大佬们,T113的mipi没有clk输出
-
用的是jd9365tx,有init参数,我在设备树设置如下
&disp { disp_init_enable = <1>; disp_mode = <0>; //screen0_output_type = <0>; screen0_output_type = <1>; screen0_output_mode = <4>; screen1_output_type = <1>; screen1_output_mode = <4>; screen1_output_format = <0>; screen1_output_bits = <0>; screen1_output_eotf = <4>; screen1_output_cs = <257>; screen1_output_dvi_hdmi = <2>; screen1_output_range = <2>; screen1_output_scan = <0>; screen1_output_aspect_ratio = <8>; dev0_output_type = <1>; dev0_output_mode = <4>; dev0_screen_id = <0>; dev0_do_hpd = <0>; dev1_output_type = <1>; dev1_output_mode = <4>; dev1_screen_id = <1>; dev1_do_hpd = <1>; def_output_dev = <0>; hdmi_mode_check = <1>; fb0_format = <0>; //fb0_width = <1280>; //fb0_height = <720>; fb0_width = <0>; fb0_height = <0>; fb1_format = <0>; fb1_width = <0>; fb1_height = <0>; chn_cfg_mode = <1>; disp_para_zone = <1>; }; &lcd0 { lcd_used = <1>; lcd_driver_name = "jd9365tx"; lcd_backlight = <100>; lcd_if = <4>; //lcd_x = <1280>; //lcd_y = <720>; //lcd_width = <153>; //lcd_height = <86>; //lcd_dclk_freq = <78>; lcd_x = <720>; lcd_y = <1280>; lcd_width = <86>; lcd_height = <153>; lcd_dclk_freq = <72>; //lcd_dclk_freq = <64>; lcd_pwm_used = <1>; lcd_pwm_ch = <7>; lcd_pwm_freq = <50000>; lcd_pwm_pol = <1>; lcd_pwm_max_limit = <255>; lcd_hbp = <60>; lcd_ht = <800>; //lcd_ht = <1360>; lcd_hspw = <20>; lcd_vbp = <30>; lcd_vt = <1510>; //lcd_vt = <1330>; //lcd_vt = <950>; lcd_vspw = <2>; lcd_dsi_lane = <4>; lcd_dsi_if = <0>; lcd_dsi_format = <0>; lcd_dsi_te = <0>; lcd_frm = <0>; lcd_io_phase = <0>; lcd_gamma_en = <0>; lcd_bright_curve_en = <0>; lcd_cmap_en = <0>; lcdgamma4iep = <22>; smart_color = <90>; lcd_gpio_0 = <&pio PB 7 GPIO_ACTIVE_HIGH>; pinctrl-0 = <&dsi4lane_pins_a>; pinctrl-1 = <&dsi4lane_pins_b>; };屏参数720*1280,原始参数如下

}, };这些函数都调用了,reset也能看到引脚电平在变化,拉低了30ms,但是不管怎样clk脚都没有任何输出,请假大佬们该从哪里入手
我还做了以下的操作:
1,打印查看clk_set_rate返回值为0,设置clk成功
2,查看pinctrl,PD0-PD9都已经是dsi引脚
3,修改clk_tbl为{LCD_IF_DSI, 6, 1, 4, 108000000},确保dclk和dsi_rate正常
恳请大佬们帮忙解决一下!
