* User Space notification on AB8500 IRQ
|
|
|
|
* =====================================
|
|
|
|
*
|
|
|
|
* Allows user space entity to be notified when target AB8500 IRQ occurs.
|
|
|
|
* When subscribed, a sysfs entry is created in ab8500.i2c platform device.
|
|
|
|
* One can pool this file to get target IRQ occurence information.
|
|
|
|
*
|
|
|
|
* subscribe to an AB8500 IRQ:
|
|
|
|
* # echo IRQ > <debugfs>/ab8500/irq-subscribe
|
|
|
|
*
|
|
|
|
* unsubscribe from an AB8500 IRQ:
|
|
|
|
* # echo IRQ > <debugfs>/ab8500/irq-unsubscribe
|
|
|
|
*
|
|
|
|
*
|
|
|
|
* AB8500 register formated read/write access
|
|
|
|
* ==========================================
|
|
|
|
*
|
|
|
|
* Read: read data, data>>SHIFT, data&=MASK, output data
|
|
|
|
* [0xABCDEF98] shift=12 mask=0xFFF => 0x00000CDE
|
|
|
|
* Write: read data, data &= ~(MASK<<SHIFT), data |= (VALUE<<SHIFT), write data
|
|
|
|
* [0xABCDEF98] shift=12 mask=0xFFF value=0x123 => [0xAB123F98]
|
|
|
|
*
|
|
|
|
* Usage:
|
|
|
|
* # echo "CMD [OPTIONS] BANK ADRESS [VALUE]" > $debugfs/ab8500/hwreg
|
|
|
|
*
|
|
|
|
* CMD read read access
|

|
|
* write write access
|
|
|
|
*
|
|
|
|
* BANK target reg bank
|
|
|
|
* ADDRESS target reg address
|
|
|
|
* VALUE (write) value to be updated
|
|
|
|
*
|
|
|
|
* OPTIONS
|
|
|
|
* -d|-dec (read) output in decimal
|
|
|
|
* -h|-hexa (read) output in 0x-hexa (default)
|
|
|
|
* -l|-w|-b 32bit (default), 16bit or 8bit reg access
|
|
|
|
* -m|-mask MASK 0x-hexa mask (default 0xFFFFFFFF)
|
|
|
|
* -s|-shift SHIFT bit shift value (read:left, write:right)
|
|
|
|
* -o|-offset OFFSET address offset to add to ADDRESS value
|
|
|
|
*
|
|
|
|
* Warning: bit shift operation is applied to bit-mask.
|
|
|
|
* Warning: bit shift direction depends on read or right command.
