2014-08-03drm/exynos/ipp: remove incorrect checks of list_first_entry resultAndrzej Hajda

2014-08-03drm/exynos: dsi: add driver data to support Exynos5410/5420/5440 SoCsYoungJun Cho
The offset of register DSIM_PLLTMR_REG in Exynos5410 / 5420 / 5440 SoCs is different from the one in Exynos4 SoCs. In case of Exynos5410 / 5420 / 5440 SoCs, there is no frequency band bit in DSIM_PLLCTRL_REG, and it uses DSIM_PHYCTRL_REG and DSIM_PHYTIMING*_REG instead. So this patch adds driver data to distinguish it.

2014-08-03drm/exynos: fimd: support LCD I80 interfaceYoungJun Cho
To support MIPI command mode based I80 interface panel, FIMD should do followings: - Sets LCD I80 interface timings configuration. - Uses "lcd_sys" as an IRQ resource and sets relevant IRQ configuration. - Sets LCD block configuration for I80 interface. - Sets ideal(pixel) clock is 2 times faster than the original one to generate frame done IRQ prior to the next TE signal. - Implements trigger feature that transfers image data if there is page flip request, and implements TE handler to call trigger function.

2014-08-03drm/exynos: dsi: add TE interrupt handler to support LCD I80 interfaceYoungJun Cho
This is a temporary solution and should be made by more generic way. To support LCD I80 interface, the DSI host should register TE interrupt handler from the TE GPIO of attached panel. So the panel generates a tearing effect synchronization signal then the DSI host calls the CRTC device manager to trigger to transfer video image.

2014-08-03drm/exynos: add TE handler to support LCD I80 interfaceYoungJun Cho
To support LCD I80 interface, the panel should generate Tearing Effect synchronization signal between MCU and FB to display video images. And the display controller should trigger to transfer video image at this signal. So the panel receives the TE IRQ, then calls these handler chains to notify it to the display controller.

2014-08-03drm/exynos: use wait_event_timeout() for safety usageYoungJun Cho
There could be the case that the page flip operation isn't finished correctly with some abnormal condition such as panel reset. So this patch replaces wait_event() with wait_event_timeout() to avoid waiting for page flip completion infinitely. And clears exynos_crtc->pending_flip in exynos_drm_crtc_page_flip() when exynos_drm_crtc_mode_set_commit() is failed.

2014-08-03drm/exynos: hdmi: enable exynos 4210 and 4x12 soc supportMarek Szyprowski
Configuration sets for Exynos 4210 and 4x12 SoC were already defined in Exynos HDMI and Mixed drivers, but they lacked proper linking to device tree 'compatible' values. This patch fixes this issue adding support for following compatible values: samsung,exynos4210-mixer, samsung,exynos4212-mixer and samsung,exynos4210-hdmi. It also corrects access to sclk_mixer clock, which is available only on Exynos 4210. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2014-08-03drm/exynos: hdmi: make 'hdmi-en' regulator optional and keep it enabledMarek Szyprowski
HDMI_EN regulator is additional regulator for providing voltage source for DCC lines available on HDMI connector. When there is no power provided for DDC epprom, some TV-sets do not pulls up HPD (hot plug detect) line, what causes HDMI block to stay turned off. This patch enables HDMI_EN regulator (if available) on driver probe and keep it enabled all the time to let TV-set correctly signal HPD event.

2014-08-03drm/exynos: Fix NULL pointer exception when suspending without componentsKrzysztof Kozlowski
Fix a NULL pointer exception when main exynos drm driver was probed successfully but no components were added (e.g. by incomplete DTS). In such case the exynos_drm_load() is never called and drvdata is NULL. The NULL pointer exception may theoretically also happen as a effect of race between adding components and main driver: if suspend of the driver happens before adding components.

2014-08-02r8152: add missing Makefile ruleJF Le Fillatre
Add missing Makefile rule for r8152 driver In the current kernel the r8152 driver is *never* built because of a missing rule in drivers/net/Makefile, despite being selected as built-in or module in the .config file. There is no error message or warning to indicate that the driver isn't built. This change adds the rule and lets the driver build. Tested as built-in and module for 3.15.8.

2014-08-02i40evf: future-proof vfr_stat state checkAshish Shah
Previously defined state I40E_VFR_VFACTIVE uses bit 1 which is now set to "reserved." Update the state checks to also include I40E_VFR_COMPLETED. This change will allow the VF to work with both existing and future PFs.

2014-08-02i40e: remove support for vf unicast promiscuous modeAshish Shah
Remove the ability of a VF to set unicast promiscuous mode. Considered to be a security risk to allow VFs to receive traffic intended for other VFs so don't allow it, simply ignore the flag. Also fix it to send the correct seid to aq for multicast promiscuous set.

2014-08-02i40e: disable local loopback on vmdq vsiShannon Nelson
The local loopback should only be enabled for VSIs that are supporting cascaded VEBs or VEPA setups. This is not the case here, and we need to stop the VEB from echoing the VMDQ VSI packets back at the VSI.

2014-08-02amd-xgbe-phy: Allow more time for Rx/Tx to become readyLendacky, Thomas
The current time range waiting for Rx/Tx to become ready can sometimes be too short if a connection is not present. Increase the number of retries and the sleep to give a bit more time. Also, change level of the message issued from _err to _dbg if Rx/Tx do not become ready since the underlying logic will function as if no link is established and retry eventually.

Instead, just enable SR-IOV with the resources provided by the FW. Prior to the "create optimal number of queues on SR-IOV config" patch such failures were ignored.
