2014-11-27mailbox/omap: adapt to the new mailbox frameworkSuman Anna1-24/+27
The OMAP mailbox driver and its existing clients (remoteproc for OMAP4+) are adapted to use the generic mailbox framework. The main changes for the adaptation are: - The tasklet used for Tx is replaced with the state machine from the generic mailbox framework. The workqueue used for processing the received messages stays intact for minimizing the effects on the OMAP mailbox clients. - The existing exported client API, omap_mbox_get, omap_mbox_put and omap_mbox_send_msg are deleted, as the framework provides equivalent functionality. A OMAP-specific omap_mbox_request_channel is added though to support non-DT way of requesting mailboxes. - The OMAP mailbox driver is integrated with the mailbox framework through the proper implementations of mbox_chan_ops, except for .last_tx_done and .peek_data. The OMAP mailbox driver does not need these ops, as it is completely interrupt driven. - The OMAP mailbox driver uses a custom of_xlate controller ops that allows phandles for the pargs specifier instead of indexing to avoid any channel registration order dependencies. - The new framework does not support multiple clients operating on a single channel, so the reference counting logic is simplified. - The remoteproc driver (current client) is adapted to use the new API. The notifier callbacks used within this client is replaced with the regular callbacks from the newer framework. - The exported OMAP mailbox API are limited to omap_mbox_save_ctx, omap_mbox_restore_ctx, omap_mbox_enable_irq & omap_mbox_disable_irq, with the signature modified to take in the new mbox_chan handle instead of the OMAP specific omap_mbox handle. The first 2 will be removed when the OMAP mailbox driver is adapted to runtime_pm. The other exported API omap_mbox_request_channel will be removed once existing legacy users are converted to DT.

2014-06-17remoteproc: da8xx: don't select CMA on no-MMUArnd Bergmann1-1/+1
We can only use CMA on systems that have an MMU, because of the requirement to use memory migration. NOMMU systems are rather constrained to start with, but it seems reasonable to assume that DMA allocations can still succeed in the constrained case for remoteproc on NOMMU, so this patch changes the da8xx implementation to not rely on CMA when the MMU is disabled.

2013-10-29virtio_ring: change host notification APIHeinz Graalfs1-1/+2
Currently a host kick error is silently ignored and not reflected in the virtqueue of a particular virtio device. Changing the notify API for guest->host notification seems to be one prerequisite in order to be able to handle such errors in the context where the kick is triggered. This patch changes the notify API. The notify function must return a bool return value. It returns false if the host notification failed.

2013-07-01remoteproc: free carveout memories only after unmapping themSuman Anna1-7/+7
It is not preferable to have the allocated pages for carveout memories freed before they are unmapped. The code that deals with the cleanup of carveout memories is therefore moved after the corresponding mapping entries were cleaned up. This is mostly a no-op since the remote processors are already stopped when the cleanup function is called, but this will make the cleanup code follow the exact reverse path of allocation.

2013-06-11mailbox/omap: move the OMAP mailbox framework to driversSuman Anna2-2/+3
The mailbox hardware (in OMAP) uses a queued mailbox interrupt mechanism that provides a communication channel between processors through a set of registers and their associated interrupt signals by sending and receiving messages. The OMAP mailbox framework/driver code is moved to be under drivers/mailbox, in preparation for adapting to a common mailbox driver framework. This allows the build for OMAP mailbox to be enabled (it was disabled during the multi-platform support). As part of the migration from plat and mach code: - Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers. - mailbox.h under plat-omap/plat/include has been split into a public and private header files. The public header has only the API related functions and types. - The module name mailbox.ko from plat-omap is changed to omap-mailbox.ko - The module name mailbox_mach.ko from mach-omapX is changed as mailbox_omap1.ko for OMAP1 mailbox_omap2.ko for OMAP2+ Cc: Tony Lindgren <tony@atomide.com> [gregkh@linuxfoundation.org: ack for staging part] Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com> Signed-off-by: Suman Anna <s-anna@ti.com>

2013-02-15remoteproc: omap: depend on OMAP_MBOX_FWKArnd Bergmann1-1/+1
Patch a62a6e98 "ARM: OMAP2+: Disable code that currently does not work with multiplaform" makes the OMAP_MBOX_FWK option depend on !MULTIPLATFORM, which means we cannot simply select that symbol from OMAP_REMOTEPROC. Turning the 'select' into 'depends on' ensures that all dependencies are correct until OMAP_MBOX_FWK loses its dependency. Without this patch, building allmodconfig results in: drivers/remoteproc/omap_remoteproc.c:31:26: fatal error: plat/mailbox.h: No such file or directory Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Tony Lindgren <tony@atomide.com> Acked-by: Ohad Ben-Cohen <ohad@wizery.com>

2013-01-21drivers/remoteproc: remove depends on CONFIG_EXPERIMENTALKees Cook1-4/+1
The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

2013-01-03Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
