2020-04-13soc / drm: mediatek: Fix mediatek-drm device probingEnric Balletbo i Serra1-12/+19
In the actual implementation the same compatible string "mediatek,<chip>-mmsys" is used to bind the clock drivers (drivers/soc/mediatek) as well as to the gpu driver (drivers/gpu/drm/mediatek/mtk_drm_drv.c). This ends with the problem that the only probed driver is the clock driver and there is no display at all. In any case having the same compatible string for two drivers is not correct and should be fixed. To fix this, and maintain backward compatibility, we can consider that the mmsys driver is the top-level entry point for the multimedia subsystem, so is not a pure clock controller but a system controller, and the drm driver is instantiated by that MMSYS driver.

Aside: There's a few other fb_create implementations which simply check for valid buffer format (or an approximation thereof), and then call drm_gem_fb_create. For atomic drivers at least we could walk all planes and make sure the format/modifier combo is valid, and remove even more code. For non-atomic drivers that's not possible, since the format list for the primary buffer might be garbage (and most likely it is). Also delete mtk_drm_fb.[hc] since it would now only contain one function.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+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.

2017-07-26drm: Convert to using %pOF instead of full_nameRob Herring1-8/+8
Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

2017-06-27drm/mediatek: separate color module to fixup error memory reallocation[email protected]1-2/+4
Previous patch (c5f228ef6c drm/mediatek: add *driver_data for different hardware settings) calls devm_kfree() and then devm_kzalloc() to reallocate color module data structure. But this reallocation cannnot guarantee the new address is unchanged, but the caller will use the old address, which is wrong. Fix it by separate color module from general components, this patch separate color module to independent files, like mtk_disp_ovl.c and mtk_disp_rdma.c do Fixes: c5f228ef6ccd ("drm/mediatek: add *driver_data for different hardware settings") Signed-off-by: YT Shen <[email protected]> Tested-by: Bibby Hsieh <[email protected]> Signed-off-by: CK Hu <ck.hu@mediatek>

2017-02-07drm: remove drm_vblank_no_hw_counter assignment from driver codeShawn Guo1-1/+0
Core code already makes drm_driver.get_vblank_counter hook optional by letting drm_vblank_no_hw_counter be the default implementation for the function hook. So the drm_vblank_no_hw_counter assignment in the driver code becomes redundant and can be removed now.
