gpio: tegra: Iterate over the correct number of banks When Tegra30 support was added to the Tegra GPIO driver, a few places which iterated over all banks were not converted to use the variable tegra_gpio_bank_count rather than hard-coding the bank count. Fix this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Olof Johansson <olof@lixom.net>

gpio: tegra: fix register address calculations for Tegra30 Tegra20 and Tegra30 share the same register layout within registers, but the addresses of the registers is a little different. Fix the driver to cope with this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Olof Johansson <olof@lixom.net>

gpio: tegra: Fix build issue due to irq_domain rework. Commit 7da5a66 "irq_domain: Remove 'new' irq_domain in favour of the ppc one" changed the set of available irq domain APIs. Update the Tegra GPIO driver to account for those changes, to solve a build break. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Olof Johansson <olof@lixom.net>

gpio: tegra: Dynamically allocate IRQ base, and support DT Enhance the driver to dynamically allocate the base IRQ number, and create an IRQ domain for itself. The use of an IRQ domain ensures that any device tree node interrupts properties are correctly parsed. Describe interrupt-related properties in the device tree binding docs, and the contents of "child" node interrupts property. Update tegra*.dtsi to specify the required interrupt-related properties. Finally, remove the definition of TEGRA_GPIO_TO_IRQ; this macro no longer gives correct results since the IRQ numbers for GPIOs are dynamically allocated.
