2018-12-21tools/testing/nvdimm: Add test support for Intel nvdimm security DSMsDave Jiang
Add nfit_test support for DSM functions "Get Security State", "Set Passphrase", "Disable Passphrase", "Unlock Unit", "Freeze Lock", and "Secure Erase" for the fake DIMMs. Also adding a sysfs knob in order to put the DIMMs in "locked" state. The order of testing DIMM unlocking would be. 1a. Disable DIMM X. 1b. Set Passphrase to DIMM X. 2. Write to /sys/devices/platform/nfit_test.0/nfit_test_dimm/test_dimmX/lock_dimm 3. Renable DIMM X 4.

With Intel DSM 1.8 [1] two new security DSMs are introduced. Enable/update master passphrase and master secure erase. The master passphrase allows a secure erase to be performed without the user passphrase that is set on the NVDIMM. The commands of master_update and master_erase are added to the sysfs knob in order to initiate the DSMs. They are similar in opeartion mechanism compare to update and erase.

2018-12-21acpi/nfit, libnvdimm/security: Add security DSM overwrite supportDave Jiang
Add support for the NVDIMM_FAMILY_INTEL "ovewrite" capability as described by the Intel DSM spec v1.7. This will allow triggering of overwrite on Intel NVDIMMs. The overwrite operation can take tens of minutes. When the overwrite DSM is issued successfully, the NVDIMMs will be unaccessible. The kernel will do backoff polling to detect when the overwrite process is completed. According to the DSM spec v1.7, the 128G NVDIMMs can take up to 15mins to perform overwrite and larger DIMMs will take longer. Given that overwrite puts the DIMM in an indeterminate state until it completes introduce the NDD_SECURITY_OVERWRITE flag to prevent other operations from executing when overwrite is happening. The NDD_WORK_PENDING flag is added to denote that there is a device reference on the nvdimm device for an async workqueue thread context.

2018-12-21auxdisplay: charlcd: fix x/y command parsingMans Rullgard
The x/y command parsing has been broken since commit 129957069e6a ("staging: panel: Fixed checkpatch warning about simple_strtoul()"). Commit b34050fadb86 ("auxdisplay: charlcd: Fix and clean up handling of x/y commands") fixed some problems by rewriting the parsing code, but also broke things further by removing the check for a complete command before attempting to parse it. As a result, parsing is terminated at the first x or y character. This reinstates the check for a final semicolon. Whereas the original code use strchr(), this is wasteful seeing as the semicolon is always at the end of the buffer. Thus check this character directly instead.

2018-12-21serial/sunsu: fix refcount leakYangtao Li
The function of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. su_get_type() doesn't do that. The match node are used as an identifier to compare against the current node, so we can directly drop the refcount after getting the node from the path as it is not used as pointer.

2018-12-21of: __of_detach_node() - remove node from phandle cacheFrank Rowand
Non-overlay dynamic devicetree node removal may leave the node in the phandle cache. Subsequent calls to of_find_node_by_phandle() will incorrectly find the stale entry. Remove the node from the cache. Add paranoia checks in of_find_node_by_phandle() as a second level of defense (do not return cached node if detached, do not add node to cache if detached).

Use modern cdev_device_add() single code cut down three steps of cdev_add(), device_create(). This further helps to move device sysfs files to class attributes in subsequent patch. 5.

Calling readl directly instead of going through another function that results in the same result to remove some overhead. I didn't try to measure the performance gain, but IMHO there is little benefit from abstracting a GPIO register access in the GPIO driver.

2018-12-21pinctrl: imx8qxp: break the dependency on SOC_IMX8QXPAisheng Dong
ARM64 SoC does not encourage people to add more finegrained SoC config options rather than a single ARCH_<family> in arch Kconfig. So this patch aims to break the dependency on SOC_IMX8QXP.
