Hi,
This series is the GPIO driver for Toshiba's ARM SoC, Visconti[0].
This provides DT binding documentation, device driver, MAINTAINER files, and updates to DT files.
Best regards,
Nobuhiro

v1 -> v2: Fix typo.
gpio: visoconti: Add Toshiba Visconti GPIO support:
v4 -> v5: Add IRQ_DOMAIN_HIERARCH to Kconfig
Updated for using hierarchical irqs.
v3 -> v4: Drop VISCONTI_GPIO_NR.
Fix return code of platform_irq_count.
Fix coprytight header.
Add Reviewed-by tag.
v2 -> v3: Add select GPIO_GENERIC
Use genric MMIO GPIO library
Use bgpio_init() as initialized the generic helpers.
Use irqchip template instead of gpiochip_irqchip_add().
v1 -> v2: No update
MAINTAINERS: Add entries for Toshiba Visconti GPIO controller:
v4 -> v5: No update
v3 -> v4: No update
v2 -> v3: No update
v1 -> v2: No update
arm: dts: visconti: Add DT support for Toshiba Visconti5 GPIO driver:
v4 -> v5: Drop interrupts property.
Add interrupts-parrent property.
