Additionally, the 'init_time' callback of all machine descriptors for exynos platforms that were previously set to 'exynos4_timer_init' are now set to either 'mct_init' or 'clocksource_of_init'.

This also helps in adding device tree support for MCT controller driver by allowing the driver to retrieve interrupt numbers from device tree and populating them into this table, thereby supporting both legacy and dt functionality to co-exist.

With device tree support for MCT controller, it is possible to remove the static remap of the MCT controller address space and do the remap during the initialization of the MCT controller with the physical address obtained from the device tree. So in preparation of adding device tree support for MCT controller, add a new register base address variable that will hold the remapped MCT controller base address and convert all MCT register read/writes to use this new variable as the base address instead of the fixed S5P_VA_SYSTIMER. While at it, the MCT register offset and bit mask definitions are moved into the MCT controller driver file since there are no other consumers of these definitions.

This would get all the simple stuff out of the way, and I don't think there is a big risk of introducing regressions with these. A lot of the other patches have already been merged into subsystem trees. After this series in in arm-soc, what is left comes down to * The ASoC conversion to dmaengine won't make it unless someone who knows that code better steps up to do it right away. This means that we won't have audio in a 3.10 multiplatform kernel on Exynos, but it will still work for users that don't enable multiplatform. * The irqchip (combiner), clk and clksource patches are all based on top of other changesets we pulled in from your trees, so I would not make them part of the next/multiplatform branch. We can apply them on top of the next/drivers branch once they are tested successfully. * A trivial patch is needed in the end to actually make CONFIG_ARCH_EXYNOS visible in multiplatform configurations. We will do that as a separate patch once everything else is there. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The multiplatform variant has a number of limitations at the moment: * It only supports DT-enabled machines. This is not a problem in the long run, as non-DT machines for exynos are going away. The main problem here is that the gpio code and the exynos_eint irqchip are not multiplatform capable but still required for ATAGS based boot. * The watchdog driver is still missing a conversion. * sparsemem and memory_holes are currently not supported in multiplatform. The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled for now, as dependent patches are still pending in other subsystem trees. We will enable it once everything comes together.

Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.
