770ba14bd7 dt-bindings: reference MC peripheral properties in relevant devices
Several devices can be attached to memory controllers (or memory-mapped
buses), thus they can come with additional controller-specific
properties, e.g. devices wired under Intel IXP4XX bus: cfi-flash,
intel,ixp4xx-compact-flash, NS8250 serial and MAX6369 watchdog.

Referencing Memory Controller or IXP4XX bus peripheral properties fixes
few dtbs_check warnings like:

  intel-ixp42x-gateworks-gw2348.dtb: ide@1,0: Unevaluated properties are not allowed
    ('intel,ixp4xx-eb-ahb-split-transfers', 'intel,ixp4xx-eb-byte-access', ... ' were unexpected)

SPI NOR core changes:
* Add support for flash reset using the dt reset-gpios property.
* Update hwcaps.mask to include 8D-8D-8D read and page program ops
  when xSPI profile 1.0 table is defined.
* Bypass zero erase size in spi_nor_find_best_erase_type().
* Fix select_uniform_erase to skip 0 erase size
* Add generic flash driver. If a flash is not found in the flash_info
  array, fall back to the generic flash driver which is described solely
  by the flash's SFDP tables.
* Fix the number of bytes for the dummy cycles in
  spi_nor_spimem_check_readop().
* Introduce SPI_NOR_QUAD_PP flag, as PP_1_1_4 is not SFDP discoverable.

SPI NOR manufacturer drivers changes:
* Spansion:
  - use PARSE_SFDP for s28hs512t,
  - add support for s28hl512t, s28hl01gt, and s28hs01gt.

2f05bff26c dt-bindings: mtd: fixed-partitions: Fix 'sercomm,scpart-id' schema
The schema for 'sercomm,scpart-id' is broken. The 'if' condition is
never true because 'compatible' is in the parent node, not the child
node the sub-schema applies to. The example passes as there are no
constraints on additional/unevaluated properties. That's a secondary
issue which is complicated due to nested partitions.

Drop the if/then schema and the unnecessary 'allOf' so that the
'sercomm,scpart-id' property is at least defined.

c0fc45f7d3 dt-bindings: mtd: nvmem-cells: Drop range property from example
Memory mapped devices such as parallel NOR flash could make use of the
'ranges' property to translate a nvmem 'reg' cell address to a CPU
address but in practice there is no upstream user nor any declaration of
this property being valid in this case yet, leading to a warning when
constraining a bit more the schema:

	.../mtd/partitions/nvmem-cells.example.dtb: calibration@f00000:
	Unevaluated properties are not allowed ('ranges' was unexpected)

So let's drop the property from the example, knowing that someone might

73fc632065 dt-bindings: mtd: ingenic: Mark partitions in the controller node as deprecated
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.

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.

2b9a31d762 dt-bindings: mtd: partitions: support marking rootfs partition
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.

132c57b489 dt-bindings: mtd: partitions: add TP-Link SafeLoader layout
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.

EMMC and NAND have the same clock control register named 'SD_EMMC_CLOCK'

a common MMC and NAND sub-clock was discussed and planed to be implemented
as NFC clock provider, but now this series of patches of a common MMC and
NAND sub-clock are never being accepted and the current binding was never
valid. the reasons for giving up are:
1. EMMC and NAND, which are mutually exclusive anyway
2. coupling the EMMC and NAND.
3. it seems that a common MMC and NAND sub-clock is over engineered.
