To work around a DMC/Punit issue on ICL where the driver's ICL_PORT_COMP_DW8/IREFGEN PHY setting is lost when entering/exiting DC6 state, make sure to reinit the PHY whenever disabling DC states. Similarly the driver's PHY/DBUF/CDCLK settings should have been preserved across DC5/6 transitions, so check this on all platforms. This gets rid of the following WARN during suspend: Combo PHY A HW state changed unexpectedly Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190816095523.15800-1-imre.deak@intel.com |
