+
+Not just i.MX8M, but all i.MX6/7 (and subtypes) need to reverse the
+MAC address read from fuses. Exceptions are i.MX6SLL and i.MX7ULP which
+do not support ethernet at all.

+Subject: [PATCH] nvmem: rockchip-otp: Add clks and reg_read to rockchip_data
+
+In preparation to support new Rockchip OTP memory devices with different
+clock configurations and register layout, extend rockchip_data struct
+with the related members: clks, num_clks, reg_read.
+
+Additionally, to avoid managing redundant driver data, drop num_clks
+member from rockchip_otp struct and update all references to point to
+the equivalent member in rockchip_data.

+Subject: [PATCH] nvmem: rockchip-otp: Improve probe error handling
+
+Enhance error handling in the probe function by making use of
+dev_err_probe(), which ensures the error code is always printed, in
+addition to the specified error message.

+Subject: [PATCH] nvmem: imx: support i.MX93 OCOTP
+
+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.

+Subject: [PATCH] nvmem: core: add support for fixed cells *layout*
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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
