Instead use a boolean field in the memory manager structure. Also invert the meaning of the field since the use of a TT structure is the special case here. v2: cleanup zero init. Signed-off-by:

Instead of keeping the IPU clock enabled constantly, enable and disable it on demand, when the IPU plane is used. That way, we won't use any extra power when the IPU is not used. v2: Explain the reason of this patch Reviewed-by:

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:

The mxsfb_set_pixel_fmt() and mxsfb_set_bus_fmt() functions both deal with format configuration, are always called in a row from mxsfb_crtc_mode_set_nofb(), and set fields from the LCDC_CTRL register. This requires a read-modify-update cycle in mxsfb_set_bus_fmt(). Make this more efficient by merging them together. Signed-off-by:

Enable vblank handling when the CRTC is turned on and disable it when it is turned off. This requires moving vblank init after the KMS pipeline initialisation, otherwise drm_vblank_init() gets called with 0 CRTCs. Signed-off-by:

The driver attempts agressive power management by enabling and disabling the AXI clock around register accesses. This results in attempts to enable and disable the clock in the IRQ handler, which is a no-go as preparing or unpreparing the clock may sleep. On the other hand, the driver enables the AXI clock when enabling the CRTC and keeps it enabled until the CRTC is disabled. This is correct, and renders the power management attempt pointless, as interrupts are not supposed to occur when the CRTC is off. The same reasoning can be applied to the CRTC .enable_vblank() and .disable_vblank() that are not supposed to be called when the CRTC off and thus don't require manual handling of the AXI clock. Furthermore, vblank handling is never enabled, which results in the vblank enable and disable handlers never being called. To fix this, remove the manual clock handling in the IRQ, the CRTC .enable_vblank() and .disable_vblank() handlers and the plane .atomic_update() handler. We however need to handle the clock manually in mxsfb_irq_disable() as is calls .disable_vblank() manually and is used both at probe and remove time. The clock disabling is also moved to the last step of the mxsfb_crtc_atomic_disable() function, to prepare for enabling vblank handling. Signed-off-by:

The vblank event is armed in the plane .atomic_update(). This works fine as we have a single plane, and was the only option when the driver was using the drm_simple_kms_helper helper, but will break as soon as multiple planes are supported. Move it to CRTC .atomic_flush(). Signed-off-by:

Replace the manual connector implementation based on drm_panel with the drm_panel_bridge helper. This simplifies the mxsfb driver by removing connector-related code, and standardizing all pipeline control operations on bridges. A hack is needed to get hold of the connector, as that's our only source of bus flags and formats for now. As soon as the bridge API provides us with that information this can be fixed.
