drm/stm: ltdc: Remove unnecessary platform_get_resource() error check

2017-12-19T14:23:45+00:00

devm_ioremap_resource() already checks if the resource is NULL, so remove the unnecessary platform_get_resource() error check.

drm/stm: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:41+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. Remove duplicate ldev assignment.

drm/stm: ltdc: add a 2nd endpoint

2017-11-07T13:47:39+00:00

ltdc can have up to 2 endpoints: - dpi external gpios: for rgb panels or external bridge ICs. - dpi internal ios: connected internally to dsi. Note: Refer to the reference manual to know if the dsi is present on your device.

drm/stm: ltdc: remove bridge from driver internal structure

2017-10-10T09:32:48+00:00

With a call to drm_of_panel_bridge_remove() we could remove the bridge without store it in ldtc internal driver structure.

drm/stm: fix warning about multiplication in condition

2017-09-08T08:29:11+00:00

gcc-7 complains about multiplying within a condition being suspicious: drivers/gpu/drm/stm/dw_mipi_dsi-stm.c: In function 'dsi_pll_get_clkout_khz': drivers/gpu/drm/stm/dw_mipi_dsi-stm.c:117:10: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context] The code here is correct, but can be easily rephrased to make that more obvious. I also swap out the error handling and the normal code path for clarity.

drm_fb_cma_create() is just a wrapper around drm_gem_fb_create() now, so use the function directly.
