From 8070ba6348608aa1da15eb83dbaa9ece596aaa67 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 10 Dec 2018 22:00:23 +0100 Subject: ARM: shmobile: fix build regressions A number of Kconfig options have become available now to random ARM platforms outside of ARCH_MULTIPLATFORM, which now causes Kconfig warnings, and other build errors when those select options that lack additional dependencies, e.g.: WARNING: unmet direct dependencies detected for HAVE_ARM_ARCH_TIMER Depends on [n]: CPU_V7 [=n] Selected by [y]: - ARCH_RCAR_GEN2 [=y] && SOC_RENESAS [=y] - ARCH_R8A73A4 [=y] && SOC_RENESAS [=y] && ARM [=y] WARNING: unmet direct dependencies detected for SYS_SUPPORTS_EM_STI Depends on [n]: GENERIC_CLOCKEVENTS [=n] Selected by [y]: - ARCH_EMEV2 [=y] && SOC_RENESAS [=y] && ARM [=y] Put the old dependency on ARCH_RENESAS back for the moment to restore the previous behavior.

However, the 3DG-{A,B} power domains were still initialized and powered in the wrong order, causing 3DG operation to fail. Fix this by changing the order in the table at runtime, when running on an affected SoC. This work is based on the work done by Geert for R-Car E3.
