driver model bring-up of omap timer on dra72, dra74, am335x and am437x-sk evm

To prepare timer driver to DM/DT conversion do not build the exiting timer driver when CONFIG_TIMER is defined. But since omap's SPL doesn't support DM yet so built timer driver only for SPL build when CONFIG_TIMER is defined.

Adding timer_init function to create and initialize the timer device on platforms where u-boot,dm-pre-reloc is not used. Since there will be multiple timer devices in the system, adding a tick-timer node in chosen node to know which timer device to be used as tick timer in u-boot.

This changes now require every device tree provide a "tick-timer" under /chosen, which break all the existing dm timer enabled boards, and is not necessary.

We should do:

    if (node < 0) {
        ret = uclass_first_device(UCLASS_TIMER, &dev);
        if (ret)

nits: no need to declare another ret. Just "ret = device_probe(dev)".

Hmmm, yep not needed.

What about my comments in v2, that make timer_init() static or just move codes in timer_init() into this dm_timer_init()?

Oops, missed :)

The timer_init() code can be moved to dm_timer_init(), but since it provides timer uclass functionality I kept the code in timer-uclass driver.

Now since dm_timer_init() doesn't have any thing other than calling timer_init, I will move the dm_timer_init() to timer_uclass and move timer_init code to it.

Adding timer init function in timer-uclass driver to create and initialize the timer device on platforms where u-boot,dm-pre-reloc is not used. Since there will be multiple timer devices in the system, adding a tick-timer node in chosen node to know which timer device to be used as tick timer in u-boot.

Please drop this patch, will send a fixup patch as the series is already applied to u-boot-dm tree.

You can send a new patch if you like and I can replace it. Either works for me.

Just sent a follow-up patch. Its good to not change the pushed history.

Like SPI and I2C, timer devices also have multiple chip instances. This patch adds the flag 'DM_UC_FLAG_SEQ_ALIAS' in timer_uclass driver to control device sequence numbering.
