Subject: [ARM] 3578/1: AT91RM9200 Clock update

Patch from Andrew Victor

Some updates to the clock infrastructure for the AT91RM9200.

1. Hard-coded values replaced with names defined in at91rm9200_sys.h.
2. Added the four PIO clocks, which are enabled at startup.
3. At startup, disable all unused clocks.
4. Minor bugfix for usage counts associated with MCK. [Patch from David
Brownell]
5. Added at91_clock_associate() function to associate device & function
with a particular clock.  [Patch from David Brownell]

Subject: [ARM] 3579/1: AT91RM9200 Timer simplification

Patch from Andrew Victor

Use a global variable 'last_crtr' to store the time of the last timer
tick instead of the ST_RTAR register.
It's faster, frees up the ST_RTAR register for other uses, and hopefully
makes the code more understandable.  [Patch from Peter Menzebach]

Also add the SA_TIMER flag to Timer IRQ.  (It seems to be required for
the realtime preempt patch).

Subject: [ARM] 3585/1: AT91RM9200 Platform devices

Patch from Andrew Victor

This patch updates the platform device support for the AT91RM9200.

The changes include:

1. USB Host device renamed to "at91_ohci" since the driver is also
usable on the AT91SAM9261 processor.
2. Enabling multidrive on the USB Device's pullup pin should not be done
for all boards.  Moved into board-specific files.  [Patch from David
Brownell]
3. Move enabling of PCMCIA/Compact Flash pins out of the driver.
4. Added SPI device and resources.
5. Added Watchdog device and resources.  [Patch from David Brownell]
6. Added UART device and resources.
7. The simple devices (watchdog, rtc, i2c) are now automatically
registered and don't have to be registered separately in each
board-specific file. [Patch from David Brownell]

Subject: [ARM] 3588/1: AT91RM9200 CSB337/637 board update

Patch from Andrew Victor

This patch updates the support for the Cogent CSB337 and CSB637 boards.

The changes include:
1. Use the new at91_uart_config structure and device registration
functions for the UARTs.
2. Registration of I2C and SPI platform devices.
3. The CSB337 board uses PB0 & PB1 (and not PB2) for the LEDs.  [Patch
from David Brownell]

Subject: [ARM] 3589/1: AT91RM9200 DK/EK board update

Patch from Andrew Victor

This patch updates the support for the Atmel DK and EK boards.

The changes include:
1. Use the new at91_uart_config structure and device registration
functions for the UARTs.
2. Registration of I2C and SPI platform devices.
3. The USB Device pullup line is connected to reset, so multidrive needs
to be enabled on the line.  [Patch from David Brownell].

Subject: [ARM] 3604/1: AT91RM9200 New boards

Patch from Andrew Victor

This patch adds support for an additional 4 AT91RM9200-based boards:

1. Conitec ARM&EVA  [MACH_CARMEVA]
   (http://www.conitec.net/english/linuxboard.htm)

2. KwikByte KB920x  [MACH_KB9200]
   (http://kwikbyte.com/KB9202_description_new.htm)

3. Embest ATEB9200  [MACH_ATEB9200]
   (http://www.embedinfo.com/english/product/ATEB9200.asp)

4. Sperry-Sun KAFA board  [MACH_KAFA]
   (unknown)

From 907d6deb625cd7ff5fea3ef4b20dfb6c1c19c3ee Mon Sep 17 00:00:00 2001
From: Andrew Victor <andrew@sanpeople.com>
Date: Tue, 20 Jun 2006 19:30:19 +0100
Subject: [ARM] 3605/1: AT91RM9200 Power Management

Patch from Andrew Victor

This patch adds the core Power Management support for the AT91RM9200
processor.  It will support suspend-to-RAM and standby modes.

The suspend-to-RAM functionality is not 100% complete.  The code that
needs to be execute from the internal SRAM to restore the system is
outstanding.  For now we just fall through to Standby mode.

The AT91-specific at91_suspend_entering_slow_clock() function will
eventually be replaced by clk_must_disable() once that functionality is
added to mainline clock API.

Patch from David Brownell.

Subject: [ARM] 3607/1: AT91RM9200 misc fixes

Patch from Andrew Victor

This final patch includes some general fixes.

1. Link in pm.o if CONFIG_PM is enabled.  [Should have been included in
patch 3605/1].
2. Use __raw_readl()/__raw_writel() when accessing System Peripheral
registers.
3. Removed some unnecessary includes

Subject: [ARM] 3675/2: Preparing for AT91SAM926 support

Patch from Andrew Victor

This prepares the way for adding support for the new Atmel AT91SAM926x
processors.

Major changes:
- Rename time.c to at91rm9200_time.c
- Rename common.c to at91rm9200.c
- Introduce ARCH_AT91, of which ARCH_AT91RM9200, ARCH_AT91SAM9260 and
ARCH_AT91SAM9261 are dependent.

Subject: [PATCH] ARM: fixup irqflags breakage after ARM genirq merge

The irgflags consolidation did conflict with the ARM to generic IRQ
conversion and was not applied for ARM. Fix it up.

Use the new IRQF_ constants and remove the SA_INTERRUPT define
