And on v5.3-rc1 :) and I have tested this on db845c, seems to work fine for me Tested-by: Vinod Koul <vkoul@kernel.org> -- ~Vinod
This patchset adds SoC info driver which can provide information such as Chip ID, Chip family and serial number about Qualcomm SoCs to user space via sysfs. Furthermore, it allows userspace to get information about custom attributes and various image version information via debugfs. The patchset cleanly applies on top of v5.2-rc7. Changes since v1: - Align ifdefs to left, remove unnecessary debugfs dir creation check and fix function signatures in patch 3 - Fix comment for teh case when serial number is not available in patch 1 Changes since v2: - Reorder patches [patch five -> patch two] Changes since v3: - Add reviewed-bys from Greg - Fix build warning when debugfs is disabled - Remove extra checks for dir creations in patch 5 Changes since v4: - Added Reviewed-bys in multiple patches - Bunch of nitpick fixes in patch 3 - Major refactoring for using core debugfs functions and eliminating duplicate code in patch 4 and 5 [detailed info can be found under --- in each patch] Changes since v5: - No code changes, fix diff.context setting for formatting patches. Version 4 was adding context at the bottom of the file with 'git am'.
