   * AB8500 register access
   * ======================
   *
   * read:
   * # echo BANK  >  <debugfs>/ab8500/register-bank
   * # echo ADDR  >  <debugfs>/ab8500/register-address
   * # cat <debugfs>/ab8500/register-value

   * # echo BANK  >  <debugfs>/ab8500/register-bank
   * # echo ADDR  >  <debugfs>/ab8500/register-address
   * # echo VALUE >  <debugfs>/ab8500/register-value
   *
   * read all registers from a bank:
   * # echo BANK  >  <debugfs>/ab8500/register-bank
   * # cat <debugfs>/ab8500/all-bank-register
   *
   * BANK   target AB8500 register bank
   * ADDR   target AB8500 register address
   * VALUE  decimal or 0x-prefixed hexadecimal
   *
   *
   * 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.
