-Subject: clk: imx: pll14xx: dynamically configure PLL for
- 393216000/361267200Hz
-
-From: Ahmad Fatoum <a.fatoum@pengutronix.de>
-
-[ Upstream commit 72d00e560d10665e6139c9431956a87ded6e9880 ]
-
-Since commit b09c68dc57c9 ("clk: imx: pll14xx: Support dynamic rates"),
-the driver has the ability to dynamically compute PLL parameters to
-approximate the requested rates. This is not always used, because the
-logic is as follows:
-
- - Check if the target rate is hardcoded in the frequency table
- - Check if varying only kdiv is possible, so switch over is glitch free
- - Compute rate dynamically by iterating over pdiv range
-
-If we skip the frequency table for the 1443x PLL, we find that the
-computed values differ to the hardcoded ones. This can be valid if the
-hardcoded values guarantee for example an earlier lock-in or if the
-divisors are chosen, so that other important rates are more likely to
-be reached glitch-free.
-
-For rates (393216000 and 361267200, this doesn't seem to be the case:
-They are only approximated by existing parameters (393215995 and
-361267196 Hz, respectively) and they aren't reachable glitch-free from
-other hardcoded frequencies. Dropping them from the table allows us
-to lock-in to these frequencies exactly.
-
-This is immediately noticeable because they are the assigned-clock-rates
-for IMX8MN_AUDIO_PLL1 and IMX8MN_AUDIO_PLL2, respectively and a look
-into clk_summary so far showed that they were a few Hz short of the target:
-
-imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
-audio_pll2_out 0 0 0 361267196 0 0 50000 N
-audio_pll1_out 1 1 0 393215995 0 0 50000 Y
-
-and afterwards:
-
-imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
-audio_pll2_out 0 0 0 361267200 0 0 50000 N
-audio_pll1_out 1 1 0 393216000 0 0 50000 Y
-
-This change is equivalent to adding following hardcoded values:
-
- /* rate mdiv pdiv sdiv kdiv */
- PLL_1443X_RATE(393216000, 655, 5, 3, 23593),
- PLL_1443X_RATE(361267200, 497, 33, 0, -16882),
-
