BCM2835's PLLD_DSI1 divider doesn't give us many choices for our pixel clocks, so to support panels on the Raspberry Pi we need to set a higher pixel clock rate than requested and adjust the mode we program to extend out the HFP so that the refresh rate matches. v2: Drop an unfinished comment (caught by Noralf) Signed-off-by:

With the Cygnus port, we needed to add at least "|| ARCH_BCM_CYGNUS" to let the module get built on a cygnus-only kernel. However, I anticipate having a port for Kona soon, so just present the module on all of BCM. v2: Keep allowing selection with ARCH_BCM2835, since ARCH_BCM doesn't exist on arm64.

In the previous patch we've implemented hwmode tracking a la i915 for the vblank timestamp calculations. But that was just the basic semantics, i915 has some nice sanity checks to make sure we keep getting this right.

If we restrict this helper to only kms drivers (which is the case) we can look up the correct mode easily ourselves. But it's a bit tricky: - All legacy drivers look at crtc->hwmode. But that is updated already at the beginning of the modeset helper, which means when we disable a pipe. Hence the final timestamps might be a bit off. But since this is an existing bug I'm not going to change it, but just try to be bug-for-bug compatible with the current code. This only applies to radeon&amdgpu. - i915 tries to get it perfect by updating crtc->hwmode when the pipe is off (i.e. vblank->enabled = false). - All other atomic drivers look at crtc->state->adjusted_mode. Those that look at state->requested_mode simply don't adjust their mode, so it's the same. That has two problems: Accessing crtc->state from interrupt handling code is unsafe, and it's updated before we shut down the pipe. For nonblocking modesets it's even worse. For atomic drivers try to implement what i915 does. To do that we add a new hwmode field to the vblank structure, and update it from drm_calc_timestamping_constants(). For atomic drivers that's called from the right spot by the helper library already, so all fine. But for safety let's enforce that. For legacy driver this function is only called at the end (oh the fun), which is broken, so again let's not bother and just stay bug-for-bug compatible. The benefit is that we can use drm_calc_vbltimestamp_from_scanoutpos directly to implement ->get_vblank_timestamp in every driver, deleting a lot of code. v2: Completely new approach, trying to mimick the i915 solution. v3: Fixup kerneldoc. v4: Drop the WARN_ON to check that the vblank is off, atomic helpers currently unconditionally call this. Recomputing the same stuff should be harmless. v5: Fix typos and move misplaced hunks to the right patches (Neil). v6: Undo hunk movement (kbuild).

It's overkill to have a flag parameter which is essentially used just as a boolean. This takes care of core + adjusting drivers. Adjusting the scanout position callback is a bit harder, since radeon also supplies it's own driver-private flags in there. v2: Fixup misplaced hunks (Neil). v3: kbuild says v1 was better ...

There's really no reason for anything more: - Calling this while the crtc vblank stuff isn't set up is a driver bug. Those places alrready DRM_ERROR. - Calling this when the crtc is off is either a driver bug (calling drm_crtc_handle_vblank at the wrong time) or a core bug (for anything else). Again, we DRM_ERROR. - EINVAL is checked at higher levels already, and if we'd use struct drm_crtc * instead of (dev, pipe) it would be real obvious that those are again core bugs. The only valid failure mode is crap hardware that couldn't sample a useful timestamp, to ask the core to just grab a not-so-accurate timestamp. Bool is perfectly fine for that. v2: Also fix up the one caller, I lost that in the shuffling (Jani). v3: Fixup commit message (Neil).

With all drivers converted there's only legacy dri1 drivers using it. Not going to touch those, instead just hide it like we've done with other dri1 driver hooks like firstopen. In all this I didn't find any real reason why we'd needed 2 hooks, and having symmetry between open and close just appeases my OCD better. Yeah, someone else could do an s/postclose/close/, but that's for someone who understands cocci. And maybe after this series is reviewed and landed, to avoid patch-regen churn. v2: s/last/post/close in the kernel-doc (Sean). Reviewed-by:

This is a modesetting driver for the pl111 CLCD display controller found on various ARM platforms such as the Versatile Express. The driver has only been tested on the bcm911360_entphn platform so far, with PRIME-based buffer sharing between vc4 and clcd. It reuses the existing devicetree binding, while not using quite as many of its properties as the fbdev driver does (those are left for future work). v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks to DRM core's excellent new helpers. v3: Don't match pl110 any more, don't attach if we don't have a DRM panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple display helper, use drm_gem_cma_dumb_create (same as our wrapper). v4: Change the driver's .name to not clash with fbdev in sysfs, drop platform alias, drop redundant "drm" in DRM driver name, hook up .prepare_fb to the CMA helper so that DMA fences should work. v5: Move register definitions inside the driver directory, fix build in COMPILE_TEST and !AMBA mode. v6: Drop TIM2_CLKSEL for now to be consistent with existing DT bindings, switch back to external register definitions.
