Cover letter [PATCH 0/2] nvmem: Add Sophgo eFuse driver

Sophgo SoCs such as CV1800B contain eFuses used to store factory-programmed data such as calibration values for the built-in ethernet PHY.

As for CV1800B, HW automatically loads the eFuse content into CONTENT base registers which are organized as 32bit values exposed as MMIO.

Currently, add read support for the eFuse. This is a preparation step for supporting the built-in ethernet phy.

Since the clk support isn't mainlined, so cv1800b DT patches are not included.
