From 2e908aeebd6804296e7d14a96de6be1e2de38e93 Mon Sep 17 00:00:00 2001
From: Matthias Brugger <matthias.bgg@gmail.com>
Date: Wed, 23 Jan 2013 19:50:38 +0100
Subject: [PATCH 2/2] omap2: twl-common: Add default power configuration
This patch adds a generic power script configuration.
When rebooting an OMAP3530 at 125 MHz, the reboot hangs.
With the generic power script, TWL4030 will be reset
when a warm reset occures. This way the OMAP3530 does not
hang on reboot.

Subject: [PATCH 2/6] mt9m032: Fix PLL setup
The MT9M032 PLL was assumed to be identical to the MT9P031 PLL but
differs significantly. Update the registers definitions and PLL limits
according to the datasheet.

Enable the regulators when powering the sensor up, and disable them when
powering it down.
The regulators are mandatory. Boards that don't allow controlling the
sensor power lines must provide fixed voltage regulators.

Actually it seems to be without PM. Thanks to analysis from Lokesh, the issue
can be seen even with just suspend or cpu hotplug. So cold boot as such is
fine.

This has been always the case it seems with CPU power cycle.
After the CPU is power cycled, 'DBGAUTHSTATUS' reads '0xaa' rather
than '0xaf' which means 'DBGEN = 0' and hence code fails to enable
monitor mode. This happens on both secure and GP devices and it can not
be patched since the secure code is ROM'ed. We didn't notice so far
because hw_breakpoint support was not default enabled on OMAP till the
multi-platform build.

Agree here too. As evident above, the feature won't work on OMAP4
devices with PM and hence some solution is needed.
What you think of below ?

Subject: [PATCH] ARM: hw_breakpoints: Check for CPU debug availability before
enabling it
CPU debug features like hardware break, watchpoints can be used only when
the debug mode is enabled and available for non-secure mode.
Hence check 'DBGAUTHSTATUS.DBGEN' before proceeding to enable the
features.
Thanks to Will for pointers and Lokesh for the analysis of the issue on
OMAP4 where after a CPU power cycle, debug mode gets disabled.

Subject: [PATCH 7/7] panda: spidev: setup pinmux
It works fine on my board, I've been able to perform data transfers using the spidev_test program provided in kernel documentation
(shortcut between SIMO and SOMI to perform an hardware loopback). I also checked that CS0 and CS1 and CLK are properly driven using my scope.
The clock is strangely configured as input, but it is also the case for omap3 beagle board, so I guess this is fine.
