IMX8MQ IPU

Hi,NXP

I'm using imx8mq, and I wanted to use mipi-dsi to HDMI for display, but found that the mipi-dsi module could not be used during kernel setup because MXC_IPU must be available at ARCH_MXC instead of ARCH_MXC_ARM64.How do I use the mipi-dsi module of imx8mq?

and this is Kconfig of MXC

# drivers/mxc/Kconfig

if ARCH_MXC || ARCH_MXC_ARM64

menu "MXC support drivers"

# drivers common to MXC and MX8 go here:
source "drivers/mxc/gpu-viv/Kconfig"
source "drivers/mxc/hantro/Kconfig"
source "drivers/mxc/mlb/Kconfig"
source "drivers/mxc/hdp/Kconfig"
source "drivers/mxc/hdp-cec/Kconfig"

config MXC_SIM
tristate "MXC SIM support"
default n
---help---
Say Y to get MXC SIM support.

source "drivers/mxc/sim/Kconfig"

if ARCH_MXC_ARM64
source "drivers/mxc/hantro_845/Kconfig"
source "drivers/mxc/hantro_845_h1/Kconfig"
source "drivers/mxc/vpu-malone/Kconfig"
source "drivers/mxc/vpu-decoder-b0/Kconfig"
source "drivers/mxc/vpu-encoder-b0/Kconfig"
endif

if ARCH_MXC
config MXC_IPU
bool "Image Processing Unit Driver"
select MXC_IPU_V3
help
If you plan to use the Image Processing unit, say
Y here. IPU is needed by Framebuffer and V4L2 drivers.

source "drivers/mxc/ipu3/Kconfig"
source "drivers/mxc/mipi/Kconfig"
source "drivers/mxc/vpu/Kconfig"
source "drivers/mxc/hdmi-cec/Kconfig"
endif

source "drivers/mxc/vehicle_rpmsg/Kconfig"

endmenu

endif

Hi dhty2015

for mipi-dsi to HDMI one can look at

Design Files for the MIPI to HDMI Converter (IMX-MIPI-HDMI)

Hi igorpadykov

Another problem, I now use imx8mq to add sound card device, using i2s interface, but the official demo only USES SAI interface, and there is no configuration of i2s in DTS.What do I need to do to use i2s as the sound output?
