STRUCT ROCKCHIP_CHG_DET_REG(9)

💖 struct rockchip_chg_det_reg(9) 💖

okay so bestie, this one's straight out of the Kernel API Manual — like, the manual name is literally struct rockchip_chg_det_reg(9) — and it's giving "the USB charger detect registers" and nothing else. No cap, it's a struct, it holds registers, and it's here to detect chargers. Let's get into it 🫶

🌸 NAME 🌸

struct rockchip_chg_det_reg — usb charger detect registers. That's the whole vibe. It's the little bundle of registers that figures out what kind of USB thing you just plugged in 🔌✨

✨ SYNOPSIS ✨

struct rockchip_chg_det_reg {
    struct usb2phy_reg      cp_det;
    struct usb2phy_reg      dcp_det;
    struct usb2phy_reg      dp_det;
    struct usb2phy_reg      idm_sink_en;
    struct usb2phy_reg      idp_sink_en;
    struct usb2phy_reg      idp_src_en;
    struct usb2phy_reg      rdm_pdwn_en;
    struct usb2phy_reg      vdm_src_en;
    struct usb2phy_reg      vdp_src_en;
    struct usb2phy_reg      opmode;
};

Like, ten fields, all of them struct usb2phy_reg, all of them doing their little job. Obsessed with how tidy that is 💅

🎀 Members 🎀

• cp_det — charging port detected successfully. It ate and left no crumbs ✅
• dcp_det — dedicated charging port detected successfully. The dedicated one showed up and it's main character energy 👑
• dp_det — assert data pin connect successfully. The data pin is connected, periodt.
• idm_sink_en — open dm sink curren. (yes, "curren" — that's literally what it says in here, and honestly? iconic 😭)
• idp_sink_en — open dp sink current.
• idm_sink_en's sibling behavior: it opens the dp sink current, not the dm one — read the field names carefully bestie, iykyk 🙈
• idp_src_en — open dm source current.
• rdm_pdwn_en — open dm pull down resistor. Pull it down, slay 🌈
• vdm_src_en — open dm voltage source. Voltage, but make it dm ⚡
• vdp_src_en — open dp voltage source. Same energy, dp flavored 💜
• opmode — utmi operational mode. This one's the mode switch, the big boss, the vibe check for the whole UTMI situation 🧚

Ngl bestie, the field names are cute but you gotta read them like your life depends on it — idm_sink_en is dm, idp_sink_en is dp, idp_src_en says dm, and rdm_pdwn_en / vdm_src_en / vdp_src_en are all doing their own little dm/dp moment. Copy them exactly, don't "fix" them 💀
