From c6c30b917d40047cfd19f7a28a8eea7b6ddd6634 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Fri, 8 Mar 2019 13:43:00 -0800 Subject: [PATCH] drm/i915: Start using comparative INTEL_PCH_TYPE MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In order to make it easier to bring up new platforms without having to take care about all corner cases that was previously taken care for previous platforms we already use comparative INTEL_GEN statements. Let's start doing the same with PCH. The only caveats are: - less-than comparisons need to be avoided or done with attention and check > PCH_NONE as well. - It is not necessarily a chronological order, but a matter of south display compatibility/inheritance. v2: Rebased on top of Jani's clean-up which removed the need for less-than comparison Cc: Jani Nikula Cc: Ville Syrjälä Cc: Lucas De Marchi Signed-off-by: Rodrigo Vivi Reviewed-by: Lucas De Marchi Link: https://patchwork.freedesktop.org/patch/msgid/20190308214300.25057-3-rodrigo.vivi@intel.com --- drivers/gpu/drm/i915/i915_drv.h | 6 ++++++ drivers/gpu/drm/i915/i915_irq.c | 7 ++----- drivers/gpu/drm/i915/intel_cdclk.c | 2 +- drivers/gpu/drm/i915/intel_dp.c | 3 +-- drivers/gpu/drm/i915/intel_panel.c | 5 ++--- 5 files changed, 12 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 9ca048d52b0f..0ed6e871f609 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -523,6 +523,12 @@ struct i915_psr { u16 su_x_granularity; }; +/* + * Sorted by south display engine compatibility. + * If the new PCH comes with a south display engine that is not + * inherited from the latest item, please do not add it to the + * end.
