mfd: mmc: rtsx: Change default tx phase

2013-08-30T12:24:07+00:00

The default phase can meet most cards' requirement, but it is not the
optimal one. In some extreme situation, the rx phase point produced by
the following tuning process will drift quite a distance.
Before tuning UHS card, this patch will set a more proper initial tx
phase point, which is calculated from statistic data, and can achieve
a much better tx signal quality.

mfd: rtsx: Configure to enter a deeper power-saving mode in S3

2013-08-20T08:22:01+00:00

Set a bit to enable rts5227 and rts5249 to enter a deeper internal
power-saving mode in S3, and recover it after resuming.

mfd: rtsx: Clear hardware PFM mode in rtl8411b

2013-08-20T08:22:00+00:00

Clear hw_pfm_en to disable hardware PFM mode, to fix a bug that in some
situation registers in 0xFDxx domain can't be accessed.

mfd: rtsx: Add shutdown callback in rtsx_pci_driver

2013-08-20T08:22:00+00:00

Some actions to clear power state should be handled in .shutdown
callback in rtsx_pci_driver. This patch adopts the following measures to
catch this goal:
1. Add a function rtsx_pci_power_off to abstract the common ops in
.shutdown and .suspend
2. Add pcr->ops->force_power_down to fulfill the individual action for
each reader model

mfd: rtsx: Read vendor setting from config space

2013-08-20T08:22:00+00:00

Normally OEMs will set vendor setting to the config space of Realtek
card reader in BIOS stage. This patch reads the setting at the first,
and configure the internal registers according to it, to improve card
reader's compatibility condition.

mfd: rtsx: Add support for RTL8411B

2013-06-11T17:27:51+00:00

Adding support of model RTL8411B. Since the model is similar to RTL8411,
differences are implemented in rtl8411.c.

mfd: rtsx: Implement driving adjustment to device-dependent callbacks

2013-02-13T23:22:59+00:00

Implement different ways of selecting driving capability(a necessary adjustment
along with voltage change). It was origionally in device-independent
mmc/host/rtsx_pci_sdmmc.c. Moving it here to support devices which may have a
different way of adjustment.

mfd: rtsx: Add clock divider hook

2013-01-27T00:30:20+00:00

Add callback function conv_clk_and_div_n to convert between SSC clock
and its divider N.
For rtl8411, the formula to calculate SSC clock divider N is different
with the other card reader models.

mfd: rtsx: Add output voltage switch hook

2013-01-27T00:29:39+00:00

Different card reader has different method to switch output voltage,
add this callback to let the card reader implement its individual switch
function.
This is needed as rtl8411 has a specific switch output voltage procedure.
