of_get_drm_...display_mode(9)

✨ NAME ✨

okay so this is the of_get_drm_panel_display_mode page — it's the one that gets you a panel-timing drm_display_mode straight out of devicetree 🦋 (and just so you know, this is the Kernel API Manual, bestie 💅)

🎀 SYNOPSIS 🎀

int of_get_drm_panel_display_mode (struct device_node *np , struct
        drm_display_mode *dmode , u32 *bus_flags );

🌸 ARGUMENTS 🌸

• np — the device_node that's holding your panel-timing spec 📋
• dmode — this one gets set to the return value, iykyk ✨
• bus_flags — the tea on pixelclk, sync and DE polarity 🫶

💖 DESCRIPTION 💖

so the two Device Tree properties width-mm and height-mm are mandatory — like, not optional, they're required, periodt 💀 — and they get read and set right onto the display mode. that's the whole vibe check.

👑 RETURN 👑

Zero on success, negative error code on failure. no cap, that's it. 💅
