When a failure to stop a module in the pipeline is detected, the only
way to recover is to reset the ISP. However, as other users can be using
a different pipeline with other modules, the ISP can't be reset
synchronously with the error detection.
Mark the ISP as needing a reset when a failure to stop a pipeline is
detected, and reset the ISP when the last user releases the last
reference to the ISP.
Modify the omap3isp_pipeline_set_stream() function to record the new ISP
pipeline state only when no error occurs, except when stopping the
pipeline in which case the pipeline is still marked as stopped.

Apparently some distros set i2c-algo-bit.bit_test to 1 by
default. In some cases this causes i2c_bit_add_bus
to fail and prevents the i2c bus from being added. In the
radeon case, we fail to add the ddc i2c buses which prevents
the driver from being able to detect attached monitors.
The i2c bus works fine even if bit_test fails. This is likely
due to gpio switching that is required and handled in the
pre/post_xfer hooks, so call the pre/post_xfer hooks in the
bit test as well.

This patch fixes a regression introduced by
fd3cc69848
"viafb: remove duplicated clock storage"
caused by an incosistent mode which pretended to have a higher
refresh rate than it actually had. The wrong refresh rate resulted
in a calculated higher pixclock which the OLPC DCON could not handle.
By reducing the refresh rate to 50Hz we get close to the old
pixclock which makes the OLPC display usable again.
Minor other adjustments are needed as 60Hz is assumed to be a safe
value which is not true for OLPC DCON. This is no problem as we only
support 1200x900 on the OLPC.

dss.lcd_clk_source is set to the default value DSS_CLK_SRC_FCK at dss_init.
For OMAP2 and OMAP3, the dss.lcd_clk_source should always be the same as
dss.dispc_clk_source. The function dss_get_lcd_clk_source() always returns the
default value DSS_CLK_SRC_FCK for OMAP2/3. This leads to wrong clock dumps when
dispc_clk_source is not DSS_CLK_SRC_FCK.

On OMAP4, reading DSI_PLL_CONFIGURATION2 register requires the L3 clock
(CIO_CLK_ICG) to PLL. Currently dsi_dump_clocks() tries to read that
register without enabling the L3 clock, leading to crash if DSI is not
in use.
The status of the bit being read from DSI_PLL_CONFIGURATION2 is
available from dsi_clock_info->use_sys_clk, so we can avoid the whole
problem by just using that.

When physical identification of an adapter is done by toggling the
mechanism on and off through software utilizing the set_phys_id operation,
it is done with a fixed duration for both on and off states. Some drivers
may want to set a custom duration for the on/off intervals. This patch
changes the API so the return code from the driver's entry point when it
is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to
cycle the on/off states, and updates the drivers that have already been
converted to use the new set_phys_id and use the synchronous method for
identifying an adapter.
The physical identification frequency set in the updated drivers is based
on how it was done prior to the introduction of set_phys_id.
Compile tested only. Also fixes a compiler warning in sfc.

Broadcom iscsi offload firmware uses a non standard ibft sign of "BIFT".
When we added support for boot, the anaconda team and I were using
older firmware (I guess 4 years old), so boot does not work on current
cards.
This patch modifies the ibft search code to search for "BIFT" along
with the other possible values.
Broadcom has tested the patch and reported it works with their
firmware. Mike has tested Chelsio and Intel cards.
