pinctrl: samsung: Add the support the multiple IORESOURCE_MEM for one pin-bank
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 Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Rob Herring <robh+dt@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Tomasz Figa <tomasz.figa@gmail.com> Cc: Krzysztof Kozlowski <krzk@kernel.org> Cc: Sylwester Nawrocki <s.nawrocki@samsung.com> Cc: Kukjin Kim <kgene@kernel.org> Cc: linux-gpio@vger.kernel.org Suggested-by: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
