      irqchip: sirf: move from legacy mode to linear irqdomain · 29eb51a7
      Barry Song 提交于
      the series of patches for irqdomain core in 3.11 has broken sirf
      irq which uses legacy mapping. all users fail in the new kernel
      while setupping irq.
      
      this patch moves to linear irqdomain and drop old legacy irqdomain
      codes since we don't need it any more, and at the same time, it
      also fixes the broken interrupts of sirfsoc in 3.11.
      
      on the other hand, we actually only have 64 interrupt sources for
      prima2 and atlas6, but there are 128 interrupt souces for marco
      which uses GIC. in the legacy codes, sirf gpio also uses legacy
      irqdomain, so to make gpio interrupt mapping not depend on the
      prima2/atlas6/marco an use unified marco,we enlarge prima2/atlas6
      interrupt number to 128. here we don't need this workaround any
      more as sirf gpio also moved to linear mode before. so we move
      SIRFSOC_NUM_IRQS back to 64 too.

      ARM: tegra: always enable USB VBUS regulators · 30ca2226
      Stephen Warren 提交于
      This fixes a regression exposed during the merge window by commit
      9f310ded "ARM: tegra: fix VBUS regulator GPIO polarity in DT"; namely that
      USB VBUS doesn't get turned on, so USB devices are not detected. This
      affects the internal USB port on TrimSlice (i.e. the USB->SATA bridge, to
      which the SSD is connected) and the external port(s) on Seaboard/
      Springbank and Whistler.
      
      The Tegra DT as written in v3.11 allows two paths to enable USB VBUS:
      
      1) Via the legacy DT binding for the USB controller; it can directly
         acquire a VBUS GPIO and activate it.
      
      2) Via a regulator for VBUS, which is referenced by the new DT binding
         for the USB controller.
      
      Those two methods both use the same GPIO, and hence whichever of the
      USB controller and regulator gets probed first ends up owning the GPIO.
      In practice, the USB driver only supports path (1) above, since the
      patches to support the new USB binding are not present until v3.12:-(
      
      In practice, the regulator ends up being probed first and owning the
      GPIO. Since nothing enables the regulator (the USB driver code is not
      yet present), the regulator ends up being turned off. This originally
      caused no problem, because the polarity in the regulator definition was
      incorrect, so attempting to turn off the regulator actually turned it
      on, and everything worked:-(
      
      However, when testing the new USB driver code in v3.12, I noticed the
      incorrect polarity and fixed it in commit 9f310ded "ARM: tegra: fix VBUS
      regulator GPIO polarity in DT". In the context of v3.11, this patch then
      caused the USB VBUS to actually turn off, which broke USB ports with VBUS
      control. I got this patch included in v3.11-rc1 since it fixed a bug in
      device tree (incorrect polarity specification), and hence was suitable to
      be included early in the rc series. I evidently did not test the patch at
      all, or correctly, in the context of v3.11, and hence did not notice the
      issue that I have explained above:-(
      
      Fix this by making the USB VBUS regulators always enabled. This way, if
      the regulator owns the GPIO, it will always be turned on, even if there
      is no USB driver code to request the regulator be turned on. Even
      ignoring this bug, this is a reasonable way to configure the HW anyway.
      
      If this patch is applied to v3.11, it will cause a couple pretty trivial
      conflicts in tegra20-{trimslice,seaboard}.dts when creating v3.12, since
      the context right above the added lines changed in patches destined for
      v3.12.

      Register target address to be used for cpgmac is the second device

      With removal of address space from hwmod and using DT instead, cpgmac

      ARM: OMAP2+: hwmod: rt address space index for DT · 130142d9
      Afzal Mohammed 提交于
      Address space is being removed from hwmod database and DT information
      in <reg> property is being used. Currently the 0th index of device
      address space is used to map for register target address. This is not
      always true, eg. cpgmac has it's sysconfig in second address space.
      
      Handle it by specifying index of device address space to be used for
      register target. As default value of this field would be zero with
      static initialization, existing behaviour of using first address space
      for register target while using DT would be kept as such.

      ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL · 7dedd346
      Rajendra Nayak 提交于
      With commit '82702ea1' "ARM: OMAP2+:
      Fix serial init for device tree based booting" stubbing out
      omap_serial_early_init() for Device tree based booting, there was a
      crash observed on AM335x based devices when hwmod does a
      _setup_reset() early at boot.
      
      This was rootcaused to hwmod trying to reset console uart while
      earlycon was using it.  The way to tell hwmod not to do this is to
      specify the HWMOD_INIT_NO_RESET flag, which were infact set by the
      omap_serial_early_init() function by parsing the cmdline to identify
      the console device.
      
      Parsing the cmdline to identify the uart used by earlycon itself seems
      broken as there is nothing preventing earlycon to use a different one.
      
      This patch, instead, attempts to populate the requiste flags for hwmod
      based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need
      for cmdline parsing in the DT as well as non-DT cases to identify the
      uart used by earlycon.

      commit e00c27ef
      (ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)

      The following optional/unused regulators can be updated:
      
      - SMPS9 supplies TWL6040 over VDDA_2v1_AUD. This regulator needs to be
      enabled only when audio is active. Since it does not come active by
      default, it does not require "always-on" or "boot-on".
      
      - LDO2 and LDO8 do not go to any peripheral or connector on the board.
      Further, these unused regulators should have been 2.8V for LDO2 and
      3.0V for LDO8. Mark these LDOs as disabled in the dts until needed.

      ARM: dts: omap5-uevm: fix regulator configurations mandatory for SoC · e18235a6
      Nishanth Menon 提交于
      commit e00c27ef
      (ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
      introduced regulator entries for OMAP5uEVM.
      
      However, The regulator information is based on an older temporary
      pre-production board variant and does not reflect production board
      750-2628-XXX boards.
      
      The following fixes are hence mandatory to ensure right voltage is
      supplied to key OMAP5 SoC voltage rails:
      
      - LDO1 supplies VDDAPHY_CAM which is OMAP5's vdda_csiporta/b/c. This
      can only be supplied at 1.5V or 1.8V and we currently supply 2.8V.
      
      To prevent any potential device damage risk, use the specified
      1.5V-1.8V supply.
      
      Remove 'always-on' and 'boot-on' settings here as it is
      a 'on need' supply to SoC IP and is not enabled by PMIC by
      default at boot.
      
      - LDO3 supplies Low Latency Interface(LLI) hardware module which is a
      special hardware to communicate with Modem. However since uEVM is
      not setup by default for this communication, this should be disabled
      by default.
      
      Further, vdda_lli is supposed to be 1.5V and not 3V.
      
      - LDO4 supplies VDDAPHY_DISP which is vdda_dsiporta/c/vdda_hdmi
      
      This can only be supplied at 1.5V or 1.8V and we currently
      supply 2.2V.
      
      To prevent any potential device damage risk, use the specified
      1.5V-1.8V supply.
      
      Remove 'always-on' and 'boot-on' settings here as it is a 'on need'
      supply to SoC IP and is not enabled by PMIC by default at boot.
      
      - LDO6 supplies the board specified VDDS_1V2_WKUP supply going to
      ldo_emu_wkup/vdds_hsic. To stay within the SoC specification supply
      1.2V instead of 1.5V.
      
      - LDO7 supplies VDD_VPP which is vpp1. This is currently configured for
      1.5V which as per data manual "A pulse width of 1000 ns and an amplitude
      of 2V is required to program each eFuse bit. Otherwise, VPP1 must not
      be supplied".
      
      So, fix the voltage to 2V. and disable the supply since we have no plans
      of programming efuse bits - it can only be done once - in factory.
      
      Further it is not enabled by default by PMIC so, 'boot-on' must be
      removed, and the 'always-on' needs to be removed to achieve pulsing
      if efuse needs to be programmed.
      
      - LDO9 supplies the board specified vdds_sdcard supply going within SoC
      specification of 1.8V or 3.0V. Further the supply is controlled by
      switch enabled by REGEN3. So, introduce REGEN3 and map sdcard slot to
      be powered by LDO9. Remove 'always-on' allowing the LDO to be disabled
      on need basis.

        a sleeping while atomic warning.
      
        The other two patches are the big ugly ones that redo how the driver
        allocates objects and reserves them and makes things all work
        properly, I've tested this in a VM, and compared to the current code
        which hits a lockdep warning and the sleep while atomic warning before
        failing.
      
        So sorry this is coming in late, I should have tested qxl before
        merging the mutex code, but I'd rather just fix qxl with this than
        revert the reservations code at this point"
      
      * 'qxl-fixes' of git://people.freedesktop.org/~airlied/linux:
        qxl: convert qxl driver to proper use for reservations
        qxl: allow creation of pre-pinned objects and use for releases.
        drm/qxl: add delayed fb operations

      Pull ACPI and power management fixes from Rafael Wysocki:
       "These are just two fixes, a revert of the would-be backlight fix that
        didn't work and an intel_pstate fix for two problems related to
        maximum P-state selection.
      
        Specifics:
      
         - Revert of the ACPI video commit that I hoped would help fix
           backlight problems related to Windows 8 compatibility on some
           systems.  Unfortunately, it turned out to cause problems to happen
           too.
      
         - Fix for two problems in intel_pstate, a possible failure to respond
           to a load change on a quiet system and a possible failure to select
           the highest available P-state on some systems.  From Dirk
           Brandewie"
