Hello, to avoid this error, you can disable strict mode in the pin controller driver https://elixir.bootlin.com/linux/v6.7.12/source/drivers/pinctrl/sunxi/pinctrl-sun50i-h616.c But I'm not sure that the driver for this touchscreen can work on allwinner processors without changes, because their "gpio_in" and "irq" are different multiplexer states I think they cannot work simultaneously, so something similar is needed PS Of course you can use different pins for interrupts and gpio and then everything should work out of the box.

Perhaps it will be interesting to someone - audio on hdmi and edid reading work on the t507 too, there was a problem in our DDC connection scheme.

This device is used to control the Audio HUB сrossbar switch, for example it makes possible to use external i2s interfaces. https://github.com/elkoni/Opi_Zero_3_I2S3_5.4/blob/main/OpiZero3_I2S_3_mixer.JPG

Thanks for confirming. In fact, my patch does not solve the problem and can only be considered as a temporary solution. I think we need a new driver for the audio multiplexer, for example, as is implemented for NXP processors. https://elixir.bootlin.com/linux/v6.6.30/source/sound/soc/fsl/imx-audmux.c For these processors, the audio multiplexer configuration is described via DT https://elixir.bootlin.com/linux/v6.6.30/source/arch/arm/boot/dts/nxp/imx/imx6qdl-kontron-samx6i.dtsi#L176

Hi, I think these messages are not related to analog audio, at least on my custom board with t507 processor, analog audio works with this error. You can simply disable them as it was in the linux kernel 6.1 The sound works for me if I turn it on in the mixer It’s strange, but I have another problem - the sound does not work through HDMI and there is also a problem with reading EDID through the DDC interface. I would be grateful if you could tell me whether automatic detection of monitor or TV resolution via HDMI works for you.
