From: Dinesh Maniyam <[email protected]> In v2025.10, the Agilex clock driver was updated to support clk_enable() and clk_disable() using clock-ID based bitmasks. However, only AGILEX_NAND_CLK was implemented, while the NAND DT node still referenced both nand and nand_x clocks.
Since AGILEX_NAND_X_CLK is not defined in the clock driver or the clock-ID specification, clk_enable() failed during NAND probe. As a result, the Denali NAND controller never completed initialization. Fix this by mapping the NAND X clock to the existing l4_mp clock bitmask, aligning the DT expectations with the clock driver and restoring proper NAND controller initialization.
