The lcd driver rk3288_lcdc.c can't compile in kernel 4.4

[txyugood]

Hi everyone, I want to enable the rk3288 lcdc driver in kernel 4.4. When I compiled the kernel, there were some errors. The compiler can't find these files: #include <linux/rockchip/cpu.h> #include <linux/rockchip/iomap.h> #include <linux/rockchip/common.h> Then I go to the kernel/include/linux/rockchip/, these header files are missing! How can I solve this problem?

https://github.com/rockchip-linux/kernel/issues/137 Has more discussion.. I'm trying to get this to compile with rk3188 lcdc driver with similar missing files. I believe the files should be from hw manufacturer. Since my old kernel is 3.0.72, there isn't a straight way to get around this. I'm going to try https://github.com/ayufan-rock64/linux-kernel/releases/tag/4.4.138-1100-rockchip-ayufan
