From f47a08d1a71825c10188968251e6f4a8ef647b99 Mon Sep 17 00:00:00 2001 From: =?utf8?q?C=C3=A9dric=20Le=20Goater?= Date: Tue, 23 Jul 2019 11:01:38 +0200 Subject: [PATCH] ppc/pnv: Generate phandle for the "interrupt-parent" property MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Devices such as the BT or serial devices require a valid "interrupt-parent" phandle in the device tree and it is currently empty (0x0). It was not a problem until now but since OpenFirmare started using a recent libdft (>= 1.4.7), petitboot fails to boot the system image with error : dtc_resize: fdt_open_into returned FDT_ERR_BADMAGIC Provide a phandle for the LPC bus.
