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.
