      mfd: lpc_ich: Fix a 3.5 kernel regression for iTCO_wdt driver · 092369ef
      Feng Tang authored
      There are many reports (including 2 of my machines) that iTCO_wdt watchdog
      driver fails to be initialized in 3.5 kernel with error message like:
      
      [    5.265175] ACPI Warning: 0x00001060-0x0000107f SystemIO conflicts with Region \_SB_.PCI0.LPCB.TCOI 1 (20120320/utaddress-251)
      [    5.265192] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
      [    5.265206] lpc_ich: Resource conflict(s) found affecting iTCO_wdt
      
      The root cause the iTCO_wdt driver in 3.4 probes the HW IO resource from
      LPC's PCI config space, while in 3.5 kernel it relies on lpc_ich driver
      for the probe, which adds a new acpi_check_resource_conflict() check, and
      give up the probe if there is any conflict with ACPI.
      
      Fix it by removing all the checks for iTCO_wdt to keep the same behavior as
      3.4 kernel.
      https://bugzilla.kernel.org/show_bug.cgi?id=44991
      
      Actually the same check could be removed for the gpio-ich in lpc_ich.c,
      but I'm not sure if it will cause problems.

      mfd: Move tps65217 regulator plat data handling to regulator · 817bb7fb
      AnilKumar Ch authored
      Regulator platform data handling was mistakenly added to MFD
      driver. So we will see build errors if we compile MFD drivers
      without CONFIG_REGULATOR. This patch moves regulator platform
      data handling from TPS65217 MFD driver to regulator driver.
      
      This makes MFD driver independent of REGULATOR framework so
      build error is fixed if CONFIG_REGULATOR is not set.
      
      drivers/built-in.o: In function `tps65217_probe':
      tps65217.c:(.devinit.text+0x13e37): undefined reference
      to `of_regulator_match'
      
      This patch also fix allocation size of tps65217 platform data.
      Current implementation allocates a struct tps65217_board for each
      regulator specified in the device tree. But the structure itself
      provides array of regulators so one instance of it is sufficient.
