Intersil chips ISL29018, ISL29023 and ISL29035 are very similar. They're
all ambience light sensors. The ISL29018, however, is also a proximity
sensor. The registers are similar too:
-------------+----------+----------
AVAILABLE IN | ADDR REG | NAME
290xx | |
-------------+----------+----------
18/23/35| 00h| COMMANDI
18/23/35| 01h| COMMANDII (B4-7 are used only in 29018 for proximity)
18/23/35| 02h| DATALSB
18/23/35| 03h| DATAMSB
18/23/35| 04h| INT_LT_LSB
18/23/35| 05h| INT_LT_MSB
18/23/35| 06h| INT_HT_LSB
18/23/35| 07h| INT_HT_MSB
18/23| 08h| TEST
35| 0Fh| ID
-------------+----------+-----------
So, this patch will add support for ISL29023 and ISL29035 to the
existing isl29018 driver. Since these 2 chips don't have proximity
detection, the proximity sysfs attribute is not needed.
Also, for ISL29035, since it has an ID register, make use of it in order
to properly detect the chip and clear the brownout bit.
