This series adds support for reading AM62P silicon revision from the efuse GP_SW register. The solution reuses the existing uniphier-efuse driver by adding ti,am62p-efuse as a compatible string. The three patches update the devicetree binding to document the new compatible, configure the driver as mandatory builtin for K3 architectures, and extend the driver to support AM62P devices. The uniphier-efuse driver is simple enough to be reused for efuse register reads on the AM62P SoC. Feedback is welcome on whether reusing the uniphier-efuse driver is the preferred solution or if a dedicated AM62P efuse driver would be more appropriate. Patches have been tested on AM62p SK hardware using SR1.0, SR1.1 and SR1.2 silicon.
