2017-01-31spi: mediatek: Only do dma for 4-byte aligned buffersDaniel Kurtz
Mediatek SPI DMA only works when tx and rx buffer addresses are 4-byte aligned. Unaligned DMA transactions appeared to work previously, since we the spi core was incorrectly using the spi_master device for dma, which had a 0 dma_mask, and therefore the swiotlb dma map operations were falling back to using bounce buffers. Since each DMA transaction would use its own buffer, the mapped starting address of each transaction was always aligned. When doing real DMA, the mapped address will share the alignment of the raw tx/rx buffer provided by the SPI user, which may or may not be aligned. If a buffer is not aligned, we cannot use DMA, and must use FIFO based transaction instead. So, this patch implements a scheme that allows using the FIFO for arbitrary length transactions (larger than the 32-byte FIFO size) by reloading the FIFO in the interrupt handler.

2017-01-31spi: When no dma_chan map buffers with spi_master's parentDaniel Kurtz
Back before commit 1dccb598df54 ("arm64: simplify dma_get_ops"), for arm64, devices for which dma_ops were not explicitly set were automatically configured to use swiotlb_dma_ops, since this was hard-coded as the global "dma_ops" in arm64_dma_init(). Now that global "dma_ops" has been removed, all devices much have their dma_ops explicitly set by a call to arch_setup_dma_ops(), otherwise the device is assigned dummy_dma_ops, and thus calls to map_sg for such a device will fail (return 0). Mediatek SPI uses DMA but does not use a dma channel. Support for this was added by commit c37f45b5f1cd ("spi: support spi without dma channel to use can_dma()"), which uses the master_spi dev to DMA map buffers. The master_spi device is not a platform device, rather it is created in spi_alloc_device(), and therefore its dma_ops are never set. Therefore, when the mediatek SPI driver when it does DMA (for large SPI transactions > 32 bytes), SPI will use spi_map_buf()->dma_map_sg() to map the buffer for use in DMA. But dma_map_sg()->dma_map_sg_attrs() returns 0, because ops->map_sg is dummy_dma_ops->__dummy_map_sg, and hence spi_map_buf() returns -ENOMEM (-12). Fix this by using the real spi_master's parent device which should be a real physical device with DMA properties.

So far were were allocating struct bgmac in 3 places: platform code, bcma code and shared bgmac_enet_probe function. The reason for this was bgmac_enet_probe: 1) Requiring early-filled struct bgmac 2) Calling alloc_etherdev on its own in order to use netdev_priv later This solution got few drawbacks: 1) Was duplicating allocating code 2) Required copying early-filled struct 3) Resulted in platform/bcma code having access only to unused struct Solve this situation by simply extracting some probe code into the new bgmac_alloc function.

The SCSI passthrough idea was a a bad idea to start with (guess who came up with it?), and has been removed from the virtio 1.O spec, and is not enabled by defauly by any host I know of. Add a separate config option for it so that we don't need to enable it for most setups.

2017-01-31ACPI / button: Change default behavior to lid_init_state=openLv Zheng
More and more platforms need the button.lid_init_state=open quirk. This patch sets it the default behavior. If a platform doesn't send lid open event or lid open event is lost due to the underlying system problems, then we can compare various combinations: 1. systemd/acpid is used to suspend system or not, systemd has a special logic forcing open event after resuming; 2. _LID returns a cached value or not. The result is as follows: 1. lid_init_state=method 1. cached 1. resumed by lid: (x) event=close (x) systemd=suspends again (x) acpid=suspends again (x) state=close 2. resumed by other: (o) event=close (x) systemd=suspends again (x) acpid=suspends again (o) state=close 2. non-cached 1. resumed by lid: (o) event=open (o) systemd=resumes (o) acpid=resumes (o) state=open 2. resumed by other: (o) event=close (x) systemd=suspends again (x) acpid=suspends again (o) state=close 2. lid_init_state=open 1. cached 1. resumed by lid: (o) event=open (o) systemd=resumes (o) acpid=resumes (x) state=close 2. resumed by other: (x) event=open (o) systemd=resumes (o) acpid=resumes (o) state=close 2. non-cached 1. resumed by lid: (o) event=open (o) systemd=resumes (o) acpid=resumes (o) state=open 2. resumed by other: (x) event=open (o) systemd=resumes (o) acpid=resumes (o) state=close 3. lid_init_state=ignore 1. cached 1. resumed by lid: (o) event=none (x) systemd=suspends again (o) acpid=resumes (x) state=close 2. resumed by other: (o) event=none (x) systemd=suspends again (o) acpid=resumes (o) state=close 2. non-cached 1. resumed by lid: (o) event=none (x) systemd=suspends again (o) acpid=resumes (o) state=open 2. resumed by other: (o) event=none (x) systemd=suspends again (o) acpid=resumes (o) state=close As a conclusion: 1. With systemd changed, lid_init_state=ignore has only one problem and the problem comes from an underlying issue, not userspace and kernel lid handling. 2. Without systemd changed, lid_init_state=open can be the default behavior as the pass ratio is not much worse than lid_init_state=ignore. 3. lid_init_state=method is buggy, we can have a separate patch to make it deprectated.

2017-01-31lightnvm: allow targets to use sysfsJavier González
In order to register through the sysfs interface, a driver needs to know its kobject. On a disk structure, this happens when the partition information is added (device_add_disk), which for lightnvm takes place after the target has been initialized. This means that on target initialization, the kboject has not been created yet. This patch adds a target function to let targets initialize their own kboject as a child of the disk kobject.
