pinctrl/nomadik: allow to support several ranges per GPIO bank
With DB8500 the number of GPIO chips = number GPIO bank = number of GPIO ranges. With DB8540, a new GPIO range configuration is used, some GPIO banks can have several GPIO ranges. For example, DB8540 GPIO bank0 (GPIO0 to GPIO32) have 2 GPIO ranges: - GPIO0 to GPIO17 : routed - GPIO18 to GPIO21 : hole - GPIO22 to GPIO28 : routed - GPIO29 to GPIO32 : hole Previously, during nmk_pinctrl_probe(), all GPIO ranges were parsed, as GPIO ranges are larger than the number of GPIO chips, a warning occurs. This commit allows each bank to have several GPIO ranges. Signed-off-by: Patrice Chotard <patrice.chotard@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
