STRUCT OMAP_VC_CHANNEL_CFG(9)

💅 struct omap_vc_channel_cfg(9) — NAME 🎀

okay so bestie, welcome to the Kernel API Manual page for struct omap_vc_channel_cfg, and it's literally exactly what it sounds like: this struct is here to describe the cfg_channel bitfield. that's the whole job. iconic of it honestly 🫶

---

✨ SYNOPSIS ✨

struct omap_vc_channel_cfg {
    u8 sa;
    u8 rav;
    u8 rac;
    u8 racen;
    u8 cmd;
};

like, that's the whole struct. five lil u8 fields, no cap 🦋

---

🌸 Members 🌸

bestie these are the members, memorize them, they're all just bits doing their lil bit (pun intended 😭):

• sa — the bit for the slave address 💌
• rav — the bit for the voltage configuration register ⚡
• rac — the bit for the command configuration register 📝
• racen — the enable bit for RAC 👑
• cmd — the bit for command value set selection 🎯

---

🦋 Description 🦋

so these are the channel configuration bits, and they're common for OMAP3+. and because every OMAP generation wanted to be a lil different (main character energy fr fr), here's where each one keeps its bits:

• OMAP3 register: PRM_VC_CH_CONF
• OMAP4 register: PRM_VC_CFG_CHANNEL
• OMAP5 register: PRM_VC_SMPS_<voltdm>_CONFIG — yes that's <voltdm> as a placeholder, it's a whole vibe check per voltage domain, iykyk 💀

ngl the naming across generations is giving "we changed our minds three times" and honestly? relatable.
