Hi all,
i want to set gpio210 (aka. GPIO-C) to irq pin in Hikey960.
refer this thread → How do I set-up i2c node in dts file? - #3 by vvn2023
i2c device tree node like this.
ven-gpio = <&gpio26 0 0>;
firm-gpio = <&gpio26 2 0>;
irq-gpio = <&gpio26 4 0>;
it’s work but i want to exchange firm and irq pin gpio number, Due to my hardware configuration.
like tihs
ven-gpio = <&gpio26 0 0>;
irq-gpio = <&gpio26 2 0>;
firm-gpio = <&gpio26 4 0>;
but it is not work in latest 4.9 linaro kernel
This error occurs.
genirq: Failed to request resources for (irq 290) on irqchip pl061
irq-gpio = <&gpio26 4 0> is work but i have to do irq-gpio = <&gpio26 2 0>
how can i regester hikey960 gpio210 to isr?
pls help me
