Versatile DTS updates for the v5.8 kernel:
Create a new device tree for the Integrator/AP with the IM-PD1 expansion module fitted in the first slot. If we want to augment the slot where it is sitting, we can alter the device tree or make the bootloader do so. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEElDRnuGcz/wPCXQWMQRCzN7AZXXMFAl6oi4YACgkQQRCzN7AZ XXOpVBAAxco/qwxQndEPMWDVCtqOdhXglUvq220V5PQ4DNvpm52QeG65rwwR2TK9 Nun/vW70JZnXysGS4ZAU9NKToenyIdacwfFCea1eDK7cWpbZzZGo3dkMsr90KBah iGDx1ua/lAPxP+IhGlv8GBFQ4rMYzBewaAvk30pi3FtoV/gUjszqLUX1UI7TTaEA LWlI4t9aFrRryTsffVzCMXKWUbovMfPtf7dvi+H+Paid8x5PVRwpo91eLknydwb6 BQAxFhaNy34U27DIsH4L2ulcy7xFBwlmOVHA8h9cTq5qFF/ASxAhAmdQvg+DzjqK 8YZkWAgOMfwuY+zDFHsvGMJXWZeNOfo76tV0QhiHPlC9JcvOxc95SH7SDwTVjQ/v JyLfqMxz6VaL4tL5j2APHgjQzpNtOs6aPNiUkmxrz3iLGuzi51f+Ua/I5MbYd2ME oyW21YIebHtiHhZ30NenS0hnD2prFzsdDZLgI04LKwCTW56xM2XS7diz1if+yxJ8 49LWboInAq8B4ipuRmzNrUoWZlcYZcdUh/7gi1xCwkdpg0rNj/3hKzeRf3W78yw2 Tve2E2TK+I+l4bJclCjdYzbkWUkheZWApx5nK+4kAAwS+rr1AM4oXZYtd7530LUK YL9CavQeDL8SfW8zzCVooureO9MDdzYb5o+joKhaBejgvCGThOg= =XZ07 -----END PGP SIGNATURE----- Merge tag 'versatile-dts-v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into arm/dt Versatile DTS updates for the v5.8 kernel: Create a new device tree for the Integrator/AP with the IM-PD1 expansion module fitted in the first slot.
