This adds support for the "fixed-layout" NVMEM layout binding. It allows defining NVMEM cells in a layout DT node named "nvmem-layout". While NVMEM subsystem supports layout drivers it has been discussed that "fixed-layout" may actually be supperted internally. It's because: 1. It's a very basic layout 2. It allows sharing code with legacy syntax parsing 3. It's safer for soc_device_match() due to -EPROBE_DEFER 4. This will make the syntax transition easier Signed-off-by:

With the introduction of NVMEM layouts, new NVMEM content structures should be defined as such. We should also try to convert / migrate existing NVMEM content bindings to layouts. This commit handles fixed NVMEM cells. So far they had to be defined directly - as device subnodes. With this change it's allowed to put them in the DT node named "nvmem-layout". Having NVMEM cells in separated node is preferred as it draws a nice line between NVMEM device and its content. It results in cleaner bindings. FWIW a very similar situation has happened to MTD devices and their partitions: see commit 5d96ea42 ("dt-bindings: mtd: Clarify all partition subnodes"). Signed-off-by:

Add i.MX93 OCOTP support. i.MX93 OCOTP has two parts: Fuse shadow block(fsb) and fuse managed by ELE. The FSB part could be directly accessed with MMIO, the ELE could only be accessed with ELE API. Currently the ELE API is not ready, so NULL function callback is used, but it was tested with downstream ELE API. Signed-off-by:

Rafał Miłecki authored
Broadcom's NVRAM contains MACs for Ethernet interfaces. Those MACs are usually base addresses that are also used for calculating other MACs. For example if a router vendor decided to use gmac0 it most likely programmed NVRAM of each unit with a proper "et0macaddr" value. That is a base. Ethernet interface is usually connected to switch port. Switch usually includes few LAN ports and a WAN port. MAC of WAN port gets calculated as relative address to the interface one. Offset varies depending on device model. Wireless MACs may also need to be calculated using relevant offsets. To support all those scenarios let MAC NVMEM cells be referenced with an index specifying MAC offset. Disallow additionalProperties while at it. Signed-off-by:

Exposes consumer library functions providing support for interfaces compatible with the venerable Intel 8254 Programmable Interval Timer (PIT). The Intel 8254 PIT first appeared in the early 1980s and was used initially in IBM PC compatibles. The popularity of the original Intel 825x family of chips led to many subsequent variants and clones of the interface in various chips and integrated circuits. Although still popular, interfaces compatible with the Intel 8254 PIT are nowdays typically found embedded in larger VLSI processing chips and FPGA components rather than as discrete ICs. A CONFIG_I8254 Kconfig option is introduced by this patch. Modules wanting access to these i8254 library functions should select this Kconfig option, and import the I8254 symbol namespace.
