* 'davinci-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-davinci: (48 commits)
  Revert "rtc: omap: let device wakeup capability be configured from chip init logic"
  DM365: Added more PINMUX configurations for AEMIF
  DM365: Make CLKOUTx available
  DM365: Added PINMUX definitions for GPIO30..32
  Davinci: iotable based ioremap() interception
  Davinci: pinmux - use ioremap()
  Davinci: aintc/cpintc - use ioremap()
  Davinci: psc - use ioremap()
  Davinci: timer - use ioremap()
  Davinci: jtag_id - use ioremap()
  Davinci: da8xx: rtc - use ioremap
  Davinci: gpio - use ioremap()
  davinci: edma: fix coding style issue related to breaking lines
  davinci: edma: use BIT() wherever possible
  davinci: edma: fix coding style issue related to usage of braces
  davinci: edma: use a more intuitive name for edma_info
  Davinci: serial - conditional reset via pwremu
  Davinci: serial - use ioremap()
  Davinci: serial - remove unnecessary define
  Davinci: watchdog reset separation across socs

If you say yes here you get support for the RTC on the
DaVinci platforms (DM365).
This driver can also be built as a module. If so, the module
will be called rtc-davinci.
