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.

mmc: core: Add ignore_crc flag to __mmc_switch

2014-02-23T15:40:30+00:00

Instead of handle specific adaptations, releated to certain switch
operations, inside __mmc_switch, push this to be handled by the caller
instead.

mmc: core: Rename cmd_timeout_ms to busy_timeout

2014-02-23T15:40:26+00:00

To better reflect that the cmd_timeout_ms is directly related to the
busy detection timeout, let's rename it.

mmc: core: Do not poll for busy with status cmd for all switch cmds

2013-10-31T00:26:24+00:00

Some switch operations like poweroff notify, shall according to the
spec not be followed by any other new commands. For these cases and
when the host does'nt support MMC_CAP_WAIT_WHILE_BUSY, we must not
send status commands to poll for busy detection. Instead wait for
the stated timeout from the EXT_CSD before completing the request.

mmc: block: Enable runtime pm for mmc blkdevice

2013-05-26T18:23:16+00:00

Once the mmc blkdevice is being probed, runtime pm will be enabled.
By using runtime autosuspend, the power save operations can be done
when request inactivity occurs for a certain time. Right now the
selected timeout value is set to 3 s. Obviously this value will likely
need to be configurable somehow since it needs to be trimmed depending
on the power save algorithm.

For SD-combo cards, we are still leaving the enablement of runtime PM
to the SDIO init sequence since it depends on the capabilities of the
SDIO func driver.

Moreover, when the blk device is being suspended, we make sure the device
will be runtime resumed. The reason for doing this is that we want the
host suspend sequence to be unaware of any runtime power save operations
done for the card in this phase. Thus it can just handle the suspend as
the card is fully powered from a runtime perspective.

Finally, this patch prepares to make it possible to move BKOPS handling
into the runtime callbacks for the mmc bus_ops. Thus IDLE BKOPS can be
accomplished.
