Subject: [PATCH 0/2] add support for partial pin space

A pin space of current pinctrl driver always start with zero-based pin
number. And pins are enumerated from 0 to a max pin number. If there are
two pins (one is 0, another is 1000), we always enumerate from 0 to 1000
for just only two pins. This patch enables to start non-zero based pin
number and to enumerate actually owned pins.

For example, there is a system which has huge(500 or 1000) pins. If muxing
or controlling pins are small, we just define such small pins instead of
whole pins.

Chanho Park (2):
  pinctrl: correct a offset while enumerating pins
  pinctrl: remove unnecessary max pin number
