STRUCT ISP_CCP2_CFG(9)

✨ NAME ✨

struct isp_ccp2_cfg — the CCP2 interface configuration struct, bestie 💅✨

So this is the little struct that holds all the vibes for configuring a CCP2 interface. It lives in the Kernel API Manual (section 9, the kernel one — iykyk), and it's genuinely just a tidy little bundle of bitfields plus a lane config. Obsessed 🎀

---

🎀 SYNOPSIS 🎀

Ok so here's literally the whole thing, copy it exactly, no cap:

struct isp_ccp2_cfg {
    unsigned int strobe_clk_pol:1;
    unsigned int crc:1;
    unsigned int ccp2_mode:1;
    unsigned int phy_layer:1;
    unsigned int vpclk_div:2;
    unsigned int vp_clk_pol:1;
    struct isp_csiphy_lanes_cfg lanecfg;
};

Not me pointing out that vpclk_div is the only one with 2 bits — she's got range, the others are all :1 🦋

💜 MEMBERS 💜

Every single field, bestie, in order, nothing skipped 🫶

• strobe_clk_pol — Strobe/clock polarity. 0 = Non Inverted, 1 = Inverted. Simple as that ✨
• crc — Enable the cyclic redundancy check. You want the check? Flip it on 💖
• ccp2_mode — Enable CCP2 compatibility mode. Two moods: ISP_CCP2_MODE_MIPI = MIPI-CSI1 mode, and ISP_CCP2_MODE_CCP2 = CCP2 mode. Pick your fighter 🌸
• phy_layer — Physical layer selection. ISP_CCP2_PHY_DATA_CLOCK = Data/clock physical layer, ISP_CCP2_PHY_DATA_STROBE = Data/strobe physical layer. Main character choice energy 👑
• vpclk_div — Video port output clock control. Yes, that's the whole description, and yes it's the 2-bit one 🔥
• vp_clk_pol — Video port output clock polarity. Clock but make it video port, and pick a polarity 🌈
• lanecfg — CCP2/CSI2 lane configuration, typed as struct isp_csiphy_lanes_cfg. It's giving "the important nested one" ⭐

Heads up bestie: those two-bit and one-bit widths up in the SYNOPSIS are literal — vpclk_div takes :2, everything else in that run takes :1. Don't come for me, that's just how she's written 🙈

And that's the page, bestie 🧚💖 This came from ./drivers/media/platform/ti/om... (the truncated-path source, she's mysterious like that), dated October 2026, and the whole thing is titled struct isp_ccp2_cfg(9) — slay, go configure something iconic 💅👑
