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.
