/*
* Rules for modifying this file:
* a) Update of this file should typically correspond to a datamanual revision.
* Datamanual revision that was used should be updated in comment below.
* If there is no update to datamanual, do not update the values. If you
* need to use values different from that recommended by the datamanual
* for your design, then you should consider adding values to the device-
* -tree file for your board directly.
* b) We keep the mode names as close to the datamanual as possible. So
* if the manual calls a mode, DDR50, or DDR or DDR 1.8v or DDR 3.3v,
* we follow that in code too.
* c) If the values change between multiple revisions of silicon, we add
* a revision tag to both the new and old entry. Use 'rev11' for PG 1.1,
* 'rev20' for PG 2.0 and so on.
* d) The node name and node label should be the exact same string. This is
* to curb naming creativity and achieve consistency.
*
* Datamanual Revisions:
*
* DRA76x Silicon Revision 1.0: SPRS993E, Revised December 2018
