[PATCH RESEND 0/3] arm64: dts: qcom: fix GPIO lookup flags for i2c-gpio SDA and SCL pins

Posted by Bartosz Golaszewski 1 month, 3 weeks ago

Resending rebased on top of v6.17-rc1 as this missed the previous merge
window.

There are three platforms in the QCom DTS tree that are missing the
open-drain lookup flag in their DT nodes associated with the i2c-gpio
device whose driver enforces open-drain outputs. This causes the GPIO
core to emit warnings such as:

[    5.153550] gpio-528 (sda): enforced open drain please flag it properly in DT/ACPI DSDT/board file
[    5.166373] gpio-529 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file

Silence the warnings by adding appriopriate flags.
