mmc: add a card-event host operation

2012-12-07T18:55:31+00:00

Some hosts need to perform additional actions upon card insertion or
ejection. Add a host operation to be called from card detection handlers.

mmc: host: Make UHS timing values fully unique

2012-12-06T18:54:46+00:00

Both of MMC_TIMING_LEGACY and MMC_TIMING_UHS_SDR12 are defined
to 0. And ios->timing is set to MMC_TIMING_LEGACY during power up.
But set_ios can't distinguish these two timing if host support
spec 3.0. Just adjust timing values to be different can resolve
this issue without any other impact.

mmc: Standardise capability type

2012-12-06T18:54:44+00:00

There are discrepancies with regards to how MMC capabilities
are carried throughout the subsystem. Let's standardise them
to eliminate any confusion.

mmc: core: Fixup broken suspend and eMMC4.5 power off notify

2012-10-07T21:41:45+00:00

This patch fixes up the broken suspend sequence for eMMC with sleep
support. Additionally it reworks the eMMC4.5 Power Off Notification
feature so it fits together with the existing sleep feature.

The CMD0 based re-initialization of the eMMC at resume is re-introduced
to maintain compatiblity for devices using sleep.

A host shall use MMC_CAP2_POWEROFF_NOTIFY to enable the Power Off
Notification feature. We might be able to remove this cap later on,
if we think that Power Off Notification always is preferred over
sleep, even if the host is not able to cut the eMMC VCCQ power.

mmc: sd: Fix sd current limit setting

2012-07-22T19:25:52+00:00

Host has different current capabilities at different voltages, we need
to record these settings seperately. The defined voltages are 1.8/3.0/3.3.
For other voltages, we do not touch current limit setting.

Before we set the current limit for the sd card, find out the host's
operating voltage first and then find out the current capabilities of
the host at that voltage to set the current limit.

mmc: add a function to get regulators, supplying card's power

2012-07-21T04:02:08+00:00

Add a function to get regulators, supplying card's Vdd and Vccq on a
specific host. If a Vdd supplying regulator is found, the function checks,
whether a valid OCR mask can be obtained from it. The Vccq regulator is
optional. A failure to get it is not fatal.
