commit 7d6e10f5d254681983b53d979422c8de3fadbefb upstream. The nregs for i.MX6UL should be 144 per fuse map, correct it.

nvmem: rmem: Use NVMEM_DEVID_AUTO

2023-06-15T11:42:18Z

It is reasonable to declare multiple nvmem blocks. Unless a unique 'id' is passed in for each block there may be name clashes. Avoid this by using the magic token NVMEM_DEVID_AUTO.

nvmem: core: add support for fixed cells layout

2023-06-15T11:42:18Z

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: Rafał Miłecki Reviewed-by: Michael Walle Signed-off-by: Srinivas Kandagatla Message-ID: <20230611140330.154222-26-srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman

nvmem: imx: support i.MX93 OCOTP

2023-06-15T11:42:17Z

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.
