_pwrdm_restore_clkdm_state(9)

💅 _pwrdm_restore_clkdm_state(9) 💅

Welcome to the Kernel API Manual, bestie — this page is the whole group-chat explainer for _pwrdm_restore_clkdm_state ✨.

✨ NAME ✨

_pwrdm_restore_clkdm_state — restore the clkdm hwsup state after pwrst change 🦋

🦋 SYNOPSIS 🦋

void _pwrdm_restore_clkdm_state (struct powerdomain *pwrdm , u8
       sleep_switch );

🎀 ARGUMENTS 🎀

• pwrdm — the struct powerdomain * you're operating on, periodt.
• sleep_switch — the return value from _pwrdm_save_clkdm_state_and_activate, no cap.

🌸 DESCRIPTION 🌸

Okay so here's the vibe: this function restores the clockdomain state that got perturbed by _pwrdm_save_clkdm_state_and_activate, and it calls the power state bookkeeping code too. It's called by omap_set_pwrdm_state. 💫

⚠️ NOTE: if the powerdomain contains multiple clockdomains, this assumes that the first associated clockdomain supports either hardware-supervised idle control in the register, or software-supervised sleep. No return value.
