The header file is currently under plat-omap directory under arch/omap. Move this out to an accessible place.

No Code changes done to the header file.

Some of the dmtimer functions are in this header to optimize the size of the system timer code. Can you please check if some of them can be left out of dmtimer.h and be made private to mach-omap1/timer.c and mach-omap2/timer.c?

Again, we don't want driver code to start mis-using these as that's immediately going to be big mess out of control.

Regards,

Tony

Tony,

Only function that i could push out of dmtimer.h was __omap_dm_timer_override_errata

which is being currently called by mach-omap2/timer.c alone.

Rest all are used both my dmtimer.c as well as mach-omap2/timer.c. Here is the list:

__omap_dm_timer_read
__omap_dm_timer_write
__omap_dm_timer_init_regs
__omap_dm_timer_enable_posted
__omap_dm_timer_stop
__omap_dm_timer_load_start
__omap_dm_timer_int_enable
__omap_dm_timer_read_counter
__omap_dm_timer_write_status

Any preferences on moving them to dmtimer.c or leaving them in header file?

The header file is currently under plat-omap directory under arch/omap. Move this out to an accessible place.

No Code changes done to the header file.

Move the dmtimer driver out of plat-omap to clocksource. So that non-omap devices also could use this.

No Code changes done to the driver file.

The series moves dmtimer out of plat-omap to drivers/clocksource. The series also does a bunch of changes to pwm-omap-dmtimer code to adapt to the driver migration and clean up plat specific pdata-quirks and use the dmtimer platform data.

Boot tested on DRA7-EVM and AM437X-GP-EVM.

More testing would be of great help.

Btw, what are these pathes against. Here's how it ends against 4.14-rc8:
Applying: clocksource: dmtimer: Remove all the exports
Applying: arm: omap: Move dmtimer.h out of plat-omap
Applying: arm: OMAP: Move dmtimer driver out of plat-omap to drivers under clocksource
error: patch failed: drivers/clocksource/Kconfig:46
error: drivers/clocksource/Kconfig: patch does not apply
Patch failed at 0003 arm: OMAP: Move dmtimer driver out of plat-omap to drivers under clocksource

Test above was using your first serie which I manually fixed to apply. Given the fact there is no code change, I will not do this again :-) (and I'm happy someone is cleaning dm timer code, thank you)

The series moves dmtimer out of plat-omap to drivers/clocksource. The series also does a bunch of changes to pwm-omap-dmtimer code to adapt to the driver migration and clean up plat specific pdata-quirks and use the dmtimer platform data.

Boot tested on DRA7-EVM and AM437X-GP-EVM.

Boot tested on IGEPv2 with DM3730 and OMAP3530

Thanks for Testing :-).

More testing would be of great help.

No code changes in this v2 version. Only enhanced patch statistics for renames.

Btw, what are these pathes against. Here's how it ends against 4.14-rc8:
Applying: clocksource: dmtimer: Remove all the exports
Applying: arm: omap: Move dmtimer.h out of plat-omap
Applying: arm: OMAP: Move dmtimer driver out of plat-omap to drivers under clocksource
error: patch failed: drivers/clocksource/Kconfig:46
error: drivers/clocksource/Kconfig: patch does not apply
Patch failed at 0003 arm: OMAP: Move dmtimer driver out of plat-omap to drivers under clocksource

Test above was using your first serie which I manually fixed to apply. Given the fact there is no code change, I will not do this again :-) (and I'm happy someone is cleaning dm timer code, thank you)

I had rebased to latest next branch. Not sure what went wrong there. Let me check myself.

I will rebase with all other comments fixed to the next branch and post v3.

Thanks Ladis.
