STRUCT ROCKCHIP_DP_CHIP_DATA(9)

💅 struct rockchip_dp_chip_data 💅

okay bestie, welcome to the Kernel API Manual — yes, the actual Kernel API Manual, we're in the big leagues now 🎀 — and today's main character is struct rockchip_dp_chip_data. It's a little struct whose whole job is, and I quote, to splite the grf setting of kind of chips. That spelling is canon, we do not correct icons ✨

so like. different Rockchip chips have different grf settings, right? and instead of hardcoding a million branches everywhere, this struct just bundles up the relevant bits (literally) so the driver can pick the right ones per chip type. it's giving organized. it's giving responsible. we love a struct that knows itself 💖

✨ NAME ✨

struct rockchip_dp_chip_data — the one that split(e)s the grf setting of kind of chips 🧚

---

🦋 SYNOPSIS 🦋

struct rockchip_dp_chip_data {
    const struct rockchip_grf_reg_field lcdc_sel;
    const struct rockchip_grf_reg_field edp_mode;
    u32 chip_type;
    u32 reg;
 };

that's the whole thing, no cap. four fields, zero drama, all business 🌸

---

🎀 Members 🎀

• lcdc_sel — the grf register field for lcdc_sel, that's it, that's the field 🫶
• edp_mode — the grf register field for edp_mode, same energy, different register 💫
• chip_type — which specific chip type this entry is for, iykyk 👑
• reg — the register base address, the actual location, the address-address 🔥

ngl the two const struct rockchip_grf_reg_field members are both marked const, so don't come for them and try to reassign. they are who they are 💅

👑 SEE ALSO 👑

• Kernel file ./drivers/gpu/drm/rockchip/analogix_dp-rockchip.c — that's where this whole vibe lives, go read it, it's literally right there 🦋

and that's the page, bestie!! no further reading required, you ate this 💖 stay slay, stay compiled 🌈

sign-off szn: this icon dropped from ./drivers/gpu/drm/rockchip back in October 2026, and it's still serving struct rockc...dp_chip_data(9) realness ✨ ily, go touch some registers 🎀
