Hi,
Can any one please look into this & share info about MMC/SD 4.41
Specification for 2.6.32 Linux Kernel.

1) Adding a comment in order to clarify the choice of the locks within

2) As 李想 has pointed out the wait_dma variable was not accessed within the

When there is only one DES available the DMA performs a FIFO reset and waits
until the reinitialization has been completed.
Disabling the SDXC_IDMAC_DES0_DIC bit prevents the DMA from sending an
interrupt after it has finished this reinitialization.
The flags SDXC_IDMAC_DES0_FD and SDXC_IDMAC_DE
Removing a relict from reverse engineering of the Android driver code in

Hello
This patchset was inspired questions from 李想 of Allwinner and incorporates as
well suggestions from Hans related to spin locks.
For example have not all attributes of the shared host object been protected
by the spin lock, this has been changed.
Also some register names and reset behavior hav

This adds logic to the MMC core to set VQMMC. This is expected to be
called by MMC drivers like dw_mmc as part of (or instead of) their
start_signal_voltage_switch() callback.
A few notes:

We've introduced a new helper in the MMC core:
mmc_regulator_set_vqmmc(). Let's use this in dw_mmc. Using this new
helper has some advantages:
1. We get the mmc_regulator_set_vqmmc() behavior of trying to match
VQMMC and VMMC when the signal voltage is 3.3V. This ensures max
compatibility
