device tree syntax error

[kangmw086]

I use the imx6q Sabreauto board.

- yocto

- kernel version : 4.9.11-r0

arch/arm/boot/dts/imx6q-pinfunc.h  is defined as follows.

#define MX6QDL_PAD_EIM_A16__EIM_ADDR16              0x0f4 0x408 0x000 0x0 0x0
#define MX6QDL_PAD_EIM_A16__IPU1_DI1_DISP_CLK       0x0f4 0x408 0x000 0x1 0x0

ps. There is no error in this code.

It does not seem to read the values defined in the imx6q-pinfunc.h  file.

It is in an  imx6q-pinfunc.h file but will define and use MX6QDL_PAD_CSI0_DAT4__IPU1_CSI0_DATA04 .

arch/arm/boot/dts/imx6qdl-sabreauto.dtsi 

add code...

+ #define MX6QDL_PAD_EIM_A16__IPU2_CSI1_PIXCLK        0x0f4 0x408 0x8e0 0x2 0x1

Does this cause problems?

Best regards!

Hi k

there are several dts files for using some peripherals, so one can select appropriate,

for example imx6dl-sabreauto-flexcan1.dts or for eim usage one can use appropriate eim dts file:

linux/arch/arm/boot/dts/imx6dl-sabreauto-gpmi-weim.dts

imx6dl-sabreauto-gpmi-weim.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel
