* [PATCH v3 2/2] arm64: dts: rockchip: add HDMI sound node for rk3328-rock64 2019-02-17 17:34 [PATCH v3 1/2] arm64: dts: rockchip: add #sound-dai-cells to HDMI of rk3328 Katsuhiro Suzuki @ 2019-02-17 17:34 ` Katsuhiro Suzuki 2019-03-02 14:19 ` Katsuhiro Suzuki 2019-03-03 13:55 ` [PATCH v3 1/2] arm64: dts: rockchip: add #sound-dai-cells to HDMI of rk3328 Heiko Stuebner 1 sibling, 1 reply; 10+ messages in thread From: Katsuhiro Suzuki @ 2019-02-17 17:34 UTC (permalink / raw) To: Heiko Stuebner, linux-rockchip Cc: Katsuhiro Suzuki, linux-kernel, linux-arm-kernel This patch adds HDMI sound (I2S0) node for rock64. After apply this patch, UART2 will fail to allocate DMA resources but UART driver can work fine without DMA. This error is related to the DMAC of rk3328 (pl330 or compatible). DMAC connected to 16 DMA sources. Each sources have ID number that is called 'Req number' in rk3328 TRM. Currently total 7 sources has been activated as follows: | Req number | Source | Required | | | | channels | |------------+--------+-----------| | 14, 15 | I2S1 | 2ch | | 6, 7 | UART2 | 2ch | | 10 | SPDIF | 1ch | | 8, 9 | SPI0 | 2ch | |------------+--------+-----------| | | Total | 7ch | HDMI audio needs to activate new source I2S0 (Req number 11 and 12). I2S0 can work concurrently with other sources, but rk3328 DMAC can use max 8 channels at same time. If I2S0 is simply activated by this patch, required DMAC channels will be 9. So last one (UART2) cannot allocate the DMA resources. Virt-dma mechanism for pl0330 DMAC driver is needed to fix this problem.

My concern are regarding how to configure a single graph card node to add a hdmi: (and iec958: for spdif) variants using an alsa config file. In LibreELEC I expose HDMI and SPDIF as two different card nodes to simplify applying alsa config files, see [1] and [2] for the alsa config files I use. Do you know how I can configure the hdmi: and iec958: cards and add a "IEC958 Playback" ctl with the combined graph card node? I am also working on NL-PCM/HBR-audio support for dw-hdmi-i2s and it will require "IEC958 Playback" ctl and players such as kodi and mpv only sets AES0-3 for hdmi: and iec958: cards.
