drm/stm: check pitch and size calculations even if !CONFIG_MMU

2018-02-23T08:37:12Z

In all cases we have to check pitch and size calculations to speed up data transfer.

drm/stm: drv: Improve data transfers

2018-01-30T10:45:15Z

To optimize data transfers, align pitch on 128 bytes & height on 4 bytes. This optimization is not applicable on hw without MMU.

drm/stm: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:41Z

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: Use drm_gem_fb_create()

2017-09-02T12:23:27Z

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

drm/stm: Use .dumb_map_offset and .dumb_destroy defaults

2017-07-29T11:57:51Z

This driver can use the drm_driver.dumb_destroy and drm_driver.dumb_map_offset defaults, so no need to set them.

drm/stm: drv: Rename platform driver name

2017-07-26T13:01:24Z

Rename the platform driver name from "stm" to "stm32-display" for a better readability in /sys/bus/platform/drivers entries. Note: We keep "stm" as drm_driver.name because it is better when using "modetest -M stm ..." (even if recent modetest patch avoids using -M).

drm/stm: Add STM32 LTDC driver

2017-04-14T18:30:29Z

This controller provides output signals to interface directly a variety of LCD and TFT panels. These output signals are: RGB signals (up to 24bpp), vertical & horizontal synchronisations, data enable and the pixel clock.
