Cover letter [PATCH 0/7] OMAP mailbox cleanup
Quoted 48 lines · Tony Lindgren
Quoted 35 lines · Suman Anna

Hi,

This patch series is mainly a cleanup of the current OMAP mailbox drivers in preparation for adding DT support and adoption to the upcoming mailbox framework from Jassi Brar [1]. It removes the OMAP1 mailbox driver as there are no users for it in the kernel, and consolidates the previous OMAP mailbox framework and the OMAP2+ mailbox driver into a single OMAP mailbox driver.

The last patch also allows the OMAP mailbox driver to support multiple instances of the IP (for DRA7xx, which is the first SoC in the OMAP family to have more than one System Mailbox IP).

The patches are based on 3.16-rc2 and do not change any of the functional behavior on any OMAP2+ SoCs. The boot logs on various OMAP platforms with these patches are at:

I'll apply these on into omap-for-v3.17/mailbox. Might be a bit too late for v3.17 so no guarantees these will get merged.

Understood. Thanks Tony. I will repost them once rc1 is out _if_ they don't make it.

Suman

But it removes some old dead code, so that's nice ;)

Regards,

Tony
