clk: nxp: lpc32xx: convert from divider_round_rate() to divider_determine_rate()

2026-02-26T22:59:31+00:00

[ Upstream commit af943663ccc266e6346e5645b13c0fca71d24395 ] The divider_round_rate() function is now deprecated, so let's migrate to divider_determine_rate() instead so that this deprecated API can be removed. Note that when the main function itself was migrated to use determine_rate, this was mistakenly converted to: req->rate = divider_round_rate(...) This is invalid in the case when an error occurs since it can set the rate to a negative value.

clk: nxp: Fix pll0 rate check condition in LPC18xx CGU driver

2025-09-21T19:56:39+00:00

The conditional check for the PLL0 multiplier 'm' used a logical AND instead of OR, making the range check ineffective. This patch replaces && with || to correctly reject invalid values of 'm' that are either less than or equal to 0 or greater than LPC18XX_PLL0_MSEL_MAX. This ensures proper bounds checking during clk rate setting and rounding.
