rk_tsadcv2_initialize(9)

🎀 rk_tsadcv2_initialize(9) 🎀

okay bestie, welcome to the Kernel API Manual entry for rk_tsadcv2_initialize — yes it's a section 9 page, yes it's a kernel-internals moment, and yes we're gonna get through it together 💖

---

✨ NAME ✨

rk_tsadcv2_initialize — literally here to initialize the TASDC Controller. that's the whole job. icon behavior, no notes 💅

---

🌸 SYNOPSIS 🌸

void rk_tsadcv2_initialize (struct regmap *grf , void __iomem *regs ,
enum tshut_polarity tshut_polarity );

like, look at her. void, she returns nothing, she just does the thing. main character energy fr fr 🫶

🦋 ARGUMENTS 🦋

• grf — the general register file 💾 this one gets used to do static set by software. so it's the "write your settings down permanently-ish" friend of the group.
• regs — the base address of the tsadc controller. this is where the party's happening, address-wise. 📍
• tshut_polarity — the hardware-controlled active polarity, and the vibes are literally (0:LOW 1:HIGH). so: 0 means LOW, 1 means HIGH. that's it, that's the choice 🌈

---

🔥 DESCRIPTION 🔥

so here's the little three-step glow-up this function performs, in order, no skipping:

1. Set TSADC_V2_AUTO_PERIOD — configure the interleave between every two accessing of TSADC in normal operation. like the normal-speed rhythm of the thing, iykyk ⭐
2. Set TSADCV2_AUTO_PERIOD_HT — configure the interleave between every two accessing of TSADC after the temperature is higher than COM_SHUT or COM_INT. yeah, the spicy mode has its own timing, obsessed 😳🔥
3. Set TSADCV2_HIGH_INT_DEBOUNCE and TSADC_HIGHT_TSHUT_DEBOUNCE — if the temperature is higher than COMP_INT or COMP_SHUT for "debounce" times, the TSADC controller will generate interrupt or TSHUT. so it's like "u sure? u sure? okay, interrupt." 🙈

notice the second macro in step (3) is spelled TSADC_HIGHT_TSHUT_DEBOUNCE and the first is TSADCV2_HIGH_INT_DEBOUNCE — yep, one says HIGHT, one says HIGH. that's genuinely how they're written, don't come for me, I'm just the messenger 💀

that's the whole group chat, all nine of them, present and accounted for 🧚💜
