2017-06-29tty: serial: lpuart: introduce lpuart_soc_data to represent SoC propertyDong Aisheng1-20/+27
This is used to dynamically check the SoC specific lpuart properies. Currently only the iotype is added, it functions the same as before. With this, new chips with different iotype will be more easily added.

2017-06-29serial: imx-serial - move DMA buffer configuration to DTNandor Han2-8/+19
The size of the DMA buffer can affect the delta time between data being produced and data being consumed. Basically the DMA system will move data to tty buffer when a) DMA buffer is full b) serial line is idle. The situation is visible when producer generates data continuously and there is no possibility for idle line. At this point the DMA buffer is directly affecting the delta time. The patch will add the possibility to configure the DMA buffers in DT, which case by case can be configured separately for every driver instance. The DT configuration is optional and in case missing the driver will use the 4096 buffer with 4 periods (as before), therefore no clients are impacted by this change.

2017-06-29serial: 8250: 8250_omap: Fix race b/w dma completion and RX timeoutVignesh R1-2/+21
DMA RX completion handler for UART is called from a tasklet and hence may be delayed depending on the system load. In meanwhile, there may be RX timeout interrupt which can get serviced first before DMA RX completion handler is executed for the completed transfer. omap_8250_rx_dma_flush() which is called on RX timeout interrupt makes sure that the DMA RX buffer is pushed and then the FIFO is drained and also queues a new DMA request. But, when DMA RX completion handler executes, it will erroneously flush the currently queued DMA transfer which sometimes results in data corruption and double queueing of DMA RX requests. Fix this by checking whether RX completion is for the currently queued transfer or not. And also hold port lock when in DMA completion to avoid race wrt RX timeout handler preempting it.

2017-06-29serial: 8250: Fix THRE flag usage for CAP_MINIPhil Elwell1-0/+4
The BCM2835 MINI UART has non-standard THRE semantics. Conventionally the bit means that the FIFO is empty (although there may still be a byte in the transmit register), but on 2835 it indicates that the FIFO is not full. This causes interrupts after every byte is transmitted, with the FIFO providing some interrupt latency tolerance. A consequence of this difference is that the usual strategy of writing multiple bytes into the TX FIFO after checking THRE once is unsafe. In the worst case of 7 bytes in the FIFO, writing 8 bytes loses all but the first since by then the FIFO is full. There is an HFIFO ("Hidden FIFO") capability that causes the transmit loop to terminate when both THRE and TEMT are set, i.e. when the TX block is completely idle. This is unnecessarily cautious, potentially causing gaps in transmission. Add a new conditional to the transmit loop, predicated on CAP_MINI, that exits when THRE is no longer set (the FIFO is full). This allows the FIFO to fill quickly but subsequent writes are paced by the transmission rate.

Remove the broken alt_speed code, and warn when trying to set the line speed using TIOCSSERIAL and SPD flags.

Also remove the verbose and outdated comment on how to set baud rates.

2017-06-09tty: add TIOCGPTPEER ioctlAleksa Sarai9-5/+76
When opening the slave end of a PTY, it is not possible for userspace to safely ensure that /dev/pts/$num is actually a slave (in cases where the mount namespace in which devpts was mounted is controlled by an untrusted process). In addition, there are several unresolvable race conditions if userspace were to attempt to detect attacks through stat(2) and other similar methods [in addition it is not clear how userspace could detect attacks involving FUSE]. Resolve this by providing an interface for userpace to safely open the "peer" end of a PTY file descriptor by using the dentry cached by devpts. Since it is not possible to have an open master PTY without having its slave exposed in /dev/pts this interface is safe. This interface currently does not provide a way to get the master pty (since it is not clear whether such an interface is safe or even useful).

That caused files to be truncated on UFS-2 file systems because the default maximum file size is 2GB (MAX_NON_LFS) and UFS didn't update it.

2017-06-03nfs: Mark unnecessarily extern functions as staticJan Kara2-4/+3
nfs_initialise_sb() and nfs_clone_super() are declared as extern even though they are used only in fs/nfs/super.c. Mark them as static. Also remove explicit 'inline' directive from nfs_initialise_sb() and leave it upto compiler to decide whether inlining is worth it.

2017-06-03hwmon: (aspeed-pwm-tacho) make fan/pwm names start with index 1Stefan Schaeckeler1-26/+26
Make fan and pwm names in sysfs start with index 1 in accordance to Documentation/hwmon/sysfs-interface conventions. Current implementation starts with index 0, making tools such as sensors(1) skip the first fan.
