* si5351: add support for si5351 Adds support for the si5351 I2C programmable clock generator using code from @chiefMarlin which used code from @conotto which somehow never got merged. Thank you everyone! Signed-off-by: deadprogram <ron@hybridgroup.com> * refactor: use regmap instead of legacy package to avoid heap allocations Signed-off-by: deadprogram <ron@hybridgroup.com> --------- Signed-off-by: deadprogram <ron@hybridgroup.com>
