From dcfc3552136fb6996e19b9f6980dc5a6721defd5 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Tue, 29 Jul 2014 18:06:16 +0100 Subject: [PATCH] drm/i915: Specify when the PLL hw state fields are valid Not all those fields are valid on a given platform. Make it explicit. Unions could also be used, but were cluttering some code paths with if/else ladders. v2: Don't use anonymous unions (Daniel) Signed-off-by: Damien Lespiau Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_drv.h | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index c70b2b67282e..c3beb08813c6 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -197,10 +197,13 @@ enum intel_dpll_id { #define I915_NUM_PLLS 2 struct intel_dpll_hw_state { + /* i9xx, pch plls */ uint32_t dpll; uint32_t dpll_md; uint32_t fp0; uint32_t fp1; + + /* hsw, bdw */ uint32_t wrpll; }; -- 2.20.1
