💖 dpu_hw_ctl_init(9) 💖

okay so bestie, welcome to the Kernel API Manual page for dpu_hw_ctl_init — this one is lowkey important, so pay attention. 💅✨

🌸 NAME 🌸

dpu_hw_ctl_init — initializes the ctl_path hw driver object. Bestie, it should be called before accessing any ctl_path register. No cap, do that first. 🫶

✨ SYNOPSIS ✨

struct dpu_hw_ctl * dpu_hw_ctl_init (struct drm_device *dev , const struct dpu_ctl_cfg *cfg , void __iomem *addr , const struct dpu_mdss_version *mdss_ver , u32 mixer_count , const struct dpu_lm_cfg *mixer );

🎀 ARGUMENTS 🎀

• dev — the corresponding device for devres management. It's giving “resource ownership” energy. 🫶
• cfg — the ctl_path catalog entry for which the driver object is required. iykyk, it's the catalog entry. 📚
• addr — the mapped register io address of MDP. literally the mapped register io address. 🗺️
• mdss_ver — the dpu core's major and minor versions. version check slay. 🦋
• mixer_count — number of mixers in mixer. count 'em, bestie. 🔢
• mixer — pointer to an array of Layer Mixers defined in the catalog. yes, an array of Layer Mixers, exactly like it says. 💅

🦋 SEE ALSO 🦋
