misc: rtsx: Move Realtek Card Reader Driver to misc

2017-11-29T10:16:44+00:00

Because Realtek card reader drivers are pcie and usb drivers, and they bridge mmc subsystem and memstick subsystem, they are not mfd drivers. Greg and Lee Jones had a discussion about where to put the drivers, the result is that misc is a good place for them, so I move all files to misc. If I don't move them to a right place, I can't add any patch for this driver.

mfd: rtsx: Simplify function return logic

2015-10-30T17:19:44+00:00

The invoked functions already return zero on success or a negative errno code so there is no need to open code the logic in the caller. Signed-off-by: Javier Martinez Canillas Signed-off-by: Lee Jones

mfd: rtsx: Using pcr_dbg replace dev_dbg

2015-03-03T16:41:21+00:00

pcr_dbg is a wrapper of dev_dbg, which can save some code, and help to enable/disable debug message static. Signed-off-by: Micky Ching Signed-off-by: Lee Jones

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. Signed-off-by: Wei WANG Signed-off-by: Samuel Ortiz

mfd: rtsx: Move some actions from rtsx_pci_init_hw to individual extra_init_hw

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

These actions are individual for each reader model, so should be put in extra_init_hw instead of rtsx_pci_init_hw. Signed-off-by: Wei WANG Signed-off-by: Samuel Ortiz

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 Signed-off-by: Wei WANG Signed-off-by: Samuel Ortiz

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. Signed-off-by: Wei WANG Signed-off-by: Samuel Ortiz

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. Signed-off-by: Roger Tseng Reviewed-by: Wei WANG Signed-off-by: Samuel Ortiz
