2022-07-21spi: spi-rspi: Fix PIO fallback on RZ platformsBiju Das1-0/+4
RSPI IP on RZ/{A, G2L} SoC's has the same signal for both interrupt and DMA transfer request. Setting DMARS register for DMA transfer makes the signal to work as a DMA transfer request signal and subsequent interrupt requests to the interrupt controller are masked. PIO fallback does not work as interrupt signal is disabled. This patch fixes this issue by re-enabling the interrupts by calling dmaengine_synchronize().

transfers In case a IRQ based transfer times out the bcm2835_spi_handle_err() function is called. Since commit 1513ceee70f2 ("spi: bcm2835: Drop dma_pending flag") the TX and RX DMA transfers are unconditionally canceled, leading to NULL pointer derefs if ctlr->dma_tx or ctlr->dma_rx are not set.

2022-07-20mlxsw: spectrum_router: Fix IPv4 nexthop gateway indicationIdo Schimmel1-1/+1
mlxsw needs to distinguish nexthops with a gateway from connected nexthops in order to write the former to the adjacency table of the device. The check used to rely on the fact that nexthops with a gateway have a 'link' scope whereas connected nexthops have a 'host' scope. This is no longer correct after commit 747c14307214 ("ip: fix dflt addr selection for connected nexthop"). Fix that by instead checking the address family of the gateway IP. This is a more direct way and also consistent with the IPv6 counterpart in mlxsw_sp_rt6_is_gateway().

2022-07-19drm/i915/guc: support v69 in parallel to v70Daniele Ceraolo Spurio7-62/+417
This patch re-introduces support for GuC v69 in parallel to v70. As this is a quick fix, v69 has been re-introduced as the single "fallback" guc version in case v70 is not available on disk and only for platforms that are out of force_probe and require the GuC by default. All v69 specific code has been labeled as such for easy identification, and the same was done for all v70 functions for which there is a separate v69 version, to avoid accidentally calling the wrong version via the unlabeled name. When the fallback mode kicks in, a drm_notice message is printed in dmesg to inform the user of the required update. The existing logging of the fetch function has also been updated so that we no longer complain immediately if we can't find a fw and we only throw an error if the fetch of both the base and fallback blobs fails. The plan is to follow this up with a more complex rework to allow for multiple different GuC versions to be supported at the same time. v2: reduce the fallback to platform that require it, switch to firmware_request_nowarn(), improve logs.

2022-07-19drm/i915/guc: Support programming the EU priority in the GuC descriptorMatthew Brost3-11/+33
In GuC submission mode the EU priority must be updated by the GuC rather than the driver as the GuC owns the programming of the context descriptor. Given that the GuC code uses the GuC priorities, we can't use a generic function using i915 priorities for both execlists and GuC submission. The existing function has therefore been pushed to the execlists back-end while a new one has been added for GuC. v2: correctly use the GuC prio.

Przemyslaw fixes handling of multiple VLAN requests to account for individual errors instead of rejecting them all. He removes incorrect implementations of ETHTOOL_COALESCE_MAX_FRAMES and ETHTOOL_COALESCE_MAX_FRAMES_IRQ. He also corrects an issue with NULL pointer caused by improper handling of dummy receive descriptors.

This fixes that the platform is waked by an unexpected packet. The size and range of FIFO is different when the device enters S3 state, so it is necessary to correct some settings when suspending. Regardless of jumbo frame, set RMS to 1522 and MTPS to MTPS_DEFAULT. Besides, enable MCU_BORW_EN to update the method of calculating the pointer of data.

2022-07-19amt: use workqueue for gateway side message handlingTaehee Yoo1-15/+144
There are some synchronization issues(amt->status, amt->req_cnt, etc) if the interface is in gateway mode because gateway message handlers are processed concurrently. This applies a work queue for processing these messages instead of expanding the locking context. So, the purposes of this patch are to fix exist race conditions and to make gateway to be able to validate a gateway status more correctly. When the AMT gateway interface is created, it tries to establish to relay. The establishment step looks stateless, but it should be managed well. In order to handle messages in the gateway, it saves the current status(i.e. AMT_STATUS_XXX). This patch makes gateway code to be worked with a single thread. Now, all messages except the multicast are triggered(received or delay expired), and these messages will be stored in the event queue(amt->events). Then, the single worker processes stored messages asynchronously one by one. The multicast data message type will be still processed immediately. Now, amt->lock is only needed to access the event queue(amt->events) if an interface is the gateway mode.

We meet issue on PCA9557PW on i.MX8QXP/DXL evk board, this device do not support AI mode, but when do the regmap sync, regmap will sync 3 byte data to register 1, logically this means write first data to register 1, write second data to register 2, write third data to register 3. But this device do not support AI mode, finally, these three data write only into register 1 one by one. the reault is the value of register 1 alway equal to the latest data, here is the third data, no operation happened on register 2 and register 3.
