Hi,
My driver module used gpio9 as interrupt line with kernel 5.10 version but unable to use it because of gpio_to_irq api getting failed.
Below are my observation.
-
DTS parsing looks ok and getting gpio pin number as 370
-
Whenever gpio_to_irq() API called returning error -6
-
In the camera module this GPIO9 was used in dts config but we have commented 4. out also cross checked corresponding camera driver module config not enabled in .config
-
This GPIO9 problem observed with 5.10 kernel but same gpio was working fine on
5.4 kernel -
If just changed other gpio number it works fine in 5.10 kernel but we need to make it
work with GPIO9 only since our HW designed for that. -
Below is my dts config
&spi7 {
// On High speed expansion
label = “HS-SPI1”;
status = “okay”;
XYZ@0 {
compatible = “ppp,xyz”;
reg = <0>;
spi-max-frequency = <25000000>;
/* GPIO9 /
ppp,pp200-irq = <&tlmm 9 0>;
/ GPIO83 (PIN 19) */
ppp,pp200-reset = <&tlmm 83 0>;
};
};
Anybody have idea on this issue?
