三个月之前有调试过一块MIPI接口的小屏幕，最近又买了一款新的MIPI接口的屏幕，本以为会像上次一样顺顺利利的，结果....

废话不多说，这次买的屏幕长这样：

基本参数：

是2通道的MIPI接口，驱动IC是ST7701s，2寸，分辨率480*360。

管脚：

转接板：

数据手册：
ST7701S_SPEC_+V1.1.pdf

初始化代码：

/*
VFP=VBP=6=VS=6
HFP=HBP=6=HS=220
pll_clock=155;
*/

现在有个疑问是下面的这几个参数，手册中只给了几个范围:

然后卖家给的初始化代码开头的几行注释，跟代码中实际设置的貌似也不一致....
卖家给的：

VFP=VBP=6=VS=6
HFP=HBP=6=HS=220
pll_clock=155;

初始化代码计算的：

{0xFF, 5, {0x77, 0x01, 0x00, 0x00, 0x10}},
{0xC0, 2, {0x2C, 0x00}},  // SCNL = (0x2c + 1) * 8 = 360
{0xC1, 2, {0x08, 0x02}},  // VFB=0x08  VBF=0x02
{0xC2, 2, {0x37, 0x05}},  // PCLK= 512 + (0x05 * 16) = 592

HFP和HBP没看到有相关的命令设置...

现在的主要问题是下面这几个参数，我尝试了用各种方式计算，貌似都不对，

lcd_hbp             = <>;
lcd_ht              = <>;
lcd_hspw            = <>;
lcd_vbp             = <>;
lcd_vt              = <>;
lcd_vspw            = <>;

lcd_dsi_if          = <0>;
lcd_dsi_lane        = <2>;

有大佬帮忙看一下吗 (我这里有两个屏幕和两个转接板，有想调的，可以联系我 )
