2013-05-01proc: Supply a function to remove a proc entry by PDEDavid Howells1-1/+1
Supply a function (proc_remove()) to remove a proc entry (and any subtree rooted there) by proc_dir_entry pointer rather than by name and (optionally) root dir entry pointer. This allows us to eliminate all remaining pde->name accesses outside of procfs.

2013-04-29misc: generic on-chip SRAM allocation driverPhilipp Zabel3-0/+131
This driver requests and remaps a memory region as configured in the device tree. It serves memory from this region via the genalloc API. It optionally enables the SRAM clock. Other drivers can retrieve the genalloc pool from a phandle pointing to this drivers' device node in the device tree. The allocation granularity is hard-coded to 32 bytes for now, to make the SRAM driver useful for the 6502 remoteproc driver. There is overhead for bigger SRAMs, where only a much coarser allocation granularity is needed: At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap to track allocations.

2013-04-23misc: mark spear13xx-pcie-gadget as brokenArnd Bergmann1-1/+1
This driver was merged in 2.6.38 but never actually compiled because it depends on the <mach/pcie.h> header that has not made it into the kernel. Starting with Linux-3.10, this results in "allyesconfig" build errors, since spear13xx can now be enabled with the default "multiplatform" platform on ARM. Let's mark it as broken for now. If it doesn't get fixed, we can drop it completely.

2013-04-11misc: apds9802als: Fix suspend/resumeLars-Peter Clausen1-21/+4
The apds9802als driver implements runtime pm and at the same time uses the legacy pm callbacks for suspend and resume. This does not work since the i2c core wont look at the legacy pm callbacks if a driver has the 'pm' field set. This patch fixes it by moving over to dev_pm_ops for suspend/resume as well. Since both runtime pm and suspend/resume behave the same way this can easily be done using the UNIVERSAL_DEV_PM_OPS macro.

It should be left to the drivers to enable and disable the device on the MEI bus when e.g getting probed.

2013-04-01cs5535-mfgpt: Add another reset methodRichard Weinberger1-4/+37
The CS5535/CS5536 MFGPT has no support to reset the device. The current method uses an undocumented bit but does not work on all devices. At least on my ALIX board it completely freezes the board. This new method tries to soft reset all timers by unconfiguring them. But this does not clear the RO setup register and therefore it has to be ignored while probing. Resetting the timers is not only needed on broken BIOSes also when kexec is used. Otherwise the new kernel will find preconfigured timers and odd things will happen.
