
};
&pinctrl_periphs {
dvb_p_ts1_pins: dvb_p_ts1_pins {
tsin_b {
groups = "tsin_b_sop_z",
"tsin_b_valid_z",
"tsin_b_clk_z",
"tsin_b_din0_z",
"tsin_b_din1",
"tsin_b_din2",
"tsin_b_din3",
"tsin_b_din4",
"tsin_b_din5",
"tsin_b_din6",
"tsin_b_din7";
function = "tsin_b";
};
};
};
&i2c3 {
status = "okay";
clock-frequency = <400000>;
};
There are still two gpio that are in original dtb and are not covered by the CE driver (those commented ones). ant_power is only to enable 5V on the antenna output for the antenna amplifier, if You have external power source for the antenna then You can forget it. The other one tuner_power may be required, but lets try without it first.
Of course try with Amlogic-ng kernel and install dvb-latest drivers from the CE addon repo.
