2010-07-27ARM: 6158/2: PL011 baudrate extension for ST-Ericssons derivativeLinus Walleij1-2/+25
Implementation of the ST-Ericsson baudrate extension in the PL011 block. In this modified variant it is possible to change the sampling factor from 16 to 8, and thanks to this we can get higher baudrates while still using the same peripheral clock. Also replace the simple division to determine the baud divisor with DIV_ROUND_CLOSEST() rather than a simple integer division.

This results in a namespace clash with multiple definitions of several symbols when compiling both drivers in the kernel.

2010-07-11powerpc/cpm: Reintroduce global spi_pram struct (fixes build issue)Anton Vorontsov1-22/+0
spi_t was removed in commit 644b2a680ccc51a9ec4d6beb12e9d47d2dee98e2 ("powerpc/cpm: Remove SPI defines and spi structs"), the commit assumed that spi_t isn't used anywhere outside of the spi_mpc8xxx driver. But it appears that the struct is needed for micropatch code. So, let's reintroduce the struct. Fixes the following build issue: CC arch/powerpc/sysdev/micropatch.o micropatch.c: In function 'cpm_load_patch': micropatch.c:629: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token micropatch.c:629: error: 'spp' undeclared (first use in this function) micropatch.c:629: error: (Each undeclared identifier is reported only once micropatch.c:629: error: for each function it appears in.)

2010-07-09hwmon: (it87) Fix in7 on IT8720FJean Delvare1-0/+22
The IT8720F has no VIN7 pin, so VCCH should always be routed internally to VIN7 with an internal divider. Curiously, there still is a configuration bit to control this, which means it can be set incorrectly. And even more curiously, many boards out there are improperly configured, even though the IT8720F datasheet claims that the internal routing of VCCH to VIN7 is the default setting. So we force the internal routing in this case. It turns out that all boards with the wrong setting are from Gigabyte, so I suspect a BIOS bug. But it's easy enough to workaround in the driver, so let's do it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Jean-Marc Spaggiari <jean-marc@spaggiari.org> Cc: stable@kernel.org

2010-07-07drm: correctly update connector DPMS status in drm_fb_helperJesse Barnes1-3/+20
We don't currently update the DPMS status of the connector (both in the connector itself and the connector's DPMS property) in the fb helper code. This means that if the kernel FB core has blanked the screen, sysfs will still show a DPMS status of "on". It also means that when X starts, it will try to light up the connectors, but the drm_crtc_helper code will ignore the DPMS change since according to the connector, the DPMS status is already on.

2010-07-07drm/ttm: Allocate the page pool manager in the heap.Francisco Jerez1-35/+33
Repeated ttm_page_alloc_init/fini fails noisily because the pool manager kobj isn't zeroed out between uses (we could do just that but statically allocated kobjects are generally considered a bad thing). Move it to kzalloc'ed memory. Note that this patch drops the refcounting behavior of the pool allocator init/fini functions: it would have led to a race condition in its current form, and anyway it was never exploited. This fixes a regression with reloading kms modules at runtime, since page allocator was introduced.
