drm/tinydrm: Fix fbdev pixel format

2019-04-11T14:16:06Z

Due to copy/paste error, the fbdev format was changed to 32bpp = XRGB8888 which is an emulated format for the RGB565 drivers. Revert to to using the fallback which is dev->mode_config.preferred_depth for the drivers that set it or 32bpp for those that don't (repaper, st7586).

drm/tinydrm: Use drm_dev_enter/exit()

2019-03-04T14:32:21Z

This protects device resources from use after device removal. There are 3 ways for driver-device unbinding to happen: - The driver module is unloaded causing the driver to be unregistered. This can't happen as long as there are open file handles because a reference is taken on the module. - The device is removed (Device Tree overlay unloading). This can happen at any time. - The driver sysfs unbind file can be used to unbind the driver from the device. This can happen any time. v2: Since drm_atomic_helper_shutdown() has to be called after drm_dev_unplug() we don't want do block ->disable after unplug.

drm/tinydrm: Remove tinydrm_shutdown()

It's just a wrapper around drm_atomic_helper_shutdown() now. Also store drm_device in the drvdata field, since that's what's used. Signed-off-by: Noralf Trønnes Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20190210131039.52664-7-noralf@tronnes.org

drm/tinydrm: Use damage helper for dirtyfb

2019-01-17T09:57:15Z

This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty handler. All flushing will now happen in the pipe functions. Also enable the damage plane property for all except repaper which can only do full updates. ili9225: This change made ili9225_init() equal to mipi_dbi_init() so use it. v3: Include vblank header (Sam) ili9225 and st7586 can't use mipi_dbi_enable_flush() (David) v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL (kbuild test robot) Cc: David Lechner Cc: Eric Anholt Signed-off-by: Noralf Trønnes Acked-by: Daniel Vetter Reviewed-by: Sam Ravnborg Tested-by: David Lechner Reviewed-by: David Lechner Link: https://patchwork.freedesktop.org/patch/msgid/20190115043643.2364-5-noralf@tronnes.org

drm/tinydrm: Use struct drm_rect

2019-01-17T09:57:03Z

This prepares for the switch to drm_atomic_helper_dirtyfb() in the next patch. The damage helper returns a drm_rect so switch to that everywhere including using a pointer in the dirty functions. This is a non-functional change except for the debug print which looks a bit different.
