ti_sci_cmd_clk_set_freq(9)

💖 ti_sci_cmd_clk_set_freq 💖

straight from the Kernel API Manual, with main-character energy ✨

🌸 NAME 🌸

ti_sci_cmd_clk_set_freq — Set a frequency for clock. That's the whole assignment, bestie: frequency. clock. setting. iconic. 🎀

✨ SYNOPSIS ✨

int ti_sci_cmd_clk_set_freq (const struct ti_sci_handle *handle , u32
       dev_id , u32 clk_id , u64 min_freq , u64 target_freq , u64 max_freq );

🎀 ARGUMENTS 🎀

vibe check on the args — every single one is doing its job, no cap:

• handle — pointer to TI SCI handle. 🫶
• dev_id — Device identifier this request is for.
• clk_id — Clock identifier for the device for this request. Each device has its own set of clock inputs. This indexes which clock input to modify. 💅
• min_freq — The minimum allowable frequency in Hz. This is the minimum allowable programmed frequency and does not account for clock tolerances and jitter.
• target_freq — The target clock frequency in Hz. A frequency will be processed as close to this target frequency as possible. 🎯
• max_freq — The maximum allowable frequency in Hz. This is the maximum allowable programmed frequency and does not account for clock tolerances and jitter.

quick heads-up, bestie: the min_freq and max_freq descriptions both say they do not account for clock tolerances and jitter. That's important — not me making it up, it's literally in the manual. 🚨

💜 RETURN 💜

Returns 0 if all went well; otherwise it returns the appropriate error value. That's the return vibe. ✅
