🌸 NAME 🌸

i2s_tdm_prepare_enable_mclk — prepare to enable all mclks, disable them on failure.

like, it hypes up all the mclks and gets them ready to go, but if something goes sideways it cleans up its own mess. no cap, very responsible of it 🫶

🦋 SYNOPSIS 🦋

int i2s_tdm_prepare_enable_mclk (struct rk_i2s_tdm_dev *i2s_tdm );

---

🎀 ARGUMENTS 🎀

• i2s_tdm — the rk_i2s_tdm_dev struct, obviously. that's the whole vibe check right there 💖

⭐ DESCRIPTION ⭐

so here's the tea ☕ — this function attempts to enable all the mclk clocks, but it's lowkey a clean-freak: on failure it cleans up after itself. main character energy fr fr.

it also guarantees to balance its calls — iconic, no notes 👑

returns success (0) or a negative errno. so like, 0 = slay, negative errno = not slay 😭
