linux-toradex.git/drivers, branch v3.10.14 Linux kernel for Apalis and Colibri modules Properly handle tristate dependencies on USB/PCI menus 2013-10-01T16:17:48+00:00 Mauro Carvalho Chehab mchehab@redhat.com 2013-05-22T14:25:52+00:00 7b7b9915f77d3c5db399866080751e9dafc9136f commit 5077ac3b8108007f4a2b4589f2d373cf55453206 upstream. As USB/PCI/MEDIA_SUPPORT dependencies can be tristate, we can't simply make the bool menu to be dependent on it. Everything below the menu should also depend on it, otherwise, we risk to allow building them with 'y', while only 'm' would be supported. So, add an IF just before everything below, in order to avoid such risks.

simply make the bool menu to be dependent on it. Everything below
the menu should also depend on it, otherwise, we risk to allow
building them with 'y', while only 'm' would be supported.

So, add an IF just before everything below, in order to avoid
such risks.

commit a0f9354b1a319cb29c331bfd2e5a15d7f9b87fa4 upstream.

(a.k.a. Kconfig bool depending on a tristate considered harmful)
Fix various build errors when CONFIG_USB=m and media USB drivers
are builtin.  In this case, CONFIG_USB_ZR364XX=y,
CONFIG_VIDEO_PVRUSB2=y, and CONFIG_VIDEO_STK1160=y.
This is caused by (from drivers/media/usb/Kconfig):
menuconfig MEDIA_USB_SUPPORT
	bool "Media USB Adapters"
	depends on USB && MEDIA_SUPPORT
	           =m     =y
so MEDIA_USB_SUPPORT=y and all following Kconfig 'source' lines
are included.  By adding an "if USB" guard around most of this file,
the needed dependencies are enforced.

The OUTPUT_ENABLE action jumps past the point in the coder where the data_offset is set on certain rs780 cards. This worked previously because the OUTPUT_ENABLE action is always called immediately after the ENABLE action so the data_offset remained set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57 (drm/radeon/atom: initialize more atom interpretor elements to 0), we explictly reset data_offset to 0 between atom calls which then caused this to fail. The fix is to just skip calling the OUTPUT_ENABLE action on the problematic chipsets. The ENABLE action does the same thing and more.

drm/radeon: fix handling of variable sized arrays for router objects 2013-10-01T16:17:47+00:00 Alex Deucher alexander.deucher@amd.com 2013-08-27T16:36:01+00:00 911181cc6e98ee814b4f1616d1b59a54b6bb8e6f commit fb93df1c2d8b3b1fb16d6ee9e32554e0c038815d upstream. The table has the following format: typedef struct _ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT //usSrcDstTableOffset pointing to this structure { UCHAR ucNumberOfSrc; USHORT usSrcObjectID[1]; UCHAR ucNumberOfDst; USHORT usDstObjectID[1]; }ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT; usSrcObjectID[] and usDstObjectID[] are variably sized, so we can't access them directly. Use pointers and update the offset appropriately when accessing the Dst members.

commit fb93df1c2d8b3b1fb16d6ee9e32554e0c038815d upstream.

The table has the following format:

typedef struct _ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT         //usSrcDstTableOffset pointing to this structure
{
  UCHAR               ucNumberOfSrc;
  USHORT              usSrcObjectID[1];
  UCHAR               ucNumberOfDst;
  USHORT              usDstObjectID[1];
}ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT;

usSrcObjectID[] and usDstObjectID[] are variably sized, so we
can't access them directly.  Use pointers and update the offset
appropriately when accessing the Dst members.

drm/radeon: fix resume on some rs4xx boards (v2) 2013-10-01T16:17:47+00:00 Alex Deucher alexander.deucher@amd.com 2013-08-26T21:52:12+00:00 a7b153243b75dc0633a0ef85f1598d719a6624e6 commit acf88deb8ddbb73acd1c3fa32fde51af9153227f upstream. Setting MC_MISC_CNTL.GART_INDEX_REG_EN causes hangs on some boards on resume. The systems seem to work fine without touching this bit so leave it as is. v2: read-modify-write the GART_INDEX_REG_EN bit. I suspect the problem is that we are losing the other settings in the register. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=52952 Reported-by: Ondrej Zary <linux@rainbow-software.org> Tested-by: Daniel Tobias <dan.g.tob@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

some boards on resume.  The systems seem to work fine
without touching this bit so leave it as is.

v2: read-modify-write the GART_INDEX_REG_EN bit.
I suspect the problem is that we are losing the other
settings in the register.
