2011-03-03omap: mailbox: resolve hang issueHari Kanigeri
omap4 interrupt disable bits is different. On rx kfifo full, the mbox rx interrupts wasn't getting disabled, and this is causing the rcm stress tests to hang.

2011-02-24OMAP: mailbox: build device using omap_device/omap_hwmodFelipe Contreras
Remove static platform_device and resource data within omap mailbox driver; use the one defined in the hwmod database along with omap_device framework for device build and registration. Add device latency functions to be used, so clock can be enabled and sysconfig is configured.

2011-02-14OMAP2420: mailbox: fix IVA vs DSP IRQ numberingKevin Hilman
The IRQ numbering for the IVA and DSP mailboxes was switched due to the wrong ordering in the OMAP2 mbox list. Switch the ordering so DSP is first and matches all the other SoCs. Tested on OMAP2420/n810. Signed-off-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-02-23omap: mailbox: correct OMAP4 reset logicSuman Anna
OMAP4 mailbox has a different register set. There is no MAILBOX_SYSSTATUS register. The reset is indicated with the SOFTRESET bit of the MAILBOX_SYSCONFIG register itself. This bit should read 0 for a successful Reset. Also, the SOFTRESET bit occupies bit0 and not bit1 as with previous generations.

2009-09-24omap: mailbox: Flush posted write when acking mailbox irqHiroshi DOYU
The only way to flush posted write to L4 bus is to do a read back of the same register right after the write. This seems to be mostly needed in interrupt handlers to avoid causing spurious interrupts. The earlier fix has been to mark the L4 bus as strongly ordered memory, which solves the problem, but causes performance penalties.
