Add MODULE_DEVICE_TABLE calls for the various OF match tables that currently don't have one. This allows the module to be autoloaded based on devicetree information. Signed-off-by:

This reverts commit d0896218 was original to prevent multiple MODULE_DEVICE_TABLE in one module. Which, as a side-effect broke autoloading of the module. Since 21bdd17b it is possible to have multiple calls to MODULE_DEVICE_TABLE, so the patch can be reverted to restore support for autoloading Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

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.

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. Signed-off-by:

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:

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.

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.

Peter Anvin <hpa@linux.intel.com> Date: Wed Nov 28 11:50:24 2012 -0800 x86, 386 removal: Remove CONFIG_CMPXCHG All 486+ CPUs support CMPXCHG, so remove the fallback 386 support code. Furthermore, as the commit-message states, all 486+ CPUs support the CMPXCHG instruction and thus even legacy DRM can run fine. Drop the now superfluous "x86 == 3" check.
