STRUCT PL111_VARIANT_DATA(9)

💖 NAME 💖

Okay bestie, this is the struct pl111_variant_data(9) page from the Kernel API Manual — and it literally encodes IP differences. That’s the whole vibe: one struct, all the variant tea. 🫶

✨ SYNOPSIS ✨

struct pl111_variant_data {
    const char *name;
    bool is_pl110;
    bool is_lcdc;
    bool external_bgr;
    bool broken_clockdivider;
    bool broken_vblank;
    bool st_bitmux_control;
    const u32 *formats;
    unsigned int nformats;
    unsigned int fb_depth;
};

🎀 Members 🎀

Member-by-member breakdown, no skips, fr fr:

• name — the name of this variant. Its little label, basically.
• is_pl110 — this is the early PL110 variant.
• is_lcdc — this is the ST Microelectronics Nomadik LCDC variant.
• external_bgr — this is the Versatile Pl110 variant with external BGR/RGB routing.
• broken_clockdivider — the clock divider is broken and we need to use the supplied clock directly. Do not fight it, bestie.
• broken_vblank — the vblank IRQ is broken on this variant.
• st_bitmux_control — this variant is using the ST Micro bitmux extensions to the control register.
• formats — array of supported pixel formats on this variant.
• nformats — the length of the array of supported pixel formats.
• fb_depth — desired depth per pixel on the default framebuffer.
