HS400 timing values are added for SMDK5420, exynos5420-peach-pit
and exynos5800-peach-pi boards.
This also adds RCLK GPIO line, this gpio should be in pull-down
state.
This also enables HS400 on peach-pi and this updates the clock frequency
to 800MHz to be set as input clock t
Thanks Kukjin for looking into this.
I will rebase on top of your for-next and send again.

CMDQ is a new feature introduced in eMMC5.1, which can be used
for helping improve the read performance.
This patch adds support in mmc block layer and core layer.
The CMDQ requires to send 4 CMDs and 5 interrupts, thus it has additional
SW overhead. When CPU frequency is low, it may impact the r
Use qdepth for mmc request fetching. Currently the request fetching
mechanism indicate the qdepth is only 2.

right now we use sbc to present CMD23. If we want sbc to present
other cmds, then it is not suitable. So change the name to precmd
which means a cmd that needs to be sent before a cmd. So it can sent
any command without misunderstanding

mmc host has a class device which is parent of the card device, also
a children of the low level host device. Right now we have runtime pm
for card device and low level host device, but nothing for this host class
device. So it is impossible to connect the card runtime pm to low level host
runtime
Hello
This serial of patches can implement the eMMC5.1 device command queue feature
even a host controller doesn't support CMDQ. Several weeks ago I submitted RFC
patches for review and collected some review comments. Right now these comments
are fixed thus I submit again as the offical patches. P
