✨ SYNOPSIS ✨

int spmi_ext_register_writel (struct spmi_device *sdev , u16 addr ,
       const u8 *buf , size_t len );

🫶 ARGUMENTS 🫶

• sdev — SPMI device. The whole vibe starts here, bestie. 💅
• addr — slave register address (16-bit address). Yes, 16-bit — she’s specific. ✨
• buf — buffer containing the data to be transferred to the Slave. The little data suitcase. 🎀
• len — the request number of bytes to read (up to 8 bytes). That’s the wording, no cap — up to 8 bytes. 🦋

🌸 DESCRIPTION 🌸

Writes up to 8 bytes of data to the extended register space of a Slave device using 16-bit address. Lowkey straightforward, highkey important. Basically: extended register space, Slave device, 16-bit address, up to 8 bytes. Periodt. 🔥
