If anyone has any objections, please let me know. ------------------ From: Brad Love [ Upstream commit 5ceade1d97fc6687e050c44c257382c192f56276 ] Currently clk_freq is ignored entirely, because the cx235840 driver configures the xtal at the chip defaults. This is an issue if a board is produced with a non-default frequency crystal. If clk_freq is not zero the cx25840 will attempt to use the setting provided, or fall back to defaults otherwise.
