+ * AB8500 register access
+ * ======================

+ * # 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.
