SYNOPSIS

       struct platform_nand_ctrl {
	 int (* probe) (struct platform_device *pdev);
	 void (* remove) (struct platform_device *pdev);
	 void (* hwcontrol) (struct mtd_info *mtd, int cmd);

	 unsigned char (* read_byte) (struct mtd_info *mtd);
	 void * priv;
       };

MEMBERS

       probe
	   platform specific function to probe/setup hardware

       remove
	   platform specific function to remove/teardown hardware

       hwcontrol
	   platform specific hardware control structure

       dev_ready
	   platform specific function to read ready/busy pin

       select_chip
	   platform specific chip select function

       cmd_ctrl
	   platform specific function for controlling ALE/CLE/nCE. Also used to write command and address

       write_buf
	   platform specific function for write buffer

       read_buf
	   platform specific function for read buffer

       read_byte
	   platform specific function to read one byte from chip

       priv

STRUCT 
IRQ_DATA(9)						    Structures							STRUCT IRQ_DATA(9)

NAME

       struct_irq_data - per irq and irq chip data passed down to chip functions

SYNOPSIS

       struct irq_data {
	 unsigned int irq;
	 unsigned long hwirq;
	 unsigned int node;
	 unsigned int state_use_accessors;
	 struct irq_chip * chip;
	 struct irq_domain * domain;
	 void * handler_data;
	 void * chip_data;
	 struct msi_desc * msi_desc;
	 cpumask_var_t affinity;
       };

MEMBERS

       irq
	   interrupt number

       hwirq
	   hardware interrupt number, local to the interrupt domain

       node
	   node index useful for balancing

       state_use_accessors
	   status information for irq chip functions. Use accessor functions to deal with it

       chip
	   low level interrupt hardware access

       domain
	   Interrupt translation domain; responsible for mapping between hwirq number and linux irq number.

       handler_data
	   per-IRQ data for the irq_chip methods

       chip_data
	   platform-specific per-chip private data for the chip methods, to allow shared chip implementations

       msi_desc
	   MSI descriptor

       affinity
	   IRQ affinity on SMP

DESCRIPTION

       The fields here need to overlay the ones in irq_desc until we cleaned up the direct references and switched everything over to irq_data.
