Subject: tmio_mmc: map SD control registers after enabling the MFD cell
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=544f277bb849da0ba86cfc4203a4c9139e2cd927;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

tmio_mmc: map SD control registers after enabling the MFD cell

ASIC3 can disable the memory, so we need to wait for mfd_cell->enable
to enable the memory before we can map the SD control registers.
