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.

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.

cscope says there are no callers for mmc_try_claim_host in the kernel.
No reason to keep it.

mmc: core: parse voltage from device-tree

2013-08-26T15:31:40+00:00

Add function to support getting voltage from device-tree.
If voltage-range is specified in device-tree node, this function
will parse it and return the available voltage mask.
