标题: FirePrime不能点亮MiPi接口的屏，求协助，谢谢！
1、修改了rk3128-fireprime.dts，屏蔽了HDMI，打开了lcdc
   &lcdc {
   status = "okay";
rockchip,mirror = <NO_MIRROR>;
rockchip,cabc_mode = <0>;
power_ctr: power_ctr {
  rockchip,debug = <1>;
  /*lcd_en:lcd_en {
rockchip,power_type = <GPIO>;
gpios = <&gpio7 GPIO_A3 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
  };
  lcd_cs:lcd_cs {
rockchip,power_type = <GPIO>;
gpios = <&gpio7 GPIO_A4 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
  };*/
lcd_rst:lcd_rst {
rockchip,power_type = <GPIO>;
gpios = <&gpio1 GPIO_A7 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
};
  };
};
2、在fireprime_defconfig增加了
   CONFIG_LCD_MIPI=y
CONFIG_MIPI_DSI=y
CONFIG_RK32_MIPI_DSI=y

3、增加了自己的mipi dtsi文件
4、错误如下：

[ 0.883620] delay:10[ 0.883620] atv_val:1[ 0.883620] gpio:39[ 0.883620] pwr_type:gpio[ 0.883620] pwr_ctr_name:lcd_rst[ 0.883591] rk312x-lcdc lcdc0: request lcd_rst gpio fail:-16[ 0.882572] rk32-mipi 10110000.mipi: rockchip mipi_dsi v1.1 2014-06-17rk32-mipi 10110000.mipi: rk mipi_dsi probe success!
rk312x-lcdc lcdc0: set lcdc0 dclk failed

请问是什么原因？
