drm/msm: basic KMS driver for snapdragon
The snapdragon chips have multiple different display controllers,
depending on which chip variant/version. (As far as I can tell, current
devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And
then external to the display controller are HDMI, DSI, etc. blocks which
may be shared across devices which have different display controller
blocks.
To more easily add support for different display controller blocks, the
display controller specific bits are split out into a "kms" module,
which provides the kms plane/crtc/encoder objects.
The external HDMI, DSI, etc. blocks are part encoder, and part connector
currently. But I think I will pull in the drm_bridge patches from
chromeos tree, and split them into a bridge+connector, with the
registers that need to be set in modeset handled by the bridge. This
would remove the 'msm_connector' base class. But some things need to be
double checked to make sure I could get the correct ON/OFF sequencing..
This patch adds support for mdp4 crtc (including hw cursor), dtv encoder
(part of MDP4 block), and hdmi.

chromeos tree, and split them into a bridge+connector, with the
registers that need to be set in modeset handled by the bridge. This
would remove the 'msm_connector' base class. But some things need to be
double checked to make sure I could get the correct ON/OFF sequencing..
This patch adds support for mdp4 crtc (including hw cursor), dtv encoder
(part of MDP4 block), and hdmi.

drm/msm: basic KMS driver for snapdragon
The snapdragon chips have multiple different display controllers,
depending on which chip variant/version. (As far as I can tell, current
devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And
then external to the display controller are HDMI, DSI, etc. blocks which
may be shared across devices which have different display controller
blocks.
To more easily add support for different display controller blocks, the
display controller specific bits are split out into a "kms" module,
which provides the kms plane/crtc/encoder objects.
The external HDMI, DSI, etc. blocks are part encoder, and part connector
currently. But I think I will pull in the drm_bridge patches from
chromeos tree, and split them into a bridge+connector, with the
registers that need to be set in modeset handled by the bridge. This

This patch adds support for mdp4 crtc (including hw cursor), dtv encoder

drm/msm/mdp5: Create a separate MDP5 device
In order to have a tree-like device hierarchy between MDSS and its
sub-blocks (MDP5, DSI, HDMI, eDP etc), we need to create a separate
device/driver for MDP5. Currently, MDP5 and MDSS are squashed
together are are tied to the top level platform_device, which is
also the one used to create drm_device.
The mdp5_kms_init code is split into two parts. The part where device
resources are allocated are associated with the MDP5 driver's probe,
the rest is executed later when we initialize modeset.
With this change, unlike MDP4, the MDP5 platform_device isn't tied to
the top level drm_device anymore. The top level drm_device is now
associated with a platform device that corresponds to MDSS wrapper
hardware.
Create mdp5_init/destroy funcs that will be used by the MDP5 driver
probe/remove. Use the HW_VERSION register in the MDP5 register address
space. Both the MDSS and MDP VERSION registers give out identical
version info.
The older mdp5_kms_init code is left as is for now, this would be removed
later when we have all the pieces to support the new device hierarchy.
