From 6c3a158316598bfb165b8c83b168fa413d5ae2d8 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 17 Aug 2007 16:55:22 +0100 Subject: [ARM] 4550/1: sched_clock on PXA should cope with run time clock rate selection The previous implementation was relying on compile time optimizations based on a constant clock rate. However, support for different PXA flavors in the same kernel binary requires that the clock be selected at run time, so here it is. Let's move this code to a more appropriate location while at it.

GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types.
