Detailed Description

struct d40_base - The big global struct, one for each probe'd instance.

: Lock used to make sure one interrupt is handle a time. : Lock for execute command usage since several channels share the same physical register. : The device structure. : The virtual base address of the DMA's register. : silicon revision detected. : Pointer to the DMA clock structure. : Physical memory start of the DMA registers. : Size of the DMA register map. : The IRQ number. : The number of physical channels. Read from HW. This is the number of available channels for this driver, not counting "Secure mode" allocated physical channels. : The number of logical channels. Calculated from num_phy_chans. : dma_device channels that can do both memcpy and slave transfers. : dma_device channels that can do only do slave transfers. : dma_device channels that can do only do memcpy transfers. : Room for all possible physical channels in system. : Room for all possible logical channels in system. : Used to map interrupt number to logical channel. Points to log_chans entries. : Used to map interrupt number to physical channel. Points to phy_chans entries. : Pointer to provided platform_data which is the driver configuration. : Pointer to hold the regulator for the esram bank for lcla. : Vector containing all physical channels. : lcla pool settings and data. : The virtual mapped address of LCPA. : The physical address of the LCPA. : The size of the LCPA area. : cache for descriptors. : Here the values of some hardware registers are stored before the DMA is powered off. They are restored when the power is back on. : Backup of registers that only exits on dma40 v3 and later. : Backup data for standard channel parameter registers. : Mask to maintain the channels that can be turned off. : true if the dma has been initialized
