4 Subject: [PATCH 162/174] 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).
