use device tree for RPi 7" touchscreen/MCU

[Tonymac32]

Instead of sticking it in rockchip.c

I've already done this on Armbian Legacy kernel, leaving the drivers unchanged, leaving the I2C entries out of rockchip.c.
added to rk3288-miniarm.dts:

&i2c3 {
status = "okay";

tinker_ft5406:tinker_ft5406@38 {
    compatible = "tinker_ft5406";
    reg = <0x38>;
};

tinker_mcu:tinker_mcu@45 {
    compatible = "tinker_mcu";
    reg = <0x45>;
};

};

Also, the tinker_mcu and asus_mcu are redundant but different (unless there is some special hardware floating around?) I'm using the tinker_mcu driver successfully, omitted the asus_mcu files entirely. Just thought one less bit of Tinker-specific kernel code to keep track of might be nice.

Hi, Tony
We think your comment is good. Can you give us the patch or we can modify this by ourselves ?

Hello James,

#5

This is, I believe complete, as always test.

Another bit I had to do to keep the Tinker board and other RK3288 boards on a common kernel is to check the board DT compatible on the reboot workarounds.

Hi, Tony
Thanks for the reminder, we will follow the armbian commit to add the DT compatible check.
