STRUCT OMAP_VC_COMMON(9)

🌸 struct omap_vc_common(9) 🌸

Okay so welcome to the Kernel API Manual page for struct omap_vc_common(9), bestie. This is the per-VC register/bitfield data struct, and we're gonna walk through every single field like the main characters they are. 💅

✨ NAME ✨

struct omap_vc_common — per-VC register/bitfield data. That's the whole NAME section, periodt. 🎀

✨ SYNOPSIS ✨

Here's the struct definition, copied exactly because we do not mess with code, no cap:

       struct omap_vc_common {
           u32 cmd_on_mask;
           u32 valid;
           u8 bypass_val_reg;
           u8 data_shift;
           u8 slaveaddr_shift;
           u8 regaddr_shift;
           u8 cmd_on_shift;
           u8 cmd_onlp_shift;
           u8 cmd_ret_shift;
           u8 cmd_off_shift;
           u8 i2c_cfg_reg;
           u8 i2c_cfg_clear_mask;
           u8 i2c_cfg_hsen_mask;
           u8 i2c_mcode_mask;
        };

🎀 Members 🎀

• cmd_on_mask — ON bitmask in PRM_VC_CMD_VAL* register. iykyk, it's a whole mask moment. ✨
• valid — VALID bitmask in PRM_VC_BYPASS_VAL register. Valid bitmask energy, fr fr.
• bypass_val_reg — Offset of PRM_VC_BYPASS_VAL reg from PRM start. Reg-offset vibes. 🦋
• data_shift — DATA field shift in PRM_VC_BYPASS_VAL register. Shift it, bestie. 🌸
• slaveaddr_shift — SLAVEADDR field shift in PRM_VC_BYPASS_VAL register. SLAVEADDR shift moment. 💜
• regaddr_shift — REGADDR field shift in PRM_VC_BYPASS_VAL register. REGADDR shift slay. 🎀
• cmd_on_shift — ON field shift in PRM_VC_CMD_VAL_* register. ON shift, iconic. 🌈
• cmd_onlp_shift — ONLP field shift in PRM_VC_CMD_VAL_* register. ONLP shift, obsessed. ⭐
• cmd_ret_shift — RET field shift in PRM_VC_CMD_VAL_* register. RET shift, periodt. 🔥
• cmd_off_shift — OFF field shift in PRM_VC_CMD_VAL_* register. OFF shift, okay bestie. 💖
• i2c_cfg_reg — I2C configuration register offset. I2C config offset moment. 🧚
• i2c_cfg_clear_mask — high-speed mode bit clear mask in I2C config register. Clear mask, okay? 💀
• i2c_cfg_hsen_mask — high-speed mode bit field mask in I2C config register. High-speed mode field mask, slay. 🍓
• i2c_mcode_mask — MCODE field mask for I2C config register. MCODE mask, iconic. 🫶

💅 Description 💅

Okay so the Description is literally just a double-XXX note, and it's giving "known weirdness" vibes:

⚠️ caveat: XXX One of cmd_on_mask and cmd_on_shift are not needed XXX VALID should probably be a shift, not a mask

That's the whole thing, bestie. No extra lore, no hidden extra claims, just that exact note. 💀
