This patch is to expose the actual SDCLK frequency in
/sys/kernel/debug/mmcX/ios entry.
For example, if the max clk for a normal speed card is 20MHz
this is reported in /sys/kernel/debug/mmcX/ios.
Unfortunately the actual SDCLK frequency (i.e. Baseclock / divisor)
is not reported at all: for

Enable boot partitions to be power and permanently read-only locked via
a sysfs entry. There will be one sysfs entry for the main mmc device:
/sys/block/mmcblkX/boot_partition_ro_lock
and one for each boot partition:

Hi All,
Let me explain things in detail :-
My INTENT / REQUIREMENT is to test ALL the SD/MMC Commands and NOT
just the Read/Write(data transfer) Commands.
How can this be helpful
1. It can be used to validate the SD/MMC Core flows(Command specific
code paths)
2. The Card Enumeration can be
Runtime PM support is now dynamically controling the
enable/disable of the clock and vcore regulator.
In runtime_suspend the register values are saved and in
runtime_resume register values are restored. We also make
use of the runtime_autosuspend with a timeout value
set to 50 ms.
