STRUCT MTK_DPI_CONF(9)

💖 struct mtk_dpi_conf(9) 💖

okay bestie, welcome to the Kernel API Manual moment for struct mtk_dpi_conf — literally the configuration of mediatek dpi, and yes she has a lot of fields, but we’re gonna get through every single one together. 🫶✨

🌸 NAME 🌸

struct mtk_dpi_conf — Configuration of mediatek dpi. That’s the whole vibe, no cap. 💅

🦋 SYNOPSIS 🦋

okay so here’s the struct in all her glory, copied exactly so you can trust it:

       struct mtk_dpi_conf {
           const struct mtk_dpi_factor *dpi_factor;
           const u8 num_dpi_factor;
           u32 reg_h_fre_con;
           u32 max_clock_khz;
           bool edge_sel_en;
           const u32 *output_fmts;
           u32 num_output_fmts;
           bool is_ck_de_pol;
           bool swap_input_support;
           bool support_direct_pin;
           u32 dimension_mask;
           u32 hvsize_mask;
           u32 channel_swap_shift;
           u32 yuv422_en_bit;
           u32 csc_enable_bit;
           u32 input_2p_en_bit;
           u32 pixels_per_iter;
           bool edge_cfg_in_mmsys;
           bool clocked_by_hdmi;
           bool output_1pixel;
        };

🎀 Members 🎀

every field, bestie — no skips, no cap:

• dpi_factor — SoC-specific pixel clock PLL factor values. iconic.
• num_dpi_factor — Number of pixel clock PLL factor values. ✨
• reg_h_fre_con — Register address of frequency control. 📍
• max_clock_khz — Max clock frequency supported for this SoCs in khz units.
• edge_sel_en — Enable of edge selection.
• output_fmts — Array of supported output formats. 🌈
• num_output_fmts — Quantity of supported output formats.
• is_ck_de_pol — Support CK/DE polarity. 💅
• swap_input_support — Support input swap function.
• support_direct_pin — IP supports direct connection to dpi panels.
• dimension_mask — Mask used for HWIDTH, HPORCH, VSYNC_WIDTH and VSYNC_PORCH (no shift). 📐
• hvsize_mask — Mask of HSIZE and VSIZE mask (no shift).
• channel_swap_shift — Shift value of channel swap.
• yuv422_en_bit — Enable bit of yuv422.
• csc_enable_bit — Enable bit of CSC.
• input_2p_en_bit — Enable bit for input two pixel per round feature. If present, implies that the feature must be enabled. important bestie!
• pixels_per_iter — Quantity of transferred pixels per iteration.
• edge_cfg_in_mmsys — If the edge configuration for DPI's output needs to be set in MMSYS.
• clocked_by_hdmi — HDMI IP outputs clock to dpi_pixel_clk input clock, needed for DPI registers access. 🕰️
• output_1pixel — Enable outputting one pixel per round; if the input is two pixel per round, the DPI hardware will internally transform it to 1T1P. 🔥
