    pinctrl: samsung: Add the support the multiple IORESOURCE_MEM for one pin-bank · 8b1bd11c
    Chanwoo Choi authored
    This patch supports the multiple IORESOURCE_MEM resources for one pin-bank.
    In the pre-existing Exynos series, the registers of the gpio bank are included
    in the one memory map. But, some gpio bank need to support the one more memory
    map (IORESOURCE_MEM) because the registers of gpio bank are separated into
    the different memory map.
    
    For example,
    The both ALIVE and IMEM domain have the different memory base address.
    The GFP[1-5] of exynos5433 are composed as following:
    - ALIVE domain : WEINT_* registers
    - IMEM domain  : CON/DAT/PUD/DRV/CONPDN/PUDPDN register
