From: Ander Conselvan de Oliveira Date: Wed, 22 Feb 2017 06:34:26 +0000 (+0200) Subject: drm/i915: Store aux power domain in intel_dp X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5432fcaff3cee045ddbd94f29802ee3ac4f50283;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Store aux power domain in intel_dp The aux power domain only makes sense in the DP code. Storing it in struct intel_dp avoids some indirection. v2: Rebase Signed-off-by: Ander Conselvan de Oliveira Reviewed-by: Imre Deak Link: http://patchwork.freedesktop.org/patch/msgid/20170222063431.10060-2-ander.conselvan.de.oliveira@intel.com --- diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 5a91f6741fed..e9fb2edb9dd7 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -5587,26 +5587,6 @@ static enum intel_display_power_domain port_to_power_domain(enum port port) } } -static enum intel_display_power_domain port_to_aux_power_domain(enum port port) -{ - switch (port) { - case PORT_A: - return POWER_DOMAIN_AUX_A; - case PORT_B: - return POWER_DOMAIN_AUX_B; - case PORT_C: - return POWER_DOMAIN_AUX_C; - case PORT_D: - return POWER_DOMAIN_AUX_D; - case PORT_E: - /* FIXME: Check VBT for actual wiring of PORT E */ - return POWER_DOMAIN_AUX_D; - default: - MISSING_CASE(port); - return POWER_DOMAIN_AUX_A; - } -} - enum intel_display_power_domain intel_display_port_power_domain(struct intel_encoder *intel_encoder) { @@ -5634,36 +5614,6 @@ intel_display_port_power_domain(struct intel_encoder *intel_encoder) } } -enum intel_display_power_domain -intel_display_port_aux_power_domain(struct intel_encoder *intel_encoder) -{ - struct drm_i915_private *dev_priv = to_i915(intel_encoder->base.dev); - struct intel_digital_port *intel_dig_port; - - switch (intel_encoder->type) { - case INTEL_OUTPUT_UNKNOWN: - case INTEL_OUTPUT_HDMI: - /* - * Only DDI platforms should ever use these output types. - * We can get here after the HDMI detect code has already set - * the type of the shared encoder.
