8 | * AB8500 register access | |
9 | * ====================== | |
10 | * | |
11 | * read: | |
12 | * # echo BANK > <debugfs>/ab8500/register-bank | |
13 | * # echo ADDR > <debugfs>/ab8500/register-address | |
14 | * # cat <debugfs>/ab8500/register-value | |
15 | * | |
16 | * write: | |
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. | |
