STRUCT SKY81452_BL_PLATFORM_DATA(9)

💖 struct sky81452_bl_platform_data(9) 💖

okay bestie, welcome to the Kernel API Manual — this little icon is all about the struct sky81452_bl_platform_data, aka backlight platform data. no cap, it's the struct that tells the sky81452 backlight driver how to behave, and we're gonna go through every single member together. 🫶

✨ NAME ✨

struct sky81452_bl_platform_data — backlight platform data. literally what it says on the tin. 💅

🌈 SYNOPSIS 🌈

struct sky81452_bl_platform_data {
    const char *name;
    struct gpio_desc *gpiod_enable;
    unsigned int enable;
    bool ignore_pwm;
    bool dpwm_mode;
    bool phase_shift;
    unsigned int short_detection_threshold;
    unsigned int boost_current_limit;
 };

🎀 Members 🎀

• name — the backlight driver name. if it's not defined, the default name is lcd-backlight. so don't stress if you leave it out, bestie 💖
• gpiod_enable — the GPIO descriptor which control the EN pin. that's the enable pin, bestie, it's giving let there be light energy. ✨
• enable — enable mask for current sink channel 1, 2, 3, 4, 5 and 6. yes, all six channels are invited to the party. 👑
• ignore_pwm — true if DPWMI should be ignored. (yes, DPWMI exactly — we don't edit the manpage lore here 🙈)
• dpwm_mode — true is DPWM dimming mode, otherwise Analog dimming mode. pick your dimming vibe. 🌸
• phase_shift — true is phase shift mode. turn it on when you want that phase-shift situation. 🦋
• short_detection_threshold — it should be one of 4, 5, 6 and 7V. those are the only valid values, so don't get creative. 💀
• boost_current_limit — it should be one of 2300, 2750mA. again, keep it to those values, okay? 💅
