[PATCH v1 0/2] riscv: add GPIO support for the LicheePi4A
From: Maksim Kiselev bigunclemax@gmail.com
This series adds GPIO support for the LicheePi4A board. It's based on Alibaba TH1520 SoC that has DesignWare APB GPIO controller.
Best regards, Maksim

Starting with Linux commit 7569486d79ae ("gpio: dwapb: Add ngpios DT-property support") the "snps,nr-gpios" property was marked as deprecated.
And since all newly added dw-apb-gpio nodes are described using generic "ngpios" property, it's time to add support for it.
