2016-05-17drm: Remove unused drm_device from drm_gem_object_lookup()Chris Wilson
drm_gem_object_lookup() has never required the drm_device for its file local translation of the user handle to the GEM object. Let's remove the unused parameter and save some space.

2016-05-08drm/msm: Centralize connector registration/unregistrationArchit Taneja
Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers to the msm platform driver. This will simplify the task of ensuring that the connectors are registered only after the drm_device itself is registered. The connectors' destroy ops are made to use kzalloc instead of devm_kzalloc to ensure that that the connectors can be successfully unregistered when the msm driver module is removed. The memory for the connectors is unallocated when drm_mode_config_cleanup() is called during either during an error or during driver remove.

2016-05-08drm/msm/mdp4: Don't manage DSI PLL regulators in MDP driverArchit Taneja
The MDP4 driver tries to request and set voltages for regulators required by the DSI PLLs. Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should be handled in the DSI driver. Secondly, it shouldn't try to set a fixed voltage for regulators. Voltage constraints should be specified on the regulator via DT and managed by the regulator core. Remove all the DSI PLL regulator related code from the MDP4 driver. It's managed in the DSI driver for MSM8960/APQ8064 already.

2016-03-03drm/msm: rename hdmi symbolsArnd Bergmann
Global symbols in the kernel should be prefixed by the name of the subsystem and/or driver to avoid conflicts when all code is built-in. In this case, function names like 'hdmi_register' or 'hdmi_set_mode' are way too generic for an MSM specific DRM driver, so I'm renaming them all to msm_hdmi_* here. I also rename a lot of the 'static' symbols along with the global names for consistency, even though those are relatively harmless; they might only be slightly confusing when they show up in backtraces.

2015-12-14drm/msm/mdp4: Initialize LCDC encoder even if panel driver isn't availableArchit Taneja
Currently, the driver defers if it doesn't find a drm_panel. This forces us to have a drm_panel, if not, the driver isn't usable. Make the lcdc encoder initialization independent of the availability of the drm panel. We only check if there is a panel node specified in DT. If it isn't, then we don't initialize the encoder at all. The panel node is passed to the lcdc encoder and lvds connector drivers. The connector driver takes the responsibility to retrieve the drm_panel from the panel node, and update the status on whether the panel is connected or not. This makes the panel usable even if the drm_panel driver is inserted as a module later on. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

The line counter starts with the value 1 at the beginning of the VSYNC pulse and ends with value VTOTAL at the end of VFP. This value is used to determine whether we're in blanking period or not, and an adjusted value of this counter is used to get vpos as expected by get_scanout_position. Since there is no way to calculate hpos, we always set it to 0. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

In order to produce an image, the scalar needs to be fed extra pixels.

Pixel Extension are programmed by hardware in most targets - and can be overwritten by software. For some targets (e.g.: msm8996), software *must* program those registers.

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

Add packed YUV422 and planar YUV420 formats to MDP supported formats. Signed-off-by: Stephane Viau <sviau@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-08-15drm/msm/mdp5: use 2 memory clients for YUV formats on newer mdp5Wentao Xu
Newer MDP5 uses 2 shared memory pool clients for certain YUV formats. For example, if VIG0 is used to fetch data in YUYV format, it will use VIG0_Y for Y component, and VIG0_Cr for UV packed.

2015-08-15drm/msm/mdp: mark if a MDP format is YUV at definitionWentao Xu
This makes it easy to determine if a format is YUV. The old method of using chroma sample type incorrectly marks YUV444 as RGB format. Signed-off-by: Wentao Xu <wentaox@codeaurora.org> [rebase] Signed-off-by: Stephane Viau <sviau@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-08-15drm/msm/mdp5: Allocate CTL0/1 for dual DSI single FLUSHHai Li
This change takes advantage of a HW feature that synchronize flush operation on CTL1 to CTL0, to keep dual DSI pipes in sync. Signed-off-by: Hai Li <hali@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-08-15drm/msm/mdp5: Allocate CTL for each display interfaceHai Li
In MDP5, CTL contains information of the whole pipeline whose output goes down to a display interface. In various cases, one interface may require 2 CRTCs, but only one CTL. Some interfaces also require to use certain CTLs. Instead of allocating CTL for each active CRTC, this change is to associate a CTL with each interface.

2015-08-15drm/msm/mdp5: Add plane blending operation support for MDP5 (v2)jilai wang
This change is to add properties alpha/zpos/blend_mode to mdp5 plane for alpha blending operation to generate the blended output. v1: Initial change v2: Change "premultilied" property to enum (Rob's comment) Signed-off-by: Jilai Wang <jilaiw@codeaurora.org> [Don't actually expose alpha/premultiplied props to userspace yet pending a chance for discussion and some userspace to exercise it] Signed-off-by: Rob Clark <robdclark@gmail.com>
