2019-12-25spi: uniphier: Add DMA transfer mode supportKunihiko Hayashi1-2/+198
This adds DMA transfer mode support for UniPhier SPI controller. Since this controller requires simulteaneous transmission and reception, this indicates SPI_CONTROLLER_MUST_RX and SPI_CONTROLLER_MUST_TX. Because the supported dma controller has alignment restiction, there is also a restriction that 'maxburst' parameters in dma_slave_config corresponds to one word width.

2019-12-25spi: uniphier: Fix FIFO thresholdKunihiko Hayashi1-12/+19
Rx threshold means the value to inform the receiver when the number of words in Rx FIFO is equal to or more than the value. Similarly, Tx threshold means the value to inform the sender when the number of words in Tx FIFO is equal to or less than the value. The controller triggers the driver to start the transfer. In case of Rx, the driver wants to detect that the specified number of words N are in Rx FIFO, so the value of Rx threshold should be N. In case of Tx, the driver wants to detect that the same number of spaces as Rx are in Tx FIFO, so the value of Tx threshold should be (FIFO size - N). For example, in order for the driver to receive at least 3 words from Rx FIFO, set 3 to Rx threshold. +-+-+-+-+-+-+-+-+ | | | | | |*|*|*| +-+-+-+-+-+-+-+-+ In order for the driver to send at least 3 words to Tx FIFO, because it needs at least 3 spaces, set 8(FIFO size) - 3 = 5 to Tx threshold. +-+-+-+-+-+-+-+-+ |*|*|*|*|*| | | | +-+-+-+-+-+-+-+-+ This adds new function uniphier_spi_set_fifo_threshold() to set threshold value to the register. And more, FIFO counts by 'words', so this renames 'fill_bytes' with 'fill_words', and fixes the calculation using bytes_per_words.

2019-12-09spi: bitbang: Make chipselect callback optionalLinus Walleij1-2/+19
The ->chipselect() callback on the bit-banged SPI library master is optional if using GPIO descriptors: when using descriptors exclusively without any native chipselects, the core does not even call out the the native ->set_cs() and therefore ->chipselect() on a bit-banged SPI master will not even be called in this case. Make sure to respect the SPI_MASTER_GPIO_SS as used by e.g. spi-gpio.c though: this setting will make the core handle the chip select using GPIO descriptors *AND* call the local chipselect handler.

Orangefs has no open, and orangefs checks file permissions on each file access. Posix requires that file permissions be checked on open and nowhere else. Orangefs-through-the-kernel needs to seem posix compliant. The VFS opens files, even if the filesystem provides no method. We can see if a file was successfully opened for read and or for write by looking at file->f_mode. When writes are flowing from the page cache, file is no longer available. We can trust the VFS to have checked file->f_mode before writing to the page cache. The mode of a file might change between when it is opened and IO commences, or it might be created with an arbitrary mode. We'll make sure we don't hit EACCES during the IO stage by using UID 0" [ This is "posixish", but not a great solution in the long run, since a proper secure network server shouldn't really trust the client like this. But proper and secure POSIX behavior requires an open method and a resulting cookie for IO of some kind, or similar. - Linus ] * tag 'for-linus-5.5-ofs1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux: orangefs: posix open permission checking...

2019-12-08pipe: don't use 'pipe_wait() for basic pipe IOLinus Torvalds1-3/+27
pipe_wait() may be simple, but since it relies on the pipe lock, it means that we have to do the wakeup while holding the lock. That's unfortunate, because the very first thing the waked entity will want to do is to get the pipe lock for itself. So get rid of the pipe_wait() usage by simply releasing the pipe lock, doing the wakeup (if required) and then using wait_event_interruptible() to wait on the right condition instead. wait_event_interruptible() handles races on its own by comparing the wakeup condition before and after adding itself to the wait queue, so you can use an optimistic unlocked condition for it.
