d1 lvds dual

[sogen]

d1 lvds dual，SDK文档里说支持，dts里没有相关定义SDK里也没有相关代码，有没有人知道怎么在d驱动dlvds dual link大屏

@sogen 首先在dts中配置lvds1的gpio，大致是下面这样的

			lvds1_pins_a: lvds1@0 {
				pins  = "PD10", "PD11", "PD12", "PD13", "PD14", "PD15", "PD16", "PD17", "PD18", "PD19";
				function = "lvds1";
				drive-strength = <30>;
				bias-disable;
			};

			lvds1_pins_b: lvds1@1 {
				pins  = "PD10", "PD11", "PD12", "PD13", "PD14", "PD15", "PD16", "PD17", "PD18", "PD19";
				function = "io_disabled";
				drive-strength = <30>;
				bias-disable;
			};

然后在dts中配置dual lvds，主要是lcd_lvds_if与pinctrl-0

&lcd0 {
	lcd_used            = <1>;

	lcd_driver_name     = "default_lcd";
	lcd_backlight       = <50>;
	lcd_if              = <3>;

	lcd_x               = <640>;
	lcd_y               = <2560>;
	lcd_width           = <150>;
	lcd_height          = <94>;
	lcd_dclk_freq       = <117>;

	lcd_pwm_used        = <0>;
	lcd_pwm_ch          = <7>;
	lcd_pwm_freq        = <50000>;
	lcd_pwm_pol         = <1>;
	lcd_pwm_max_limit   = <255>;
 
	lcd_hbp             = <40>;
	lcd_ht              = <720>;
	lcd_hspw            = <20>;
	lcd_vbp             = <20>;
	lcd_vt              = <2600>;
	lcd_vspw            = <10>;
	
	lcd_lvds_if         = <1>;
	lcd_lvds_colordepth = <0>;	
	lcd_lvds_mode       = <0>;
	lcd_frm             = <0>;
	lcd_hv_clk_phase    = <0>;
	lcd_hv_sync_polarity= <0>;
	lcd_gamma_en        = <0>;
	lcd_bright_curve_en = <0>;
	lcd_cmap_en         = <0>;

	deu_mode            = <0>;
	lcdgamma4iep        = <22>;
	smart_color         = <90>;
	
        pinctrl-0 = <&lvds0_pins_a &lvds1_pins_a>;
        pinctrl-1 = <&lvds0_pins_b &lvds1_pins_b>;	
  
};
