From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dmitry Torokhov Subject: [PATCH v2] cpufreq: dt-platdev: allow RK3399 to have separate tunables per cluster Date: Fri, 5 Oct 2018 12:00:58 -0700 Message-ID: <20181005190058.GA234868@dtor-ws> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org To: "Rafael J. Wysocki" , Viresh Kumar Cc: Heiko Stuebner , Derek Basehore , Guenter Roeck , linux-pm@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-pm@vger.kernel.org RK3899 has one cluster with 4 small cores, and another one with 2 big cores, with cores in different clusters having different OPPs and thus needing separate set of tunables. Let's enable this via "have_governor_per_policy" platform data. Signed-off-by: Dmitry Torokhov --- v2 changes: commit message updated. Not tested, but we had a patch unconditionally enabling CPUFREQ_HAVE_GOVERNOR_PER_POLICY flag in tree we used to ship devices based on RK3399 platform. drivers/cpufreq/cpufreq-dt-platdev.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/cpufreq/cpufreq-dt-platdev.c b/drivers/cpufreq/cpufreq-dt-platdev.c index fe14c57de6ca..040ec0f711f9 100644 --- a/drivers/cpufreq/cpufreq-dt-platdev.c +++ b/drivers/cpufreq/cpufreq-dt-platdev.c @@ -78,7 +78,10 @@ static const struct of_device_id whitelist[] __initconst = { { .compatible = "rockchip,rk3328", }, { .compatible = "rockchip,rk3366", }, { .compatible = "rockchip,rk3368", }, - { .compatible = "rockchip,rk3399", }, + { .compatible = "rockchip,rk3399", + .data = &(struct cpufreq_dt_platform_data) + { .have_governor_per_policy = true, }, + }, { .compatible = "st-ericsson,u8500", }, { .compatible = "st-ericsson,u8540", }, -- 2.19.0.605.g01d371f741-goog -- Dmitry
