2014-05-15PM / devfreq : Make exynos4 busfreq driver to use PPMU not DMC internal one.sandbox/cosmichobo/tizenJonghwa Lee4-104/+107
This patch modifies exynos4 busfreq driver to use global PPMU not DMC block's internal PMU. The PPMU has different event set with DMC's and it'll be more adaquate to profile bus utilization. Change-Id: Ia5f6801cf6081edf5c76cad2af86978843bdf91a Signed-off-by: Jonghwa Lee <jonghwa3.lee@samsung.com>

2014-05-15PM / devfreq: Rewrite devfreq_update_status() to fix multiple bugsSaravana Kannan1-11/+20
The current devfreq_update_status() has the following bugs: - If previous frequency doesn't have a valid level, it does an out of bounds access into the trans_table and causes memory corruption. - When the new frequency doesn't have a valid level, the time spent in the new frequency is counted towards the next valid frequency switch instead of being ignored. - The time spent on the previous frequency is added to the new frequency's stats instead of the previous frequency's stats. This patch fixes all of this. Change-Id: I9e3bb6ac6490d8f2e4bca2fd0d082f2fbd4a5b2e Signed-off-by: Saravana Kannan <skannan@codeaurora.org> Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>

2014-05-15phy: exynos: fix building as a moduleArnd Bergmann1-3/+4
The top-level phy-samsung-usb2 driver may be configured as a loadable module, which currently causes link errors because of the dependency on the exynos{5250,4x12,4210}_usb2_phy_config symbol. Solving this could be achieved by exporting these symbols, but as the SoC-specific parts of the driver are not currently built as modules, it seems better to just link everything into one module and avoid the need for the export.

2014-05-15phy: core: make NULL a valid phy reference if !CONFIG_GENERIC_PHYGrygorii Strashko1-0/+16
This fixes a regression on Keystone 2 platforms caused by patch 57303488cd37da58263e842de134dc65f7c626d5 "usb: dwc3: adapt dwc3 core to use Generic PHY Framework" which adds optional support of generic phy in DWC3 core. On Keystone 2 platforms the USB is not working now because CONFIG_GENERIC_PHY isn't set and, as result, Generic PHY APIs stubs return -ENOSYS always. The log shows: dwc3 2690000.dwc3: failed to initialize core dwc3: probe of 2690000.dwc3 failed with error -38 Hence, fix it by making NULL a valid phy reference in Generic PHY APIs stubs in the same way as it was done by the patch 04c2facad8fee66c981a51852806d8923336f362 "drivers: phy: Make NULL a valid phy reference".

2014-05-15drivers: phy: Make NULL a valid phy referenceAndrew Lunn2-1/+22
The common clock framework considers NULL a valid clock reference. This makes handling optional clocks simple, in that if the optional clock is not available, a NULL reference can be used in the place of a real clock, simplifying the clock consumer. Extend this concept to the phy consumer API. A NULL can be passed to the release calls, the phy_init() and phy_exit() calls, and phy_power_on() and phy_power_off() and a NOP is performed.

In case pm_runtime_get*() fails, it still increments pm usage counter, so we *must* make sure to pm_runtime_put() even in those cases. This patch fixes that mistake the same way usbcore treats those possible failures.

2014-05-15drivers: phy: tweaks to phy_create()Dan Carpenter1-16/+10
If this was called with a NULL "dev" then it lead to a NULL dereference when we called dev_WARN(). I have changed it to WARN_ON() so that we get a stack dump and can fix the caller. The rest of this patch is just cleanup like returning directly instead of having do-nothing gotos. Using descriptive labels instead of GW-BASIC style "err0" and "err1". I also flipped the order of put_device() and ida_remove() so they are a mirror reflection of the order they were allocated.

2014-05-15drm/exynos: hdmi: fix dt broken issueInki Dae1-18/+70
This patch resolves the issue that the use of existing dtb is broken. This patch gets existing dt nodes directly and checks if existing dtb should be supported or not. For this, it adds a soc_ver varable to hdmi_context structure to distinguish SoC version because it should get dt node corresponding to SoC correctly. Signed-off-by: Inki Dae <inki.dae@samsung.com>

2014-05-15drm/exynos: release unhandled page flip events at postclose.Inki Dae1-13/+22
This patch resolves a dead lock issue that could be incurred when exynos_drm_crtc_dpms function was called. The exynos_drm_crtc_dpms function waits for the completion of pended page flip events. However, preclose callback - this releases all unhandled page flip events - is called prior to the exynos_drm_crtc_dpms function call when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms to wait infiniately for the completion of the page flip events. This patch releases the unhandled page flip events at postclose instead of preclose so that exynos_drm_crtc_dpms function can be waked up. Changelog v2: - fix a memory leak when drm is closed. . it has a memory leak when a requeste page flip is handled after drm_events_release() is called and before drm_fb_release() is called. At this time, a drm_pending_event will not be freed. So also this chage releases the drm_pending_event at postclose(). And it calls drm_vblank_put() for pair if there is any unhandled page flip event. Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
