2014-05-15usb: usb5303: add support for reference clock specified in device treeMarek Szyprowski1-2/+26
USB3503 chip supports 8 values of reference clock. The value is specified by REF_SEL[1:0] pins and INT_N line. This patch add support for getting 'refclk' clock, enabling it and setting INT_N line according to the value of the gathered clock. If no clock has been specified, driver defaults to the old behaviour (assuming that clock has been specified by REF_SEL pins from primary reference clock frequencies table).

2014-05-15drivers: phy: exynos4x12-phy: fix HSIC1 power on/off sequenceMarek Szyprowski2-15/+35
From experiments with real hardware, it seems that URSTCON bits for HSIC0 and HSIC1 seems to be swapped, so updated macro definitions for them. HSIC1 also requires enabling power to device phy to get properly enabled (similar hack is already implemented for HSIC0).

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: fix kernel oops in phy_lookup()Sergei Shtylyov1-0/+3
The kernel oopses in phy_lookup() due to 'phy->init_data' being NULL if we register PHYs from a device tree probing driver and then call phy_get() on a device that has no representation in the device tree (e.g. a PCI device). Checking the pointer before dereferening it and skipping an interation if it's NULL prevents this kernel oops.

2014-05-15drivers: phy: Make NULL a valid phy referenceAndrew Lunn1-1/+16
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.

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>
