soc: renesas: rcar-sysc: Make PM domain initialization more robust

2018-06-08T08:04:25Z

The quirk for R-Car E3 ES1.0 added in commit 086b399965a7ee7e ("soc: renesas: r8a77990-sysc: Add workaround for 3DG-{A,B}") makes the 3DG-A PM domain a subdomain of the 3DG-B PM domain. However, registering 3DG-A with its parent fails silently, as the 3DG-B PM domain hasn't been registered yet, and such failures are never reported. Fix this by: 1. Splitting PM Domain initialization in two steps, so all PM domains are registered before any child-parent links are established, 2. Reporting any failures in establishing child-parent relations. Check for and report pm_genpd_init() failures, too, as that function gained a return value in commit 7eb231c337e00735 ("PM / Domains: Convert pm_genpd_init() to return an error code").
