On Amlogic G12A SoC, the 2,97GHz PLL frequency is not stable enough to provide a correct 297MHz pixel clock, so switch the PLL base frequency with a /2 OD when the 297MHz pixel clock is requested. This solves the issue on G12A and also works fine on GXBB, GXL & GXM. Signed-off-by:

The Amlogic G12A VPU is very similar to the Amlogic GXM VPU but with : - an enhanced plane blender, with up to 3 OSD planes - support for AFBC 1.2 decoder (for Bifrost GPU) - support display mode up to 4k60@75Hz Signed-off-by:

Add the bindings for the Bifrost family of ARM Mali GPUs. The Bifrost GPU architecture is similar to the Midgard family, but with a different Shader Core & Execution Engine structures. Bindings are based on the Midgard family bindings, but the inner architectural changes makes it a separate family needing separate bindings. The Bifrost GPUs are present in a number of recent SoCs, like the Amlogic G12A Family, and many other vendors. The Amlogic vendor specific compatible is added to handle the specific IP integration differences and dependencies. Signed-off-by:

Time to kill some bad sample code people are copying from ;) This is a complete rewrite of the cirrus driver. The cirrus_mode_set() function is pretty much the only function which is carried over largely unmodified. Everything else is upside down. It is a single monster patch. But given that it does some pretty fundamental changes to the drivers workflow and also reduces the code size by roughly 70% I think it'll still be alot easier to review than a longish baby-step patch series. Changes summary: - Given the small amout of video memory (4 MB) the cirrus device has the rewritten driver doesn't try to manage buffers there. Instead it will blit (memcpy) the active framebuffer to video memory. - All gem objects are stored in main memory and are manged using the new shmem helpers. ttm is out. - It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24 or RG16 at blit time if needed, to avoid the pitch becoming larger than what the cirrus hardware can handle. - The simple display pipeline is used. - The generic fbdev emulation is used. - It's a atomic driver now. - It runs wayland.

One might want to use the VC4 display stack without using Mesa. Similar to the debugfs fixes for not having all of the possible display bits enabled, make sure you can't oops in vc4 if v3d isn't enabled. v2: Fix matching against other v3d variants (review by Paul), don't forget to set irq_enabled so that the vblank uapi works v3: Use -ENODEV instead of -EINVAL on Paul's suggestion.

The global list of all debugfs entries for the driver was painful: the list couldn't see into the components' structs, so each component had its own debugs show function to find the component, then find the regset and dump it. The components also had to be careful to check that they were actually registered in vc4 before dereferencing themselves, in case they weren't probed on a particular platform. They routinely failed at that. Instead, we can have the components add their debugfs callbacks to a little list in vc4 to be registered at drm_dev_register() time, which gets vc4_debugfs.c out of the business of knowing the whole list of components. Thanks to this change, dsi0 (if it existed) would register its node. v2: Rebase on hvs_underrun addition. v3: whitespace fixup Signed-off-by:

Support Rocktech jh057n00900 5.5" 720x1440 TFT LCD panel. It is a MIPI DSI video mode panel. The panel seems to use a Sitronix ST7703 look alike (most of the commands look similar to the ST7703's data sheet but use a different number of parameters). The initial version of the DSI init sequence (including sleeps) were provided by the vendor. Sleeps were reduced considerably though to speed up initialization. Signed-off-by:

Interpreting it as a 0.16 fixed point means we can't accurately represent 1.0. Which is one of the values we really should be able to represent. Since most (all?) luts have lower precision this will only affect rounding of 0xffff.
