| * | | | drm/msm/sde: allow mmus to be optional during kms initLloyd Atkinson2017-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix to avoid failing overall drm sde driver initialization in case one of the mmus expected is not defined by DTSI. Particular MMU support varies by platform and can be optional. Change-Id: I07162d1d064c9cc025ec494e83e1dfa7f14f65c1 Signed-off-by: Lloyd Atkinson <latkinso@codeaurora.org>

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix sde hw deconstruction which can be called twice back to back if hw initialization itself fails. In this case the catalog pointer will already be null, so we must check for it. Change-Id: Idc05efd7dd8c2a27f2c8128654e4c0b06697f39e Signed-off-by: Lloyd Atkinson <latkinso@codeaurora.org>
| * | | drm/msm/sde: parse csc type dtsi entry to select valid cscDhaval Patel2017-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | msm8998 supports 10bit csc while msm8996 supports csc only. This patch adds the dtsi entry to select the correct csc type while parsing hardware catalog to configure the valid csc hardware block.

| * | | drm/msm: fix copyright marking in "msm" drm driverDhaval Patel2017-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | msm driver is updated signficantly by CAF authors but it does not carry the CAF license. This patch update it accordingly. At the same time; kms, smmu, plane, crtc, encoder code was written by referring the mdp5 driver but it did not carry the license from mdp5 driver. The patch fixes the issue. Change-Id: I4670d2220d6df46213c7220a2b46de32e3ec15a5 Signed-off-by: Dhaval Patel <pdhaval@codeaurora.org>
