13d5e27a44 davinci: DA850/OMAP-L138: avoid using separate initcall for initializing regulator
Using a device_initcall() for initializing the voltage regulator
on DA850 is not such a good idea because it gets called for all
platforms - even those who do not have a regulator implemented.
This leads to a big fat warning message during boot-up when
regulator cannot be found.

Instead, tie initialization of voltage regulator to cpufreq init.
Define a platform specific init call which in case of DA850 gets
used for initializing the regulator. On other future platforms it
can be used for other purposes.

a6c0f6eca1 davinci: add CPU idle driver
The patch adds support for DaVinci cpu idle driver.

Two idle states are defined:
1. Wait for interrupt
2. Wait for interrupt and DDR self-refresh (or power down)

Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467)
while others support putting DDR in self-refresh and power down (eg DM35x,
DA8xx).

Putting DDR (or mDDR) in power down saves more power than self-refresh.

The patch has been tested on DA850/OMAP-L138 EVM.

1ef203c324 davinci: DA8XX/OMAP-L1XX: fix compiler warning
When kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y
option, using da8xx_omapl_defconfig, some warnings are
observed:

WARNING: vmlinux.o(.text+0xc2a4): Section mismatch in reference
from the function da850_evm_setup_nor_nand() to the variable
.init.data:da850_nand_pins
The function da850_evm_setup_nor_nand() references
the variable __initdata da850_nand_pins.
This is often because da850_evm_setup_nor_nand lacks a __initdata
annotation or the annotation of da850_nand_pins is wrong.

This patch fixes such warnings.

bae105879f davinci: DA850/OMAP-L138 EVM: implement autodetect of RMII PHY
Implement autodetection of RMII PHY by shifting the decision
to use the RMII PHY to da850_evm_ui_expander_setup() from
da850_evm_init() earlier.

Without this patch, selecting RMII PHY in the UI expander menu
will make the MII PHY unusable even though UI board is not
connected.

The actual configuration and registration of the EMAC device
is delayed to device_initcall() so it happens after the UI card
detection is complete.

A side effect of this patch is the removal of a voilation of

2206771c43 davinci: RMII support for DA850/OMAP-L138 EVM
DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY
is enabled by proper programming of the IO Expander (TCA6416) ports. Also for
RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the
PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds
support for RMII PHY.

This patch also adds a menuconfig option to select one or no peripheral
connected to expander. Currently, sub-options in this menu are RMII and no
peripheral.This menuconfig option is similar to the one present for UI card on
DA830/OMAP-L137 EVM.

683b1e1f0e davinci: DA850/OMAP-L138: add frequency scaling support
Adds basic frequency scaling support for DA850/OMAP-L138.

Currently, frequency scaling only on PLL0 is supported. No scaling of PLL1
as yet.

Peripherals like MMC/SD which have a clock input synchronous with
ARM clock will not work well since the clock will change behind their backs.
Support for notification to such devices to adjust themselves to the
new frequency will be added in later patches. Current defconfigs keep
CPUFreq disabled so it will not affect normal operation.

The OPP defintions assume clock input of 24MHz to the SoC. This is inline
with hardcoding of input frequency in the <soc>.c files. At some point
this will need to move into board dependent code as new boards appear with
a different reference clock.

Tested on OMAP-L138 EVM with ondemand governer and a shell script to
vary processor load.

When checking to see if the starting slot is a valid number,
it checks to make sure that the "_ANY" option is not used.

7761ef6793 davinci: Correct the GPIO number for LCD panel power
On the latest DA850/OMAP-L138 EVM (Beta) the GPIO pin
number of LCD panel power has changed. This patch takes
care of this change. Software will support only Beta
versions of DA850/OMAP-L138 EVM.

In the process, add the missing entry for data pin 0
and remove the GPIO specific pins from da850_lcdcntl_pins
structure. EVM specific muxing for LCD is being done in the
board file now.

Add graphics support for the Sharp LCD035Q3DG01 graphical
LCD that's on the User Interface (UI) daughter card of the
DA830/OMAP-L137 EVM.

The LCD shares EMIFA lines with the NAND and NOR devices that
are also on the UI card so those lines are shared via a couple
of muxes.  The muxes are controlled by the 'MUX_MODE' line on
the UI card.  The 'MUX_MODE' line is controlled by pin P6 of
a pcf8574 i2c expander that's at i2c address 0x3f on UI card.
The i2c expander is controlled using the gpio infrastructure
from the board code using the 'setup()' and 'teardown()'
routines.

clk_round_rate, clk_set_rate have been updated to handle dynamic

The motivation behind the changes is to support dynamic CPU frequency

davinci_set_pllrate() changes the PLL rate of a given PLL. This function
has been presented as a generic function though it has been tested only
on OMAP-L138 EVM. No other currently available DaVinci device will probably
use this function, but any future device specific changes will hopefully be
small enough to get taken care using a cpu_is_xxx() macro.

There is no need to pass clock name strings in platform_data.

5a4b131508 davinci: Add EMAC support for da850/omap-l138
Ethernet Media Access Controller (EMAC) on da850/omap-l138
supports 10/100 Mbps operation. It also supports Media
Independent Interface (MII) and Reduced Media Independent
Interface (RMII) to physical layer (PHY).

Phy which supports MII is present on the DA850/OMAP-L138
base board and Phy supporting RMII is present on the
UI card. This patch adds support only for the MII Phy.
Support for RMII Phy will be added later.

0fbc559215 davinci: Add support for DA850/OMAP-L138 EVM board
Add support for the DA850/OMAP-L138 Evaluation Module (EVM)
from TI.  The EVM has User Interface (UI) card which contains
various devices. This UI card can be connected to the base
board. Support for all the devices on the UI card and ones on
the EVM will be added in subsequent patches.

The EVM schematics are not available publicly yet; but should
be available soon.

A new defconfig for this board has been added mainly because
the DA830/OMAP-L137 defconfig forces writethrough cache mode
which is not required on DA850/OMAP-L138.

This patch has been boot tested on DA850/OMAP-L138 EVM
using ramdisk as filesystem.

The DA850/OMAP-L138 is a new SoC from TI in the same family as
DA830/OMAP-L137.

Major changes include better support for power management,
support for SATA devices and McBSP (same IP as DM644x).

This patch adds platform data and init function for IDE which could be called
from board specific file to register IDE device.

Note that for 594MHz device the transfer mode is limited to UDMA4 since ideclk
rate is less than 100 MHz, which forces udma_mask in palm_bk3710.c to UDMA4,
while for 729MHz device, it is UDMA5.
