And for sdcard slots -it sets the clock in a low-power mode. - -This is causing transmission errors when talking to the sdio-wifi on the -cubietruck, and this may be the cause of problems with some type sdcards -too. This patch fixes things by simply never setting the clk in low power -mode. - -Signed-off-by: Hans de Goede <hdegoede@redhat.com> ---- - drivers/mmc/host/sunxi-mmc.c | 3 --- - drivers/mmc/host/sunxi-mmc.h | 1 - - 2 files changed, 4 deletions(-) - -diff --git a/drivers/mmc/host/sunxi-mmc.c b/drivers/mmc/host/sunxi-mmc.c -index f4bfaf0..c1a9d8a 100644 ---- a/drivers/mmc/host/sunxi-mmc.c -+++ b/drivers/mmc/host/sunxi-mmc.c -@@ -400,9 +400,6 @@ static void sunxi_mmc_oclk_onoff(struct sunxi_mmc_host *host, u32 oclk_en) - if (oclk_en) - rval |= SDXC_CARD_CLOCK_ON; - -- if (!host->io_flag) -- rval |= SDXC_LOW_POWER_ON; -- - mci_writel(host, REG_CLKCR, rval); - - rval = SDXC_START | SDXC_UPCLK_ONLY | SDXC_WAIT_PRE_OVER; -diff --git a/drivers/mmc/host/sunxi-mmc.h b/drivers/mmc/host/sunxi-mmc.h -index cbd6d49..a738850 100644 ---- a/drivers/mmc/host/sunxi-mmc.h -+++ b/drivers/mmc/host/sunxi-mmc.h -@@ -211,7 +211,6 @@ struct sunxi_mmc_host { - - /* flags */ - u32 power_on:1; -- u32 io_flag:1; - u32 wait_dma:1; - - dma_addr_t sg_dma; --- -1.8.5.5 - |
