But to support this new design we need a vendor op in _mmc_suspend/_mmc_resume functions to control our feature functionality in suspend/resume paths. Moreover export of few symbols is also needed to make core layer functions accessible to our vendor module. Old discussion for Clock scaling feature : https://patchwork.kernel.org/project/linux-mmc/cover/1571668177-3766-1-git-send-email-rampraka@codeaurora.org/ Old discussion for Partial init feature : https://patchwork.kernel.org/project/linux-mmc/patch/1650963852-4173-1-git-send-email-quic_spathi@quicinc.com/ Hence introduce new vendor op in suspend/resume and export few symbols nedeed for our feature.
