* dt-bindings: nvmem: imx-ocotp: update the binding to reflect data cellsDong Aisheng2018-03-141-4/+19
| | | | | | | | | | | | | | | | imx-ocotp is implemented based on nvmem which can have data cells as child node. Update the binding doc to reflect it to be more easily understood by users.

* dt-bindings: Remove leading zeros from bindings notationMarco Franchi2017-11-091-1/+1
| | | | | | | | | | | | | | | | Improve the binding example by removing all the leading zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"` Some unnecessary changes were manually fixed.

* nvmem: imx-ocotp: add write supportRichard Leitner2017-04-081-0/+4
| | | | | | | | | | Implement write routine for OCOTP controller found in i.MX6 SoC's. Furthermore add locking to the read function to prevent race conditions. The write routine code is based on the fsl_otp driver from Freescale.
