PM / devfreq: remove checks for CONFIG_EXYNOS_ASV

2014-05-24T13:33:51Z

Checks for CONFIG_EXYNOS_ASV were added in v3.3. But the related Kconfig symbol has never been added to the tree. Remove these checks, as they always evaluate to false. Signed-off-by: Paul Bolle [Merge conflict resolved by MyungJoo] Signed-off-by: MyungJoo Ham

PM / devfreq: exynos5: Add CONFIG_PM_OPP dependency to fix probe fail

2014-05-24T08:56:38Z

This patch add CONFIG_PM_OPP dependecy to exynos5_bus driver to fix probe fail. If CONFIG_PM_OPP is disabled, dev_pm_opp_find_freq_floor() will always return ERR_PTR(-EINVAL) error. Signed-off-by: Chanwoo Choi Reviewed-by: Tomasz Figa Signed-off-by: MyungJoo Ham

PM / devfreq: exynos4: Add CONFIG_PM_OPP dependency to fix probe fail

PM / devfreq: Disable Exynos4 driver build on multiplatform

2014-01-27T22:21:30Z

Exynos4 devfreq driver uses mach/map.h which is not available on multiplatform. Hence disable build on multiplatform for now. Without this patch we get the following build errors: drivers/devfreq/exynos/exynos4_bus.h:15:22: fatal error: mach/map.h: No such file or directory Signed-off-by: Sachin Kamat Signed-off-by: Rafael J.

PM / devfreq: fix typo "CPU_EXYNOS4.12" twice

2013-06-03T11:20:29Z

Dependencies on CPU_EXYNOS4212 and CPU_EXYNOS4412 for the "ARM Exynos4210/4212/4412 Memory Bus DEVFREQ Driver" were added in commit 7b4050381127ae11fcfc74a106d715a5fbbf888a ("PM/Devfreq: Add Exynos4-bus device DVFS driver for Exynos4210/4212/4412."). The tree (at that time, v3.3, and currently) makes clear that this should have been dependencies on SOC_EXYNOS4212 and SOC_EXYNOS4412. Signed-off-by: Paul Bolle

PM / devfreq: Add Exynos5-bus devfreq driver for Exynos5250

2013-06-03T11:20:29Z

Exynos5-bus device devfreq driver monitors PPMU counters and adjusts operating frequencies and voltages with OPP. ASV should be used to provide appropriate voltages as per the speed group of the SoC rather than using a constant 1.025V.

PM/Devfreq: Add Exynos4-bus device DVFS driver for Exynos4210/4212/4412.

2011-12-20T05:08:08Z

Exynos4-bus device devfreq driver add DVFS capability for Exynos4210/4212/4412-Bus (memory). The driver monitors PPMU counters of memory controllers and adjusts operating frequencies and voltages with OPP. For Exynos4210, vdd_int is controlled. For exynos4412/4212, vdd_mif and vdd_int are controlled. Dependency (CONFIG_EXYNOS_ASV): Exynos4 ASV driver has been posted in the mailing list; however, it si not yet upstreamed. Although the current revision of Exynos4 ASV patch does not contain "CONFIG_EXYNOS_ASV", we have added the symbol to hide the dependent from compilers for now. As soon as Exynos4 ASV drivers are merged, the #ifdef statement will be removed or the name will be changed. However, enabling ASV is essential in most Exynos4 chips to reduce the power consumption of Exynos4210 because without ASV, this Devfreq driver assumes the worst case scenario, which consumes more power. Signed-off-by: MyungJoo Ham Signed-off-by: Kyungmin Park --- Changes from v1 - Support 4212 and 4412 as well as 4210.
