Subject[PATCH V8 0/5] mmc: add error statistics for eMMC and SD card
Date
Changes since V7:
- Patch set V6 rebased on Ulf's(Ulf Hansson) master branch instead
of Ulf's (Ulf Hansson) next branch by mistake. So rebased patch
set on Ulf's next branch now as suggested by Adrain Hunter.

Changes since V6:
- Rebased on Ulf's(Ulf Hansson) next branch as suggested by
Adrain Hunter.
- Replaced debugfs_create_file() with debugfs_create_file_unsafe()
as suggested by Adrain Hunter.
- "[V6,5/5] mmc: cqhci: Capture eMMC and SD card errors" not
included in this Patch series as we don't have cqhci changes
on Ulf's(Ulf Hansson)next branch.

Changes since V5:
- Considered all error stats enums to set error state.
- Added missed tuning error related code changes which was
missed in patch set V5 as Adrain Hunter pointed.
- Replaced DEFINE_SIMPLE_ATTRIBUTE with DEFINE_DEBUGFS_ATTRIBUTE
as suggested by Adrain Hunter.

Changes since V4:
- Defined new macro to increment err_stats members when error occured
as suggested by Adrain Hunter.
- Called err_stats members increment function after printing the error
as suggested by Adrain Hunter.
- Considered INDEX and END_BIT errors same as CRC errors as suggested
by Adrain Hunter.
- Removed Null check for host in debug fs functions and Reordered
err_stats declarationas suggested by Adrain Hunter.
- Removed err_state variable stuff and updated err_state debug fs entry
based on the err_stats members state as suggested by Adrain Hunter.

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
debugfs entry as suggested by Adrian Hunter and Ulf Hansson.
