6b23398591 omap mailbox: Set a device in logical mbox instance for traceability
With this patch, you'll get the following sysfs directories. This
structure implies that a single platform device, "omap2-mailbox" holds
multiple logical mbox instances. This could be the base to add sysfs
files for each logical mboxes. Then userland application can access a
mbox through sysfs entries if necessary(ex: setting kfifo size
dynamically)

b5bebe4102 omap: mailbox: convert block api to kfifo
The underlying buffering implementation of mailbox
is converted from block API to kfifo due to the simplicity
and speed of kfifo.

The default size of the kfifo buffer is set to 256 bytes.
This value is configurable at compile time (via
CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at
runtime (via the mbox_kfifo_size module parameter).

the workqueue which get elements from the request queue is never

58dcfb3a0f omap: 3630: disable TLL SAR on 3630 ES1
USBTLL Save-and-Restore is broken in 3630 ES1.0. Having it
enabled could result in incorrect register restores as
the OMAP exits off-mode. This could potentially result in
unexpected wakeup events.

(Refer 3630 errata ID i579)

This is fixed in ES1.1. So disable it for ES1.0s.

Additionally, update some of the CHIP_GE_* macros to use other
