2022-05-04ARM: dts: exynos: drop useless 'dma-channels/requests' propertiesKrzysztof Kozlowski1-6/+0
The pl330 DMA controller provides number of DMA channels and requests through its registers, so duplicating this information (with a chance of mistakes) in DTS is pointless. Additionally the DTS used always wrong property names which causes DT schema check failures - the bindings documented 'dma-channels' and 'dma-requests' properties without leading hash sign.

2019-07-01ARM: dts: exynos: Fix imprecise abort on Mali GPU probe on Exynos4210Marek Szyprowski1-22/+0
The PMU module of Mali400 GPU is optional and it looks that it is not present on Exynos4210, because any access to its registers causes external abort. This patch removes "pmu" interrupt for Exynos4210 SoCs, so the driver will skip the PMU module. This fixes following fault during kernel boot: Unhandled fault: imprecise external abort (0x1406) at 0x00000000 (lima_pmu_init) from [<c059e6f8>] (lima_device_init+0x244/0x5a0) (lima_device_init) from [<c059e40c>] (lima_pdev_probe+0x7c/0xd8) (lima_pdev_probe) from [<c05afcb8>] (platform_drv_probe+0x48/0x9c) (platform_drv_probe) from [<c05ad594>] (really_probe+0x1c4/0x400) (really_probe) from [<c05ad988>] (driver_probe_device+0x78/0x1b8) (driver_probe_device) from [<c05add30>] (device_driver_attach+0x58/0x60) (device_driver_attach) from [<c05ade34>] (__driver_attach+0xfc/0x160) (__driver_attach) from [<c05ab650>] (bus_for_each_dev+0x68/0xb4) (bus_for_each_dev) from [<c05ac734>] (bus_add_driver+0x104/0x20c) (bus_add_driver) from [<c05aece0>] (driver_register+0x78/0x10c) (driver_register) from [<c0103214>] (do_one_initcall+0x8c/0x430) (do_one_initcall) from [<c0f01328>] (kernel_init_freeable+0x3c8/0x4d0) (kernel_init_freeable) from [<c0ac3aa0>] (kernel_init+0x8/0x10c) (kernel_init) from [<c01010b4>] (ret_from_fork+0x14/0x20) The PMU module seems to work fine on Exynos4412 SoCs, so the patch also moves the interrupt definitions to exynos4210.dtsi and exynos4412.dtsi respectively, to keep only the common part in exynos4.dtsi.

git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/dt Merge "Samsung DeviceTree updates and improvements for 4.5" from Krzysztof Kozlowski: 1. eMMC/SDIO minor fixes usage of bindings on Snow and Peach Chromebooks. 2. Remove FIMD from Odroid XU3-family because on XU3 it cannot be used yet and on XU3-Lite and XU4 it is not supported. 3. Remove deprecated since June 2013 samsung,exynos5-hdmi. 4. Add support for Pseudo Random Generator on Exynos4 (Trats2 for now). This depends on new SSS clock. 5. Add rotator nodes for Exynos4 and Exynos5. 6. Switch DWC3_1 on Odroid XU3 and XU3-Lite to peripheral mode because now it cannot be used as OTG. 7. Cleanup the G2D usage on Exynos4 and add it to a proper domain in case of Exynos4210. 8. Put MDMA1 in proper domain on Exynos4210 as well. 9.

2015-12-29ARM: dts: Fix power domain for sysmmu-rotator device on exynos4Marek Szyprowski1-1/+0
Rotator device and it's SYSMMU belongs to different power domains on various Exynos4 SoC revisions: LCD0 for 4210 and TOP for 4x12. This patch fixes this by moving power-domains property to exynos4210.dtsi. TOP power domain is always enabled and it is not represented in DTS.
