It allows gerneral purpose partitions in MMC Device.
And I try to simpliy make mmc_blk_alloc_parts using mmc_part structure
suggested by Andrei Warkentin.
After patching, we can see general purpose partitions like this.
cat /proc/partitions
179 0 847872 mmcblk0
179 192 4096

While using io multiple blocks operations, change the way that sg is built:
use one sg entry for each block instead of aggregating the whole buffer
in a single sg entry.
Using a single sg entry for a multiple block command may lead to
misunderstanding

MMC1 pbias and speed control fix for SDMMC1 extended I/O cell
Rebase to git://github.com/tmlind/linux.git fixes

Hello,
Some MMC controller instances integrated on older OMAP34xx/35xx chips
don't work correctly with multiple-block reads, due to a hardware bug.
This series fixes the problem by adding an MMC capability flag for this
case and making the appropriate changes to the MMC core code and OMAP HSMMC
Due to hardware bugs, some MMC host controllers don't support
multiple-block reads[1]. To resolve, add a new MMC capability flag,
MMC_CAP_NO_MULTI_READ, which can be set by affected host controller
drivers. When this capability is set, all reads will be issued one
sector at a time.
1. See for
When device data indicates that multiple block reads are not supported on
a given HSMMC controller instance, log a message to the console, and
pass the appropriate MMC capability flag to the MMC core.

v2:
Rebased to latest mmc-next branch.
Updated with comments from Adrian Hunter.
This patch is base on [PATCH v5]
The gpio library should return -EPROBE_DEFER in gpio_request
if gpio driver is not ready. If drivers pass this error code through to
their caller (which they really should) then this will ensure that the
probe is retried later when further devices become available.

Existing omap hsmmc driver uses platform_driver_probe in init
function. Change it to use platform_driver_register in order to
use deferral probe mechanism.

Enhancements done to above patch:
- checkpatch warning fixes
- added Kconfig symbol CONFIG_PROBE_DEFER
- replacing normal workqueue with singlethread_workqueue
- handling -EPROBE_DEFER error
Apart from that, OMAP
Add new error value so that drivers can request deferred probe
from drivercore.
