HDMI RX控制器配置:
/* Should work with at least 128MB cma reserved above. */ &hdmirx_ctrler { status = "okay"; /* Effective level used to trigger HPD: 0-low, 1-high */ hpd-trigger-level = <1>; hdmirx-det-gpios = <&gpio1 RK_PD5 GPIO_ACTIVE_LOW>; pinctrl-names = "default"; pinctrl-0 = <&hdmim1_rx &hdmirx_det>; }; hdmi { hdmirx_det: hdmirx-det { rockchip,pins = <1 RK_PD5 RK_FUNC_GPIO &pcfg_pull_up>; }; };板级配置需要与实际硬件电路连接对应: hpd-trigger-level:触发HPD的有效电平,<1>表示RK3588控制引脚和HDMI端口HPD电平状态相 同,<0>则表示相反。
hdmirx-det-gpios:HDMI插入检测引脚,需要根据实际硬件连接配置GPIO和有效电平,低电平 有效时,需要配置pinctrl为内部上拉。 预留内存 RK3588 HDMI RX模块只能使用物理连续内存,需要预留至少128MB的CMA内存: 注:按3840x2160分辨率,RGB888图像格式,4个轮转Buffer计算。
reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; dma_trans: dma-trans@3c000000 { reg = <0x0 0x3c000000 0x0 0x04000000>; }; /* Reserve 256MB memory for hdmirx-controller@fdee0000 */ cma { compatible = "shared-dma-pool"; reusable; reg = <0x0 (256 * 0x100000) 0x0 (256 * 0x100000)>; linux,cma-default; }; };
Audio配置:
hdmiin_dc: hdmiin-dc { compatible = "rockchip,dummy-codec"; #sound-dai-cells = <0>; }; hdmiin-sound { compatible = "simple-audio-card"; simple-audio-card,format = "i2s"; simple-audio-card,name = "rockchip,hdmiin"; simple-audio-card,bitclock-master = <&dailink0_master>; simple-audio-card,frame-master = <&dailink0_master>; status = "okay"; simple-audio-card,cpu { sound-dai = <&i2s7_8ch>; }; dailink0_master: simple-audio-card,codec { sound-dai = <&hdmiin_dc>; }; }; &i2s7_8ch { status = "okay"; };
HDMI IN APK适配方法 packages/apps/rkCamera2 :预览apk,通过framework层与上述TV源数据服务进行交互,该APK在桌面上图标名称为 HdmiIn SDK默认代码HDMI IN功能是关闭的,使能HDMI IN功能,需配置如下属性,开启后会编译含上述APK在内的相关模块:
diff --git a/rk3588s_t/rk3588s_t.mk b/rk3588s_t/rk3588s_t.mk index 3ddc9f3..756fc41 100644 --- a/rk3588s_t/rk3588s_t.mk +++ b/rk3588s_t/rk3588s_t.mk +BOARD_HDMI_IN_SUPPORT := true +BOARD_SHOW_HDMI_SETTING := true
