Subject: [PATCH 220/752] ARM/dts: am33xx: mcasp: Add new dma register
|
|
location to reg-property
|
|
|
|
This patch adds an optional address range to reg property. The range
|
|
describes the register location for DMA controller on am33xx. The both
|
|
address ranges are named accordingly in the reg-names property.
