[PATCH V2 0/4] ARM: OMAP2+: Timer build warnings and error fixes

[Jon Hunter]

Fixes for build warnings and errors seen with various kernel
configuration combinations. Based upon Tony Lindgren's OMAP
master branch.

V2 changes:
- Update fix for realtime counter per feedback from Santosh
- Update fix when building for only AM335x with Igor's suggestion to
  use __maybe_unused (thanks Igor!)
- Add Vaibhav's fixes for sparse warnings

Jon Hunter (3):

[PATCH V2 1/4] ARM: OMAP2+: Fix realtime_counter_init warning in timer.c

[Jon Hunter]

In commit fa6d79d (ARM: OMAP: Add initialisation for the real-time
counter), the function realtime_counter_init() was added. However, if
the kernel configuration option CONFIG_SOC_OMAP5 is not selected then
the following compiler warning is observed.

  CC      arch/arm/mach-omap2/timer.o
  arch/arm/mach-omap2/timer.c:489:20: warning: ‘realtime_counter_init’
  defined but not used [-Wunused-function]

Commit fa6d79d also introduced the kernel configuration option
CONFIG_SOC_HAS_REALTIME_COUNTER. If this option is not selected then the
a stub function for realtime_counter_init() is defined.

For non-OMAP5 devices, there is no realtime counter and so
realtime_counter_init() function and stub function are not used for
these devices. Therefore, fix this warning by only allowing the kernel
configuration option CONFIG_SOC_HAS_REALTIME_COUNTER to be enabled for
OMAP5 devices.

[PATCH V2 2/4] ARM: OMAP4: Fix build error and warning in timer.c

[Jon Hunter]

When compiling the kernel with configuration option CONFIG_ARCH_OMAP4
enabled and CONFIG_LOCAL_TIMERS disabled, the following build error and
warning is seen.

  CC      arch/arm/mach-omap2/timer.o
  arch/arm/mach-omap2/timer.c: In function ‘omap4_local_timer_init’:
  arch/arm/mach-omap2/timer.c:630:2: error: implicit declaration of
  	function ‘omap4_sync32_timer_init’

  	defined but not used [-Wunused-function]
  cc1: some warnings being treated as errors
  make[1]: *** [arch/arm/mach-omap2/timer.o] Error 1

This issue was introduced by commit 6f80b3b (ARM: OMAP2+: timer: remove
CONFIG_OMAP_32K_TIMER) where the "k" is missing from the "sync32k" in
the function name "omap4_sync32_timer_init". Therefore, correct this
typo to resolve the above error and warning.

[PATCH V2 3/4] ARM: AM335x: Fix warning in timer.c

[Jon Hunter]

When compiling the kernel with configuration options ...

 # CONFIG_ARCH_OMAP2 is not set
 # CONFIG_ARCH_OMAP3 is not set
 # CONFIG_ARCH_OMAP4 is not set
 # CONFIG_SOC_OMAP5 is not set
 CONFIG_SOC_AM33XX=y

 ... the following build warning is seen.

  arch/arm/mach-omap2/timer.c:395:19: warning: ‘omap2_sync32k_clocksource_init’
  	defined but not used [-Wunused-function]

This issue was introduced by commit 6f80b3b (ARM: OMAP2+: timer: remove
CONFIG_OMAP_32K_TIMER) where the omap2_sync32k_clocksource_init() is no
longer referenced by the timer initialisation function for the AM335x
device as it has no 32k-sync timer.

Fix this by adding the "__maybe_unused" compiler directive to the
omap2_sync32k_clocksource_init() function to indicate that this function
may be used for certain configurations.
