2020-05-05usb: dwc3: gadget: Issue END_TRANSFER to retry isoc transferThinh Nguyen1-1/+35
After a number of unsuccessful start isoc attempts due to bus-expiry status, issue END_TRANSFER command and retry on the next XferNotReady event. Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>
2020-05-05usb: dwc3: gadget: Store resource index of start cmdThinh Nguyen1-3/+6
As long as the START_TRANSFER command completes, it provides the resource index of the endpoint. Use this when we need to issue END_TRANSFER command to an isoc endpoint to retry with a new XferNotReady event.

2020-05-05usb: dwc3: gadget: Properly handle failed kick_transferThinh Nguyen1-8/+16
If dwc3 fails to issue START_TRANSFER/UPDATE_TRANSFER command, then we should properly end an active transfer and give back all the started requests. However if it's for an isoc endpoint, the failure maybe due to bus-expiry status. In this case, don't give back the requests and wait for the next retry.

2020-05-05usb: dwc3: meson-g12a: refactor usb2 phy initNeil Armstrong1-21/+53
Refactor the USB2 PHY init code patch to handle the Amlogic GXL/GXM not having the PHY mode control registers in the Glue but in the PHY registers. The Amlogic GXL/GXM will call phy_set_mode() instead of programming the PHY mode control registers, thus add two new callbacks to the SoC match data.

On the Amlogic GXL/GXM SoCs, only the USB control registers are available, the PHY mode being handled in the PHY registers. Thus, handle the PHY mode registers in separate regmaps and prepare support for Amlogic GXL/GXM SoCs by moving the regmap setup in a callback set in the SoC match data.

2020-05-05usb: dwc3: gadget: Remove unnecessary checksThinh Nguyen1-8/+1
Remove 2 unnecessary checks: 1) A request in the started_list must have its trb field set. So checking for req->trb is unnecessary. 2) An endpoint must have started (and have not ended) for the request to still be in the started_list. There's no point to check if the endpoint is started. We had this check because previously the driver didn't handle the endpoint's started/ended flags for END_TRANSFER command properly. See commit 9f45581f5eec ("usb: dwc3: gadget: early giveback if End Transfer already completed"). Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>
2020-05-05usb: dwc3: gadget: Give back staled requestsThinh Nguyen1-1/+14
If a request is dequeued, the transfer is cancelled. Give back all the started requests. In most scenarios, the function driver dequeues all requests of a transfer when there's a failure. If the function driver follows this, then it's fine. If not, then we'd be skipping TRBs at different points within the dequeue and enqueue pointers, making dequeue/enqueue pointers useless. To enforce and make sure that we're properly skipping TRBs, cancel all the started requests and give back all the cancelled requests to the function drivers.

2020-05-05usb: dwc3: gadget: Properly handle ClearFeature(halt)Thinh Nguyen1-3/+33
DWC3 must not issue CLEAR_STALL command to control endpoints. The controller automatically clears the STALL when it receives the SETUP token. Also, when the driver receives ClearFeature(halt_ep), DWC3 must stop any active transfer from the endpoint and give back all the requests to the function drivers.

2020-04-30i2c: aspeed: Avoid i2c interrupt status clear race condition.ryan_chen1-1/+4
In AST2600 there have a slow peripheral bus between CPU and i2c controller. Therefore GIC i2c interrupt status clear have delay timing, when CPU issue write clear i2c controller interrupt status. To avoid this issue, the driver need have read after write clear at i2c ISR.

2020-04-29iommu: spapr_tce: Disable compile testing to fix build on book3s_32 configKrzysztof Kozlowski1-1/+1
Although SPAPR_TCE_IOMMU itself can be compile tested on certain PowerPC configurations, its presence makes arch/powerpc/kvm/Makefile to select modules which do not build in such configuration. The arch/powerpc/kvm/ modules use kvm_arch.spapr_tce_tables which exists only with CONFIG_PPC_BOOK3S_64. However these modules are selected when COMPILE_TEST and SPAPR_TCE_IOMMU are chosen leading to build failures: In file included from arch/powerpc/include/asm/book3s/64/mmu-hash.h:20:0, from arch/powerpc/kvm/book3s_64_vio_hv.c:22: arch/powerpc/include/asm/book3s/64/pgtable.h:17:0: error: "_PAGE_EXEC" redefined [-Werror] #define _PAGE_EXEC 0x00001 /* execute permission */ In file included from arch/powerpc/include/asm/book3s/32/pgtable.h:8:0, from arch/powerpc/include/asm/book3s/pgtable.h:8, from arch/powerpc/include/asm/pgtable.h:18, from include/linux/mm.h:95, from arch/powerpc/include/asm/io.h:29, from include/linux/io.h:13, from include/linux/irq.h:20, from arch/powerpc/include/asm/hardirq.h:6, from include/linux/hardirq.h:9, from include/linux/kvm_host.h:7, from arch/powerpc/kvm/book3s_64_vio_hv.c:12: arch/powerpc/include/asm/book3s/32/hash.h:29:0: note: this is the location of the previous definition #define _PAGE_EXEC 0x200 /* software: exec allowed */ Fixes: e93a1695d7fb ("iommu: Enable compile testing for some of drivers") Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200414142630.21153-1-krzk@kernel.org Signed-off-by: Joerg Roedel <jroedel@suse.de>
2020-04-29iommu/mediatek: Fix MTK_IOMMU dependenciesGeert Uytterhoeven1-1/+1
If NO_DMA=y (e.g. Sun-3 all{mod,yes}-config): drivers/iommu/dma-iommu.o: In function `iommu_dma_mmap': dma-iommu.c:(.text+0x836): undefined reference to `dma_pgprot' IOMMU_DMA must not be selected, unless HAS_DMA=y. Hence fix this by making MTK_IOMMU depend on HAS_DMA. While at it, remove the dependency on ARM || ARM64, as that is already implied by the dependency on ARCH_MEDIATEK.
