The WM9712 with which this driver - * was developped with always sends GPIO status data in slot 12 which - * we receive in our (PCM-) data stream. The only chance we have is to - * manually skip this data in the FIQ handler. With sampling rates different - * from 48000Hz not every frame has valid receive data, so the ratio - * between pcm data and GPIO status data changes. Our FIQ handler is not - * able to handle this, hence this driver only works with 48000Hz sampling - * rate. - * Reading and writing AC97 registers is another challenge. The core - * provides us status bits when the read register is updated with *another* - * value. When we read the same register two times (and the register still - * contains the same value) these status bits are not set. We work - * around this by not polling these bits but only wait a fixed delay. - * - */ - -#include <linux/clk.h> -#include <linux/delay.h> -#include <linux/device.h> -#include <linux/dma-mapping.h> -#include <linux/init.h> -#include <linux/interrupt.h> -#include <linux/module.h> -#include <linux/platform_device.h> -#include <linux/slab.h> -
