* cirrusfb: Laguna chipset 8bpp fixKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | Fix 8bpp mode by adding handling of the Laguna chipsets to various places and stop trashing a HDR register which probably does not exist on the Laguna. Fix compilation warnings about uninitialized variables also. Finally, all 8bpp, 16bpp and 32bpp modes work on the Laguna chipset.

* cirrusfb: various improvementsKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various improvements to the code: - kill a structure with only one field: multiplexing and use the field directly - move the cirrusfb_ops structure down the file to kill forward declarations - move cirrusfb_init() to kill forward declaration - kill register loads done already in the init_vgachip() - kill assigments done by higher layer in the cirrusfb_pan_display() - do not overwrite line pitch bit in the CL_CRT1D register - kill btype variables if they were used only once or twice - add cpu_relax() in the busy waiting loop The fix to the CL_CRT1D register handling makess the 1024x768 32bpp mode work. Previously, only lower resolution modes have worked with 32bpp. Signed-off-by: Krzysztof Helt <krzysztof.h1@poczta.fm> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* cirrusfb: use 5-6-5 RGB for 16bpp modeKrzysztof Helt2009-04-01
| | | | | | | | | | | | Use the 5-6-5 RGB mode instead of the 5-5-5 mode at 16bpp depth. It fixes colors in the 16bpp modes on Cirrus Laguna chips.

* cirrusfb: do not calculate line length twiceKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | A line length is calculated twice: first in the cirrusfb_decode_var() then in the cirrusfb_set_par_foo(). Use the first calculated value. A nice side effect is that 32bpp mode works now.

* cirrusfb: add mmio registers for Laguna chipsetsKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | | | The Laguna chipsets use special registers which are available through the mmio area. The cirrusfb driver does not use memory mapped registers for the PCI cards. Add the memory mapped area for Laguna chipsets and add basic usage of the special Laguna registers after SVGALIB code. This gives readable console at 16bpp on the GD-5465 (Laguna AGP). The 8bpp and 32bpp depths are still broken.

* autofs4: fix lookup deadlockIan Kent2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A deadlock can occur when user space uses a signal (autofs version 4 uses SIGCHLD for this) to effect expire completion. The order of events is: Expire process completes, but before being able to send SIGCHLD to it's parent ... Another process walks onto a different mount point and drops the directory inode semaphore prior to sending the request to the daemon as it must ... A third process does an lstat on on the expired mount point causing it to wait on expire completion (unfortunately) holding the directory semaphore. The mount request then arrives at the daemon which does an lstat and, deadlock. For some time I was concerned about releasing the directory semaphore around the expire wait in autofs4_lookup as well as for the mount call back. I finally realized that the last round of changes in this function made the expiring dentry and the lookup dentry separate and distinct so the check and possible wait can be done anywhere prior to the mount call back. This patch moves the check to just before the mount call back and inside the directory inode mutex release.

| | | | | | | | | | | | | This solves the dependency between lis3lv02d.[ch] and ACPI specific methods. It introduces a ->bus_priv pointer to the device struct which is casted to 'struct acpi_device' in the ACIP layer. Changed hp_accel.c accordingly.

* hp_accel: axis conversion for hp compaq 8710wLuca Cappa2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I have a laptop HP Compaq 8710W, I compiled into my kernel the LIS3LV02DL and HP_ACCEL module drivers. While loading it cannot recognize the laptop model, so i am sending the necessary information to update the database of axis orientations. >When the laptop is horizontal the position reported is about 0 for X and Y >and a positive value for Z Yes, it is about 0,0,1000, the actual reading says: (-17,-26,1018); > If the left side is elevated, X increases (becomes positive) Yes, X goes toward to positive 1000. >If the front side (where the touchpad is) is elevated, Y decreases (becomes negative) No, Y goes toward to positive 1000. >If the laptop is put upside-down, Z becomes negative Yes, the laptop on a table Z gives 1000, and if upsidedown the Z reads -1000. So in few words the Y axis is inverted.

* hwmon: Add LTC4215 driverIra Snyder2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | Add Linux support for the Linear Technology LTC4215 Hot Swap controller I2C monitoring interface. I have tested the driver with my board, and it appears to work fine. With the power supplies disabled, it reads 11.93V input, 1.93V output, no current and no power. With the supplies enabled, it reads 11.93V input, 11.98V output, no current, no power. I'm not drawing any current at the moment, so this is reasonable. The value in the sense register never reads anything except 0, so I expect to get zero from the current and power calculations. I didn't attempt to support changing any of the chip's settings or enabling the FET. I'm not sure even how to do that and still fit within the hwmon framework. :) Signed-off-by: Ira W.
