Hi all,

We found UFS host reset flow scale up clk directly without informing 
platform driver. On MTK platform, we need to handle the clk change
whenever happends. Please refer to patch for details.

Additionally, we notice QCOM's driver subscribe clk change and set link
to H8 in ufs_qcom_clk_scale_notify(). Not sure if this change could be 
an issue for QCOM? Maybe check on hba->ufshcd_state before enter H8?

Comments are appreciated
