From: Leonard Crestez <[email protected]>
According to NXP Reference Manuals and uboot/atf sources the OCOTP block
on imx8m behaves more like imx6 than imx7.
- Fuses can be read/written 32bits at a time (no imx7-like banking)
- The OCOTP_HW_OCOTP_TIMING register is like imx6 not imx7
Since nvmem doesn't support uboot-style "sense" and "override" this
issue only affected "write" which is very rarely used.
Fixes: 163c0dbd0cb1 ("nvmem: imx-ocotp: add support for imx8mq")
