drivers/gpu/drm/panel/panel-simple.c
2、屏幕配置
方式一：
把timings写在drivers/gpu/drm/panel/panel-simple.c中, 直接以短字符匹配, 该方式为upstream推荐的使用方式.
Device Tree
panel: panel {
compatible = "cptt,claa101wb01";
ddc-i2c-bus = <&panelddc>;
power-supply = <&vdd_pnl_reg>;
enable-gpios = <&gpio 90 0>;
backlight = <&backlight>;
delay,prepare = <10>;
delay,enable = <10>;
delay,disable = <10>;
delay,unprepare = <10>;
};
drivers/gpu/drm/panel/panel-simple.c:
static const struct drm_display_mode lg_lp097qx1_spa1_mode = {
.clock = 205210,
.hdisplay = 2048,
.hsync_start = 2048 + 150,
.hsync_end = 2048 + 150 + 5,
.htotal = 2048 + 150 + 5 + 5,
.vdisplay = 1536,
.vsync_start = 1536 + 3,
.vsync_end = 1536 + 3 + 1,
.vtotal = 1536 + 3 + 1 + 9,
.vrefresh = 60,
};
static const struct panel_desc lg_lp097qx1_spa1 = {
.modes = &lg_lp097qx1_spa1_mode,
.num_modes = 1,
.size = {
.width = 320,
.height = 187,
},
};
static const struct of_device_id platform_of_match[] = {
[...]
}, {
.compatible = "lg,lp097qx1-spa1",
.data = &lg_lp097qx1_spa1,
}, {
[...]
}方式二：
使用display-timings结构, 直接把timing写在dts文件中, 这类适用于简单的屏配置
panel: panel {
compatible = "simple-panel-dsi";
ddc-i2c-bus = <&panelddc>;
power-supply = <&vdd_pnl_reg>;
enable-gpios = <&gpio 90 0>;
backlight = <&backlight>;
dsi,flags = <MIPI_DSI_MODE_VIDEO |
MIPI_DSI_MODE_VIDEO_BURST |
MIPI_DSI_MODE_VIDEO_SYNC_PULSE>;
dsi,format = <MIPI_DSI_FMT_RGB888>;
dsi,lanes = <4>;
delay,prepare = <10>;
delay,enable = <10>;
delay,disable = <10>;
delay,unprepare = <10>;
display-timings {
native-mode = <&timing0>;
timing0: timing0 {
clock-frequency = <160000000>;
hactive = <1200>;
vactive = <1920>;
hback-porch = <21>;
hfront-porch = <120>;
vback-porch = <18>;
vfront-porch = <21>;
hsync-len = <20>;
vsync-len = <3>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <0>;
};
};
};方式三：
不填写任何timing, 直接使用edid来获取timing
panel: panel {
compatible = "simple-panel-dsi";
//compatible = "simple-panel";
ddc-i2c-bus = <&panelddc>;
power-supply = <&vdd_pnl_reg>;
enable-gpios = <&gpio 90 0>;
backlight = <&backlight>;
delay,prepare = <10>;
delay,enable = <10>;
delay,disable = <10>;
delay,unprepare = <10>;
