This updates the compatible string for a no-name LCD panel to "vot,v220hf01a-t", "ilitek,ili9225". The original bindings were the generic "ilitek,ili9225-2.2in-176x220" because I could not find a datasheet. However, after some more research, I finally found one, so the actual vendor and model name are now known. This previous bindings have not made it to the mainline kernel yet, so this is not breaking backwards compatibility. Signed-off-by:

This adds support for the Ilitek ILI9322 QVGA (320x240) TFT panel driver. This panel driver supports serial or parallel RGB or YUV input and also ITU-T BT.656 input streams. The controller is combined with a physical panel and configured through the device tree.

Add helper for initializing fbdev deferred I/O. The cleanup could have happened in drm_fb_helper_fini(), but that would have required me to set fb_info->fbdefio to NULL in a couple of drivers before they call _fini() to avoid double defio cleanup. The problem is that one of those is vboxvideo which lives in Greg's staging tree. So I put the cleanup in drm_fb_helper_fbdev_teardown(), not perfect but not that bad either. Signed-off-by:

We don't want people to accidentally stumble over there. Also rename the plane helpers to legacy plane helpers. After Ville's patch to make the clipping helper atomic and move it to drm_atomic_helper.c there's nothing left in there that should be useful for modern drivers. v2: Laurent had a few questions around how state is added to drm_atomic_state, tried to clarify that. And spotted another sentence where the docs suggested subclassing. v3: Small polish (Alex). Reviewed-by:

DK put some nice docs into the commit introducing driver private state, but in the git history alone it'll be lost. Also, since Ville remove the void* usage it's a good opportunity to give the driver private stuff some tlc on the doc front. Finally try to explain why the "let's just subclass drm_atomic_state" approach wasn't the greatest, and annotate all those functions as deprecated in favour of more standardized driver private states. Also note where we could/should extend driver private states going forward (atm neither locking nor synchronization is handled in core/helpers, which isn't really all that great). v2: Spelling and phrasing improvements (Alex, DK).

It thinks we want to document the __printf(2,0) annotion. Not sure we want to teach it about all possible gcc-only flags, hence why I opted for the cheap trick of just moving it ahead of the kerneldoc. This is only a problem for static inline functions, since for non-inline function the kerneldoc is in the .c file, but the special annotations are all in the header.

Also some breadcrumbs for how exactly to find this. Probably should pass drm_connector * or at least drm_display_info * to that function instead. But drm_hdmi_avi_infoframe_quant_range probably also wants drm_connector_state (and the hdmi stuff moved into that), so this is a bit more work. v2: Fix typo (Alex).

kerneldoc for drm_plane_create_zpos_property() says that the DRM core will automatically calculate the normalized zpos values, but it doesn't actually do that anymore since commit 38d868e4 ("drm: Don't force all planes to be added to the state due to zpos"). Instead, drivers are supposed to explicitly call the drm_atomic_normalize_zpos() function. Change the kerneldoc comment to reflect that. v2: reference the commit that introduced the kerneldoc unclarity Reviewed-by:

There are a set of values in the drm_display_info structure for each connector which hold information derived from EDID. These are computed in drm_add_display_info. Before this patch, that was only called in drm_add_edid_modes. This meant that they were only set when EDID was present and never reset when EDID was not, as happened when the display was disconnected. One of these fields, non_desktop, is used from drm_mode_connector_update_edid_property, the function responsible for assigning the new edid value to the application-visible property. Various drivers call these two functions (drm_add_edid_modes and drm_mode_connector_update_edid_property) in different orders. This means that even when EDID is present, the drm_display_info fields may not have been computed at the time that drm_mode_connector_update_edid_property used the non_desktop value to set the non_desktop property. I've added a public function (drm_reset_display_info) that resets the drm_display_info field values to default values and then made the drm_add_display_info function public. These two functions are now called directly from drm_mode_connector_update_edid_property so that the drm_display_info fields are always computed from the current EDID information before being used in that function. This means that the drm_display_info values are often computed twice, once when the EDID property it set and a second time when EDID is used to compute modes for the device. The alternative would be to uniformly ensure that the values were computed once before being used, which would require that all drivers reliably invoke the two paths in the same order. The computation is inexpensive enough that it seems more maintainable in the long term to simply compute them in both paths. The API to drm_add_display_info has been changed so that it no longer takes the set of edid-based quirks as a parameter. Rather, it now computes those quirks itself and returns them for further use by drm_add_edid_modes. This patch also includes a number of 'const' additions caused by drm_mode_connector_update_edid_property taking a 'const struct edid *' parameter and wanting to pass that along to drm_add_display_info. v2: after review by Daniel Vetter <daniel.vetter@ffwll.ch> Removed EXPORT_SYMBOL_GPL for drm_reset_display_info and drm_add_display_info. Added FIXME in drm_mode_connector_update_edid_property about potentially merging that with drm_add_edid_modes to avoid the need for two driver calls. Signed-off-by:
