From 691de57679e3f05b708b98ca2ab27657c768843f Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Tue, 21 Oct 2008 08:58:44 +0000 Subject: powerpc: Remove device_type = "rtc" properties in .dts files We don't want to encourage the device_type usage. It isn't used in the code, so we can simply remove it from the dts files.

This patch adds basic support for the GPIO in the devices I/O FPGA, the GPIO functionality is exposed through the AFIX pins on the backplane, unless used by an AFIX card. This code currently does not support switching between totem-pole and open-drain outputs (when used as outputs, GPIOs default to totem-pole). The interrupt capabilites of the GPIO lines is also not currently supported.

MPIC is shared between two cores but each core will protect its interrupts from other core by using "protected-sources" of mpic.

The patch includes changes to the Bamboo and Canyonlands device-trees to add such a hole, others can be updated separately. The ISA memory hole is an additional outbound window configured in the bridge to generate PCI cycles in the low memory addresses, thus allowing to access things such as the hard-decoded VGA aperture at 0xa0000..0xbffff or other similar things. It's made accessible to userspace via the new legacy_mem file in sysfs for which support was added by a previous patch.

There is a known cache coherency issue with the L2 cache, but this is related to the high bandwidth (HB) PLB segment where the memory address is 0x8.xxxx.xxxx (low bandwidth PLB segment is mapped to 0x0.xxxx.xxxx). Since this HB address is currently unused it is safe to enable the L2 cache.

So far all devices are detected as OF device. A notifier function is used to set the dma_ops for the of_platform bus.
