2015-06-11drm/msm/dsi: Separate PHY to another platform deviceHai Li
There are different types of PHY from one chipset to another, while the DSI host controller is relatively consistent across platforms. Also, the PLL inside PHY is providing the source of DSI byte and pixel clocks, which are used by DSI host controller. Separated devices for clock provider and clock consumer make DSI driver better fit into common clock framework.

2015-06-11drm/msm/dsi: Enable PLL driver in MSM DSIHai Li
This change activates PLL driver for DSI to work with common clock framework. Signed-off-by: Hai Li <hali@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-06-11drm/msm/dsi: Add DSI PLL clock driver supportHai Li
DSI byte clock and pixel clocks are sourced from DSI PLL. This change adds the DSI PLL source clock driver under common clock framework. This change handles DSI 28nm PLL only.

2015-06-11drm/msm: use IS_ERR() to check regulator_get() returnFabian Frederick
regulator_get() never returns NULL. There's no need for IS_ERR_OR_NULL() Signed-off-by: Fabian Frederick <fabf@skynet.be> Signed-off-by: Rob Clark <robdclark@gmail.com>

2015-06-11drm/msm: dsi: Provide option to force continuous HS clockArchit Taneja
Some DSI peripherals rely on the HS clock on DSI clock lane as their clock source. If the clock lane transitions between HS and LP states, it can disrupt the functioning of such peripherals. The mipi dsi mode flag MIPI_DSI_CLOCK_NON_CONTINUOUS already exists for such peripheral drivers. Use it to configure the bit CLKLN_HS_FORCE_REQUEST in DSI_LANE_CTRL.

2015-05-14drm/msm/dsi: Simplify the code to get the number of read byteHai Li
During cmd rx, only new versions of H/W provide register to read back the real number of byte returned by panel. For the old versions, reading this register will not get the right number. In fact, we only need to assume the returned data is the same size as we expected, because later we will check the data type to detect error. Signed-off-by: Hai Li <hali@codeaurora.org>
2015-05-14drm/msm: Attach assigned encoder to eDP and DSI connectorsHai Li
drm_mode_connector_attach_encoder() function call is missing during eDP and DSI connector initialization. As a result, no encoder is returned by DRM_IOCTL_MODE_GETCONNECTOR system call. This change is to fix this issue. Signed-off-by: Hai Li <hali@codeaurora.org>

2015-05-14drm/msm/dsi: Fix a couple more 64-bit build warningsStephane Viau
Avoid such errors at compilation time: format '%d' expects argument of type 'int', but argument 3 has type 'size_t' Signed-off-by: Stephane Viau <sviau@codeaurora.org>
2015-04-20Merge Linus master into drm-nextDave Airlie
The merge is clean, but the arm build fails afterwards, due to API changes in the regulator tree. I've included the patch into the merge to fix the build. Signed-off-by: Dave Airlie <airlied@redhat.com>
2015-04-01drm/msm: Initial add DSI connector supportHai Li
