      ARM: OMAP4: hwmod data: Force HDMI in no-idle while enabled · dc57aef5
      Ricardo Neri authored 
      As per the OMAP4 documentation, audio over HDMI must be transmitted in
no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses
no-idle/force-idle settings instead of smart-idle mode.

This is required as the DSS interface clock is used as functional clock
for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could
be choppy, have bad quality or not be audible at all.

      Commit bbd707ac ("ARM: omap2: use
machine specific hook for late init") resulted in the addition of this
sparse warning:

arch/arm/mach-omap2/mux.c:791:12: warning: symbol 'omap_mux_late_init' was not declared. Should it be static?

Fix by including the header file containing the prototype.

      ARM: OMAP2+: CM: increase the module disable timeout · b8f15b7e
      Paul Walmsley authored 
      Increase the timeout for disabling an IP block to five milliseconds.
This is to handle the usb_host_fs idle latency, which takes almost
four milliseconds after a host controller reset.

This is the second of two patches needed to resolve the following
boot warning:

omap_hwmod: usb_host_fs: _wait_target_disable failed

      ARM: OMAP4: clock data: add clockdomains for clocks used as main clocks · 9a47d32d
      Paul Walmsley authored 
      Until the OMAP4 code is converted to disable the use of the clock
framework-based clockdomain enable/disable sequence, any clock used as
a hwmod main_clk must have a clockdomain associated with it.  This
patch populates some clock structure clockdomain names to resolve the
following warnings during kernel init:

omap_hwmod: dpll_mpu_m2_ck: missing clockdomain for dpll_mpu_m2_ck.
omap_hwmod: trace_clk_div_ck: missing clockdomain for trace_clk_div_ck.
omap_hwmod: l3_div_ck: missing clockdomain for l3_div_ck.

      ARM: OMAP: Fix Beagleboard DVI reset gpio · aef2b896
      Russ Dill authored 
      Commit e813a55e ("OMAP: board-files:
remove custom PD GPIO handling for DVI output") moved TFP410 chip's
powerdown-gpio handling from the board files to the tfp410 driver. One
gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in
the Beagle board file. This causes the tfp410 driver to fail to request
the gpio on Beagle, causing the driver to fail and thus the DVI output
doesn't work.

This patch removes several boot errors from board-omap3beagle.c:

 - gpio_request: gpio--22 (DVI reset) status -22
 - Unable to get DVI reset GPIO

There is a combination of leftover code and revision confusion.
Additionally, xM support is currently a hack.

For original Beagleboard this removes the double initialization of GPIO
170, properly configures it as an output, and wraps the initialization
in an if block so that xM does not attempt to request it.

For Beagleboard xM it removes reference to GPIO 129 which was part
of rev A1 and A2 designs, but never functioned. It then properly assigns
beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the
hack of initializing it high. Additionally, it uses
gpio_set_value_cansleep since this GPIO is connected through i2c.

Unfortunately, there is no way to tell the difference between xM A2 and
A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL
GPIO used on A3 and beyond is not used on rev A1 and A2, there are no
problems created by this fix.

Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4.

      ARM: OMAP2+: Fix MUSB ifdefs for platform init code · 310018d5
      Tony Lindgren authored 
      Commit 62285963 (usb: musb: drop a gigantic amount of ifdeferry)
got rid of a bunch of ifdefs in the MUSB code. Looks like the
platform init code is still using these dropped defines though,
which in many cases results the board defaulting always to host
mode.

Currently the situation is that USB_MUSB_HDRC is the main
Kconfig option with additional USB_GADGET_MUSB_HDRC so only
these two should be used to select between host and OTG mode.

Fix the situation for omaps. The following users should fix the
platform init code in a similar way:

Dropped Kconfig option          Current users

USB_MUSB_OTG                    blackfin, davinci, not in Kconfigs
USB_MUSB_PERIPHERAL             davinci, not in Kconfigs
USB_MUSB_HOST                   davinci, not in Kconfigs

      Commit a5302572 (OMAP: Add debugfs
node to show the summary of all clocks) introduced clock summary,
however, we are interested in seeing snapshot of the clock state, not
in dynamically changing clock configurations as the data provided by
clock summary will then be useless for debugging configuration
issues. So, hold the common lock when dumping the clock summary.

      ARM: Kirkwood: Fix clk problems modular ethernet driver · 128789a8
      Andrew Lunn authored 
      When the ethernet driver was built as a module, it would lock the
machine when loaded. At boot the ethernet clks are unused, so get
turned off.  Later, when the module is loaded, the probe function
would access the hardware before the clock was restarted, and the
machine would lock. It has also been determined that when the clk is
turned off, the interface forgets its MAC address, which for most
systems, is set by the boot loader.

When the machine setup file creates a platform device for the
interface, prepare and enable the clock for the interface. This will
ensure it is not turned off. However, if the setup file only
instantiates one platform device, the other will have its clk
disabled, thus maybe saving a little power.

      arm: versatile: fix and enable PCI I/O space · 9b0f7e39
      Arnd Bergmann authored 
      With commit 4d5fc58d (ARM: remove bunch of now unused
mach/io.h files), the I/O space setup was completely broken on
versatile. This patch fixes that and prepares for further
I/O space clean-up.

I/O space handling on the versatile platform is currently
broken in multiple ways. Most importantly, the ports do
not get mapped into the virtual address space at all.

Also, there is some amount of confusion between PCI I/O
space and other statically mapped MMIO registers in the
platform code:

* The __io_address() macro that is used to access the
  platform register maps to the same __io macro that gets
  used for I/O space.

* The IO_SPACE_LIMIT is set to a value that is much larger
  than the total available space.

* The I/O resource of the PCI bus is set to the physical
  address of the mapping, which is way outside of the
  actual I/O space limit as well as the address range that
  gets decoded by traditional PCI cards.

* No attempt is made to stay outside of the ISA port range
  that some device drivers try access.

* No resource gets requested as a child of ioport_resource,
  but an IORESOURCE_IO type mapping gets requested
  as a child of iomem_resource.

This patch attempts to correct all of the above. This makes
it possible to use virtio-pci based virtual devices as well
as actual PCI cards including those with legacy ISA port
ranges like VGA.

Some of the issues seem to be duplicated on other platforms.
