dfll_init_out_if(9)

💅 dfll_init_out_if 💅

okay bestie, welcome to the Kernel API Manual, section 9 — this page is all about dfll_init_out_if, and it's giving tiny safety-setup-function with main character energy ✨

🎀 NAME 🎀

dfll_init_out_if — prepare DFLL-to-PMIC interface 🫶

✨ SYNOPSIS ✨

void dfll_init_out_if (struct tegra_dfll *td );

🧚 ARGUMENTS 🧚

• td — DFLL instance 💖

💖 DESCRIPTION 💖

okay so picture this: during DFLL driver initialization, or when it's resuming from context loss, this function does the “get the interface ready” moment. It disables the I2C command output to the PMIC, sets safe voltage and output limits, and disables and clears the limit interrupts. Literally all of those things, together, no skipping 🌸
