* PM / devfreq: exynos: Remove unused exynos4/5 busfreq driverChanwoo Choi2016-05-031-1055/+0
| | | | | | | | | This patch removes the unused exynos4/5 busfreq driver. Instead, generic exynos-bus frequency driver support the all Exynos SoCs.

* devfreq: exynos: drop owner assignment from platform_driversWolfram Sang2014-10-201-1/+0
| | | | | | | A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* PM / devfreq: remove checks for CONFIG_EXYNOS_ASVPaul Bolle2014-05-241-13/+4
| | | | | | | | | | 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.

* PM / devfreq: exynos4: use common PPMU codeChanwoo Choi2014-05-241-103/+61
| | | | | | | | | | | | | This patch converts exynos4_bus driver to use common PPMU code (exynos_ppmu.c) instead of individual functions related to PPC because PPMU is integrated module with both PPC and Bus event generator. When using PPMU to get bus performance read/write event exynos4_bus driver deson't need to consider memory type.
