2019-05-16drm/sun4i: sun6i_mipi_dsi: Fix hsync_porch overflowJagan Teki
Loop N1 instruction delay for burst mode devices are computed based on horizontal sync and porch timing values. The current driver is using u16 type for computing this hsync_porch value, which would failed to fit within the u16 type for large sync and porch timings devices. This would result in hsync_porch overflow and eventually computed wrong instruction delay value. Example, timings, where it produces the overflow { .hdisplay = 1080, .hsync_start = 1080 + 408, .hsync_end = 1080 + 408 + 4, .htotal = 1080 + 408 + 4 + 38, } It reproduces the desired delay value 65487 but the correct working value should be 7. So, Fix it by computing hsync_porch value separately with u32 type.

2019-05-16drm/sun4i: Fix sun8i HDMI PHY clock initializationJernej Skrabec
Current code initializes HDMI PHY clock driver before reset line is deasserted and clocks enabled. Because of that, initial readout of clock divider is incorrect (0 instead of 2). This causes any clock rate with divider 1 (register value 0) to be set incorrectly. Fix this by moving initialization of HDMI PHY clock driver after reset line is deasserted and clocks enabled.

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging.

2019-03-07drm/sun4i: rgb: Change the pixel clock validation checkMaxime Ripard
The current code, since commit bb43d40d7c83 ("drm/sun4i: rgb: Validate the clock rate"), perform some validation on the pixel clock to filter out the EDID modes provided by monitors (through bridges) that we wouldn't be able to reach. For the usual modes, we're able to generate a perfect clock rate, so a strict check was enough. However, this had the side effect of preventing displays that would work otherwise to operate properly, since we would pretty much never be able to generate an exact rate for those displays, even though we would fall within that panel tolerance. This was also shown to happen for unusual modes exposed through EDIDs, for example on eDP panels. We can work around this by simplifying a bit the problem: no panels we've encountered so far actually needed that check. All of them are tied to a particular board when it is produced, and made to work with the Allwinner BSP. That pretty much guarantees that we never have a pixel clock out of reach. On the other hand, the EDIDs modes that needed to be validated have always been exposed through bridges. Let's just use that metric to instead of validating all modes, only validate modes when we have a bridge attached. It should be good enough for now, while we still have room for improvements or refinements using the display_timings structure for example for panels. We also add a tolerance for EDID-based modes instead of doing a strict check. This tolerance is of 0.5% which is the one advertised in the VESA DVT and CVT specs. If that needed to be extended in the future, we can add a custom module parameter to relax it a bit.

2019-02-19drm/sun4i: dsi: Change the start delay calculationMaxime Ripard
The current calculation for the video start delay in the current DSI driver is that it is the total vertical size, minus the front porch and sync length, plus 1. This equals to the active vertical size plus the back porch plus 1. That 1 is coming in the Allwinner BSP from an variable that is set to 1. However, if we look at the Allwinner BSP more closely, and especially in the "legacy" code for the display (in drivers/video/sunxi/legacy/), we can see that this variable is actually computed from the porches and the sync minus 10, clamped between 8 and 100. This fixes the start delay symptom we've seen on some panels (vblank timeouts with vertical white stripes at the bottom of the panel).

2019-02-01drm/sun4i: tcon: Prepare and enable TCON channel 0 clock at initPaul Kocialkowski
When initializing clocks, a reference to the TCON channel 0 clock is obtained. However, the clock is never prepared and enabled later. Switching from simplefb to DRM actually disables the clock (that was usually configured by U-Boot) because of that. On the V3s, this results in a hang when writing to some mixer registers when switching over to DRM from simplefb. Fix this by preparing and enabling the clock when initializing other clocks. Waiting for sun4i_tcon_channel_enable to enable the clock is apparently too late and results in the same mixer register access hang.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
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.

2019-01-22drm/sun4i: hdmi: Fix usage of TMDS clockPriit Laes
Although TMDS clock is required for HDMI to properly function, nobody called clk_prepare_enable(). This fixes reference counting issues and makes sure clock is running when it needs to be running. Due to TDMS clock being parent clock for DDC clock, TDMS clock was turned on/off for each EDID probe, causing spurious failures for certain HDMI/DVI screens.

2019-01-18drm/sun4i: frontend: Hook-in support for the A20Paul Kocialkowski
This adds the appropriate device-tree compatible for hooking frontend support for the A20. Since the hardware is very similar to the A10, it shares the same quirks (which were already introduced).
