2015-06-03Add TI CDCE925 I2C controlled clock synthesizer driverMike Looijmans
This driver supports the TI CDCE925 programmable clock synthesizer. The chip contains two PLLs with spread-spectrum clocking support and five output dividers. The driver only supports the following setup, and uses a fixed setting for the output muxes: Y1 is derived from the input clock Y2 and Y3 derive from PLL1 Y4 and Y5 derive from PLL2 Given a target output frequency, the driver will set the PLL and divider to best approximate the desired output.

2015-05-15Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"Brian Norris
In commit 8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation.

2015-05-10pty: Fix input race when closingPeter Hurley
A read() from a pty master may mistakenly indicate EOF (errno == -EIO) after the pty slave has closed, even though input data remains to be read. For example, pty slave | input worker | pty master | | | | n_tty_read() pty_write() | | input avail? no add data | | sleep schedule worker --->| | . |---> flush_to_ldisc() | . pty_close() | fill read buffer | . wait for worker | wakeup reader --->| . | read buffer full? |---> input avail ? yes |<--- yes - exit worker | copy 4096 bytes to user TTY_OTHER_CLOSED <---| |<--- kick worker | | **** New read() before worker starts **** | | n_tty_read() | | input avail? no | | TTY_OTHER_CLOSED? yes | | return -EIO Several conditions are required to trigger this race: 1. the ldisc read buffer must become full so the input worker exits 2. the read() count parameter must be >= 4096 so the ldisc read buffer is empty 3. the subsequent read() occurs before the kicked worker has processed more input However, the underlying cause of the race is that data is pipelined, while tty state is not; ie., data already written by the pty slave end is not yet visible to the pty master end, but state changes by the pty slave end are visible to the pty master end immediately. Pipeline the TTY_OTHER_CLOSED state through input worker to the reader. 1. Introduce TTY_OTHER_DONE which is set by the input worker when TTY_OTHER_CLOSED is set and either the input buffers are flushed or input processing has completed. Readers/polls are woken when TTY_OTHER_DONE is set. 2. Reader/poll checks TTY_OTHER_DONE instead of TTY_OTHER_CLOSED. 3. A new input worker is started from pty_close() after setting TTY_OTHER_CLOSED, which ensures the TTY_OTHER_DONE state will be set if the last input worker is already finished (or just about to exit). Remove tty_flush_to_ldisc(); no in-tree callers.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Arnd Bergmann: "A few patches have come up since the merge window. The largest one is a rewrite of the PXA lubbock/mainstone IRQ handling. This was already broken in 2011 by a change to the GPIO code and only noticed now. The other changes contained here are: MAINTAINERS file updates: - Ray Jui and Scott Branden are now co-maintainers for some of the mach-bcm chips, while Christian Daudt and Marc Carino have stepped down. - Andrew Victor is no longer maintaining at91. Instead, Alexandre Belloni now becomes an official maintainer, after having done a bulk of the work for a while. - Baruch Siach, who added the mach-digicolor platform in 4.1 is now listed as maintainer - The git URL for mach-socfpga has changed Bug fixes: - Three bug fixes for new rockchip rk3288 code - A regression fix to make SD card support work on certain ux500 boards - multiple smaller dts fixes for imx, omap, mvebu, and shmobile - a regression fiix for omap3 power consumption - a fix for regression in the ARM CCI bus driver Configuration changes: - more imx platforms are now enabled in multi_v7_defconfig" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits) MAINTAINERS: add Conexant Digicolor machines entry MAINTAINERS: socfpga: update the git repo for SoCFPGA ARM: multi_v7_defconfig: Select more FSL SoCs MAINTAINERS: replace an AT91 maintainer drivers: CCI: fix used_mask init in validate_group() bus: omap_l3_noc: Fix master id address decoding for OMAP5 bus: omap_l3_noc: Fix offset for DRA7 CLK1_HOST_CLK1_2 instance ARM: dts: dra7: Fix efuse register size for ABB ARM: dts: am57xx-beagle-x15: Switch GPIO fan number ARM: dts: am57xx-beagle-x15: Switch UART mux pins ARM: dts: am437x-sk: reduce col-scan-delay-us ARM: dts: am437x-sk: fix for new newhaven display module revision ARM: dts: am57xx-beagle-x15: Fix RTC aliases ARM: dts: am57xx-beagle-x15: Fix IRQ type for mcp7941x ARM: dts: omap3: Add #iommu-cells to isp and iva iommu ARM: omap2plus_defconfig: Enable EXTCON_USB_GPIO ARM: dts: OMAP3-N900: Add microphone bias voltages ARM: OMAP2+: Fix omap off idle power consumption creeping up MAINTAINERS: Update brcmstb entry MAINTAINERS: Remove Christian Daudt for mach-bcm ...

Since the introduction of clk-si5351 the way we should deal with DT provided clocks has changed from indexed to named clock phandles. Amend the binding documentation to reflect named clock phandles by clock-names property.
