DRA7 Data Manual (SPRS857L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions".
This implies that all unused voltage rails for Vayu can never be
switched off even if the hardware blocks inside that voltage domain is
unused. Switching off these unused rails may result in stability issues
on other domains and increased leakage and power-on-hour impacts.
J6eco-evm dts file already considers this, however j6evm-dts file needs
to be fixed to consider this constraint of the SoC.

Add MMC1 and 2 nodes. MMC1 is SDcard and MMC2 is eMMC.
NOTE on MMC1 card detect: Ideally, we should be using in-built SDCD
support, but we dont have it yet. So, use the fact that control module
of DRA7 is setup such that no matter what mode one configures it, GPIO
option is always hardwired in - use GPIO mode for SDcard detection.

The power line feeding the SD card is also used by other devices on the EVM.
Use generic name instead of mmc2_3v3 so when other devices want to use the

Looks like we have some GPMC NAND timings missing device

errors during boot.
Signed-off-by: Tony Lindgren <tony@atomide.com>
With the GPMC warnings now enabled, I noticed the LAN9220 timings
can overflow the GPMC registers with 200MHz L3 speed. Earlier we
were just skipping the bad timings and would continue with the
bootloader timings. Now we no longer allow to continue with bad
timings as we have the timings in the .dts files.
We could start using the GPMC clock divider, but let's instead
use the u-boot timings that are known to be working and a bit
faster. These are basically the u-boot NET_GPMC_CONFIG[1-6]
defines deciphered. Except that we don't set gpmc,burst-length
as that's only partially configured and does not seem to work
if fully enabled.

The four port serial port on the zoom debug board uses a TL16CP754C
with a single interrupt and GPMC chip select. The serial ports each
use a 8 bytes for IO registers, and are 256 bytes apart on the GPMC
line.
Let's add timings for all four ports so we can remove the GPMC
workarounds for using bootloader timings.
Not caused by this patch, but looks like u-boot only properly
initializes the fifo on the first serial port. Currently the other
ports produce garbage at least with my version of u-boot. I suspect
that TL16CP754C needs non-standard initialization added to 8250
driver to properly fix this issue.

The GPMC binding is obviously very confusing as the values
are all over the place. People seem to confuse the GPMC partition
size for the chip select, and the device IO size within the GPMC
partition easily.
The ranges entry contains the GPMC partition size. And the
reg entry contains the size of the IO registers of the
device connected to the GPMC.
Let's fix the issue according to the following table:
Device GPMC partition size Device IO size

16550 0x01000000 (16MB) 8

Commit 78b81f4666 ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
when doing the following sequence in loop:
- Boot the kernel
- Perform audio playback
- Reboot the system via 'reboot' command
In many times the audio card cannot be probed, which causes playback to fail.
After restoring to the original i2c0 frequency of 100kHz there is no such
problem anymore.

Pull clock tree updates from Mike Turquette:
"The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers.
This tag contains a bit more arch code than I usually take due to some
OMAP2+ changes. Additionally it contains the restart notifier
handlers which are merged as a dependency into several trees.
The PXA changes are the only messy part. Due to having a stable tree
I had to revert one patch and follow up with one more fix near the tip
of this tag. Some dead code is introduced but it will soon become
live code after 3.18-rc1 is released as the rest of the PXA family is
converted over to the common clock framework.
Another trend in this tag is that multiple vendors have started to
push the complexity of changing their CPU frequency into the clock
driver, whereas this used to be done in CPUfreq drivers.
Changes to the clk core include a generic gpio-clock type and a
clk_set_phase() function added to the top-level clk.h api. Due to
some confusion on the fbdev mailing list the kernel boot parameters
documentation was updated to further explain the clk_ignore_unused
parameter, which is often required by users of the simplefb driver.
Finally some fixes to the locking around the clock debugfs stuff was
done to prevent deadlocks when interacting with other subsystems."
