The host driver link startup callback is called indirectly by ufshcd_probe_hba(). That function applies the auto-hibernation settings by writing hba->ahit into the auto-hibernation control register. Simplify the code for disabling auto-hibernation by setting hba->ahit instead of writing into the auto-hibernation control register. This patch is part of an effort to move all auto-hibernation register changes into the UFSHCI driver core.

/* disable auto H8 */ - reg = ufshcd_readl(hba, REG_AUTO_HIBERNATE_IDLE_TIMER); - reg = reg & (~UFS_AHIT_AH8ITV_MASK); - ufshcd_writel(hba, reg, REG_AUTO_HIBERNATE_IDLE_TIMER); + hba->ahit = 0;
The original code only clears the timer value, not the scale. However, I think it is safe to assume that it meant to clear both. Reviewed-by: Bao D. Nguyen <quic_nguyenb@xxxxxxxxxxx>
