* mailbox/omap: remove omap_mbox_type_t from mailbox opsSuman Anna2014-07-29
| | | | | | | | | | | The type definition omap_mbox_type_t used for distinguishing OMAP1 from OMAP2+ mailboxes is no longer needed after the removal of OMAP1 mailbox driver, and has therefore been cleaned up. This cleanup also eliminates the need for the polling logic used for checking the transmit readiness. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* mailbox/omap: remove OMAP1 mailbox driverSuman Anna2014-07-29
| | | | | | | | | | | | | | | | There are no existing users for OMAP1 mailbox driver in kernel. Commit ab6f775 "Removing dead OMAP_DSP" has cleaned up all the dead code related to the only possible user, including the creation of the mailbox platform device. Remove this stale driver so that the OMAP mailbox driver can be simplified and streamlined better for converting to mailbox framework.

* mailbox/omap: use devm_* interfacesSuman Anna2014-07-29
| | | | | | | | Use the various devm_ interfaces to simplify the cleanup in probe and remove functions in OMAP2+ mailbox driver. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* drivers/mailbox/omap: make mbox->irq signed for error handlingDan Carpenter2014-01-23
| | | | | | | | | | | | | | | | | There is a bug in omap2_mbox_probe() where we try do: mbox->irq = platform_get_irq(pdev, info->irq_id); if (mbox->irq < 0) { The problem is that mbox->irq is unsigned so the error handling doesn't work. I've changed it to a signed integer.

* mailbox: remove unnecessary platform_set_drvdata()Jingoo Han2013-09-18
| | | | | | | | | | The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.

* mailbox/omap: move the OMAP mailbox framework to driversSuman Anna2013-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
