2022-11-17dt-bindings: mtd: partitions: Constrain the list of parsersMiquel Raynal
Parser compatibles cannot be used anywhere, and the list is limited. In order to constrain this list, enumerate them all under the top "partitions" subnode. New parsers will have to add their own compatible here as well.

2022-11-17dt-bindings: mtd: physmap: Reuse the generic definitionsMiquel Raynal
The memory mapped MTD devices also share a lot with all the other MTD devices, so let's share the properties by referencing mtd.yaml. We can then drop mentioning the properties, to the cost of mentioning the possible "sram" node name prefix.

2022-11-17dt-bindings: mtd: ingenic: Mark partitions in the controller node as deprecatedMiquel Raynal
Defining partitions as subnodes of the controller has been deprecated long time ago, but unlike having partitions within the controller node, having an enveloppe named "partitions" (which is not itself within a chip subnode) is not that common, so keep this deprecated definition in this file.

2022-11-17dt-bindings: mtd: nand: Standardize the child node nameMiquel Raynal
In almost all the schema mentioning a NAND chip child node, the name of the subnode contains a single index number. In practice there are currently no controller supporting more than 8 cs so even the [a-f] numbers are not needed. But let's be safe and limit the number of touched files by just allow a single number everywhere, so in practice up to 16 CS at most. This value can anyway be limited in each schema.

2022-11-07dt-bindings: mtd: partitions: support marking rootfs partitionRafał Miłecki
Linux needs to know what to use as root device. On embedded devices with flash the only common way to specify that is cmdline & root= parameter. That solution works with U-Boot which is Linux & cmdline aware but isn't available with all market bootloaders. Also that method is fragile: 1. Requires specific probing order on multi-flash devices 2. Uses hardcoded partitions indexes A lot of devices use different partitioning methods. It may be "fixed-partitions" or some dynamic partitioning (e.g. based on parts table). For such cases allow "linux,rootfs" property to mark correct flash partition.

2022-11-07dt-bindings: mtd: partitions: add TP-Link SafeLoader layoutRafał Miłecki
Most TP-Link home routers use the same partitioning system based on a custom ASCII table. It doesn't seem to have any official name. GPL sources contain tool named simply "make_flash" and Makefile target "FlashMaker". This partitions table format was first found in devices with a custom SafeLoader bootloader so it was called SafeLoader by a community. Later it was ported to other bootloaders but it seems the name sticked. Add binding for describing flashes with SafeLoader partitions table. It allows operating systems to parse it properly and register proper flash layout.

2022-10-29platform/loongarch: laptop: Fix possible UAF and simplify ↵Yang Yingliang
generic_acpi_laptop_init() Currently the return value of 'sub_driver->init' is not checked. If sparse_keymap_setup() called in the init function fails, 'generic_ inputdev' is freed, then it will lead a UAF when using it in generic_ acpi_laptop_init(). Fix it by checking the return value and setting generic_inputdev to NULL after free, so as to avoid double free it. The error code in generic_subdriver_init() is always negative, so the return of generic_subdriver_init() can be simplified.
