HISILICON HIGH PERFORMANCE RSA ENGINE DRIVER (HPRE)
Add the new compatible for HiSilicon gpio controller driver. Signed-off-by: Weilong Chen <chenweilong@huawei.com> --- Change since v2: - No change. Link: https://lore.kernel.org/lkml/20221028022453.163186-2-chenweilong@huawei.com/ Change since v1: - Drop "Device Tree Bindings" and reg's description - Move description in top-level description. - Add gpio-cells to required - Use additionalProperties and decimal numbers - Use IRQ flags - Use vendor,soc-ipblock format Link: https://lore.kernel.org/lkml/20221026034219.172880-2-chenweilong@huawei.com/ .../gpio/hisilicon,ascend910-gpio.yaml | 56 +++++++++++++++++++ MAINTAINERS | 1 + 2 files changed, 57 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/hisilicon,ascend910-gpio.yaml
