STRUCT BH1770_PLATFORM_DATA(9)

💖 struct bh1770_platform_data(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for struct bh1770_platform_data, and it's literally the platform data for the bh1770glc driver 🦋 pull up a chair, this one's short and sweet.

✨ NAME ✨

struct bh1770_platform_data — platform data for bh1770glc driver

---

🌸 SYNOPSIS 🌸

struct bh1770_platform_data {
  #define BH1770_LED_5mA  0;
  #define BH1770_LED_10mA 1;
  #define BH1770_LED_20mA 2;
  #define BH1770_LED_50mA 3;
  #define BH1770_LED_100mA 4;
  #define BH1770_LED_150mA 5;
  #define BH1770_LED_200mA 6;
    __u8 led_def_curr;
  #define BH1770_NEUTRAL_GA 16384 ;
    __u32 glass_attenuation;
    int (*setup_resources)(void);
    int (*release_resources)(void);
 };

like yes, the #defines are inside the struct body in this listing — that's exactly how it's written here, don't come for me, I'm just the messenger 💅

🎀 Members 🎀

• led_def_curr — the IR led driving current. that's it, that's the whole vibe. 🔥
• glass_attenuation — the attenuation factor for the covering window. iykyk, glass in front of your sensor changes the numbers 👑
• setup_resources — call back for interrupt line setup function 🫶
• release_resources — call back for interrupte line release function 😭 (yes, "interrupte" — that's genuinely what the page says, I'm not fixing it, lowkey iconic)

---

⭐ Description ⭐

here's the example for glass_attenuation, and ngl it's the only example so pay attention bestie:

16384 * 385 / 100 means attenuation factor of 3.85.

i.e.

light_above_sensor = light_above_cover_window / 3.85

so the light reading above the sensor is the light above the cover window divided by 3.85 — fr fr, that's the whole point of the factor. ✨

and that's the page, bestie, you ate that 💀🌸

cute little sign-off: this one lives in ./include/linux/platform_data, dated October 2026, and it's struct bh1770_platform_data(9) all the way down 🎀💜
