[PATCH 0/3] nvmem: imx-ocotp: Implement i.MX6ULL/ULZ support

[PATCH 0/3] nvmem: imx-ocotp: Implement i.MX6ULL/ULZ support

[Stefan Wahren]

According to the reference manuals for i.MX6ULL and i.MX6ULZ both SoCs
only support 8 OTP banks instead of 16. So we can't use the compatible
string of i.MX6UL.

[PATCH 1/3] dt-bindings: imx-ocotp: Add i.MX6ULL/ULZ support

[Stefan Wahren]

Since the i.MX6ULL/ULZ only supports 8 OTP banks we need to introduce a new
