They are known - * as comm1 and comm2 (communication areas 1 and 2). Comm1 is for - * input, and comm2 is for output. Each is controlled by three - * registers: BASE (base address), CFG (config) and CCTL - * (config/control). - * - * Each DMA channel points to a physically contiguous ring buffer in - * main memory of up to 8 Kbytes. (This driver always uses 8 Kb.) - * There are three pointers into the ring buffer: read, write, and - * trigger. The pointers are 8 bits each. Each pointer points to - * 32-byte "chunks" of data. The DMA engine moves 32 bytes at a time, - * so there is no finer-granularity control. - * - * In comm1, the hardware updates the write ptr, and software updates - * the read ptr. In comm2, it's the opposite: hardware updates the - * read ptr, and software updates the write ptr. I designate the - * hardware-updated ptr as the hwptr, and the software-updated ptr as - * the swptr. - * - * The trigger ptr and trigger mask are used to trigger interrupts. - * From the Lithium spec, section 5.6.8, revision of 12/15/1998: - * - * Trigger Mask Value - * - * A three bit wide field that represents a power of two mask - * that is used whenever the trigger pointer is compared to its - * respective read or write pointer. A value of zero here - * implies a mask of 0xFF and a value of seven implies a mask - * 0x01. This value can be used to sub-divide the ring buffer - * into pie sections so that interrupts monitor the progress of - * hardware from section to section. - * - * My interpretation of that is, whenever the hw ptr is updated, it is - * compared with the trigger ptr, and the result is masked by the - * trigger mask. (Actually, by the complement of the trigger mask.) - * If the result is zero, an interrupt is triggered. I.e., interrupt - * if ((hwptr & ~mask) == (trptr & ~mask)). The mask is formed from - * the trigger register value as mask = (1 << (8 - tmreg)) - 1. - * - * In yet different words, setting tmreg to 0 causes an interrupt after - * every 256 DMA chunks (8192 bytes) or once per traversal of the - * ring buffer. Setting it to 7 caues an interrupt every 2 DMA chunks - * (64 bytes) or 128 times per traversal of the ring buffer. - */ - -/* Lithium register offsets and bit definitions */ - -#define LI_HOST_CONTROLLER 0x000 -# define LI_HC_RESET 0x00008000 -# define LI_HC_LINK_ENABLE 0x00004000 -# define LI_HC_LINK_FAILURE 0x00000004 -# define LI_HC_LINK_CODEC 0x00000002 -# define LI_HC_LINK_READY 0x00000001 - -#define LI_INTR_STATUS 0x010 -#define LI_INTR_MASK 0x014 -# define LI_INTR_LINK_ERR 0x00008000 -# define LI_INTR_COMM2_TRIG 0x00000008 -# define LI_INTR_COMM2_UNDERFLOW 0x00000004 -# define LI_INTR_COMM1_TRIG 0x00000002 -# define LI_INTR_COMM1_OVERFLOW 0x00000001 - -#define LI_CODEC_COMMAND 0x018 -# define LI_CC_BUSY 0x00008000 -# define LI_CC_DIR 0x00000080 -# define LI_CC_DIR_RD LI_CC_DIR -# define LI_CC_DIR_WR (!LI_CC_DIR) -# define LI_CC_ADDR_MASK 0x0000007F - -#define LI_CODEC_DATA 0x01C - -#define LI_COMM1_BASE 0x100 -#define LI_COMM1_CTL 0x104 -# define LI_CCTL_RESET 0x80000000 -# define LI_CCTL_SIZE 0x70000000 -# define LI_CCTL_DMA_ENABLE 0x08000000 -# define LI_CCTL_TMASK 0x07000000 /* trigger mask */ -# define LI_CCTL_TPTR 0x00FF0000 /* trigger pointer */ -# define LI_CCTL_RPTR 0x0000FF00 -# define LI_CCTL_WPTR 0x000000FF -#define LI_COMM1_CFG 0x108 -# define LI_CCFG_LOCK 0x00008000 -# define LI_CCFG_SLOT 0x00000070 -# define LI_CCFG_DIRECTION 0x00000008 -# define LI_CCFG_DIR_IN (!LI_CCFG_DIRECTION) -# define LI_CCFG_DIR_OUT LI_CCFG_DIRECTION -# define LI_CCFG_MODE 0x00000004 -# define LI_CCFG_MODE_MONO (!LI_CCFG_MODE) -# define LI_CCFG_MODE_STEREO LI_CCFG_MODE -# define LI_CCFG_FORMAT 0x00000003 -# define LI_CCFG_FMT_8BIT 0x00000000 -# define LI_CCFG_FMT_16BIT 0x00000001 -#define LI_COMM2_BASE 0x10C -#define LI_COMM2_CTL 0x110 - /* bit definitions are the same as LI_COMM1_CTL */ -#define LI_COMM2_CFG 0x114 - /* bit definitions are the same as LI_COMM1_CFG */ - -#define LI_UST_LOW 0x200 /* 64-bit Unadjusted System Time is */ -#define LI_UST_HIGH 0x204 /* microseconds since boot */ - -#define LI_AUDIO1_UST 0x300 /* UST-MSC pairs */ -#define LI_AUDIO1_MSC 0x304 /* MSC (Media Stream Counter) */ -#define LI_AUDIO2_UST 0x308 /* counts samples actually */ -#define LI_AUDIO2_MSC 0x30C /* processed as of time UST */ - -/* - * Lithium's DMA engine operates on chunks of 32 bytes.
