MIPI_SEQ_ASSERT_RESET before POWER_ON is not necessary for 2 reasons: 1) The reset should already be asserted before intel_dsi_pre_enable() gets called 2) Most (some?) VBTs will ensure reset was asserted in their MIPI_SEQ_DEASSERT_RESET themselves Signed-off-by: Hans de Goede <hdegoede@xxxxxxxxxx> --- drivers/gpu/drm/i915/intel_dsi.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_dsi.c b/drivers/gpu/drm/i915/intel_dsi.c index 78d5884..4ebf308 100644 --- a/drivers/gpu/drm/i915/intel_dsi.c +++ b/drivers/gpu/drm/i915/intel_dsi.c @@ -669,7 +669,6 @@ static void intel_dsi_pre_enable(struct intel_encoder *encoder, /* put device in ready state */ intel_dsi_device_ready(encoder); - intel_dsi_exec_vbt_sequence(intel_dsi, MIPI_SEQ_ASSERT_RESET); intel_dsi_exec_vbt_sequence(intel_dsi, MIPI_SEQ_POWER_ON); intel_dsi_exec_vbt_sequence(intel_dsi, MIPI_SEQ_DEASSERT_RESET); intel_dsi_exec_vbt_sequence(intel_dsi, MIPI_SEQ_INIT_OTP); -- 2.9.3 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
