STRUCT OMAP_PRCM_IRQ(9)

💅 NAME 💅

ok so struct omap_prcm_irq — bestie, it's literally just the lil descriptor for one single PRCM interrupt bit. one bit. that's her whole job. and she ate ✨

🎀 SYNOPSIS 🎀

struct omap_prcm_irq {
    const char *name;
    unsigned int offset;
    bool priority;
};

🦋 Members 🦋

• name — a short lil name that says what kind of interrupt this is, like "wkup" or "io" 🏷️
• offset — the bit shift of the interrupt inside the IRQ{ENABLE,STATUS} regs. yes, shift. as in bit position. iykyk 💅
• priority — the whole question: should this interrupt get handled before the ones where priority=false? main character energy or background extra, you decide 👑

🌸 Description 🌸

so this struct describes interrupt bits inside the PRM_IRQ{ENABLE,STATUS}_MPU* registers — that's the whole vibe. 🫶

now here's the tea: on systems with multiple PRM MPU IRQ registers, the bitfields that get read from the registers are concatenated. so on those systems offset could legitimately be > 31 and that's not a bug, that's just how the concatenation goes down. if you wanna know more, go look at omap_prm_irq_handler 😌

and listen — I/O ring interrupts should have priority set to true. no cap. do it. 🔥
