STRUCT ARCXCNN_PLATFORM_DATA(9)

🦋 struct arcxcnn_platform_data(9) 🦋

okay bestie, real talk — this is a page out of the Kernel API Manual, and it's the whole glow-up guide for struct arcxcnn_platform_data. she's a platform data struct for the arcxcnn backlight driver and she's literally the main character of your backlight config. let's get into it 💅

✨ NAME ✨

struct arcxcnn_platform_data — and then a dash, and then… nothing. that's it. that's the name. the dash is doing SO much heavy lifting and honestly? she ate. 🎀

🌸 SYNOPSIS 🌸

here's the whole struct, exactly as she lives in the kernel — no edits, no notes, copying her vibe verbatim:

struct arcxcnn_platform_data {
    const char *name;
    u16 initial_brightness;
    u8 leden;
    u8 led_config_0;
    u8 led_config_1;
    u8 dim_freq;
    u8 comp_config;
    u8 filter_config;
    u8 trim_config;
 };

like, look at all those little u8s lined up. so satisfying. tiny byte fields, big main character energy ✨

💖 Members 💖

every single field, no skips, no cap:

• name — the backlight driver name, fr. if you pass NULL it'll just use the default — so you can absolutely be lazy here and the kernel will not judge you 🫶
• initial_brightness — the starting value of the backlight brightness. your very first glow-up, if you will ✨
• leden — the initial LED string enables, and heads up: the upper bit is the global on/off. so this one field is doing two jobs and she's thriving 👑
• led_config_0 — the fading speed, i.e. the period between intensity steps. this is the drama pacing of your fade 🌈
• led_config_1 — misc settings. see the datasheet bestie, that's where the lore lives 📖
• dim_freq — the pwm dimming frequency, but only if you're in pwm mode. conditional queen 💅
• comp_config — more misc config. again: datasheet. iykyk 🙈
• filter_config — the RC/PWM filter config. datasheet, as always 🔍
• trim_config — full scale current trim. yep, you guessed it — datasheet 💀

ngl there are a lot of "see datasheet" up in here, so keep that datasheet tab open. she is required reading, not optional lore 🌸

and that's the whole page, bestie. slay. 💜

signing off with the receipts: this one lives in ./drivers/video/backlight, she's dated October 2026, and she's filed under struct arcxcnn_platform_data(9) in the Kernel API Manual. periodt. 🎀✨
