This patch removes old platform devices. Alsa should now be using the ASoC driver. For boards not yet using ASoC, please see sound/soc/omap/osk5912.c. Add dummy aic23_power_up and aic23_power_down functions for 770 to keep things compiling. Remove references to omap_gpio_switch, and unused h2_nand_dev_ready function. This patch is based on an earlier patch by Arun KS. Cc: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Arun KS <arunks@mistralsolutions.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
