Allocate DSI host structure for each DSI port available on gen11 and register them with DSI fwk of DRM. Some of the DSI host operations are also registered as part of this. Retrieves DSI pkt (from DSI msg) to be sent over DSI link using DRM DSI exported functions. A wrapper function is also added as "DSI host transfer" for sending DSI data/cmd. Add DSI packet payload to command payload queue using credit based mechanism for *long* packets. v2 by Jani: - indentation - Use the new credit available helper - Use int for free_credits - Add intel_dsi local variable for better code flow - Use the new credit available helper - Use int for free_credits, i, and j v3 by Jani: - Squash DSI host allocation and transfer patches together Signed-off-by: Madhav Chauhan <madhav.chauhan@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/af4f168ed8737d44687d8b6f21ecaa7e805eb695.1543500286.git.jani.nikula@intel.com

2018-12-03drm/i915/icl: Use the same pll functions for dsiVandita Kulkarni
The same pll manager functions can be used to enable dpll for mipi. Hence enabling the IO power and esc clock as part of pre pll enable call. v2 by Jani: - fix function parameter indent (Madhav) Signed-off-by: Vandita Kulkarni <vandita.kulkarni@intel.com> Reviewed-by: Madhav Chauhan <madhav.chauhan@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/07db5b1ce59c00295fad8a8e81908d59d8d76915.1543500286.git.jani.nikula@intel.com
2018-12-03drm/i915/icl: Allocate DSI encoder/connectorMadhav Chauhan
This patch allocates memory for DSI encoder and connector which will be used for various DSI encoder/connector operations and attaching the same to DRM subsystem. This patch also extracts DSI modes info from VBT and save the desired mode info to connector. v2 by Jani: - Drop GEN11 prefix from encoder name - Drop extra parenthesis - Drop extra local variable - Squash encoder power domain here v3 by Jani: - Squash connector and connector helper functions here - Move intel_dsi_vbt_init call here Signed-off-by: Madhav Chauhan <madhav.chauhan@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/0197023b92ffa2d59064e30fd4ca22b6a4cff16c.1543500286.git.jani.nikula@intel.com
