      x86: mrst: Set vRTC's IRQ to level trigger type · 6f207e9b
      Feng Tang 提交于
      When setting up the mpc_intsrc structure for vRTC's IRQ,
      we need to set its irqflag to level trigger, otherwise
      it will be taken as edge triggered and the vRTC IRQ will
      fire only once, as there is never a EOI issued from the
      IA core for it.
      
      The original code worked in previous kernel. This is  because it
      was configured to level trigger type by luck. It fell
      into the default PCI trigger category which is level triggered.

      x86: mrst: Parse SFI timer table for all timer configs · 7f05dec3
      Jacob Pan 提交于
      Penwell has APB timer based watchdog timers, it requires platform code to parse
      SFI MTMR tables in order to claim its timer.
      
      This patch will always parse SFI MTMR regardless of system timer configuration
      choices. Otherwise, SFI MTMR table may not get parsed if running on Medfield
      with always-on local APIC timers and constant TSC. Watchdog timer driver will
      then not get a timer to use.

      x86/mrst: Add SFI platform device parsing code · 1da4b1c6
      Feng Tang 提交于
      SFI provides a series of tables. These describe the platform devices present
      including SPI and I²C devices, as well as various sensors, keypads and other
      glue as well as interfaces provided via the SCU IPC mechanism (intel_scu_ipc.c)
      
      This patch is a merge of the core elements and relevant fixes from the
      Intel development code by Feng, Alek, myself into a single coherent patch
      for upstream submission.
      
      It provides the needed infrastructure to register I2C, SPI and platform devices
      described by the tables, as well as handlers for some of the hardware already
      supported in kernel. The 0.8 firmware also provides GPIO tables.
      
      Devices are created at boot time or if they are SCU dependant at the point an
      SCU is discovered. The existing Linux device mechanisms will then handle the
      device binding. At an abstract level this is an SFI to Linux device translator.
      
      Device/platform specific setup/glue is in this file. This is done so that the
      drivers for the generic I²C and SPI bus devices remain cross platform as they
      should.
      
      (Updated from RFC version to correct the emc1403 name used by the firmware
       and a wrongly used #define)
