PM / devfreq: Skip status update on uninitialized previous_freq

2016-10-10T22:01:20Z

In case devfreq->previous_freq is still uninitialized in devfreq_update_status(), i.e. it has value '0', the lookups in that function fail, eventually leading to some error message: [ 3.041292] devfreq bus_dmc: Couldn't update frequency transition information. Just skip the statup update in this situation. Signed-off-by: Tobias Jakobi Acked-by: MyungJoo Ham Signed-off-by: Rafael J. Wysocki

PM / devfreq: exynos-nocp: Select REGMAP_MMIO

This driver uses devm_regmap_init_mmio(), so select REGMAP_MMIO to avoid build failure. Signed-off-by: Axel Lin Acked-by: Chanwoo Choi Signed-off-by: Rafael J. Wysocki

PM / devfreq: rk3399_dmc: Remove explictly regulator_put call in .remove

2016-09-19T11:36:20Z

Current code uses devm_regulator_get() in .probe so a regulator_put() will be automatically called when unload the module. Remove the explictly regulator_put() call and then we can also remove rk3399_dmcfreq_remove(). Signed-off-by: Axel Lin Reviewed-by: Chanwoo Choi Acked-by: MyungJoo Ham Signed-off-by: Rafael J.

PM / devfreq: rockchip: add PM_DEVFREQ_EVENT dependency

2016-09-19T11:12:17Z

The newly added ARM_RK3399_DMC_DEVFREQ driver requires the DEVFREQ_EVENT_ROCKCHIP_DFI driver and tries to turn that on through a 'select' statement, and that in turn has a dependency on PM_DEVFREQ_EVENT, which may be disabled here: warning: (ARM_RK3399_DMC_DEVFREQ) selects DEVFREQ_EVENT_ROCKCHIP_DFI which has unmet direct dependencies (PM_DEVFREQ && PM_DEVFREQ_EVENT && ARCH_ROCKCHIP) We probably want a 'depends on' here, but other drivers use 'select' too, so for consistency I'm doing the same.
