From aa1d6068a460dcb21e69f6d65fa7d3ab483d547a Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Mon, 10 Jan 2022 21:15:57 -0800 Subject: [PATCH] drm/i915: Move SNPS PHY registers to their own header These registers are only needed in a couple files and on specific platforms; let's keep them separate from the general register pool. v2: - Don't forget to include i915_reg_defs.h (Jani) - Ensure include guard matches header name (Jani) Cc: Jani Nikula Signed-off-by: Matt Roper Reviewed-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20220111051600.3429104-9-matthew.d.roper@intel.com --- drivers/gpu/drm/i915/display/intel_snps_phy.c | 1 + drivers/gpu/drm/i915/display/intel_snps_phy_regs.h | 75 ++++++++++++++++++++++ drivers/gpu/drm/i915/i915_reg.h | 67 ------------------- 3 files changed, 76 insertions(+), 67 deletions(-) create mode 100644 drivers/gpu/drm/i915/display/intel_snps_phy_regs.h diff --git a/drivers/gpu/drm/i915/display/intel_snps_phy.c b/drivers/gpu/drm/i915/display/intel_snps_phy.c index 09f405e..718bfdb 100644 --- a/drivers/gpu/drm/i915/display/intel_snps_phy.c +++ b/drivers/gpu/drm/i915/display/intel_snps_phy.c @@ -10,6 +10,7 @@ #include "intel_de.h" #include "intel_display_types.h" #include "intel_snps_phy.h" +#include "intel_snps_phy_regs.h" /** * DOC: Synopsis PHY support diff --git a/drivers/gpu/drm/i915/display/intel_snps_phy_regs.h b/drivers/gpu/drm/i915/display/intel_snps_phy_regs.h new file mode 100644 index 0000000..0543465 --- /dev/null +++ b/drivers/gpu/drm/i915/display/intel_snps_phy_regs.h @@ -0,0 +1,75 @@ +/* SPDX-License-Identifier: MIT */ +/* + * Copyright © 2022 Intel Corporation + */ + +#ifndef __INTEL_SNPS_PHY_REGS__ +#define __INTEL_SNPS_PHY_REGS__ + +#include "i915_reg_defs.h" + +#define _SNPS_PHY_A_BASE 0x168000 +#define _SNPS_PHY_B_BASE 0x169000 +#define _SNPS_PHY(phy) _PHY(phy, \ + _SNPS_PHY_A_BASE, \ + _SNPS_PHY_B_BASE) +#define _SNPS2(phy, reg) (_SNPS_PHY(phy) -
