+Subject: thermal: qcom: tsens: Add a skeletal TSENS drivers
+
+TSENS is Qualcomms' thermal temperature sensor device. It
+supports reading temperatures from multiple thermal sensors
+present on various QCOM SoCs.
+Calibration data is generally read from a non-volatile memory
+(eeprom) device.
+
+Add a skeleton driver with all the necessary abstractions so
+a variety of qcom device families which support TSENS can
+add driver extensions.
+
+Also add the required device tree bindings which can be used
+to describe the TSENS device in DT.

+Subject: thermal: qcom: tsens-8916: Add support for 8916 family of SoCs
+
+Add support to calibrate sensors on 8916 family and also add common
+functions to read temperature from sensors (This can be reused on
+other SoCs having similar TSENS device)
+The calibration data is read from eeprom using the generic nvmem
+framework apis.
+
+Based on the original code by Siddartha Mohanadoss and Stephen Boyd.

+Subject: thermal: qcom: tsens-8960: Add support for 8960 family of SoCs
+
+8960 family of SoCs have the TSENS device as part of GCC, hence
+the driver probes the virtual child device created by GCC and
+uses the parent to extract all DT properties and reuses the GCC
+regmap.
+
+Also GCC/TSENS are part of a  domain thats not always ON.
+Hence add .suspend and .resume hooks to save and restore some of
+the inited register context.
+
+Also 8960 family have some of the TSENS init sequence thats
+required to be done by the HLOS driver (some later versions of TSENS
+do not export these registers to non-secure world, and hence need
+these initializations to be done by secure bootloaders)
+
+8660 from the same family has just one sensor and hence some register
+offset/layout differences which need special handling in the driver.
+
+Based on the original code from Siddartha Mohanadoss, Stephen Boyd and
+Narendran Rajan.

+Subject: nvmem: core: return error for non word aligned access
+
+nvmem providers have restrictions on register strides, so return error
+when users attempt to read/write buffers with sizes which are less
+than word size.
+
+Without this patch the userspace would continue to try as it does not
+get any error from the nvmem core, resulting in a hang or endless loop
+in userspace.

+Subject: nvmem: core: fix error path in nvmem_add_cells()
+
+The current code fails to nvmem_cell_drop(cells[0]) - even worse, if
+the loop above fails already at i==0, we'll enter an essentially
+infinite loop doing nvmem_cell_drop on cells[-1], cells[-2], ... which
+is unlikely to end well.
+
+Also, we're not freeing the temporary backing array cells on the error
+path.

+Legacy AT24, AT25 EEPROMs are exported in sys so that only root can
