      I2C/ACPI: Clean up I2C ACPI code and Add CONFIG_I2C_ACPI config · da3c6647
      Lan Tianyu authored
      Clean up ACPI related code in the i2c core and add CONFIG_I2C_ACPI
      to enable I2C ACPI code.
      
      Current there is a race between removing I2C ACPI operation region
      and ACPI AML code accessing. So make i2c core built-in if CONFIG_I2C_ACPI
      is set.

      I2C/ACPI: Add i2c ACPI operation region support · 5d98e61d
      Lan Tianyu authored
      ACPI 5.0 spec(5.5.2.4.5) defines GenericSerialBus(i2c, spi, uart) operation region.
      It allows ACPI aml code able to access such kind of devices to implement
      some ACPI standard method.
      
      ACPI Spec defines some access attribute to associate with i2c protocol.
      AttribQuick 	       	       		Read/Write Quick Protocol
      AttribSendReceive			Send/Receive Byte Protocol
      AttribByte 			 	Read/Write Byte Protocol
      AttribWord				Read/Write Word Protocol
      AttribBlock				Read/Write Block Protocol
      AttribBytes				Read/Write N-Bytes Protocol
      AttribProcessCall			Process Call Protocol
      AttribBlockProcessCall			Write Block-Read Block Process Call Protocol
      AttribRawBytes 				Raw Read/Write N-BytesProtocol
      AttribRawProcessBytes			Raw Process Call Protocol
      
      On the Asus T100TA, Bios use GenericSerialBus operation region to access
      i2c device to get battery info.
      
      Sample code From Asus T100TA
      
          Scope (_SB.I2C1)
          {
              Name (UMPC, ResourceTemplate ()
              {
                  I2cSerialBus (0x0066, ControllerInitiated, 0x00061A80,
                      AddressingMode7Bit, "\\_SB.I2C1",
                      0x00, ResourceConsumer, ,
                      )
              })
      
      	...
      
              OperationRegion (DVUM, GenericSerialBus, Zero, 0x0100)
              Field (DVUM, BufferAcc, NoLock, Preserve)
              {
                  Connection (UMPC),
                  Offset (0x81),
                  AccessAs (BufferAcc, AttribBytes (0x3E)),
                  FGC0,   8
              }
      	...
           }
      
           Device (BATC)
           {
               Name (_HID, EisaId ("PNP0C0A"))  // _HID: Hardware ID
               Name (_UID, One)  // _UID: Unique ID
      	 ...
      
                  Method (_BST, 0, NotSerialized)  // _BST: Battery Status
                  {
                      If (LEqual (AVBL, One))
                      {
                          Store (FGC0, BFFG)
                          If (LNotEqual (STAT, One))
                          {
                              ShiftRight (CHST, 0x04, Local0)
                              And (Local0, 0x03, Local0)
                              If (LOr (LEqual (Local0, One), LEqual (Local0, 0x02)))
                              {
                                  Store (0x02, Local1)
                              }
      	...
      
          }
      
      The i2c operation region is defined under I2C1 scope. _BST method under
      battery device BATC read battery status from the field "FCG0". The request
      would be sent to i2c operation region handler.
      
      This patch is to add i2c ACPI operation region support. Due to there are
      only "Byte" and "Bytes" protocol access on the Asus T100TA, other protocols
      have not been tested.
      
      About RawBytes and RawProcessBytes protocol, they needs specific drivers to interpret
      reference data from AML code according ACPI 5.0 SPEC(5.5.2.4.5.3.9 and 5.5.2.4.5.3.10).
      So far, not found such case and will add when find real case.

      Pull i2c new drivers from Wolfram Sang:
       "Here is a pull request from i2c hoping for the "new driver" rule.
      
        Originally, I wanted to send this request during the merge window, but
        code checkers with very recent additions complained, so a few fixups
        were needed.  So, some more time went by and I merged rc1 to get a
        stable base"
      
      So the "new driver" rule is really about drivers that people absolutely
      need for the kernel to work on new hardware, which is not so much the
      case for i2c.  So I considered not pulling this, but eventually
      relented.
      
      Just for FYI: the whole (and only) point of "new drivers" is not that
      new drivers cannot regress things (they can, and they have - by
      triggering badly tested code on machines that never triggered that code
      before), but because they can bring to life machines that otherwise
      wouldn't be useful at all without the drivers.
      
      So the new driver rule is for essential things that actual consumers
      would care about, ie devices like networking or disk drivers that matter
      to normal people (not server people - they run old kernels anyway, so
      mainlining new drivers is irrelevant for them).

      Pull ACPI and power management fixes from Rafael Wysocki:
       "These are fixes mostly (ia64 regression related to the ACPI
        enumeration of devices, cpufreq regressions, fix for I2C controllers
        included in Intel SoCs, mvebu cpuidle driver fix related to sysfs)
        plus additional kernel command line arguments from Kees to make it
        possible to build kernel images with hibernation and the kernel
        address space randomization included simultaneously, a new ACPI
        battery driver quirk for a system with a broken BIOS and a couple of
        ACPI core cleanups.
      
        Specifics:
      
         - Fix for an ia64 regression introduced during the 3.11 cycle by a
           commit that modified the hardware initialization ordering and made
           device discovery fail on some systems.
      
         - Fix for a build problem on systems where the cpufreq-cpu0 driver is
           built-in and the cpu-thermal driver is modular from Arnd Bergmann.
      
         - Fix for a recently introduced computational mistake in the
           intel_pstate driver that leads to excessive rounding errors from
           Doug Smythies.
      
         - Fix for a failure code path in cpufreq_update_policy() that fails
           to unlock the locks acquired previously from Aaron Plattner.
      
         - Fix for the cpuidle mvebu driver to use shorter state names which
           will prevent the sysfs interface from returning mangled strings.
           From Gregory Clement.
      
         - ACPI LPSS driver fix to make sure that the I2C controllers included
           in BayTrail SoCs are not held in the reset state while they are
           being probed from Mika Westerberg.
      
         - New kernel command line arguments making it possible to build
           kernel images with hibernation and kASLR included at the same time
           and to select which of them will be used via the command line (they
           are still functionally mutually exclusive, though).  From Kees
           Cook.
      
         - ACPI battery driver quirk for Acer Aspire V5-573G that fails to
           send battery status change notifications timely from Alexander
           Mezin.
      
         - Two ACPI core cleanups from Christoph Jaeger and Fabian Frederick"

         - Fixes for races in the wait/wakeup logic used in blk-mq from
           Alexander.  No issues have been observed, but it is definitely a
           bit flakey currently.  Alternatively, we may drop the cyclic
           wakeups going forward, but that needs more testing.
      
         - Some cleanups from Christoph.
      
         - Fix for an oops in null_blk if queue_mode=1 and softirq completions
           are used.  From me.
      
         - A fix for a regression caused by the chunk size setting.  It
           inadvertently used max_hw_sectors instead of max_sectors, which is
           incorrect, and causes hangs on btrfs multi-disk setups (where hw
           sectors apparently isn't set).  From me.
      
         - Removal of WQ_POWER_EFFICIENT in the kblockd creation.  This was a
           recent addition as well, but it actually breaks blk-mq which relies
           on strict scheduling.  If the workqueue power_efficient mode is
           turned on, this breaks blk-mq.  From Matias.

      unicore32: Remove ARCH_HAS_CPUFREQ config option · d670878e
      Stephen Boyd authored
      This config exists entirely to hide the cpufreq menu from the
      kernel configuration unless a platform has selected it. Nothing
      is actually built if this config is 'Y' and it just leads to more
      patches that add a select under a platform Kconfig so that some
      other CPUfreq option can be chosen. Let's remove the option so
      that we can always enable CPUfreq drivers on unicore32 platforms.

      drivers: scsi: mvsas: fix compiling issue by adding 'MVS_' for "enum pci_interrupt_cause" · 8902b107
      Chen Gang authored
      The direct cause is IRQ_SPI is already defined as a macro in unicore32
      architecture (also, blackfin and mips architectures define it). The
      related error (unicore32  with allmodconfig)
      
          CC [M]  drivers/scsi/mvsas/mv_94xx.o
        In file included from drivers/scsi/mvsas/mv_94xx.c:27:
        drivers/scsi/mvsas/mv_94xx.h:176: error: expected identifier before numeric constant
      
      And IRQ_SAS_A and IRQ_SAS_B are used as 'u32' (although "enum
      pci_interrupt_cause" is not used directly, now).
      
      All together, need add 'MVS_' for "enum pci_interrupt_cause".

      After check the code, 'bswapsi2' and 'muldi3' are useless for
      unicore32, so can remove them to avoid compiling failure.
