Shreesh Chhabbi fbad99f347 soc/intel/tgl: Update S0ix enable mask based on SoC and mainboard design ... This change uses the following information to determine the appropriate S0ix states to enable as per PDG document: 607872 for TGL UP3 UP Rev2p2 (section 10.13): 1. SoC - UP3 v/s UP4 2. H/W design - external phy gating, external clk gating, external bypass 3. Devices enabled at runtime - CNVi, ISH In some cases, it is recommended to use a shallower state for S0ix even if the higher state can be achieved (e.g. with external gating not enabled). This recommendation is because the shallower state is determined to provide better power savings as per the above document. Deepest state expected on tigerlake up3 based platforms is S0i3.2. BUG=b:177821896 TEST=Build coreboot for volteer. Verify that deepest S0ix substate that is enabled is S0i3.1 Signed-off-by: Shreesh Chhabbi <shreesh.chhabbi@intel.corp-partner.google.com> Change-Id: I5f2ac8b72d0c9b05bc02c092188d0c742cc83af9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/49766 Reviewed-by: Wonkyu Kim <wonkyu.kim@intel.com> Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>		2021-02-10 07:23:09 +00:00
