一、.XML Configure
1.一些主要的配置
<Version>"1.0"</Version>
<PanelId>st7703-720p-video</PanelId>
<PanelH>st7703_720p_video</PanelH>
0x29, 0x01, 0x00, 0x00, 0x00 = REGISTER
PayloadSize = Number+1
Payload = CMD,DATA,DATA,…
size CMD DATA
<OnCommand> | | |
0x29, 0x01, 0x00, 0x00, 0x00, 0x02, 0xFF, 0xEE,</OnCommand>
根据Excel2016工具计算
<!-- Panel Timing -->
<PanelTimings>"0x76, 0x18, 0x10, 0x00, 0x3A, 0x3E, 0x14, 0x1C, 0x12, 0x03, 0x04, 0x00"</PanelTimings>
2.生成设备树文件和头文件
#perl parser.pl .xml panel
3.把文件移到相应的位置
kernel/msm-4.9/arch/arm64/boot/dts/qcom/XXXX.dtsi
bootable/bootloader/lk/dev/gcdb/display/include/XXXX.h
二、Configure Kernel
1.Include .dtsi files.
kernel/msm-4.9/arch/arm64/boot/dts/qcom/msm8953-mdss-panels.dtsi
+#include "dsi-panel-st7703-720p-video.dtsi"
......
+&dsi_st7703_720p_video {
+ qcom,mdss-dsi-panel-timings-phy-v2 = [
+ 1e 1a 04 05 02 03 04 a0 /*Data 0*/
+ 1e 1a 04 05 02 03 04 a0 /*Data 1*/
+ 1e 1a 04 05 02 03 04 a0 /*Data 2*/
+ 1e 1a 04 05 02 03 04 a0 /*Data 3*/
+ 1e 0d 03 05 02 03 04 a0]; /*CLK lane*/
+};
kernel/msm-4.9/arch/arm64/boot/dts/qcom/msm8953-pmi632-panel-camera.dtsi
&mdss_dsi0 {
qcom,dsi-pref-prim-pan = <&dsi_st7703_720p_video>;
pinctrl-names = "mdss_default", "mdss_sleep";
pinctrl-0 = <&mdss_dsi_active &mdss_te_active>;
pinctrl-1 = <&mdss_dsi_suspend &mdss_te_suspend>;
qcom,platform-te-gpio = <&tlmm 24 0>;
qcom,platform-reset-gpio = <&tlmm 61 0>;
qcom,platform-bklight-en-gpio = <&pm8953_gpios 4 0>;
//qcom,platform-enable-gpio = <&pmi632_gpios 6 0>;
};
2.Configure the Backlight
kernel/msm-4.9/arch/arm64/boot/dts/qcom/msm8953-pmi632-panel-camera.dtsi
&dsi_st7703_720p_video {
qcom,panel-supply-entries = <&dsi_panel_pwr_supply>;
qcom,mdss-dsi-bl-pmic-control-type = "bl_ctrl_pwm";
qcom,mdss-dsi-bl-pmic-pwm-frequency = <100>;
qcom,mdss-dsi-bl-pmic-bank-select = <0>;
qcom,mdss-dsi-bl-pwm-pmi;
pwms = <&pmi632_pwm 3 1000000>;
qcom,mdss-dsi-pwm-gpio = <&pmi632_gpios 6 0>;
pinctrl-names = "default";
pinctrl-0 = <&pwm_out_default>;
//qcom,mdss-dsi-pwm-gpio = <&pm8953_mpps 4 0>;
};
If PWM backlight control is used on DSI0, please disable the DSI1 bridge.
&soc {
//rid:add dsi1 bridge for dual mipi dsi
qcom,dsi1_bridge {
- compatible = "qcom,dsi1_bridge";
+ //compatible = "qcom,dsi1_bridge";
instance_id = <0>;
mdss-dsi-bl-pmic-pwm-frequency = <100>;
mdss-dsi-bl-pmic-bank-select = <0>;
三、Configure LK
1Add several parameters to panel_hx8394f_720p_video.h to avoid compiling error
/*---------------------------------------------------------------------------*/
/* Panel configuration */
/*---------------------------------------------------------------------------*/
static struct panel_config st7703_720p_video_panel_data = {
"qcom,mdss_dsi_st7703_720p_video", "dsi:0:", "qcom,mdss-dsi-panel",

};
/*---------------------------------------------------------------------------*/
/* Lane configuration */
/*---------------------------------------------------------------------------*/
static struct lane_configuration st7703_720p_video_lane_config = {
4, 0, 1, 1, 1, 1, 0
};
2.Add the DSI PHY 2.0.0 timing config mentioned in
panel_hx8394f_720p_video.h.
static const uint32_t st7703_720p_video_timings[] = {
0x76, 0x18, 0x10, 0x00, 0x3A, 0x3E, 0x14, 0x1C, 0x12, 0x03, 0x04, 0x00

};
static struct panel_timing st7703_720p_video_timing_info = {
0, 4, 0x04, 0x19
};
3 Add a new panel.
