| 8 | * AB8500 register access |
| 9 | * ====================== |
| 10 | * |
| 11 | * read: |

| 13 | * # echo ADDR > <debugfs>/ab8500/register-address |
| 14 | * # cat <debugfs>/ab8500/register-value |

| 17 | * # echo BANK > <debugfs>/ab8500/register-bank |
| 18 | * # echo ADDR > <debugfs>/ab8500/register-address |
| 19 | * # echo VALUE > <debugfs>/ab8500/register-value |
| 20 | * |
| 21 | * read all registers from a bank: |
| 22 | * # echo BANK > <debugfs>/ab8500/register-bank |
| 23 | * # cat <debugfs>/ab8500/all-bank-register |
| 24 | * |
| 25 | * BANK target AB8500 register bank |
| 26 | * ADDR target AB8500 register address |
| 27 | * VALUE decimal or 0x-prefixed hexadecimal |
| 28 | * |
| 29 | * |
| 30 | * User Space notification on AB8500 IRQ |
| 31 | * ===================================== |
| 32 | * |
| 33 | * Allows user space entity to be notified when target AB8500 IRQ occurs. |
| 34 | * When subscribed, a sysfs entry is created in ab8500.i2c platform device. |
| 35 | * One can pool this file to get target IRQ occurence information. |
| 36 | * |
| 37 | * subscribe to an AB8500 IRQ: |
| 38 | * # echo IRQ > <debugfs>/ab8500/irq-subscribe |
| 39 | * |
| 40 | * unsubscribe from an AB8500 IRQ: |
| 41 | * # echo IRQ > <debugfs>/ab8500/irq-unsubscribe |
| 42 | * |
| 43 | * |
| 44 | * AB8500 register formated read/write access |
| 45 | * ========================================== |
| 46 | * |
| 47 | * Read: read data, data>>SHIFT, data&=MASK, output data |
| 48 | * [0xABCDEF98] shift=12 mask=0xFFF => 0x00000CDE |
| 49 | * Write: read data, data &= ~(MASK<<SHIFT), data |= (VALUE<<SHIFT), write data |
| 50 | * [0xABCDEF98] shift=12 mask=0xFFF value=0x123 => [0xAB123F98] |
| 51 | * |
| 52 | * Usage: |
| 53 | * # echo "CMD [OPTIONS] BANK ADRESS [VALUE]" > $debugfs/ab8500/hwreg |
| 54 | * |
| 55 | * CMD read read access |
| 56 | * write write access |
| 57 | * |
| 58 | * BANK target reg bank |
| 59 | * ADDRESS target reg address |
| 60 | * VALUE (write) value to be updated |
| 61 | * |
| 62 | * OPTIONS |
| 63 | * -d|-dec (read) output in decimal |
| 64 | * -h|-hexa (read) output in 0x-hexa (default) |
| 65 | * -l|-w|-b 32bit (default), 16bit or 8bit reg access |
| 66 | * -m|-mask MASK 0x-hexa mask (default 0xFFFFFFFF) |
| 67 | * -s|-shift SHIFT bit shift value (read:left, write:right) |
| 68 | * -o|-offset OFFSET address offset to add to ADDRESS value |
| 69 | * |
| 70 | * Warning: bit shift operation is applied to bit-mask. |
| 71 | * Warning: bit shift direction depends on read or right command. |
