[PATCH 0/7] Preparations to support SD UHS-II cards

[Jason Lai <jasonlai.genesyslogic@gmail.com>]

From: Jason Lai <jason.lai@genesyslogic.com.tw>

Series [1] that has been posted by Ulf Hansson which provided some guidance
and an overall structure.

Series [2] focused on UHS-II card control side to address Ulf's intention
regarding to "modularising" sd_uhs2.c.

This series is the successor version of post [2], which adopts Ulf's
comments about series [2]:
1. Remove unnecessary debug print.
2. Rephrase description about uhs2_cmd_assemble() in sd_uhs2.c
3. Place UHS-II variables in the appropriate structure.

Kind regards
Jason Lai

------ original cover letter from Ulf's series ------
A series [1] that has been collaborative worked upon by Takahiro Akashi
(Linaro) and Ben Chuang (Genesys Logic) is targeting to add SD UHS-II
support
to the mmc subsystem.

Throughout the reviews, we realized that the changes affecting the mmc core
to
support the UHS-II interface/protocol might not be entirely straightforward
to
implement. Especially, I expressed some concerns about the code that
manages
power on/off, initialization and power management of a SD UHS-II card.

Therefore, I have posted this small series to try to help to put some of
the
foundation in the mmc core in place. Hopefully this can provide some
guidance
and an overall structure, of how I think the code could evolve.

More details are available in the commit messages and through comments in
the
code, for each path.

Kind regards
Uffe
