2016-11-04drm: mali-dp: Add pitch alignment check for planesBrian Starkey1-1/+14
Check that the framebuffer pitches are appropriately aligned when checking planes. Signed-off-by: Brian Starkey <[email protected]> Signed-off-by: Liviu Dudau <[email protected]>
2016-11-04drm: mali-dp: Add pitch alignment check functionBrian Starkey2-0/+12
Different hardware versions have different requirements when it comes to pitch alignment. Add a function which can be used to check pitch alignment for a device. Signed-off-by: Brian Starkey <[email protected]> Signed-off-by: Liviu Dudau <[email protected]>
2016-11-02drm: mali-dp: Set the drm->irq_enabled flag to match driver's state.Liviu Dudau1-0/+3
Mali DP driver does not use drm_irq_{un,}install() function so the drm->irq_enabled flag does not get set automatically. drm_wait_vblank() checks the value of the flag among other functions. Signed-off-by: Liviu Dudau <[email protected]>
2016-11-02drm: mali-dp: Clear the config_valid flag before using it in wait_event.Liviu Dudau1-0/+1
config_valid variable is used to signal the activation of the CVAL request when the vsync interrupt has fired. malidp_set_and_wait_config_valid() uses the variable in wait_event_interruptible_timeout without clearing it first, so the wait is skipped. Signed-off-by: Liviu Dudau <[email protected]>

2016-10-31drm/i2c: tda998x: mali-dp: hdlcd: refactor connector registrationBrian Starkey2-15/+22
Connectors shouldn't be registered until the rest of the whole device is set up, so that consistent state is presented to userspace. As such, remove the calls to drm_connector_register() and drm_connector_unregister() from tda998x, as these are now handled by drm_dev_(un)register() itself. To work with this change, the mali-dp and hdlcd bind and unbind sequences have to be reordered, to ensure that the componentised encoder/connector is bound before drm_dev_register() registers all connectors. Similarly, the device must be unregistered before the component is unbound. Altogether, this allows other drivers using tda998x to be de-midlayered, and to have less racy initialisation of their components. Splitting this commit into three (one per driver) isn't possible without intermediate breakage, so it is all squashed together here.

2016-08-29drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commitLiu Ying1-1/+2
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

2016-06-02drm: hdlcd: Revamp runtime power managementLiviu Dudau3-35/+39
Because the HDLCD driver acts as a component master it can end up enabling the runtime PM functionality before the encoders are initialised. This can cause crashes if the component slave never probes (missing module) or if the PM operations kick in before the probe finishes. Move the enabling of the runtime PM after the component master has finished collecting the slave components and use the DRM atomic helpers to suspend and resume the device.

This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes <[email protected]> Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.
