From b78eabde89f9b19d463a77abe420508c0ef29249 Mon Sep 17 00:00:00 2001
From: Andrew Victor <linux@maxim.org.za>
Date: Wed, 2 Apr 2008 21:38:40 +0100
Subject: [ARM] 4902/1: [AT91] SAM9/CAP9 memory controller header

The AT91CAP9 processor includes the same Static Memory Controller
(SMC) peripheral as the SAM9 processors, but replaces the SDRAM
Controller with a DDR/SDR Controller (DDRSDRC).

This patch splits the existing
include/asm-arm/arch-at91/at91sam926x_mc.h into at91sam9_sdramc.h and
at91sam9_smc.h.
It also adds an at91cap9_ddrsdr.h for the DDRSDRC controller.

Subject: [ARM] 4903/1: [AT91] SAM9/CAP9 system shutdown

Enable system shutdown/power-off on AT91SAM9 and AT91CAP9 based boards.
This does not require power-management to be enabled, and the
pm_power_off method can be overridden in board-specific files if
necessary.

Subject: [ARM] 4907/1: [AT91] SAM9/CAP9 reset reason

The Reset controller on the SAM9/CAP9 processors will store the reason
for the last system reset.
On startup, display this information (wakeup signal, RTT alarm,
watchdog reset, user reset, etc)

Based on patch from David Brownell.

Subject: [ARM] 4908/1: [AT91] RTT platform_device fix

The RTT-as-RTC driver will search for the user-specified RTT
peripheral via ID number (0 .. 1).
Therefore if the processor only contains a single RTT peripheral, we
need to set its platform_device.id to "0" instead of "-1".
Also add the missing platform_device resource for the CAP9 processor.

Bug reported by Sedji Gaouaou.

Subject: [ARM] 4982/1: [AT91] Drop old-style UART initialization (Part 1)

All the SAM9 boards supported by mainline and the AT91 patches have
been converted to the new-style UART initialization.  Therefore drop
support for the old at91_init_serial() interface for SAM9.

at91_uarts[] array can also be marked as __initdata.

The warning that no serial-console is defined moved from
at91_set_serial_console() to at91_add_device_serial() since the whole
point is the board-specific file is not calling
at91_set_serial_console().

From ad48ce74f70a201c4c1cf3b4e8f6b6203a2e4a8d Mon Sep 17 00:00:00 2001
From: Andrew Victor <linux@maxim.org.za>
Date: Wed, 16 Apr 2008 20:43:49 +0100
Subject: [ARM] 4989/1: [AT91] SAM9 ClockSource / ClockEvents

Update AT91SAM9/CAP9 PIT driver to use generic time and clockevent
infrastructure:

 - Clocksource gives sub-microsecond timestamp precision, assuming
 memory is clocked at over 16 MHz.  It's less than a 32 bit counter,
 unless it's is also generating IRQs.

 - Clockevent device supports periodic mode only; no oneshot
 support from this hardware.  No IRQs generated unless it's the
 active clocksource.

Later, another timer (probably from a TC module) can provide a oneshot
clockevent device to get NO_HZ and High-Res-Timer behavior.

This also updates the timekeeping to use the actual master clock rate
on the system, instead of compile-time <asm/arch/timex.h> constants
matching what Atmel's EK boards use.  (Product boards may well differ!)

Plus cleanup:  rename "*_timer*" symbols to "*_pit*" (there are other
timers, but only one PIT); shorter lines; remove needless CPP stuff;
make several symbols static; etc.
