From 924a158a12c7e732179dd85ddd20848039e7bd71 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 26 Apr 2009 13:14:52 +0100 Subject: [ARM] Convert pmd_page() to be highmem safe In the long run, we may want to place page tables in highmem. However, pmd_page() has traditionally been coded to convert the physical address to a virtual one, which won't work with highmem pages. Instead, translate the physical address to a PFN, and then convert the PFN to a struct page instead.

This removes the dependency on and properly reports the memory addresses used by the driver in /proc/iomem. In addition, ep93xx_rtc_init() is updated to use platform_driver_probe() instead of platform_driver_register(). Also, the device_create_file() calls are now properly checked for error conditions. The created sysfs files are also now removed when the driver is removed. The version number for the driver has been bumped at the request of Alessandro Zummo.

GPIO and PADMUX support This adds GPIO and PADMUX headers and implementation for the U300 platform. This is an implementation in isolation that depend on later patches in this series to plug into the framework.

Supports memory mappings, interrupt controller, system timer (clocksource and clockevents), and binds to the existing drivers for the PrimeCells used in this design: PL190 (VIC), PL180 (MMC/SD host) and PL011 (UART). This is intented to serve as starting point for our mainling work, more patches to follow.

This lead to some kind of difficulties to read this file and maintainability issues as the number of AT91 cpus & PLLs/clocks is growing. In this patch, I try to group clock functionality together and match cpus with this functionality set.
