d3204ab995 mmc: core: remove the MMC_DATA_STREAM flag
It's not set to MMC_DATA_STREAM anywhere.
It seems that it had been used with CMD11/CMD20.
But according to Spec, CMD11/CMD20 are obsolete command.

aed26fcafe mmc: sunxi: Enable eMMC HS-DDR (MMC_CAP_1_8V_DDR) support
Now that clock delay settings for 8 bit DDR are correct, and vqmmc
support is available, we can enable MMC_CAP_1_8V_DDR support. This
enables MMC HS-DDR at up to 52 MHz, even if signal voltage switching
is not available.

2a7aa63a27 mmc: sunxi: Support 8 bit eMMC DDR transfer modes
Allwinner's MMC controller needs to run at double the card clock rate
for 8 bit DDR transfer modes. Interestingly, this is not needed for
4 bit DDR transfers.

Different clock delays are needed for 8 bit eMMC DDR, due to the
increased module clock rate. For the A80 though, the same values for
4 bit and 8 bit are shared. The new values for the other SoCs were from
A83T user manual's "new timing mode" default values, which describes
them in clock phase, rather than delay periods. These values were used
without any modification. They may not be correct, but they work.

2dcb305a9e mmc: sunxi: Support MMC_DDR52 timing modes
DDR transfer modes include UHS-1 DDR50 and MMC HS-DDR (or MMC_DDR52).
Consider MMC_DDR52 when setting clock delays.

Since MMC high speed mode goes up to 52 MHz instead of 50 MHz for SD,
and this number is visible in the capability macro, increase the
clock rate upper limit to 52 MHz.

ed9feec72f mmc: sanitize 'bus width' in debug output
The bus width is sometimes the actual bus width, and sometimes indices
to different arrays encoding the bus width. In my debugging case "2"
could mean 8-bit as well as 4-bit, which was extremly confusing. Let's
use the human-readable actual bus width in all places.

77cb7d3a4d mmc: sdhci-iproc: add bcm2835 support
Scott Branden from Broadcom said that the BCM2835 eMMC IP core is
very similar to IPROC and share most of the quirks. So use this driver
instead of separate one.

The sdhci-iproc contains a better workaround for the clock domain
crossing problem which doesn't need any delays. This results in a
better write performance.

Btw we get the rid of the SDHCI_CAPABILITIES hack in the sdhci_readl
function.

358399f8ca mmc: omap_hsmmc: don't print uninitialized variables
When DT based probing is used but the DMA request fails, the
driver will print uninitialized stack data from the rx_req
and tx_req variables, as indicated by this warning:

drivers/mmc/host/omap_hsmmc.c: In function 'omap_hsmmc_probe':
drivers/mmc/host/omap_hsmmc.c:2162:3: warning: 'rx_req' may be used uninitialized in this function [-Wmaybe-uninitialized]
   dev_err(mmc_dev(host->mmc), "unable to obtain RX DMA engine channel %u\n", rx_req);

This removes the DMA request line number from the warning, which
is the easiest solution and won't hurt us any more as we are
planning to remove the legacy code path anyway.

f771f6e832 mmc: sunxi: Support vqmmc regulator
eMMC chips require 2 power supplies, vmmc for internal logic, and vqmmc
for driving output buffers. vqmmc also controls signaling voltage. Most
boards we've seen use the same regulator for both, nevertheless the 2
have different usages, and should be set separately.

This patch adds support for vqmmc regulator supply, including voltage
switching. The MMC core can use this to try different signaling voltages
for eMMC.

Pull staging/android fix from Greg KH:
 "Here is one patch, for the android binder driver, to resolve a
  reported problem.  Turns out it has been around for a while (since
  3.15), so it is good to finally get it resolved.

  It has been in linux-next for a while with no reported issues"

Here are a few USB fixes for 4.5-rc6
 
 They fix a reported bug for some USB 3 devices by reverting the recent
 patch, a MAINTAINERS change for some drivers, some new device ids, and
 of course, the usual bunch of USB gadget driver fixes.
 
 All have been in linux-next for a while with no reported issues.

340b3a5b35 ARM: SoC fixes
We didn't have a batch last week, so this one is slightly larger.
 
 None of them are scary though, a handful of fixes for small DT pieces,
 replacing properties with newer conventions.
 
 Highlights:
 
  - N900 fix for setting system revision
  - onenand init fix to avoid filesystem corruption
  - Clock fix for audio on Beaglebone-x15
  - Fixes on shmobile to deal with CONFIG_DEBUG_RODATA (default y in 4.6)
 
  + misc smaller stuff.
