cam60_spi_{flash_platform_data,partitions}
From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
To: linux-arm-kernel@lists.infradead.org
Subject: [PATCH 12/19] ARM: cam60: don't use __init for cam60_spi_{flash_platform_data,partitions}
Date: Thu, 5 Aug 2010 16:08:46 +0200
Message-Id: <1281017333-5563-12-git-send-email-u.kleine-koenig@pengutronix.de>
These two structs are referenced by cam60_spi_devices. The latter is
copied at init time to kmalloced memory and so the copy isn't freed after
booting. So it must not contain references to .init memory.
This isn't noticed by modpost as cam60_spi_devices is in .init.data, too.

cam60_spi_devices is passed to at91_add_device_spi which calls
spi_register_board_info. The latter makes a copy of it, so living in
.init.data is OK.
This fixes the following warning in cam60_defconfig:
WARNING: vmlinux.o(.data+0x2a00): Section mismatch in reference from the variable cam60_spi_devices to the (unknown reference) .init.data:(unknown)
The variable cam60_spi_devices references
the (unknown reference) __initdata (unknown)
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

Allow the vbus signal to optionally use polling. This is required if
the vbus signal is connected to an non-interrupting io expander for
example. If vbus is in polling mode, then it is assumed that the vbus
gpio may sleep. Also add an option to have vbus be an active low
signal. Both options are set in the platform data for the device.

This rework allows to address tow memory controllers. AT91SAM9263 and
AT91SAM9G45 family have tow SDRAM or DDR/SDRAM controllers. Power management
should take care of this.
This patch modify the way RAM IP header files are implemented to allow
access to registers of both controllers ; it also adds some macros.
We also modify the power management files to use those modified header files.
Slow clock (assembly) and regular power management functions are synchronized
for setting of RAM self-refresh procedure:
(lpr & ~AT91_DDRSDRC_LPCB) | AT91_DDRSDRC_LPCB_SELF_REFRESH
Note that AT91RM9200 is not impacted by this modification.

Disable the processor clock when the CPU is idle.
This saves much more power than merely entering 'Wait for Interrupt' mode.
Since JTAG-debugging doesn't work when the processor clock is switched off,
make it conditional on CONFIG_DEBUG_KERNEL.

AT91: when turning off the PLLs during suspend, don't wait for the lock
flag to be set. Previously the code would always run into the loop
limitation of 1000 iterations because the flag is never set when turning
the PLLs off.

at91 slow-clock resume: Don't wait for a disabled PLL to lock.
We run into this problem with the PLLB on the at91: ohci-at91 disables
the PLLB when going to suspend. The slowclock code however tries to do
the same: It saves the PLLB register value and when restoring the value
during resume, it waits for the PLLB to lock again. However the PLL will
never lock and the loop would run into its timeout because the slowclock
code just stored and restored an empty register.
This fixes the problem by only restoring PLLA/PLLB when they were enabled
at suspend time.

We can use r1 for tmp register for both head.S and debug.S.
NOTE: This patch depends on another patch to add the the tmp register
into all debug-macro.S files. That can be done with:

on AT91 the timer irq is shared, so the handler might be entered without
irqs being disabled. Though this should not happen as the timer irq is
registered early, there have been some reports on the mailing list.
To make debugging that problem easier next time it pops up a
WARN_ON_ONCE is added to the handler if irqs are not off.

Allow the use of another DMA controller driver in atmel-mci sd/mmc driver.
This adds a generic dma_slave pointer to the mci platform structure where
we can store DMA controller information. In atmel-mci we use information
provided by this structure to initialize the driver (with new helper
functions that are architecture dependant).
This also adds at32/avr32 chip modifications to cope with this new access
method.
