H A D | dw_mmc.h | b24c8b26 Tue Dec 02 17:42:46 CST 2014 Doug Anderson <dianders@chromium.org> mmc: dw_mmc: Cleanup disable of low power mode w/ SDIO interrupts
In the patch (9623b5b mmc: dw_mmc: Disable low power mode if SDIO interrupts are used) I added code that disabled the low power mode of dw_mmc when SDIO interrupts are used. That code worked but always felt a little hacky because we ended up disabling low power as a side effect of the first enable_sdio_irq() call. That wouldn't be so bad except that disabling low power involves a complicated process of writing to the CMD/CMDARG registers and that extra process makes it difficult to cleanly the read-modify-write race in dw_mci_enable_sdio_irq() (see future patch in the series).
Change the code to take advantage of the init_card() callback of the mmc core to do this right at bootup.
