The hdmi4.c and hdmi5.c files include the legacy GPIO header <linux/gpio.h> but does not use any of the symbols from this file. What it does use is the implicit inclusion of <linux/of.h> leading to compile errors if we just drop this include. Include the right header. Cc: Tony Lindgren <tony@atomide.com> Signed-off-by:

This patch adds support for G200 desktop cards. We can reuse the whole memory and modesetting code. A few PCI and DAC register values have to be updated accordingly. The most significant change is in the PLL setup. The driver parses the device's BIOS to retrieve clock limits and reference clocks. With no BIOS found, safe defaults are being used. v2: * copy BIOS ROM to system memory and access with regular load/store; resolves potential HW limitations * fix some stray whitespaces Signed-off-by:

MGA cards can run in traditional VGA mode or an enhanced MGA mode; with the latter being required for KMS. So far, MGA mode was enabled during modesetting. As it's fundamental for device operation, the patch moves it next to the device register setup. Signed-off-by:

Thomas Zimmermann authored
So far, PCI option registers were initialized as part of modesetting, which is late in the process. As these registers control fundamental operation, they should be set early. The patch moves the PCI option handling into device register setup, before even the device MMIO memory is being mapped. No functional changes made. Moving the PCI code next to the device-register setup also allows to remove the has_sdram field from struct mga_device. The state is now local to the init helper. Signed-off-by:

The mgag200 driver maps registers into the address space. Move the code into a separate helper function. No functional changes. One small difference is in the handling of SDRAM/SGRAM. MGA devices can come with either SDRAM or SGRAM. So far, the driver checked for SDRAM, which is the common case. The patch moves this code into a separate helper and checks for SGRAM, which is the special case. The test itself is the same as before. Signed-off-by:

SHMEM pages use write-combine caching by default, but can also use the platform's default page caching. Doing so may improve the performance of I/O on the framebuffer. Mgag200's hardware does not access framebuffer pages directly (i.e., via DMA), so enabling caching does not have an effect on consistency of the framebuffer memory or the displayed data.

The ast driver's load and unload functions are left-overs from when struct drm_driver.load/unload was still in use. The PCI probe helper allocated the DRM device and ran load to initialize it. This patch replaces this code with device create and destroy. The main difference is that the device's create function allocates the DRM device and ast structures in the same place. This will be required for switching ast to managed allocations. Signed-off-by:

Userspace can provoke this, we generally don't allow userspace to spam dmesg. Tune it down to debug. Unfortunately we don't have easy access to the drm_device here (not at all without changing a few things), so leave it as old style dmesg output for now.

When configuring the IPU for packed YUV 4:2:2, depending on the scaling ratios given by the source and destination resolutions, it is possible to crash the IPU block, to the point where a software reset of the IP does not fix it. This can happen anytime, in the first few frames, or after dozens of minutes. The same crash also happens when the IPU is fully controlled by the LCD controller (in that case no HW register is written at any moment after startup), which points towards a hardware bug. Thanksfully multiplanar YUV is not affected. Until this bug is fixed or worked around, address this issue by removing support for YUV 4:2:2 on the IPU of the JZ4725B. v2: Update commit message (remove the "crash beyond repair" bit) Reviewed-by:

On older SoCs, it is necessary to restart manually the IPU when a frame is done processing. Doing so on newer SoCs (JZ4760/70) kinds of work too, until the input or output resolutions or the framerate are too high. Make it work properly on newer SoCs by letting the LCD controller trigger the IPU frame restart signal. Reviewed-by:
