2021-03-27dt-bindings: ddr: Add optional manufacturer and revision ID to LPDDR3Julius Werner
On some platforms, DDR parts are multi-sourced and the exact part number used is not know to either kernel or firmware at build time. Firmware can read identifying information from DDR mode registers at boot time but needs a way to communicate this information to kernel and/or userspace. This patch adds optional properties for this information to the existing "jedec,lpddr3" device tree binding to be used for that purpose.
