Subject: [PATCH 0/3] clk: renesas: Set GENPD_FLAG_ALWAYS_ON for clock domain
Date: Fri, 16 Aug 2019 14:52:22 +0200 [thread overview]
Message-ID: <20190816125225.16061-1-geert+renesas@glider.be> (raw)
Hi Mike, Stephen,
The Renesas Clock Domain drivers do not implement the
generic_pm_domain.power_{on,off}() callbacks, as the domains themselves
cannot be powered down. Hence the domains should be marked as always-on
by setting the GENPD_FLAG_ALWAYS_ON flag.
This patch series that issue for R-Car M1A, RZ/A1, RZ/A2, and
RZ/N1 SoCs.
SH/R-Mobile SoCs are fixed in "[PATCH] soc: renesas: rmobile-sysc: Set
GENPD_FLAG_ALWAYS_ON for always-on domain"
(https://lore.kernel.org/linux-renesas-soc/20190816124106.15383-1-geert+renesas@glider.be/T/#u).
R-Car H1, Gen2, and Gen3 SoCs do not need a fix, as these SoCS use the
R-Car SYSC driver for Clock Domain creation, which already sets the
flag.
To be queued in clk-renesas for v5.4.
Thanks!
