ARM: omap: fix missing declaration warnings

2022-04-29T07:53:28+00:00

Moving the plat-omap files triggered a sparse warning for omap1 and omap2 that is now in a different file from before. Found some more sparse warnings here that I address by making sure the declaration is visible to both the caller and the callee, or they are static mach-omap1/fb.c:33:17: warning: symbol 'omap_fb_resources' was not declared. Should it be static? mach-omap1/timer32k.c:215:12: warning: symbol 'omap_init_clocksource_32k' was not declared.

ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF

2022-04-22T09:08:55+00:00

In preparation for conversion of OMAP1 clocks to common clock framework, identify arch/arm/mach-omap1 local users of those clocks and update them to call clk_prepare_enable/clk_disable_unprepare() instead of just clk_enable/disable(), as required by CCF implementation of clock API.

ARM: omap1: move mach/*.h into mach directory

2022-04-22T09:08:55+00:00

Most of the header files are no longer referenced from outside arch/arm/mach-omap1, so move them all to that place directly and change their users to use the new location. The exceptions are: - mach/compress.h is used by the core architecture code - mach/serial.h is used by mach/compress.h The mach/memory.h is empty and gets removed in the process, avoiding the need for CONFIG_NEED_MACH_MEMORY_H.

ARM: omap1: move 32k counter from plat-omap to mach-omap1

2022-04-21T13:01:47+00:00

omap2 stopped using this code with commit 8d39ff3d1696 ("ARM: OMAP2+: Remove unused legacy code for timer"), so just move it to mach-omap1 now, along with the other half of that driver. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: OMAP: replace setup_irq() by request_irq()

2020-03-04T16:30:30+00:00

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq().

ARM/omap1/timer32: Migrate to new 'set-state' interface

2015-07-17T02:58:39+00:00

Migrate omap timer32 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. Acked-by: Santosh Shilimkar Acked-by: Tony Lindgren Signed-off-by: Viresh Kumar

ARM: OMAP1: timer32k.c: Remove unused function

2015-01-07T17:53:51+00:00

Remove the function omap_32k_timer_read() that is not used anywhere. This was partially found by using a static code analysis program called cppcheck. Signed-off-by: Rickard Strandqvist Signed-off-by: Tony Lindgren

ARM: OMAP: remove deprecated IRQF_DISABLED

2013-10-03T20:24:36+00:00

ARM: use clockevents_config_and_register() where possible

2013-01-14T18:12:42+00:00

The clockevent core is able to figure out the best mult and shift, calculate min_delta_ns and max_delta_ns, with the necessary info passed into clockevents_config_and_register(). Use this combined configure and register function where possible to make the codes less error prone and gain some positive diff stat.
