2020-08-19drm: gma500: Convert to GPIO descriptorsLinus Walleij1-1/+0
Finalize he conversion of GMA500 to use only GPIO descriptors. The GPIO look-up-table is associated with the device directly in the GMA500 Medfield chip driver since no explicit platform type device (such as in x86/platform/intel-mid) exists: the GMA500 probes directly from the PCI device. Apparently GPIOs 128 and 34 are used on all of these so just go ahead and register those for resetting the DSI pipes.

2020-05-27drm/gma500: Stop using mode->private_flagsVille Syrjälä1-19/+0
gma500 only uses mode->private_flags to convey the sdvo pixel multiplier from the encoder .mode_fixup() hook to the encoder .mode_set() hook. Those always seems get called as a pair so let's just stuff the pixel multiplier into the encoder itself as there are no state objects we could use in this non-atomic driver. Paves the way for nuking mode->private_flag.

2020-04-02drm/gma500: Use simple encoderThomas Zimmermann1-1/+0
The gma500 driver uses empty implementations for some of its encoders. Replace the code with the generic simple encoder. As a side effect, the patch also removes an indirection in the encoder setup for Medfield.

2019-11-07drm/gma500: Add page flip support on psb/cdvPaul Kocialkowski1-0/+3
Legacy (non-atomic) page flip support is added to the driver by using the mode_set_base CRTC function, that allows configuring a new framebuffer for display. Since the function requires the primary plane's fb to be set already, this is done prior to calling the function in the page flip helper and reverted if the flip fails. The vblank interrupt handler is also refactored to support passing an event. The PIPE_TE_STATUS bit is also considered to indicate vblank on medfield only, as explained in psb_enable_vblank. It was tested by running weston on both poulsbo and cedartrail.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-0/+1
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2016-12-18drm: Don't include <drm/drm_encoder.h> in <drm/drm_crtc.h>Laurent Pinchart1-0/+1
<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

We do not support 3D or the video overlays. In theory enough public info is available to do the video overlay work but that represents a large task. Framebuffer X will run nicely with this but do *NOT* use the VESA X server at the same time as KMS.
