omap2_wd_timer_reset(9)

💅 omap2_wd_timer_reset — that’s the Kernel API Manual, bestie 💅

🎀 NAME 🎀

omap2_wd_timer_reset — reset and disable the WDTIMER IP block. slay.

---

✨ SYNOPSIS ✨

int omap2_wd_timer_reset (struct omap_hwmod *oh );

---

🌸 ARGUMENTS 🌸

• oh — it’s a struct omap_hwmod *. that’s the whole argument, no cap.

---

🦋 DESCRIPTION 🦋

okay so after the WDTIMER IP blocks are reset on OMAP2/3, we must also take care to execute the special watchdog disable sequence. why? because the watchdog is re-armed upon OCP softreset. iconic behavior, honestly. (on OMAP4, this behavior was apparently changed and the watchdog is no longer re-armed after an OCP soft-reset. good for OMAP4, i guess 💅)

it returns -ETIMEDOUT if the reset did not complete, or 0 upon success.

XXX Most of this code should be moved to omap_hwmod.c layer during a normal merge window. omap_hwmod_softreset should be renamed to omap_hwmod_set_ocp_softreset, and omap_hwmod_softreset should call the hwmod _ocp_softreset code. noted, bestie 🫶

🔁 RETURN 🔁

0 on success or -errno value on error. periodt.
