About using CSI and PWM functions at the same time

[JanTang]

Hello everyone, I wanted to enable PWM8_OUT on imx6ull's ENET1_RX_ER port, but I noticed that pwm8 also manages the pwm output on the CSI_HSYNC port. Does this mean that there is some kind of potential conflict (e.g. CCM configuration) if I want to enable CMOS Sensor Interface (CSI) at the same time? What do I need to pay attention to? Thanks a lot.

refer to the dts file

"https://github.com/nxp-imx/linux-imx/blob/git.kernel.org/linux-stable/linux-4.14.y/arch/arm/boot/dts..."

MX6UL_PAD_CSI_HSYNC__CSI_HSYNC 0x1b088

so PWM8 doesn't be used for csi hsync in current bsp, you can use it
