drm/tilcdc: tilcdc_panel: Rename device from "panel" to "tilcdc-panel"

2018-02-28T09:48:25+00:00

Rename the bundled tilcdc_panel driver from just "panel" to "tilcdc-panel" to avoid noisy error messages from the driver trying to probe all device nodes named "panel". Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen

drm/tilcdc: Add support for drm panels

2018-02-28T09:48:16+00:00

Add support for drm panels to tilcdc. Adding the support on top of the existing bridge support needs only couple of lines of code when using using the drm panel bridge helpers. Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen

drm/tilcdc: panel: Use common error handling code in of_get_panel_info()

2018-02-28T09:25:36+00:00

Add a jump target so that a bit of exception handling can be better reused at the end of this function. Signed-off-by: Markus Elfring Signed-off-by: Jyri Sarha

drm/tilcdc: Delete an error message for a failed memory allocation in seven functions

2018-02-28T09:25:35+00:00

Omit an extra message for a memory allocation failure in these functions. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Jyri Sarha

drm/tilcdc changes for 4.16 * tag 'tilcdc-4.16' of https://github.com/jsarha/linux: drm/tilcdc: make tilcdc_mode_hvtotal() static drm/tilcdc: Remove drm_framebuffer_get() and *_put() calls drm/tilcdc: ensure nonatomic iowrite64 is not used

drm/tilcdc: make tilcdc_mode_hvtotal() static

2017-12-18T20:29:21+00:00

The function tilcdc_mode_hvtotal is local to the source and does not need to be in global scope, so make it static. drivers/gpu/drm/tilcdc/tilcdc_crtc.c:297:6: warning: no previous prototype for 'tilcdc_mode_hvtotal' [-Wmissing-prototypes] uint tilcdc_mode_hvtotal(const struct drm_display_mode *mode) Signed-off-by: Xiongwei Song Signed-off-by: Jyri Sarha

drm/tilcdc: Remove drm_framebuffer_get() and *_put() calls

2017-12-18T11:24:30+00:00

The drm_framebuffer_get() and drm_framebuffer_put() calls in the tilcdc driver are obsolete. The drm atomic modesetting core should take care of holding the references while the atomic state object is in use. The old state is deleted when a commit of a new one is completed after drm_atomic_helper_wait_for_vblanks(). This also fixes an occasional framebuffer leak the old drm_framebuffer_get() and drm_framebuffer_put() code had. Signed-off-by: Jyri Sarha

drm/tilcdc: ensure nonatomic iowrite64 is not used

2017-12-18T11:24:29+00:00

Add a check to ensure iowrite64 is only used if it is atomic. It was decided in [1] that the tilcdc driver should not be using an atomic operation (so it was left out of this patchset). However, it turns out that through the drm code, a nonatomic header is actually included: include/linux/io-64-nonatomic-lo-hi.h is included from include/drm/drm_os_linux.h:9:0, from include/drm/drmP.h:74, from include/drm/drm_modeset_helper.h:26, from include/drm/drm_atomic_helper.h:33, from drivers/gpu/drm/tilcdc/tilcdc_crtc.c:19: And thus, without this change, this patchset would inadvertantly change the behaviour of the tilcdc driver.

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.
