From e54c32f8bc7e1c44f7674b29d3db8e5d193b9dad Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 26 Mar 2024 21:58:07 +0200 Subject: [PATCH] ARM: dts: bcm283x: Drop unneeded properties in the bcm2835-firmware node The firmware node contains a "dma-ranges" property to enable usage of the DMA mapping API with its child devices, along with "#address-cells" and "#size-cells" properties to support the dma-ranges. This was needed due to usage of the incorrect device to perform the DMA mapping in drivers. Now that this has been fixed, drop the properties. This effectively reverts commits be08d278eb09 ("ARM: dts: bcm283x: Add cells encoding format to firmware bus") and 55c7c0621078 ("ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations").
