drm/tilcdc: Convert to Linux IRQ interfaces

2021-08-10T18:13:53+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. DRM IRQ callbacks are now being called directly or inlined. Calls to platform_get_irq() can fail with a negative errno code. Abort initialization in this case. The DRM IRQ midlayer does not handle this case correctly. For most drivers, only the DRM IRQ helpers use irq_enabled from struct drm_device. Tilcdc also uses irq_enabled to make its error rollback work correctly. As the field will become legacy, duplicated the state in the driver's local private structure.

drm/tilcdc: Remove tilcdc_crtc_max_width(), use private data

2020-10-10T17:02:14+00:00

We already have a private data member for maximum display width so let's use it and get rid of the redundant tilcdc_crtc_max_width(). The LCDC version probing is moved to before reading the device tree properties so that the version information is available when private data maximum width is initialized, if "max-width" property is not found.

drm/tilcdc: Remove obsolete crtc_mode_valid() hack

2019-08-02T13:00:42+00:00

Earlier there were no mode_valid() helper for crtc and tilcdc had a hack to over come this limitation. But now the mode_valid() helper is there (has been since v4.13), so it is about time to get rid of that hack.

drm/tilcdc: drop use of drmP.h

2019-07-17T10:52:55+00:00

Dropped drmP.h and all other header files not used by tilcdc_drv.h. Added the minimal includes and forwards to make the header file self-contained. Then dropped the remaining uses of drmP.h and fixed all fall-out.

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

drm/tilcdc: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:42+00:00

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly.

drm/tilcdc: Remove tilcdc_debugfs_cleanup()

2017-01-27T14:27:45+00:00

drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so the drm_driver.debugfs_cleanup callback is not needed. Also remove the unused tilcdc_module_ops.debugfs_cleanup() callback. drm_debugfs_cleanup() removes all debugfs files using debugfs_remove_recursive(), so there should be no need for such a callback in the future.
