mmc: MMC_GOLDFISH should depend on HAS_DMA

2015-11-09T12:16:45+00:00

If NO_DMA=y:

    ERROR: dma_unmap_sg [drivers/mmc/host/android-goldfish.ko] undefined!
    ERROR: dma_alloc_coherent [drivers/mmc/host/android-goldfish.ko] undefined!
    ERROR: dma_map_sg [drivers/mmc/host/android-goldfish.ko] undefined!
    ERROR: dma_free_coherent [drivers/mmc/host/android-goldfish.ko] undefined!

Add a dependency on HAS_DMA to fix this.

mmc: mediatek: Preinitialize delay_phase in get_best_delay()

2015-11-09T12:16:44+00:00

drivers/mmc/host/mtk-sd.c: In function ‘get_best_delay’:
drivers/mmc/host/mtk-sd.c:1284: warning: ‘delay_phase.start’ is used uninitialized in this function
drivers/mmc/host/mtk-sd.c:1284: warning: ‘delay_phase.maxlen’ is used uninitialized in this function

If delay is zero, these fields are indeed not initialized.
Let the compiler preinitialize the whole struct to fix this.

mmc: pxamci: fix read-only gpio detection polarity

2015-11-09T12:04:03+00:00

The commit converting pxamci to slot-gpio API inverted the logic of the
read-only gpio. Fix it by inverting the logic again.

Pull spi updates from Mark Brown:
 "Quite a lot of activity in SPI this cycle, almost all of it in drivers
  with a few minor improvements and tweaks in the core.

   - Updates to pxa2xx to support Intel Broxton and multiple chip selects.
   - Support for big endian in the bcm63xx driver.
   - Multiple slave support for the mt8173
   - New driver for the auxiliary SPI controller in bcm2835 SoCs.
   - Support for Layerscale SoCs in the Freescale DSPI driver"

mmc: dw_mmc: fix the wrong setting for UHS-DDR50 mode

2015-10-29T10:00:43+00:00

When card is running with DDR mode, dwmmc needs to set DDR_REG bit at
UHS_REG register.
Before this patch, dwmmc controller doesn't consider this.
If this patch is not applied, CRC or other error shoulds be occurred.

mmc: dw_mmc: fix the CardThreshold boundary at CardThrCtl register

2015-10-29T10:00:37+00:00

According to DesignWare DoC file, CardThreshold bit should be
bit[27:16].
So it's correct to use (0xFFF << 16), not (0x1FFF << 16).

An spi_driver does not need to set an owner, it will be populated by the
