From b24c8b260189fe21cca992d2f5175a33f6cc5477 Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Tue, 2 Dec 2014 15:42:46 -0800 Subject: 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.
