STRUCT FSL_MC(9)

💖 NAME 💖

struct fsl_mc — the private-data glowup of a "fsl,qoriq-mc" platform device. like, this struct is literally the main character of that device's inner life ✨

🦋 SYNOPSIS 🦋

okay bestie, here's the whole vibe, copied exactly, no cap:

struct fsl_mc {
    struct fsl_mc_device *root_mc_bus_dev;
    u8 num_translation_ranges;
    struct fsl_mc_addr_translation_range *translation_ranges;
    void __iomem *fsl_mc_regs;
 };

🎀 Members 🎀

• root_mc_bus_dev — the fsl-mc device that's out here representing the root DPRC 👑 like the head of the friend group.
• num_translation_ranges — just a count, bestie: how many entries live in addr_translation_ranges. she's keeping tally 💅
• translation_ranges — an array of bus-to-system address translation ranges, i.e. the whole map from bus addresses over to system addresses 🗺️✨
• fsl_mc_regs — the base address of the register bank. the foundation, the roots, the starting point fr fr 🫶
