STRUCT SAMSUNG_PWM_CHIP(9)

💜 struct samsung_pwm_chip(9) 💜

okay bestie, so this is the Kernel API Manual entry for struct samsung_pwm_chip(9) — and yes, that (9) means it lives in section 9, the kernel-dev zone, we love a niche queen. ✨

---

🌸 NAME 🌸

struct samsung_pwm_chip — the private data of a PWM chip. literally its own little diary of secrets. no cap. 🎀

---

✨ SYNOPSIS ✨

struct samsung_pwm_chip {
    struct samsung_pwm_variant variant;
    u8 inverter_mask;
    u8 disabled_mask;
    void __iomem *base;
    struct clk *base_clk;
    struct clk *tclk0;
    struct clk *tclk1;
    struct samsung_pwm_channel channel[SAMSUNG_PWM_NUM];
 };

look at her. iconic. main character energy fr fr. 💅

🦋 MEMBERS 🦋

• variant — a local copy of the hardware variant data. it's giving "screenshot of the hardware's personality so we don't have to keep asking." 💖
• inverter_mask — the inverter status for all channels — one bit per channel. yes bestie, one lil' bit each, they're sharing. 🍓
• disabled_mask — the disabled status for all channels — one bit per channel. same deal, one bit per channel, keeping it fair. ✨
• base — base address of the mapped PWM registers. the address of the whole vibe. 📍
• base_clk — the base clock used to drive the timers. she's the one keeping time, the group chat's mom friend. ⏰
• tclk0 — external clock 0 (can be ERR_PTR if not present). so like, she might be an error pointer. don't take it personally if she's not around 🙈
• tclk1 — external clock 1 (can be ERR_PTR if not present). same energy, clock number two. also can be ERR_PTR, also not personal. 💀
• channel — per channel driver data. and it's an array, channel[SAMSUNG_PWM_NUM], because obviously there's more than one channel, it's a whole squad. 👑

ngl this struct is just private data of the PWM chip — nothing dangerous, nothing deprecated, nothing undefined. she's a calm queen. but bestie, do mind those ERR_PTR clocks, they're a vibe check you actually have to run. 💜

okay that's the whole page, no gatekeeping 💅 — this came from ./drivers/pwm, dated October 2026, and the entry is struct samsung_pwm_chip(9). mwah, love u, bye 🫶🌸
