Hello,
This patch series was formerly part of the
"ARM: at91: move to common clk framework" patch series.
It moves sama5d3 SoCs and boards to the new at91 clks (clk implementation
using common clk framework).
This patch series depends on following patch series (they must be applied in
this order):
1) "ARM: at91/dt: split sama5d3 definition" (v1)
2) "ARM: at91/dt: make use of periph id macros" (v2, not submitted yet)
3) "ARM: at91: move to common clk framework" (v3)
I will answer to this mail and join this patch series' dependencies in
attachments.
Best Regards,
Boris

Clocks registration cannot be done in early init callback (as formerly done by the old clk implementation) because it requires dynamic allocation which is not ready yet during early init. In the other hand, at91 clocks must be registered before at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver request the master clk (mck). A new function (at91sama5_dt_timer_init) is created to fullfil these needs. This function registers all at91 clks using the dt definition before calling the PIT init function. The device tree clock registration is enabled only if common clk is selected. Else the old clk registration is been done during at91_dt_initialize call.

* [PATCH 1/6] ARM: at91: prepare sama5 dt boards transition to common clk @ 2013-08-08 8:46 Boris BREZILLON 0 siblings, 0 replies; 15+ messages in thread From: Boris BREZILLON @ 2013-08-08 8:46 UTC (permalink / raw) To: linux-arm-kernel This patch prepare the transition to common clk for sama5 dt boards by replacing the timer init callback. Clocks registration cannot be done in early init callback (as formerly done by the old clk implementation) because it requires dynamic allocation which is not ready yet during early init. In the other hand, at91 clocks must be registered before at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver request the master clk (mck). A new function (at91sama5_dt_timer_init) is created to fullfil these needs. This function registers all at91 clks using the dt definition before calling the PIT init function. The device tree clock registration is enabled only if common clk is selected. Else the old clk registration is been done during at91_dt_initialize call.
