From b8842451079a3034363320b932205d9cea791e9d Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 3 Feb 2009 12:30:26 -0700 Subject: powerpc/5200: Trim cruft from device trees Trim out obsolete/extraneous properties and tighten up some usage conventions. Changes include: - removal of device_type properties - removal of cell-index properties - Addition of gpio-controller and #gpio-cells properties to gpio nodes - Move common interrupt-parent property out of device nodes and into top level parent node. This patch also include what looks to be just trivial editorial whitespace/format changes, but there is real method in this madness. Editorial changes were made to keep the all the mpc5200 board device trees as similar as possible so that diffs between them only show the real differences between the boards. The pcm030 device tree was most affected by this because many of the comments had been changed from // to /* */ style and some cell values where changed from decimal to hex format when it was cloned from one of the other 5200 device trees.

With this patch the mpc5200-gpt driver supports both GPIO and IRQ functions. The GPT driver was contained within the mpc52xx_gpio.c file, but this patch moves it out into a new file (mpc52xx_gpt.c) since it has more than just GPIO functionality now and it was only grouped with the mpc52xx-gpio drivers as a matter of convenience before. Also, this driver will most likely get extended again to also provide support for the timer function. Implementation note: Alternately, I could have tried to implement the IRQ support as a separate driver and left the GPIO portion alone. However, multiple functions of this device (ie. GPIO input+interrupt controller, or timer+GPIO) can be active at the same time and the registers are shared so it is safer to contain all functionality within a single driver.

Changes are: - add the media5200 device tree - add the media5200 platform support code and cascaded interrupt controller - add media5200 to the build targets. Note: this patch also includes a minor tweak to the lite5200(b) target images list to add the .dtb files to the image list.
