* Linux: Update kernel 5.15.25 Use highest available kernel version in Buildroot 2021.08 (5.13) * Update Hardkernel patches to Linux 5.15 * Update generic-x86-64/ova kernel config/patches for 5.15 * Drop Intel e1000e Sourceforge driver The driver has been discontinued sometime last year. The main reason the out-of-tree kernel has been enabled was for support for the i219-V network chips which meanwhile are supported in mainline.

Subject: [PATCH 3/7] arm64: dts: meson: g12b: odroid-n2: add fan as cooling

Add the GPIO fan as a cooling device for the CPU thermal zone. Since we
|
|
have only full fan speed available with this, set the tripping point to
|
|
65°C which is the highest tripping point which Hardkernel used in their
|
|
downstream kernel.
