_set_master_standbymode(9)

✨ _set_master_standbymode (9) — the Kernel API Manual, bestie edition 💅

okay so this is a kernel API manual page, and it's literally from the Kernel API Manual, and we're about to get into the OCP_SYSCONFIG MIDLEMODE field. buckle up, bestie 🎀

---

🌸 SYNOPSIS 🌸

int _set_master_standbymode (struct omap_hwmod *oh , u8 standbymode ,
u32 *v );

---

🦋 ARGUMENTS 🦋

• oh — a struct omap_hwmod *. yep, that's the hwmod in question, main character energy fr ✨
• standbymode — the MIDLEMODE field bits. like, the actual bits you wanna set, no cap 💅
• v — pointer to the register contents you're gonna modify. lowkey important 🫶

---

💖 DESCRIPTION 💖

so what this does is: it updates the master standby mode bits in v to be standbymode for the oh hwmod. iconic behavior, honestly.

⚠️ it does NOT write to the hardware — like, it's just updating the register contents in memory, don't get it twisted bestie 😭

it returns -EINVAL upon error or 0 upon success. that's it, that's the vibe check 🌈

okay this is the part where I list literally every single reference and you're gonna sit there and read all of them because I said so 💀
