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

2025-10-19T14:33:38+00:00

[ Upstream commit 1624dead9a4d288a594fdf19735ebfe4bb567cb8 ] 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.

clk: nxp: lpc18xx-cgu: convert from round_rate() to determine_rate()

2025-10-19T14:33:38+00:00

[ Upstream commit b46a3d323a5b7942e65025254c13801d0f475f02 ] The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch on the cover letter of this series.
