ARC: [dts] fix the errors detected by dtbs_check

2020-11-05T10:43:19+00:00

[ Upstream commit 05b1be68c4d6d76970025e6139bfd735c2256ee5 ] xxx/arc/boot/dts/axs101.dt.yaml: dw-apb-ictl@e0012000: $nodename:0: \ 'dw-apb-ictl@e0012000' does not match '^interrupt-controller(@[0-9a-f,]+)*$' From schema: xxx/interrupt-controller/snps,dw-apb-ictl.yaml The node name of the interrupt controller must start with "interrupt-controller" instead of "dw-apb-ictl".

ARC: [plat-hsdk]: Switch ethernet phy-mode to rgmii-id

2020-09-17T11:47:48+00:00

[ Upstream commit 26907eb605fbc3ba9dbf888f21d9d8d04471271d ] HSDK board has Micrel KSZ9031, recent commit bcf3440c6dd ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") caused a breakdown of Ethernet. Using 'phy-mode = "rgmii"' is not correct because accodring RGMII specification it is necessary to have delay on RX (PHY to MAX) which is not generated in case of "rgmii". Using "rgmii-id" adds necessary delay and solves the issue. Also adding name of PHY placed on HSDK board.

ARC: HSDK: wireup perf irq

2020-09-17T11:47:45+00:00

[ Upstream commit fe81d927b78c4f0557836661d32e41ebc957b024 ] Newer version of HSDK aka HSDK-4xD (with dual issue HS48x4 CPU) wired up the perf interrupt, so enable that in DT. This is OK for old HSDK where this irq is ignored because pct irq is not wired up in hardware. Signed-off-by: Vineet Gupta Signed-off-by: Sasha Levin

ARC: [plat-axs10x]: Add missing multicast filter number to GMAC node

ARC: [plat-hsdk]: allow to switch between AXI DMAC port configurations

2019-08-05T13:55:57+00:00

We want to use DW AXI DMAC on HSDK board in our automated verification to test cache & dma kernel code changes. This is perfect candidate as we don't depend on any external peripherals like MMC card / USB storage / etc. To increase test coverage we want to test both options: * DW AXI DMAC is connected through IOC port & dma direct ops used * DW AXI DMAC is connected to DDR port & dma noncoherent ops used Introduce 'arc_hsdk_axi_dmac_coherent' global variable which can be modified by debugger (same way as we patch 'ioc_enable') to switch between these options without recompiling the kernel. Depend on this value we tweak memory bridge configuration and "dma-coherent" DTS property of DW AXI DMAC. Signed-off-by: Eugeniy Paltsev Acked-by: Alexey Brodkin Signed-off-by: Vineet Gupta

ARC: [haps] Add Virtio support

2019-07-08T08:24:45+00:00

As a preparation for QEMU usage for ARC let's add basic Virtio-MMIO peripherals support for the platform we're going to use. For now we add 5 Virtio slots in .dts and enable block and network devices via Virtio-MMIO. Note even though typically Virtio register set fits in 0x200 bytes we "allocate" here 0x2000 so that it matches ARC's default 8KiB page size and so remapping of that area is done clearly. We also enable DEVTMPFS automount for more convenient use of external root file-stystem. Before that we used to use built-in Initramfs which didn't automount DEVTMPFS anyways so we didn't need that option, while now it starts making sense.
