mmc: core: Move mmc_start_areq() declaration

2017-08-30T13:03:53+00:00

mmc_start_areq() is an internal mmc core API. Move the declaration accordingly. Signed-off-by: Adrian Hunter Signed-off-by: Ulf Hansson

mmc: core: Add members to mmc_request and mmc_data for CQE's

2017-08-30T12:02:01+00:00

Most of the information needed to issue requests to a CQE is already in struct mmc_request and struct mmc_data. Add data block address, some flags, and the task id (tag), and allow for cmd being NULL which it is for CQE tasks. Signed-off-by: Adrian Hunter Signed-off-by: Ulf Hansson

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. Signed-off-by: Linus Walleij Signed-off-by: Ulf Hansson

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

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

Using extern when declaring functions in the public header, core.h, is redundant. Let's just remove the use of it. Signed-off-by: Ulf Hansson Reviewed-by: Linus Walleij Reviewed-by: Shawn Lin

mmc: core: Move erase/trim/discard defines from public core.h to mmc.h

2017-02-13T12:20:22+00:00

As the public mmc.h header already contains similar defines for other mmc commands and arguments, let's move those for erase/trim/discard into here as well. Signed-off-by: Ulf Hansson Reviewed-by: Linus Walleij Reviewed-by: Shawn Lin

mmc: core: Move some host specific public functions to host.h

2017-02-13T12:20:21+00:00

Ideally the public mmc header file, core.h, shouldn't contain interfaces particularly intended to be used by host drivers. Instead those should remain in the host.h header file. Therefore, let's move a couple functions from core.h to host.h. Signed-off-by: Ulf Hansson Reviewed-by: Linus Walleij Reviewed-by: Shawn Lin

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

2017-02-13T12:20:21+00:00

A significant amount of functions are available through the public mmc core.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 header files. This change concentrates on moving the functions into private mmc headers, following changes may continue with additional clean-ups, as an example some functions can be turned into static.

mmc: core: First step in cleaning up public mmc header files

2017-02-13T12:20:19+00:00

This is the first step in cleaning up the public mmc header files. In this change we makes sure each header file builds standalone, as that helps to resolve dependencies. While changing this, it also seems reasonable to stop including other headers from inside a header itself which it don't depend upon. Additionally, in some cases such dependencies are better resolved by forward declaring the needed struct. Signed-off-by: Ulf Hansson Reviewed-by: Shawn Lin

mmc: mmc: Introduce mmc_abort_tuning()

2016-12-05T13:16:22+00:00

If a tuning command times out, the card could still be processing it, which will cause problems for recovery. The eMMC specification says that CMD12 can be used to stop CMD21, so add a function that does that. Signed-off-by: Adrian Hunter Signed-off-by: Ulf Hansson
