Hi, This series fixes the several suspend issues on Qcom platforms. Patch 1 fixes the resume failure with spm_lvl=5 suspend on most of the Qcom platforms. For this patch, I couldn't figure out the exact commit that caused the issue. So I used the commit that introduced reinit support as a placeholder. Patch 3 fixes the suspend issue on SM8550 and SM8650 platforms where UFS PHY retention is not supported. Hence the default spm_lvl=3 suspend fails. So this patch configures spm_lvl=5 as the default suspend level to force UFSHC/ device powerdown during suspend. This supersedes the previous series [1] that tried to fix the issue in clock drivers. This series is tested on Qcom SM8550 MTP and Qcom RB5 boards.
