drm/tiny: correctly print `struct resource *` on error

2023-10-19T21:11:04+00:00

commit c1165df2be2fffe3adeeaa68f4ee4325108c5e4e upstream. The `res` variable is already a `struct resource *`, don't take the address of it. Fixes incorrect output: simple-framebuffer 9e20dc000.framebuffer: [drm] *ERROR* could not acquire memory range [??? 0xffff4be88a387d00-0xfffffefffde0a240 flags 0x0]: -16 To be correct: simple-framebuffer 9e20dc000.framebuffer: [drm] *ERROR* could not acquire memory range [mem 0x9e20dc000-0x9e307bfff flags 0x200]: -16 Signed-off-by: Joey Gouly Fixes: 9a10c7e6519b ("drm/simpledrm: Add support for system memory framebuffers") Cc: Thomas Zimmermann Cc: Thierry Reding Cc: Javier Martinez Canillas Cc: dri-devel@lists.freedesktop.org Cc: # v6.3+ Reviewed-by: Thomas Zimmermann Signed-off-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20231010174652.2439513-1-joey.gouly@arm.com Signed-off-by: Greg Kroah-Hartman

drm: gm12u320: Fix the timeout usage for usb_bulk_msg()

2023-09-23T09:14:31+00:00

[ Upstream commit 7583028d359db3cd0072badcc576b4f9455fd27a ] The timeout arg of usb_bulk_msg() is ms already, which has been converted to jiffies by msecs_to_jiffies() in usb_start_wait_urb(). So fix the usage by removing the redundant msecs_to_jiffies() in the macros. And as Hans suggested, also remove msecs_to_jiffies() for the IDLE_TIMEOUT macro to make it consistent here and so change IDLE_TIMEOUT to msecs_to_jiffies(IDLE_TIMEOUT) where it is used.

drm/repaper: Reduce temporary buffer size in repaper_fb_dirty()

[ Upstream commit fedf429e071f6dbbe7a69dfc342492e037692018 ] As the temporary buffer is no longer used to store 8-bit grayscale data, its size can be reduced to the size needed to store the monochrome bitmap data.

drm: Use of_property_read_bool() for boolean properties

2023-03-30T18:46:07+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to of_property_read_bool(). Reviewed-by: Laurent Pinchart Link: https://lore.kernel.org/r/20230310144706.1542295-1-robh@kernel.org Signed-off-by: Rob Herring

drm: Use of_property_present() for testing DT property presence

2023-03-28T19:55:33+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

drm/fbdev-generic: Remove unused prefer_shadow_fbdev flag

2023-03-22T12:32:47+00:00

Remove the flag prefer_shadow_fbdev from struct drm_mode_config. Drivers set this flag to enable shadow buffering in the generic fbdev emulation. Such shadow buffering is now mandatory, so the flag is unused.

drm/cirrus: Store HW format/pitch in primary-plane state

2023-03-13T09:37:05+00:00

The hardware settings for color format and pitch are state of the primary plane. Store the values in the primary plane's state structure struct cirrus_primary_plane_state. Adapt all callers. All fields in struct cirrus_device are now considered immutable after initialization. Plane updates consider the difference between the old and the new plane state before updating format or pitch.
