PM / devfreq: rk3399_dmc: Add COMPILE_TEST and HAVE_ARM_SMCCC dependency

2020-02-28T14:42:28+00:00

[ Upstream commit eff5d31f7407fa9d31fb840106f1593399457298 ]

To build test, add COMPILE_TEST depedency to both ARM_RK3399_DMC_DEVFREQ
and DEVFREQ_EVENT_ROCKCHIP_DFI configuration. And ARM_RK3399_DMC_DEVFREQ
used the SMCCC interface so that add HAVE_ARM_SMCCC dependency to prevent
the build break.

PM / devfreq: exynos-nocp: Remove redundant code

2016-10-10T21:56:22+00:00

load_count/total_count are reset by devfreq_event_get_event(), so
remove the redundant code in exynos_nocp_get_event().

PM / devfreq: exynos-nocp: Select REGMAP_MMIO

2016-10-10T21:53:48+00:00

This driver uses devm_regmap_init_mmio(), so select REGMAP_MMIO to avoid
build failure.

PM / devfreq: event: support rockchip dfi controller

2016-09-06T04:25:35+00:00

on rk3399 platform, there is dfi conroller can monitor
ddr load, base on this result, we can do ddr freqency
scaling.

PM / devfreq: exynos-ppmu: remove unneeded of_node_put()

2016-09-06T04:08:40+00:00

for_each_child_of_node() performs an of_node_put() on each iteration, so
putting an of_node_put() before a continue results in a double put.

iounmap() needs to be called in case of memory allocation
(for devfreq-event devices) failure.  Fix it.

PM / devfreq: make event/exynos-ppmu DEVFREQ_EVENT_EXYNOS_PPMU tristate

2016-07-06T04:11:23+00:00

The Kconfig currently controlling compilation of this code is:

config DEVFREQ_EVENT_EXYNOS_PPMU
  bool "EXYNOS PPMU (Platform Performance Monitoring Unit) DEVFREQ event Driver"

...meaning that it currently is not being built as a module by anyone.

Rather than rip out the existing modular code, Chanwoo indicated
that he'd rather see the driver offered as tristate.

I don't have the hardware for runtime validation, so this change
is only validated for compile and modpost.

PM / devfreq: exynos-nocp: Remove incorrect IS_ERR() check

2016-06-22T04:52:55+00:00

Smatch complains because platform_get_resource() returns NULL on error
and not an error pointer so the check is wrong.  Julia Lawall pointed
out that normally we don't check these, because devm_ioremap_resource()
has a check for NULL.
