NVIDIA TX1 Audio CODEC

Hi
I want to add Audio CODEC on TX1 and plan to use ALC5639 as TK1 Dev-board.
Does TX1 has ALC5693 driver as TK1, how much effort need to porting TK1 driver to TX1? thank you.

Hello,
You can refer to rt5639 code @ sound/soc/codecs/.

with deep understanding of codec chip and codec driver infrastructure, it should not be very difficult to port such driver.

Hi Jachen
thank you for your reply

Hi Jachen
I saw there is tegra_rt5639.c file in folder kernel\sound\soc\tegra, is this is the ALC5639 driver for TX1?

Hello, bangbang_meg:
you are right.

Hi Jachen

I can’t open soc\tegra ALC5639 FLAG on TX1
I use R24.2.1 kernel firmware , if i use menuconfig to open this flag the firmware will build error.

could you provide the SOP to build ALC5639 driver on TX1.

Hello, etta:
RT5639 has already be enabled in kernel:
CONFIG_SND_SOC_RT5639=y

Hi Jachen

Thanks your help.
So R24.2.1 kernel firmware has already be enabled ALC5639 driver.

And if i change to ALC5640 how did i modify the flag?
Could you provide some suggestion?

Hello, etta:
I’m not sure about 5640.
You can either create a new driver for 5640, and add corresponding driver/DTS, or just make some change based on 5639.

You can refer to ‘Tegra ASoC Driver’ @ ‘L4T R24.2.1 Documentation’ (downloaded from https://developer.nvidia.com/embedded/downloads)

Hi Jachen

thanks your information.

But i have a question about ALC5639.
you say the kernel firmware has already be enabled ALC5639 driver.

why the driver enable the tegra-snd-t210ref-mobile-rt565x module?
did i need to modify something to change to ALC5639 driver?

Hello, etta:
Sorry for my mistake.
RTL5639 is for TK1 board.

In TX1, you should refer to RT565x.
