2020-07-21soundwire: intel: add wake interrupt supportRander Wang
When system is suspended in clock stop mode on intel platforms, both master and slave are in clock stop mode and soundwire bus is taken over by a glue hardware. The bus message for jack event is processed by this glue hardware, which will trigger an interrupt to resume audio pci device. Then audio pci driver will resume soundwire master and slave, transfer bus ownership to master, finally slave will report jack event to master and codec driver is triggered to check jack status. if a slave has been attached to a bus, the slave->dev_num_sticky should be non-zero, so we can check this value to skip the ghost devices defined in ACPI table but not populated in hardware.

2020-07-21soundwire: intel/cadence: merge Soundwire interrupt handlers/threadsBard Liao
The existing code uses one pair of interrupt handler/thread per link but at the hardware level the interrupt is shared. This works fine for legacy PCI interrupts, but leads to timeouts in MSI (Message-Signaled Interrupt) mode, likely due to edges being lost. This patch unifies interrupt handling for all links. The dedicated handler is removed since we use a common one for all shared interrupt sources, and the thread function takes care of dealing with interrupt sources. This partition follows the model used for the SOF IPC on HDaudio platforms, where similar timeout issues were noticed and doing all the interrupt handling/clearing in the thread improved reliability/stability. Validation results with 4 links active in parallel show a night-and-day improvement with no timeouts noticed even during stress tests. Latency and quality of service are not affected by the change - mostly because events on a SoundWire link are throttled by the bus frame rate (typically 8..48kHz).

Make sure all symbols in this soundwire-intel-init module are exported with a namespace. The MODULE_IMPORT_NS will be used in Intel/SOF HDaudio modules to be posted in a separate series. Namespaces are only introduced for the Intel parts of the SoundWire code at this time, in future patches we should also add namespaces for Cadence parts and the SoundWire core.

2020-07-21soundwire: intel: revisit SHIM programming sequences.Pierre-Louis Bossart
Somehow the existing code is not aligned with the steps described in the documentation, refactor code and make sure the register programming sequences are correct. Also add missing power-up, power-down and wake capabilities (the last two are used in follow-up patches but introduced here for consistency). Some of the SHIM registers exposed fields that are link specific, and in addition some of the power-related registers (SPA/CPA) take time to be updated. Uncontrolled access leads to timeouts or errors. Add a mutex, shared by all links, so that all accesses to such registers are serialized, and follow a pattern of read-modify-write. This includes making sure SHIM_SYNC is programmed only once, before the first master is powered on. We use a 'shim_mask' field, shared between all links and protected by a mutex, to deal with power-up and power-down sequences. Note that the SYNCPRD value is tied only to the XTAL value and not the current bus frequency or the frame rate.

The current memory allocation is somewhat strange: the dma_data is allocated in set_sdw_stream, but released in the intel DAI shutdown. This no longer works with the multi-cpu implementation, since the dma_data is released in the dai shutdown which takes place before the dailink shutdown. Move to a more symmetric allocation where the dma_data is allocated with non-NULL SoundWire stream, and conversely released when a NULL stream is provided - for consistency with the stream startup and shutdown operations.

2020-06-22soundwire: intel: transition to 3 steps initializationPierre-Louis Bossart
Rather than a plain-vanilla init/exit, this patch provides 3 steps in the initialization needed for driver selection, machine driver selection and deal with power rail dependencies. - ACPI scan: this step is done at a very early stage to detect the presence of a SoundWire Controller and enabled links at the BIOS level. This step may be called from the legacy HDaudio driver, which will abort its probe to let the Sound Open Firmware (SOF) handle the hardware. - probe: this step allocates all the required memory and will add a sdw_bus, which in turn will result in identifying all possible Slaves listed below the Controller ACPI companion device. All the information is reported to the parent PCI driver which will select the relevant machine driver. - startup: this last step starts the bus reset, which results in Slave devices reporting as ATTACHED and being enumerated. This step is only done during the card creation stage, after the DSP is powered to account for internal power rail dependencies. These 3 steps are already supported in the Sound Open firmware drivers and upstream.

2020-06-14Revert "btrfs: switch to iomap_dio_rw() for dio"David Sterba
This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option.

2020-06-13net: ethernet: ti: ale: fix allmulti for nu type aleGrygorii Strashko
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
