I no longer work at Bluewater Systems. Update my email address accordingly. I
have deleted my email address from C files rather than change it. This
was suggested by several people, since the commit from my new email
address will cause scripts/get_maintainer.pl to function properly. I
have not added the .mailmap entry as suggested by Joe because I think
it is no longer necessary if I touch all the files which had my name

The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface
peripheral. At power-up they default into non-GPIO mode with the Key
Matrix controller enabled so these ports are unusable for GPIO. Note
that the Keypad Interface peripheral is only available in the EP9307,
EP9312, and EP9315 processor variants.
The keypad support will clear the DeviceConfig bits appropriately to
enable the Keypad Interface when the driver is loaded. And, when the
driver is unloaded it will set the bits to return the ports to GPIO mode.
To make these ports available for GPIO after power-up on all EP93xx
processor variants, set the KEYS and GONK bits in the DeviceConfig
register.
Similarly, the E, G, and H ports are multiplexed with the IDE Interface
peripheral. At power-up these also default into non-GPIO mode. Note
that the IDE peripheral is only available in the EP9312 and EP9315
processor variants.
Since an IDE driver is not even available in mainline, set the EONIDE,
GONIDE, and HONIDE bits in the DeviceConfig register so that these
ports will be available for GPIO use after power-up.

Rather than checking the MMU status in every instance of addruart, do it

return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU

When channel_disable() is called, it disables per channel interrupts and
waits until channels state becomes STATE_STALL, and then disables the
channel. Now, if the DMA transfer is disabled while the channel is in
STATE_NEXT we will not wait anything and disable the channel immediately.
This seems to cause weird data corruption for example in audio transfers.
Fix is to wait while we are in STATE_NEXT or STATE_ON and only then
disable the channel.

Commit 7cfe24947 ("ARM: AMBA: Add pclk support to AMBA bus

However, in EP93xx clock initialization is arch_initcall which is done
later than AMBA device identification. This causes
amba_get_enable_pclk() to fail resulting device where UARTs are not
functional.
So change ep93xx_clock_init() to be postcore_initcall.

This patch extends the ASoC API to allow sound cards to have more than one
CODEC and more than one platform DMA controller. This is achieved by dividing
some current ASoC structures that contain both driver data and device data into
structures that only either contain device data or driver data. i.e.
struct snd_soc_codec ---> struct snd_soc_codec (device data)
+-> struct snd_soc_codec_driver (driver data)
struct snd_soc_platform ---> struct snd_soc_platform (device data)
+-> struct snd_soc_platform_driver (driver data)
struct snd_soc_dai ---> struct snd_soc_dai (device data)
+-> struct snd_soc_dai_driver (driver data)
struct snd_soc_device ---> deleted
This now allows ASoC to be more tightly aligned with the Linux driver model and
also means that every ASoC codec, platform and (platform) DAI is a kernel
device. ASoC component private data is now stored as device private data.
The ASoC sound card struct snd_soc_card has also been updated to store lists
of it's components rather than a pointer to a codec and platform. The PCM
runtime struct soc_pcm_runtime now has pointers to all its components.
This patch adds DAPM support for ASoC multi-component and removes struct
snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
or runtime PCM level basis rather than using snd_soc_socdev.
Other notable multi-component changes:-
* Stream operations now de-reference less structures.
* close_delayed work() now runs on a DAI basis rather than looping all DAIs
in a card.
* PM suspend()/resume() operations can now handle N CODECs and Platforms
per sound card.
* Added soc_bind_dai_link() to bind the component devices to the sound card.
* Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
DAI link components.
* sysfs entries can now be registered per component per card.
* snd_soc_new_pcms() functionailty rolled into dai_link_probe().
* snd_soc_register_codec() now does all the codec list and mutex init.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform driver
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().

This patch adds platform side support code for the EP93xx SPI
driver. This includes clock, resources and muxing. There is a new
function: ep93xx_register_spi() which can be used by board support
code to register new SPI devices for the board.

A number of the peripherals for the ep93xx are registered at
startup using platform_data that is passed from the board init
code to the core code. This data is then copied to a local
static variable in the core code. Since the data is copied,
the original data can be marked as __initdata and discarded
after startup is complete.
This adds the __initdata tag to all the appropriate data in
the various ep93xx board init's. Specifically, all the
struct ep93xx_eth_data, struct ep93xxfb_mach_info, and
struct i2c_gpio_platform_data.
Also, document the various registration functions and note
what data should be marked as __initdata.
While here, also cleanup a couple over zealous whitespace tabs.

The GPIO support in core.c handles the interrupt support for GPIO
ports A, B, and F. The gpiolib implementation in gpio.c needs to
access the function ep93xx_gpio_int_mask when a gpio pin is made
an output and ep93xx_gpio_update_int_params in order to update
the registers.
Moving this support from core.c to gpio.c allows making the two
functions static. It also keeps all the GPIO handling together in one
file.

The clock generation system in the ep93xx uses two external oscillator's
and two internal PLLs to derive all the internal clocks. Many of these
internal clocks can be stopped to save power.
This introduces a "parent" hierarchy for the clocks so that the users
count can be correctly tracked for power management.
The "parent" for the video clock can either be one of the PLL outputs
or the external oscillator. In order to correctly track the "parent"
for the video clock calc_clk_div() needed to be modified. It now
returns an error code if the desired rate cannot be generated.

sda and scl pins. It also allows the platform to specify the
udelay and timeout.
2) Program the gpio configuration register to enable/disable the

sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and
EP93XX_GPIO_LINE_EECLK.

Add clkdev support for the ep93xx_keypad driver.
A matrix keypad driver for the ep93xx just got merged via the
input subsystem group. For this driver to work the keypad clock
needs to be added to the ep93xx clkdev support. In order to
accomplish this the following changes are implemented:
1) Move the EP93XX_EXT_*_RATE defines to mach/include/hardware.h.
2) Add EP93XX_KEYTCHCLK_DIV{4/16} for the keypad driver.
3) Add support for programmable clocks (set_rate() callback).
4) Add clk_keypad for the keypad driver.
5) tab indent the clk_lookup table for easier reading.
6) Add the set_rate() callback to program the keypad clock.
This callback is generalized since the ADC clock (touchscreen)
can use the same callback.

Add core functions to handle writes to the ep93xx software locked
registers.
There are a number of registers in the EP93xx System Controller
that require a write to the software lock register before they
can be updated. This patch adds a number of exported functions
to the ep93xx core that handle this access.
The software locked clock divider registers, VidClkDiv, MIRClkDiv,
I2SClkDiv and KeyTchClkDiv would typically involve writing a
specific value to the register. To support this the
ep93xx_syscon_swlocked_write() function is provided.
For the DeviceCfg register it's more typical to only need to
set or clear a single bit. A generic ep93xx_devcfg_set_clear()
function is provided to handle both operations. Two inline
functions, ep93xx_devcfg_set_bits() and ep93xx_devcfg_clear_bits()
are also provided to improve code readability.
In addition, the remaining bits in the System Controller Device
Config Register have been documented and the previously defined
names shortened.
All code paths that use this functionality have been updated
except for arch/arm/kernel/crunch.c. That code is in a context
switch path, which is not reentrant, so it is safe against itself.

Update the dma clocks so that the magic numbers are named.
All the dma clocks have an enable bit to turn them on/off as
needed. Currently these bits are in the code as "magic"
numbers. This changes all of them to named defines to
improve code readability.
Also, the EP93XX_SYSCON_CLOCK_CONTROL register is improperly
named. In the EP93xx User's Guide this register is called
PwrCnt (Power Control). All of the uses of this register
are associated with the clock support so this patch also
modifies the names to match the User's Guide.

This patch adds a Kconfig option to select between ep93xx boards which
boot from the SDRAM bank at 0x00000000 (SDCE3/SyncBoot) and those which
boot from 0xc0000000 (SDCE0). This corrects a problem which causes
invalid images to be built for boards which boot from 0xc0000000.

Fix the clkdev API support for the ep93xx uart clocks.
The uarts available in the ep93xx have individual clock controls.
The current implementation assumes that the bootloader has enabled
the clocks before the kernel has booted. It also assumes that the
bootloader has set the UARTBAUD bit indicating that the uarts are
running off the 14.7456MHz external crystal.
This fixes both issues. It also allows the uart clocks to be stopped
when there are no users.

Add power management support to the VIC by registering
each VIC as a system device to get suspend/resume
events going.
Since the VIC registeration is done early, we need to
record the VICs in a static array which is used to add
the system devices later once the initcalls are run. This
means there is now a configuration value for the number
of VICs in the system.

Update the rtc-ep93xx driver to use ioremap'ed addresses.
This removes the dependency on <mach/hardware.h> and properly
reports the memory addresses used by the driver in /proc/iomem.
In addition, ep93xx_rtc_init() is updated to use
platform_driver_probe() instead of platform_driver_register().
Also, the device_create_file() calls are now properly checked for
error conditions. The created sysfs files are also now removed
when the driver is removed.

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not. There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().
This patch fixes things to pass this string to arch_reset(). This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.
