The tps65910_irq_exit() cleanup function was generating a warning from sparse due to the lack of a prototype. This wasn't causing GCC warnings as the driver wasn't cleaning up its IRQs on exit at all so there was no use of an unprototyped function. Signed-off-by:

This patch replaces the code for getting an unsigned long from a userspace buffer by a simple call to kstroul_from_user. This makes it easier to read and less error prone. Signed-off-by:

When the byte swap was factored out into the per-register I/O functions the register restore for the IRQ mask cache (which we use and store in CPU native format for the interrupt handler) was not updated to do a byte swap when it uses the bulk I/O. Fix this by writing the cache out one register at a time. Signed-off-by:

The WM831x AUXADC hardware can schedule multiple conversions at once, allowing higher performance when more than one source is in use as we can have the hardware start new conversions without having to wait for a register write. Take advantage of this in the interrupt driven case, maintaining a list of callers that are waiting for AUXADC conversions and completing them all simultaneously. The external interface of the AUXADC is not changed so there will be limited use of the feature immediately. Signed-off-by:

This allows boards to leave the irq_base field unitialized and prevents them having to reserve irqs in the platform. pdata can be optional for irq support now. Without pdata the driver allocates some free irq range. With pdata and irq_base > 0 the driver allocates exactly the specified irq. Without pdata the irq defaults to IRQF_TRIGGER_LOW. Signed-off-by:

In preparation for some additional work on the wm831x AUXADC code move the support into a separate file. This is a simple code motion patch, there should be no functional changes. Signed-off-by:

Mark Brown authored
Ensure that there's no possibility of loosing an AUXADC interrupt by reading the conversion result in the IRQ handler when using interrupts. Otherwise it's possible that under very heavy load a new conversion could be initiated before the acknowledgement for a previous interrupt has happened. Signed-off-by:

Use irq_allocate_desc() to get the IRQ range, which turns into a noop on non-sparse systems. Since all existing users are non-sparse there should be no compatibility issues. Signed-off-by:

The WM831x IRQ set_type() operation is doing a direct register write when called but since set_type() is called with the bus lock held this isn't legal and could cause deadlocks in the IRQ core. Fix this by posting the updates into an array and syncing in the bus_sync_unlock() callback. Signed-off-by:

Note: When upper layer's read/write request cannot be fulfilled, the block layout driver shouldn't silently mark the page as error. It should do what can be done and leave the rest to the upper layer. To do so, we should set rdata/wdata->res.count properly. When upper layer re-send the read/write request to finish the rest part of the request, pgbase is the position where we should start at.

In blocklayout driver. There are two things happening while layoutcommit/cleanup. 1. the modified extents are encoded. 2. On cleanup the extents are put back on the layout rw extents list, for reads. In the new system where actual xdr encoding is done in encode_layoutcommit() directly into xdr buffer, these are the new commit stages: 1. On setup_layoutcommit, the range is adjusted as before and a structure is allocated for communication with bl_encode_layoutcommit && bl_cleanup_layoutcommit (Generic layer provides a void-star to hang it on) 2. bl_encode_layoutcommit is called to do the actual encoding directly into xdr. The commit-extent-list is not freed and is stored on above structure. FIXME: The code is not yet converted to the new XDR cleanup 3. On cleanup the commit-extent-list is put back by a call to set_to_rw() as before, but with no need for XDR decoding of the list as before. And the commit-extent-list is freed. Finally allocated structure is freed. [rm inode and pnfs_layout_hdr args from cleanup_layoutcommit()] Signed-off-by:
