第一次用F133，驱动I80接口失败，求助大佬

zhangjingxun12 LV 4

这是第一次弄全志soc和linux，一路跟着tina的文档走，前面调试rgb屏测试ok，不过后面想用i80接口，结果这几天折腾，没折腾明白，网上没找到对应的（有其他的，但没看明白，实力限制……），发个帖求助下大佬们，因为初次搞这个，操作步骤粗鄙不堪入目之处，请多多见谅，后面可以多给小弟批评指正下，多谢！

先说问题

进入系统后，启动日志：

lcd初始化部分，设备树设置的320*240，不知道这里fb的800哪里来的

然后查看disp的sys信息

root@TinaLinux:/# cat /sys/class/disp/disp/attr/sys

可以看到mgr0是0x0，后面frame又是800x480，有问题，但不知出在哪儿……前面rgb屏frame也是这样，不过我用测试代码修改了fb_var_screeninfo才行
切换到dispdbg，用suspend命令

root@TinaLinux:/# cd /sys/kernel/debug/dispdbg/
root@TinaLinux:/sys/kernel/debug/dispdbg# echo disp0 > name
root@TinaLinux:/sys/kernel/debug/dispdbg# echo suspend >command
root@TinaLinux:/sys/kernel/debug/dispdbg# echo 1 >start

[ 1170.870085] disp_suspend finish
root@TinaLinux:/sys/kernel/debug/dispdbg#

lcd_panel_fun0.cfg_close_flow is NULL这个搞的有点蒙，在lcdpanel里，这里cfg_close_flow是有的，不知道这里为啥是个NULL，另外lcd_panel_fun0这里括号，是我在源码
lichee/linux-5.4/drivers/video/fbdev/sunxi/disp2/disp/de/disp_lcd.c----->disp_lcd_disable中改的

DE_WRN("lcd_panel_fun[%d](%s--%s).cfg_close_flow is NULL\n", lcd->disp,lcdp->panel_info.lcd_model_name,lcdp->panel_info.lcd_driver_name);

但似乎，都是空值，所以是不是驱动挂的不是指定的panel呢？

下面是我添加驱动到配置的具体步骤，新手操作，粗鄙难入眼之处，请多担待……

再说步骤

根据手头的Tina的开发文档，及自己的理解，我分为以下几个步骤：

在lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd/路径添加ili9341_80.c和ili9341_80.h
如下，c文件

2.在kconfig添加驱动项
文件lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd/Kconfig，增加

config LCD_SUPPORT_ILI9341_80_PANEL
	bool "LCD support ili9341 i80 panel"
	default y
	---help---
		If you want to support led panel for display driver, select it.This panel used for ili9341 i80 mode.

makfile添加编译
文件lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/Makefile，在屏幕编译部分添加

disp-$(CONFIG_LCD_SUPPORT_HE0801A068) += lcd/he0801a068.o
...
disp-$(CONFIG_LCD_SUPPORT_K101_MM2QA01_A) += lcd/K101_MM2QA01_A.o
disp-$(CONFIG_LCD_SUPPORT_ILI9341_80_PANEL) += lcd/ili9341_80.o

将上面的panel添加到panels
文件lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd/panels.h
在后面最后一行#endif前添加

#ifdef CONFIG_LCD_SUPPORT_ILI9341_80_PANEL
extern __lcd_panel_t ili9341_80_panel; 
#endif

文件lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd/panels.c
panel_array结构体最后的null前面添加

#ifdef CONFIG_LCD_SUPPORT_ILI9341_80_PANEL
	&ili9341_80_panel,
#endif

修改设备树
在lichee/linux-5.4/arch/riscv/boot/dts/sunxi/sun20iw1p1.dtsi添加I80的引脚分配

pio: pinctrl@2000000 {
	...
	I8080_16bit_pins_a: I8080_16bit@0 {
		pins = "PD0", "PD1", "PD2", "PD3", "PD4", "PD5", \

		function = "lcd0";
		drive-strength = <30>;
		bias-disable;

		function = "io_disabled";
		bias-disable;
	};
}

在device/config/chips/f133/configs/mq_r/linux-5.4/board.dts
添加lcd0的配置，将其他lcd0屏蔽
根据Tina_lcd的文档，lcd_cpu_if取值

0： 18bit/1cycle (RGB666)
2: 16bit/3cycle (RGB666)
4： 16bit/2cycle (RGB666)
