| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than marking the mach/gpio.h header files which want to use the trivial GPIOLIB implementation, mark those which do not want to use it instead. This means that by default, you get the trivial implementation and only have to do something extra if you need to. This should encourage the use of the trivial default implementation. As an additional bonus, several gpio.h header files become empty.

Unfortunately the OF binding added in c519ecf2 ("ARM: 7009/1: l2x0: Add OF based initialization") does not represent the interrupt. This patch adds an "interrupts" property to the L2x0 OF binding, representing the combined interrupt line.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | using cpu_relax in busy loops is a well-known idiom in the kernel. It's more for documentation purposes than technically needed here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds probing for ARM L2x0 cache controllers via device tree. Support includes the L210, L220, and PL310 controllers. The binding allows setting up cache RAM latencies and filter addresses (PL310 only).
