drm/shmobile: Make use of the helper function devm_platform_ioremap_resource()

2021-10-07T02:42:18+00:00

Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing Reviewed-by: Kieran Bingham Reviewed-by: Laurent Pinchart Signed-off-by: Laurent Pinchart

drm/shmobile: Convert to Linux IRQ interfaces

2021-07-25T09:01:12+00:00

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers don't benefit from using it. v3: * return error if (ret < 0) (Geert) * remove duplicate error message (Geert) v2: * handle errors in platform_get_irq() (Geert, Sergei) * store IRQ number in struct shmob_drm_device (Laurent) Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20210720080941.23646-1-tzimmermann@suse.de

drm/: Constify struct drm_driver

2020-11-06T09:31:26+00:00

Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg Cc: kernel test robot Acked-by: Maxime Ripard Reviewed-by: Alex Deucher Signed-off-by: Daniel Vetter Cc: Sam Ravnborg Cc: Dave Airlie Cc: Gerd Hoffmann Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland Cc: Leo Li Cc: Alex Deucher Cc: Christian König Cc: Eric Anholt Cc: Maxime Ripard Cc: Ben Skeggs Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch

drm/shmobile: Set GEM CMA functions with DRM_GEM_CMA_DRIVER_OPS

2020-06-10T07:05:18+00:00

DRM_GEM_CMA_DRIVER_OPS sets the functions in struct drm_driver to their defaults. No functional changes are made. Signed-off-by: Thomas Zimmermann Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-33-tzimmermann@suse.de

drm/shmobile: Use GEM CMA object functions

2020-06-10T07:05:12+00:00

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which allocates the object and sets CMA's default object functions. Corresponding callbacks in struct drm_driver are cleared. No functional changes are made. Driver and object-function instances use the same callback functions, with the exception of vunmap. The implementation of vunmap is empty and left out in CMA's default object functions. v3: * convert to DRIVER_OPS macro in a separate patch Signed-off-by: Thomas Zimmermann Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-32-tzimmermann@suse.de

drm/shmob: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:06:05+00:00

It's right above the drm_dev_put(). This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). Aside: Another driver with a bit much devm_kzalloc, which should probably use drmm_kzalloc instead ... v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas) Cc: Sam Ravnborg Cc: Thomas Zimmermann Reviewed-by: Laurent Pinchart (v2) Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Laurent Pinchart Cc: Kieran Bingham Cc: linux-renesas-soc@vger.kernel.org Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-40-daniel.vetter@ffwll.ch
