   4 Subject: [PATCH 162/196] bcm2708: select NEED_MACH_GPIO_H
   5
   6 makers out there use to use gpio_to_irq() in board setup code. it is
   7 necessary that gpio_to_irq() be defined as a macro for this to work.
   8
   9 https://github.com/raspberrypi/linux/commit/01464226ac6089bd6a33f9899cc792c2355ebf39,
  10 on its way towards devicetree, introduces a switch NEED_MACH_GPIO_H
  11 that platforms have to set to get the macro definition of
  12 gpio_to_irq() - otherwise, the gpiolib incarnation of gpio_to_irq() is
  13 found instead which does not work from board code.
  14
  15 define NEED_MACH_GPIO_H to make things work again without any pain for
  16 makers (though this clearly is in the way of devicetree).
