PCIE: tegra: enable ASPM and disable L0s Enable ASPM feature for Tegra12 but keep L0s disabled as its broken. Bug 1483608 Change-Id: Ie1f8c10dc1d95c4b5164f9030aa5560542c81f1b Signed-off-by: Bibek Basu <email@example.com> Reviewed-on: http://git-master/r/391647 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Matthew Pedro <firstname.lastname@example.org>
Later this L0s blocking code is removed. Tegra-K1 manuals do not say anything about L0s being broken. We also found out that on later kernel versions than we currently use (3.10), PCIe driver has L0s whitelist for certain devices.
Is there errata documentation for Tegra-K1 regarding this issue and is this still valid or can we activate L0s?
