lane参数 |
static struct lane_configuration st7785m_wvga_video_lane_config = { 2, 0, 1, 1, 0, 0, 0 }; |
参数解析 |
struct lane_configuration { uint8_t dsi_lanes; uint8_t dsi_lanemap; uint8_t lane0_state; uint8_t lane1_state; uint8_t lane2_state; uint8_t lane3_state; uint8_t force_clk_lane_hs; }; |
lane 通道0 |
更改为lane使用一个的通道需要更改参数为 static struct lane_configuration st7785m_wvga_video_lane_config = { 1, 0, 1, 0, 0, 0, 0 }; |
dtsi配置 |
/home/scooper/workspace2/qis/P313/kernel/msm-3.18/arch/arm/boot/dts/P322/dsi-panel-st7785m-video.dtsi qcom,mdss-dsi-lane-0-state; // qcom,mdss-dsi-lane-1-state; |
基于msm8953屏幕调试
