From b298322b7576c9d5750fdc7d3e588ec9238af1d3 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Thu, 12 Apr 2012 11:45:08 +0200 Subject: ARM: pxa: use ioremap to access CPLD The pcm990 baseboard for the pcm027 module used to setup a static mapping for accessing the CPLD. It became illegal to call iotable_init that late. The pcm027 support is broken since then. This patch switches the cpld support to ioremap and removes all references to previous static mappings.

Although pxa2xx_transceiver_mode() can subsequently set these two signals via its own call to pxa2xx_mfp_config(), pxa2xx_transceiver_mode() is only present when CONFIG_PXA_FICP=y. Hence this patch provides a default mfp config.

Change GPIO23_SSP1_SCLK value in hx4700_pin_config[] from an output to an input, since the NavPoint is connected to SSP in SPI slave mode. 2. Add GPIO102_GPIO (NavPoint power) to hx4700_pin_config[]. 3. Add navpoint platform_device to devices[].
