Ulf Hansson bc94440d4e mmc: atmel-mci: Remove redundant runtime PM calls
Commit 9250aea76b ("mmc: core: Enable runtime PM management of host
devices"), made some calls to the runtime PM API from the driver
redundant. Especially those which deals with runtime PM reference
counting, so let's remove them.

Brent Taylor 93c77d2999 mmc: atmel-mci: Check pdata for NULL before dereferencing it at DMA config
Using an at91sam9g20ek development board with DTS configuration may trigger
a kernel panic because of a NULL pointer dereference exception, while
configuring DMA. Let's fix this by adding a check for pdata before
dereferencing it.

Arnd Bergmann 5fef365b64 mmc: atmel-mci: fix mismatched section on atmci_cleanup_slot
As of 528bc7808f ("mmc: atmel-mci: Release mmc resources on failure in probe"),
the atmci_probe() function calls atmci_cleanup_slot in the failure path.

This causes a new warning whenever the driver is built:

WARNING: drivers/mmc/host/built-in.o(.init.text+0xa04): Section mismatch in reference from the function atmci_probe() to the function .exit.text:atmci_cleanup_slot()
The function __init atmci_probe() references
a function __exit atmci_cleanup_slot().

Gcc correctly warns about this function getting dropped in the link stage
for the built-in case, which would cause undefined behavior when this error
path is hit. The solution is to simply drop the __exit annotation.

Ludovic Desroches 66b512eda7 mmc: atmel-mci: fix timeout errors in SDIO mode when using DMA
With some SDIO devices, timeout errors can happen when reading data.
To solve this issue, the DMA transfer has to be activated before sending
the command to the device. This order is incorrect in PDC mode. So we
have to take care if we are using DMA or PDC to know when to send the
MMC command.

Terry Barnaby bdbc5d0c60 mmc: atmel-mci: pio hang on block errors
The driver is doing, by default, multi-block reads. When a block error
occurs, card/block.c instigates a single block read: "mmcblk0: retrying
using single block read".  It leaves the sg chain intact and just changes
the length attribute for the first sg entry and the overall sg_len
parameter.  When atmci_read_data_pio is called to read the single block
of data it ignores the sg_len and expects to read more than 512 bytes as
it sees there are multiple items in the sg list. No more data comes as
the controller has only been commanded to get one block.

Fix regression introduced by commit 796211b795 ("mmc: atmel-mci: add
pdc support and runtime capabilities detection") which removed the need
for CONFIG_MMC_ATMELMCI_DMA but kept the Kconfig-entry as well as the
compile guards around dma_release_channel() in remove(). Consequently,
DMA is always enabled (if supported), but the DMA-channel is not
released on module unload unless the DMA-config option is selected.

Remove the no longer used CONFIG_MMC_ATMELMCI_DMA option completely.

Merge tag 'headers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC Header cleanups from Olof Johansson:
 "This is a collection of header file cleanups, mostly for OMAP and
  AT91, that keeps moving the platforms in the direction of
  multiplatform by removing the need for mach-dependent header files
  used in drivers and other places."

Fix up mostly trivial conflicts as per Olof.

Hein_Tibosch 6bf2af8cd2 mmc: atmel-mci: AP700x PDC is not connected to MCI
Earlier, atmel-mci was adapted to make use of the peripheral DMA
controller (PDC), in case normal DMA wouldn't work.
( http://comments.gmane.org/gmane.linux.kernel.mmc/9403 )

This works OK on ARM platforms (AT91), but it broke the driver
for AVR32, the AP700x.  Although the MCI has PDC support, the
connection is not done for AVR chips.

This patch makes the use of PDC depend on !CONFIG_AVR32.

Hein_Tibosch ccdfe6122f mmc: atmel-mci: DMA can be used with other controllers
After the latest changes to atmel-mci, it could not be used with
DMA on the AVR32 platform. This patch will allow to use DMA again
and it will avoid access to MCI register ATMCI_DMA.

Even if the IP version is lower than v3xx and doesn't have the DMA
configuration register, DMA transfers can be used with a different
controller than the Atmel AHB DMA one. For instance, some AVR chips
use the Synopsys DesignWare AHB DMA controller.

Ludovic Desroches 077d40731e mmc: atmel-mci: not busy flag has also to be used for read operations
Even if the datasheet says that the not busy flag has to be used only
for write operations, it's false except for version lesser than v2xx.

Not waiting on the not busy flag for read operations can cause the
controller to hang-up during the initialization of some SD cards
with DMA after the first CMD6 -- the next command is sent too early.
