💅 dw_hdmi_qp_rockchip_bus_fmt_to_reg — NAME ✨

okay so bestie, this is dw_hdmi_qp_rockchip_bus_fmt_to_reg from the Kernel API Manual, and its whole personality is: converts a bus format to a GRF reg value 🎀 like that's literally the job. no cap.

---

🦋 SYNOPSIS 🦋

int __pure dw_hdmi_qp_rockchip_bus_fmt_to_reg (u32 bus_fmt );

she's __pure too, meaning she only looks at her args and nothing else — main character energy fr 💅

---

🌸 ARGUMENTS 🌸

• bus_fmt — one of the MEDIA_BUS_FMT_s allowed by this driver's atomic_check 🫶 that's the vibe check she runs your format against, iykyk.

---

🔥 RETURN 🔥

on success you get an unshifted value to be written to the COLOR_FORMAT GRF register ⭐ — unshifted, meaning no bit-shifting shenanigans, you take it exactly as she hands it to you, periodt.

but if the bus format isn't supported? -EINVAL 😭 she's not mad, she's just disappointed. (jk she's absolutely returning an error, respect it.)

heads up bestie — that -EINVAL is a negative return, so don't go writing it into a register and acting surprised 🙈
