mmc: core: remove the MMC_DATA_STREAM flag

2016-02-29T10:03:02+00:00

It's not set to MMC_DATA_STREAM anywhere.
It seems that it had been used with CMD11/CMD20.
But according to Spec, CMD11/CMD20 are obsolete command.

mmc: mmc: extend the mmc_send_tuning()

2015-10-27T09:38:41+00:00

The mmc_execute_tuning() has already prepared the opcode,
there is no need to prepare it again at mmc_send_tuning(),
and, there is a BUG of mmc_send_tuning() to determine the opcode
by bus width, assume eMMC was running at HS200, 4bit mode,
then the mmc_send_tuning() will overwrite the opcode from CMD21
to CMD19, then got error.

in addition, extend an argument of "cmd_error" to allow getting
if there was cmd error when tune response.

mmc: core: Convert __mmc_switch() into an internal core function

2015-10-26T14:59:54+00:00

As there are no users of the __mmc_switch() API, except for the mmc core
itself, let's convert it from an exported function into an internal.

mmc: core: Convert the error field in struct mmc_command|data into an int

2015-04-08T10:10:20+00:00

Everybody expects the error field in the struct mmc_command|data to be
and int but it's actually an unsigned int. Let's convert it into an int
to meet the expectations.

mmc: core: always check status after reset

2015-01-19T08:56:27+00:00

Always check if the card is alive after a successful reset. This allows
us to remove mmc_hw_reset_check(), leaving mmc_hw_reset() as the only
card reset interface.

mmc: core: Let mmc_send_tuning() to take struct mmc_host* as parameter

2014-12-08T08:11:04+00:00

To be able to use mmc_send_tuning() prior the struct mmc_card has been
allocated, let's convert it to take the struct mmc_host* as parameter
instead.

mmc: core: add core-level function for sending tuning commands

2014-11-26T13:36:51+00:00

According to the SD card spec, Add a manual tuning command function
for SDR104/HS200.
Sending command 19 or command 21 to read data and compare with the
tunning block pattern.

This patch will help to decrease some platform private codes in SDHCI
platform_execute_tuning() callbacks.

mmc: core: Remove the redundant mmc_send_ext_csd() API

2014-11-10T11:40:44+00:00

Previous patches has replaced the calls to mmc_send_ext_csd() into
mmc_get_ext_csd(), thus mmc_send_ext_csd() has become redundant. Let's
remove it.

mmc: core: Export mmc_get_ext_csd()

2014-11-10T11:40:43+00:00

Callers of mmc_send_ext_csd() will be able to decrease code duplication
by using mmc_get_ext_csd() instead. Let's make it available.
