From: Primoz Fiser Date: Thu, 7 Aug 2025 13:13:53 +0000 (+0200) Subject: imx9: soc: Reuse and export low_drive_freq_update() X-Git-Tag: v2025.10-rc2~6^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=442e752854bfbcfa9b7ac49eeecce33fb134ed95;p=pandora-u-boot.git imx9: soc: Reuse and export low_drive_freq_update() Reuse and export low_drive_freq_update() function. This way global imx9 board_fix_fdt() doesn't duplicate code. While low_drive_freq_update() can be reused on boards such as phyCORE-i.MX93 (TARGET_PHYCORE_IMX93) which is not using the global imx9 board_fix_fdt() implementation. While at it, make printout logic less verbose by only outputting on the error condition and not on each successful clock fixup. Also drop now invalid comment (low_drive_freq_update() now does fixup for internal and kernel device-tree).
