D1S/F33 LCD驱动问题

[bgv1122]

mango开发板，跑mango官网首页固件能正常显示，但这个固件没有cma，因此打算自己从全志官网的SDK编译，但irq一直无中断，请问这是什么情况：
root@TinaLinux:/# cat /sys/class/disp/disp/attr/sys

这是lcd0的配置：
&lcd0 {
compatible = "allwinner,sunxi-lcd0";
status = "okay";
lcd_used = <1>;
lcd_driver_name = "default_lcd";

lcd_backlight = <50>;
lcd_if = <0>;

lcd_x = <800>;
lcd_y = <480>;
lcd_width = <150>;
lcd_height = <94>;
lcd_dclk_freq = <48>;

lcd_pwm_used = <0>;
lcd_pwm_ch = <7>;
lcd_pwm_freq = <500>;
lcd_pwm_pol = <0>;
lcd_bl_en = <&pio PD 22 1 0 3 1>; /* 设为纯 GPIO 输出高电平 */

lcd_hbp = <55>;
lcd_ht  = <1240>;
lcd_hspw = <20>;

lcd_vbp = <35>;
lcd_vt  = <650>;
lcd_vspw = <10>;

lcd_lvds_if = <0>;
lcd_lvds_colordepth = <1>;
lcd_lvds_mode = <0>;

lcd_frm = <0>;
lcd_io_phase = <0>;

lcd_gamma_en = <0>;
lcd_bright_curve_en = <0>;
lcd_cmap_en = <0>;
deu_mode = <0>;
lcdgamma4iep = <22>;
smart_color = <90>;

pinctrl-0 = <&rgb18_pins_a>;
pinctrl-1 = <&rgb18_pins_b>;

};
