| * proc: Supply a function to remove a proc entry by PDEDavid Howells2013-05-011-1/+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.

* | | misc: generic on-chip SRAM allocation driverPhilipp Zabel2013-04-303-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

For drivers to be able to safely call the enable and disable hooks, the mei_cl_ops must be set before it's probed and thus this should happen before registering the device on the MEI bus.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define a truly synchronous API for the bus Tx path by putting all pending request to the write list and wait for the interrupt tx handler to wake us up. The ___mei_cl_send() out path is also slightly reworked to make it look more like main.c:mei_write().
