This panel is quite similar to the similarly named N116BGE panel (the nominal timings are, in fact identical). However, let's add a new entry because the full range of clocks listed for N116BGE aren't supported for N116BCA-EA1, at least according to the datasheet. Signed-off-by:

On an Innolux N116BCA panel that I have in front of me, sometimes HPD simply doesn't assert no matter how long you wait for it. As per the very wise advice of The IT Crowd ("Have you tried turning it off and on again?") it appears that power cycling is enough to kick this panel back into a sane state. >From tests on this panel, it appears that leaving it powered off for a while stimulates the problem. Adding a 6 second sleep at the start of panel_simple_prepare_once() makes it happen fairly reliably and, with this delay, I saw up to 3 retries needed sometimes. Without the 6 second sleep, however, the panel came up much more reliably the first time or after only 1 retry. While it's unknown what the problems are with this panel (and probably the hardware should be debugged), adding a few retries to the power on routine doesn't seem insane. Even if this panel's problems are attributed to the fact that it's pre-production and/or can be fixed, retries clearly can help in some cases and really don't hurt. Signed-off-by: -

If a panel has an hpd_absent_delay specified then we know exactly how long the maximum time is before HPD must be asserted. That means we can use it as a timeout for polling the HPD pin instead of using an arbitrary timeout. This is especially useful for dealing with panels that periodically fail to power on and need to be retried. We can detect the problem sooner. Signed-off-by:

If the HPD signal never asserts in panel_simple_prepare() and we return an error, we should unset the enable GPIO and disable the regulator to make it consistent for the caller. At the moment I have some hardware where HPD sometimes doesn't assert. Obviously that needs to be debugged, but this patch makes it so that if I add a retry that I can make things work.

Even though the JZ4740 did not have the OSD mode, it had (according to the documentation) two DMA channels, but there is absolutely no information about how to select the second DMA channel. Make the ingenic-drm driver work in non-OSD mode by using the foreground0 plane (which is bound to the DMA0 channel) as the primary plane, instead of the foreground1 plane, which is the primary plane when in OSD mode.

A recent patch renaming MIPI_DSI_MODE_EOT_PACKET to MIPI_DSI_MODE_NO_EOT_PACKET brought to light the misunderstanding in the current MCDE driver and all its associated panel drivers that MIPI_DSI_MODE_EOT_PACKET would mean "use EOT packet" when in fact it means the reverse. Fix it up by implementing the flag right in the MCDE DSI driver and remove the flag from panels that actually want the EOT packet. Suggested-by:

By having selected DRM_XEN, I was assuming I would build the frontend driver. As it turns out this is a dummy option, and I have really not been building this (because I had DRM disabled). Make it a promptless one, moving the "depends on" to the other, real option, and "select"ing the dummy one. Signed-off-by:

Some of them have gaps, or fields we don't clear. Native ioctl code does full copies plus zero-extends on size mismatch, so nothing can leak. But compat is more hand-rolled so need to be careful. None of these matter for performance, so just memset. Also I didn't fix up the CONFIG_DRM_LEGACY or CONFIG_DRM_AGP ioctl, those are security holes anyway. Acked-by:

By default dma_buf_export() sets the exporter name to be KBUILD_MODNAME. Unfortunately this may not be identical to the string used as the heap name (ie: "system" vs "system_heap"). This can cause some minor confusion with tooling, and there is the future potential where multiple heap types may be exported by the same module (but would all have the same name). So to avoid all this, set the exporter exp_name to the heap name.
