From 9583c099b4a08b49e03f7b461c344b6d277fd262 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Wed, 10 Dec 2008 15:47:28 -0800 Subject: Revert "Merge branch 'modesetting-gem'" This reverts commit 6656db10551bbb8770dd945b6d81d5138521f208. We really just want the libdrm and ioctl bits, not all the driver stuff. --- linux-core/dvo_sil164.c | 302 ------------------------------------------------ 1 file changed, 302 deletions(-) delete mode 100644 linux-core/dvo_sil164.c (limited to 'linux-core/dvo_sil164.c') diff --git a/linux-core/dvo_sil164.c b/linux-core/dvo_sil164.c deleted file mode 100644 index 033a4bb0..00000000 --- a/linux-core/dvo_sil164.c +++ /dev/null @@ -1,302 +0,0 @@ -/************************************************************************** - -Copyright © 2006 Dave Airlie - -All Rights Reserved. - -Permission is hereby granted, free of charge, to any person obtaining a -copy of this software and associated documentation files (the -"Software"), to deal in the Software without restriction, including -without limitation the rights to use, copy, modify, merge, publish, -distribute, sub license, and/or sell copies of the Software, and to -permit persons to whom the Software is furnished to do so, subject to -the following conditions: - -The above copyright notice and this permission notice (including the -next paragraph) shall be included in all copies or substantial portions -of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS -OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF -MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. -IN NO EVENT SHALL THE AUTHOR BE LIABLE FOR -ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, -TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE -SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. - -**************************************************************************/ - -#include "dvo.h" - -#define SIL164_VID 0x0001 -#define SIL164_DID 0x0006 - -#define SIL164_VID_LO 0x00 -#define SIL164_VID_HI 0x01 -#define SIL164_DID_LO 0x02 -#define SIL164_DID_HI 0x03 -#define SIL164_REV 0x04 -#define SIL164_RSVD 0x05 -#define SIL164_FREQ_LO 0x06 -#define SIL164_FREQ_HI 0x07 - -#define SIL164_REG8 0x08 -#define SIL164_8_VEN (1<<5) -#define SIL164_8_HEN (1<<4) -#define SIL164_8_DSEL (1<<3) -#define SIL164_8_BSEL (1<<2) -#define SIL164_8_EDGE (1<<1) -#define SIL164_8_PD (1<<0) - -#define SIL164_REG9 0x09 -#define SIL164_9_VLOW (1<<7) -#define SIL164_9_MSEL_MASK (0x7<<4) -#define SIL164_9_TSEL (1<<3) -#define SIL164_9_RSEN (1<<2) -#define SIL164_9_HTPLG (1<<1) -#define SIL164_9_MDI (1<<0) - -#define SIL164_REGC 0x0c - -struct sil164_save_rec { - uint8_t reg8;
