The fbdev framework doesn't care to call the .set_power callback only on changes. So the driver has to care for itself that the regulator doesn't get disabled more often than enabled. This fixes the regulator warning unbalanced disables for lcd supply which can be triggered by doing echo 4 > /sys/class/lcd/imxfb-lcd/lcd_power twice. Signed-off-by:

Add COMPILE_TEST support to controlfb driver for better compile testing coverage. While at it: - convert driver to use eieio() and dcbf() helpers instead of open-coding them - add invalid_vram_cache() helper to avoid code duplication Acked-by:

Use the atomic API wherever appropriate and get rid of pwm_apply_args() call (the reference period and polarity are now explicitly set when calling pwm_apply_state()). We also make use of the pwm_set_relative_duty_cycle() helper to ease relative to absolute duty_cycle conversion. Signed-off-by:

drm_gem_fb_init() is passed the fb and never allocates it, so it should be not the one freeing it. As it is now the second call to kfree() is possible with the same fb. Coverity reported the following: *** CID 1492613: Memory - corruptions (USE_AFTER_FREE) /drivers/gpu/drm/drm_gem_framebuffer_helper.c: 230 in drm_gem_fb_create_with_funcs() 224 fb = kzalloc(sizeof(*fb), GFP_KERNEL); 225 if (!fb) 226 return ERR_PTR(-ENOMEM); 227 228 ret = drm_gem_fb_init_with_funcs(dev, fb, file, mode_cmd, funcs); 229 if (ret) { vvv CID 1492613: Memory - corruptions (USE_AFTER_FREE) vvv Calling "kfree" frees pointer "fb" which has already been freed.

The txt binding specified the property "power-supply". But the example and the actual implementation in the linux-kernel uses "avdd-supply". So the binding is adjusted to use avdd-supply as this seems to be the correct choice. There are no DT files in the linux kernel to check. Signed-off-by:
