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 v5.0-rc6. 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 Vaishali Thakkar (5): base: soc: Add serial_number attribute to soc soc: qcom: Add socinfo driver soc: qcom: socinfo: Expose custom attributes soc: qcom: socinfo: Expose image information base: soc: Export soc_device_register/unregister APIs Documentation/ABI/testing/sysfs-devices-soc | 7 + drivers/base/soc.c | 9 + drivers/soc/qcom/Kconfig | 8 + drivers/soc/qcom/Makefile | 1 + drivers/soc/qcom/smem.c | 8 + drivers/soc/qcom/socinfo.c | 605 ++++++++++++++++++++ include/linux/sys_soc.h | 1 + 7 files changed, 639 insertions(+) create mode 100644 drivers/soc/qcom/socinfo.c -- 2.17.1
