rk_tsadcv3_control(9)

💅 rk_tsadcv3_control — Kernel API Manual, bestie edition 🎀

okay so this page lives in section 9 of the kernel API manual, and it's all about rk_tsadcv3_control. say it with me: rk-tsadc-v3-control. iconic name, honestly.

---

✨ NAME ✨

rk_tsadcv3_control — literally flips the tsadc controller on or off. that's the whole vibe. enabled, or disabled. main character toggle energy 💅

---

🦋 SYNOPSIS 🦋

void rk_tsadcv3_control (void __iomem *regs , bool enable );

no cap, that's the whole signature. void in, void out, nothing returned, just vibes ✨

---

🌸 ARGUMENTS 🌸

• regs — the base address of the tsadc controller. it's a void __iomem *, so like, it's the doorway to the hardware registers. don't lose it 🫶
• enable — a bool flag that enables the controller. so it's giving "on" or "off" and those are genuinely the only two options, periodt.

---

👑 NOTE 👑

real talk, this one matters 👀

The TSADC controller works at auto mode, and some SoCs need set the tsadc_q_sel bit on TSADCV2_AUTO_CON[1]. The (1024 - tsadc_q) as output adc value if setting this bit to enable.

so yeah — auto mode is the default situation, but some SoCs are extra and need that tsadc_q_sel bit flipped before things behave. iykyk 😭
