1.刷新率=dotclock/(horizontal period)*(vertical period)
2.horizontal period = left margin + right margin + hsync + xres
3.vertical period = upper margin + low margin + vsync + yres
4.h_bp 左边界 h_fp 右边界 v_bp 上边界 v_fp 下边界 h_pw 水平同步 v_pw 垂直同步
5.bp:back porch; fp:front porch; pw:pulse width;
6.Pixclock = 1 / dotclock
7.hdmi_init_lcdc(rk29fb_screen, rk29lcd_info *lcd_info) >> .set_screen__info >> rk3188_lcdc_probe call set_screen_info
