  dt-bindings: memory: SDRAM channel: standardise node name (2025-12-18 17:10:05 +0100)

----------------------------------------------------------------
Memory controller drivers for v6.20

1. Mediatek SMI: Fix old struct device reference leaks during error
   paths and device unbinding.

2. Memory Devicetree bindings: refactor existing LPDDR bindings and add
   bindings for DDR4 SDRAM.  These will be used for example in
   stm32mp257f-ev1 DTS.

----------------------------------------------------------------
Clément Le Goffic (5):
      dt-bindings: memory: factorise LPDDR props into SDRAM props
      dt-bindings: memory: introduce DDR4
      dt-bindings: memory: factorise LPDDR channel binding into SDRAM channel
      dt-bindings: memory: add DDR4 channel compatible
      dt-bindings: memory: SDRAM channel: standardise node name

Johan Hovold (3):
      memory: mtk-smi: fix device leaks on common probe
      memory: mtk-smi: fix device leak on larb probe
      memory: mtk-smi: clean up device link creation
