Subject: dt-bindings: soc: ti,omap-dmm: Convert to DT schema
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=ffda432eb1503a6002c823094310ab2b887e4fa7;p=thirdparty%2Flinux.git

dt-bindings: soc: ti,omap-dmm: Convert to DT schema

Convert the TI OMAP Dynamic Memory Manager (DMM) dt binding
from text format to DT schema.

During conversion following changes were made:
- Move file from /bindings/arm/omap to /bindings/soc/ti/
- Make the 'ti,hwmods' property optional and mark it deprecated as it is
  no longer used, it is kept to support legacy dtbs.
- Add the missing required property 'interrupts' to example node.

-OMAP Dynamic Memory Manager (DMM) bindings
-
-The dynamic memory manager (DMM) is a module located immediately in front of the
-SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of memory
-accesses such as priority generation amongst initiators, configuration of SDRAM
-interleaving, optimizing transfer of 2D block objects, and provide MMU-like page
-translation for initiators which need contiguous dma bus addresses.
-
-Required properties:
-- compatible:	Should contain "ti,omap4-dmm" for OMAP4 family
-		Should contain "ti,omap5-dmm" for OMAP5 and DRA7x family
-- reg:		Contains DMM register address range (base address and length)
-- interrupts:	Should contain an interrupt-specifier for DMM_IRQ.
-- ti,hwmods:	Name of the hwmod associated to DMM, which is typically "dmm"
-
-Example:
-
-dmm@4e000000 {
-	compatible = "ti,omap4-dmm";
-	reg = <0x4e000000 0x800>;
-	ti,hwmods = "dmm";
-};
