      bus: ti-sysc: Flush posted write on enable and disable · 5ce8aee8
      Tony Lindgren authored
      Looks like we're missing flush of posted write after module enable and
      disable. I've seen occasional errors accessing various modules, and it
      is suspected that the lack of posted writes can also cause random reboots.
      
      The errors we can see are similar to the one below from spi for example:
      
      44000000.ocp:L3 Custom Error: MASTER MPU TARGET L4CFG (Read): Data Access
      in User mode during Functional access
      ...
      mcspi_wait_for_reg_bit
      omap2_mcspi_transfer_one
      spi_transfer_one_message
      ...
      
      We also want to also flush posted write for disable. The clkctrl clock
      disable happens after module disable, and we don't want to have the
      module potentially stay active while we're trying to disable the clock.

      ARM: dts: Fix wrong mdio clock for dm814x · fb6823a6
      Tony Lindgren authored
      Recent PTP-specific cpsw driver changes started exposing an issue on at
      at least j5eco-evm:
      
      Unhandled fault: external abort on non-linefetch (0x1008) at 0xf0169004

      Let's fix the issue by using the correct mdio clock as suggested by
      Grygorii Strashko <grygorii.strashko@ti.com>.
      
      The DM814_ETHERNET_CPGMAC0_CLKCTRL clock is the interconnect target module
      clock and managed by ti-sysc.

      ARM: dts: am437x: fix networking on boards with ksz9031 phy · 2de00450
      Grygorii Strashko authored
      Since commit bcf3440c ("net: phy: micrel: add phy-mode support for the
      KSZ9031 PHY") the networking is broken on boards:
       am437x-gp-evm
       am437x-sk-evm
       am437x-idk-evm
      
      All above boards have phy-mode = "rgmii" and this is worked before, because
      KSZ9031 PHY started with default RGMII internal delays configuration (TX
      off, RX on 1.2 ns) and MAC provided TX delay. After above commit, the
      KSZ9031 PHY starts handling phy mode properly and disables RX delay, as
      result networking is become broken.
      
      Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous
      behavior.

      ARM: dts: omap4-droid4: Fix occasional lost wakeirq for uart1 · 738b150e
      Tony Lindgren authored
      Looks like using the UART CTS pin does not always trigger for a wake-up
      when the SoC is idle.
      
      This is probably because the modem first uses gpio_149 to signal the SoC
      that data will be sent, and the CTS will only get used later when the
      data transfer is starting.
      
      Let's fix the issue by configuring the gpio_149 pad as the wakeirq for
      UART. We have gpio_149 managed by the USB PHY for powering up the right
      USB mode, and after that, the gpio gets recycled as the modem wake-up
      pin. If needeed, the USB PHY can also later on be configured to use
      gpio_149 pad as the wakeirq as a shared irq.
      
      Let's also configure the missing properties for uart-has-rtscts and
      current-speed for the modem port while at it. We already configure the
      hardware flow control pins with uart1_pins pinctrl setting.

      ARM: dts: omap4-droid4: Fix flakey wlan by disabling internal pull for gpio · 30fa60c6
      Tony Lindgren authored
      The wlan on droid4 is flakey on some devices, and experiments have shown this
      gets fixed if we disable the internal pull for wlan gpio interrupt line.
      
      The symptoms are that the wlan connection is very slow and almost useless
      with lots of wlcore firmware reboot warnings in the dmesg.
      
      In addition to configuring the wlan gpio pulls, let's also configure the rest
      of the wlan sd pins. We have not configured those eariler as we're booting
      using kexec.

      MAINTAINERS: sort field names for all entries · 3b50142d
      Linus Torvalds authored
      This sorts the actual field names too, potentially causing even more
      chaos and confusion at merge time if you have edited the MAINTAINERS
      file.  But the end result is a more consistent layout, and hopefully
      it's a one-time pain minimized by doing this just before the -rc1
      release.
      
      This was entirely scripted:
      
        ./scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS --order

      MAINTAINERS: sort entries by entry name · 4400b7d6
      Linus Torvalds authored
      They are all supposed to be sorted, but people who add new entries don't
      always know the alphabet.  Plus sometimes the entry names get edited,
      and people don't then re-order the entry.
      
      Let's see how painful this will be for merging purposes (the MAINTAINERS
      file is often edited in various different trees), but Joe claims there's
      relatively few patches in -next that touch this, and doing it just
      before -rc1 is likely the best time.  Fingers crossed.
      
      This was scripted with
      
        /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS
      
      but then I also ended up manually upper-casing a few entry names that
      stood out when looking at the end result.

        Add proper sanity checks which prevent the unconditional injection
        into the guest and handles the #AC on the host side in the same way as
        user space detections are handled. Depending on the detection mode it
