The driver gives access to a non-volatile memory which keeps (at the moment) information like booting media and temperature calibration data used for thermal measurements. Thank you, Claudiu Beznea Changes in v3: - fixed Documentation and binding files names - used __maybe_unused for mchp_otpc_ids Changes in v2: - updated the bindings (patch 1/2) as follows: - included the device name in files names and updated binding content accordingly - updated the description - removed address-cells, size-cells - removed clock include - use GPL-2.0 OR BSD-2-Clause license - removed OTP_PKT_SAMA7G5_TEMP_CALIB_LEN and keep hardcoded value in examples - updated MAINTAINERS file with new naming of bindings Claudiu Beznea (2): dt-bindings: microchip-otpc: document Microchip OTPC nvmem: microchip-otpc: add support .../nvmem/microchip,sama7g5-otpc.yaml | 50 +++ MAINTAINERS | 8 + drivers/nvmem/Kconfig | 7 + drivers/nvmem/Makefile | 2 + drivers/nvmem/microchip-otpc.c | 288 ++++++++++++++++++ .../nvmem/microchip,sama7g5-otpc.h | 12 + 6 files changed, 367 insertions(+) create mode 100644 Documentation/devicetree/bindings/nvmem/microchip,sama7g5-otpc.yaml create mode 100644 drivers/nvmem/microchip-otpc.c create mode 040000 include/dt-bindings/nvmem create mode 100644 include/dt-bindings/nvmem/microchip,sama7g5-otpc.h
