 * Rename renesas24x_* functions to r8t49n24x_*
 * Implement determine_rate instead of round_rate
 * Implement prepare/unprepare
 * Use devm_clk_get_optional and ensure clk0, clk1, and xtal are attempted before dev_err_probe
 * Use ffs() in __renesas_bits_to_shift
 * Remove regmap read/write retry
 * More consistent debug logging
 * Resolved many C related naming and initialization issues
Changes in v6:
 * Rebase on v5.15-rc1
 * Ensure Rob's Reviewed-by tag is included
Changes in v5:
 * Rebase on v5.14-rc2
 * Move driver files from clk/renesas to clk
Changes in v4:
 * Add vendor prefix to dt binding compatible property
 * Remove clock-names description in dt binding
 * Remove redundant 'input-' prefix on clock names
 * Clarify the settings property in dt binding, add data type
 * Fix define spacing
Changes in v3:
 * Clarify settings property in device tree bindings schema is optional
Changes in v2:
 * Correct missing semicolon in 8t49n24x-core.c
