mmc: Adding AUTO_BKOPS_EN bit set for Auto BKOPS support

2017-02-14T08:11:00+00:00

Adding dedicated flag for AUTO_BKOPS in card->ext_csd structure.
Read AUTO_BKOPS bit value from the device EXT_CSD and set to the
card->ext_csd structure.
In mmc_decode_ext_csd() add a print message in case the AUTO_BKOPS

mmc: core: rename mmc_start_req() to *areq()

2017-02-13T12:20:58+00:00

With the coexisting __mmc_start_request(), mmc_start_request()
and __mmc_start_req() it is a bit confusing that mmc_start_req()
actually does not start a normal request, but an asynchronous
request.

Rename it to mmc_start_areq() to make it explicit what the
function is doing, also fix the kerneldoc for this function
while we're at it.

mmc: core: Invent MMC_CAP_3_3V_DDR

2017-02-13T12:20:44+00:00

According the JEDEC specification an eMMC card supporting 1.8V vccq in DDR
mode should also be capable of 3.3V. However, it's been reported that some
mmc hosts supports 3.3V, but not 1.8V.

Currently the mmc core implements an error handling when the host fails to
set 1.8V for vccq, by falling back to 3.3V. Unfortunate, this seems to be
insufficient for some mmc hosts. To enable these to use eMMC DDR mode let's
invent a new mmc cap, MMC_CAP_3_3V_DDR, which tells whether they support
the eMMC 3.3V DDR mode.

In case MMC_CAP_3_3V_DDR is set, but not MMC_CAP_1_8V_DDR, let's change to
remain on the 3.3V, as it's the default voltage level for vccq, set by the
earlier power up sequence.

As this change introduces MMC_CAP_3_3V_DDR, let's take the opportunity to
do some re-formatting of the related defines in the header file.

mmc: core: Don't use extern declarations of public mmc functions

Using extern when declaring functions in the public header, core.h, is

mmc: core: Move public functions from host.h to private headers

2017-02-13T12:20:25+00:00

A significant amount of functions are available through the public mmc
host.h header file. Let's slim down this public mmc interface, as to
prevent users from abusing it, by moving some of the functions to private
mmc host.h header file.

This change concentrates on moving the functions into private mmc headers,
following changes may continue with additional clean-ups.
