STRUCT MTK_CQDMA_DEVICE(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this page is all about struct mtk_cqdma_device, aka The struct holding info describing CQDMA device. that's the name, and it's iconic. 🎀

🌸 SYNOPSIS 🌸

struct mtk_cqdma_device {
    struct dma_device ddev;
    struct clk *clk;
    u32 dma_requests;
    u32 dma_channels;
    struct mtk_cqdma_vchan *vc;
    struct mtk_cqdma_pchan **pc;
};

🎀 Members 🎀

okay bestie, here's the whole squad — every member is important, no skipping. 💅

• ddev — an instance for struct dma_device. it's giving main-character DMA device energy. 🌈
• clk — the clock that device internal is using. internal clock vibes, fr fr. 🕰️
• dma_requests — the number of VCs the device supports to. count 'em. 🔥
• dma_channels — the number of PCs the device supports to. also count 'em. 💜
• vc — the pointer to all available VCs. pointer bestie. 🫶
• pc — the pointer to all the underlying PCs. the underlying ones, periodt. 🦋

🔥 SEE ALSO 🔥
