[PATCH V4 0/7] mmc: add error statistics for eMMC and SD card

From: Shaik Sajida Bhanu
Date: Wed Mar 02 2022 - 08:04:17 EST


Changes since V3:
-Dropped error stats feature flag as suggested by Adrain Hunter.
-Separated error state related changes in separate patches as
suggested by Adrain Hunter.
[PATCH V4 4/7] : error state debug fs
[PATCH V4 5/7] : error state enable function
[PATCH V4 6/7] : error state enable in error case
Note: we are enabling error state before calling sdhci_dumpregs
we couldn't add the err state in error stats array as err state
is not error type.
-Corrected Signed-off-by order as suggested by Bjron Andersson.
-Moved error state enable code from sdhci_dumpregs to error
conditions as suggested by Adrain Hunter.

Changes since V2:
-Removed userspace error stats clear debug fs entry as suggested
by Adrain Hunter.
-Split patch into 4 patches
[PATCH V3 1/4] : sdhci driver
[PATCH V3 2/4] : debug fs entries
[PATCH V3 3/4] : core driver
[PATCH V3 4/4] : cqhci driver
-Used for loop to print error messages instead of using printf
statements for all error messages as suggested by Adrain Hunter.
-Introduced one flag to enable error stats feature, if any other
client wants to use this feature, they need to enable that flag.
-Moved reset command timeout error statement to card init flow
as suggested by Adrain Hunter.

Changes since V1:
-Removed sysfs entry for eMMC and SD card error statistics and added
