[PATCH 0/4] dt-bindings: memory: Describing LPDDR topology

From: Julius Werner
Date: Tue Aug 30 2022 - 21:34:11 EST


This patch series implements a proposal previously discussed on the
mailing list under the topic `[RFC] Correct memory layout reporting for
"jedec,lpddr2" and related bindings`. It adds a new jedec,lpddr-channel
binding which should be used to group nodes of the existing jedec,lpddr
bindings to describe their relative topology on the system and the
amount of chips wired in parallel on each channel, as well as their
different ranks. This also adds bindings for LPDDR4 and LPDDR5 memory
types and deduplicates some common schema elements between different
LPDDR types.

Julius Werner (4):
dt-bindings: memory: Factor out common properties of LPDDR bindings
dt-bindings: memory: Add numeric LPDDR compatible string variant
dt-bindings: memory: Add jedec,lpddr4 and jedec,lpddr5 bindings
dt-bindings: memory: Add jedec,lpddrX-channel binding
