intel_soc_p..._seq_element(9)

💅 NAME 💅

ok so bestie, welcome to intel_soc_pmic_exec_mipi_pmic_seq_element — it Executes PMIC MIPI sequence ✨ like that's literally her whole job, no cap

This is a page from the Kernel API Manual (iykyk, the (9) girlies) 🎀

---

🌸 SYNOPSIS 🌸

int intel_soc_pmic_exec_mipi_pmic_seq_element (u16 i2c_address , u32
reg_address , u32 value , u32 mask );

---

🦋 ARGUMENTS 🦋

• i2c_address — the I2C client address for the PMIC 🔌 like, where the PMIC even lives on the bus
• reg_address — the PMIC register address 📍 the exact spot we're poking
• value — the new value for the register bits to change ✨ fresh new bits, just dropped
• mask — mask indicating which register bits to change 🎭 the vibe check that says which bits we're actually touching

---

✨ DESCRIPTION ✨

ok so picture this: DSI LCD panels describe an initialization sequence in the i915 VBT (Video BIOS Tables) using so called MIPI sequences 🖥️💫 that's the lore.

One possible element in these sequences is a PMIC specific element of 15 bytes — yes, fifteen, she's specific 👑

This function executes these PMIC specific elements, sending the embedded commands to the PMIC 📨 like she's the messenger, the main character, the go-between fr fr.

Return 0 on success, < 0 on failure 😭 so check that return value bestie, do not ignore her

and that's the whole page 💜 this iconic little manual lives over in ./drivers/acpi/pmic, dated October 2026 🌈 mwah, go execute some sequences responsibly bestie 🎀✨
