tvp514x_write_regs(9)

💅 tvp514x_write_regs(9) — Kernel API Manual ✨

🌸 NAME 🌸

tvp514x_write_regs — initializes a list of TVP5146/47 registers. That’s the whole assignment, bestie: hand it a reglist and it gets that list initialized. 💖

✨ SYNOPSIS ✨

int tvp514x_write_regs (struct v4l2_subdev *sd , const struct tvp514x_reg reglist[] );

🎀 ARGUMENTS 🎀

• sd — a pointer to the v4l2_subdev struct. That’s the subdev situation right there. 🫶
• reglist — the list of TVP5146/47 registers and values. The main-character list, fr fr. 👑

💖 DESCRIPTION 💖

Okay so this function initializes a list of TVP5146/47 registers, and the list is token-driven. Each token does its own little thing:

• If the token is TOK_TERM, then the entire write operation terminates. Bye-bye, write operation. 💀
• If the token is TOK_DELAY, then a delay of 'val' msec is introduced. A lil pause, no cap. ⏳
• If the token is TOK_SKIP, then the register write is skipped. Not today, register write. 🙈
• If the token is TOK_WRITE, then the register write is performed. Slay, actual write. 🔥

Returns zero if successful, or non-zero otherwise. That’s the vibe check on the return value. 🌈
