In summary, X13s needs the following reviewing patches to be backported in the current stable tree [v6.5]: Link: https://lore.kernel.org/lkml/072b3df6-09fb-98a8-2b58-41dfcabd98c0@gmail.com/... This series adds basic support for the QSEECOM interface used to communicate with secure applications running in the TrustZone on certain Qualcomm devices. In addition to that, it also provides a driver for "uefisecapp", the secure application managing access to UEFI variables on such platforms. .... <snip> .....

The UEFI firmware of X13s has clk DT overlays that do not match the upstream DT (See as below example). Here we will need a downstream patch in order to enable audio system (LPASS) on X13s.
So how is this going to be handled in upstream? IOW, why do we need a downstream patch and keep upstream broken? -- You are receiving this mail because: You are on the CC list for the bug.

I think this issue must be fixed in Lenovo UEFI firmware since Lenovo should follow the upstream dt-bindings (since v6.5): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Docu... I will contact ARM & Lenovo to see if this issue can be fixed in later releases. -- You are receiving this mail because: You are on the CC list for the bug.

The compatible mismatch issue is now fixed in X13s UEFI FW v1.58.
I have dropped the workaround patch of lpasscc and confirmed that all QCOM EFI patches will be applied in v6.7-rc1. Let's close this bug, thank you. -- You are receiving this mail because: You are on the CC list for the bug.
