Missing at91-sama5d27_som1_ek_pda4.dtb in new kernels

Wed Nov 07, 2018 3:59 pm

Hello,
I have been succesfully using a kernel 4.9 with at91-sama5d27_som1_ek_pda4.dtb to test my SAMA5D27-SOM1-EK1.
Now I'd like to migrate to the latest kernel 4.14.73 but I'm wondering why all the PDA device tree files was removed form the sources.
Why?

Code: Select all

		at91-sama5d27_som1_ek.dtb \
		at91-sama5d27_som1_ek_pda4.dtb \
		at91-sama5d27_som1_ek_pda7.dtb \
		at91-sama5d27_som1_ek_pda7b.dtb \

Hi Marco,

We switched to adding the PDA screen additional nodes with DT overlays merged at boot time by U-Boot.
This way we are far closer to the Mainline sources and we can take advantage of this DT overlay possibility for other aspects like camera sensor selection for Image capture or daughter boards like click boards.
The sources of our DT overlays are here: https://github.com/linux4sam/dt-overlay-at91

Best regards,
Nicolas
