build some drivers only when compile-testing

2013-06-24T23:41:32+00:00

Some drivers can be built on more platforms than they run on. This is
a burden for users and distributors who package a kernel. They have to
manually deselect some (for them useless) drivers when updating their
configs via oldconfig. And yet, sometimes it is even impossible to
disable the drivers without patching the kernel.

Introduce a new config option COMPILE_TEST and make all those drivers
to depend on the platform they run on, or on the COMPILE_TEST option.
Now, when users/distributors choose COMPILE_TEST=n they will not have
the drivers in their allmodconfig setups, but developers still can
compile-test them with COMPILE_TEST=y.

Now the drivers where we use this new option:
* PTP_1588_CLOCK_PCH: The PCH EG20T is only compatible with Intel Atom
  processors so it should depend on x86.
* FB_GEODE: Geode is 32-bit only so only enable it for X86_32.
* USB_CHIPIDEA_IMX: The OF_DEVICE dependency will be met on powerpc
  systems -- which do not actually support the hardware via that
  method.
* INTEL_MID_PTI: It is specific to the Penwell type of Intel Atom
  device.

[v2]
* remove EXPERT dependency

[gregkh - remove chipidea portion, as it's incorrect, and also doesn't
 apply to my driver-core tree]

pch_gbe, ptp_pch: Fix the dependency direction between these drivers

2012-11-18T03:11:45+00:00

In commit a24006ed12616bde1bbdb26868495906a212d8dc ('ptp: Enable clock
drivers along with associated net/PHY drivers') I wrongly made
PTP_1588_CLOCK_PCH depend on PCH_GBE.  The dependency is really the
other way around.  Therefore make PCH_GBE select PTP_1588_CLOCK_PCH
and remove the 'default y' from the latter.

ptp: Enable clock drivers along with associated net/PHY drivers

2012-11-01T15:35:18+00:00

Where a PTP clock driver is associated with a net or PHY driver, it
should be enabled automatically whenever that driver is enabled.
Therefore:

- Make PTP clock drivers select rather than depending on PTP_1588_CLOCK
- Remove separate boolean options for PTP clock drivers that are built
  as part of net driver modules.  (This also fixes cases where the PTP
  subsystem is wrongly forced to be built-in.)
- Set 'default y' for PTP clock drivers that depend on specific net
  drivers but are built separately

ptp: Make PTP_1588_CLOCK select rather than depend on PPS

2012-11-01T15:35:18+00:00

PTP hardware clock drivers that select PTP_1588_CLOCK must currently
also select PPS.  For those drivers that don't, the user must enable
PPS, then enable PTP_1588_CLOCK, then the driver.  Simplify things for
developers and users by putting this selection in one place.

pps, ptp: Remove dependencies on EXPERIMENTAL

2012-11-01T15:35:17+00:00

These are now established subsystems, and we want drivers to be able
to select PPS and PTP_1588_CLOCK without depending on EXPERIMENTAL.
Further, the use of EXPERIMENTAL is now deprecated in general.

pch_gbe: correct receive time stamp filtering

2012-04-21T19:27:45+00:00

This patch fixes the driver so that multicast PTP event messages can
be recognized by the hardware time stamping unit. The station address
register must be set according to the desired transport type.

[ RC - Rebased Takahiro's changes and wrote a commit message
  explaining the changes. ]
