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