Remove the string "(Device Tree)" after the machine name because all AT91 machines use the DT nowadays. Also change some function names to unify following the convention: - at91sam9xxx aren't named sam9, 9xxx but with the full name - sama5 are the ones that don't have the at91 prefix anymore.

Move the ramc initialization to pm.c as it is the only user left. This allows us to get rid of at91_dt_initialize() that was the only one called by the init_early() function pointer of struct machine_desc.

The PM initialization needs internal SRAM for allocating a gen_pool and use it to store its PM code. So we need to have of_platform_populate() before this code. Suggested-by: NAlexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: NNicolas Ferre <nicolas.ferre@atmel.com>

Newer SoCs: at91sam9x5, at91sam9n12, sama5d3 and sama5d4 embed a DDR controller and have a different PMC status register layout than the at91sam9g45. Create another at91_sam9x5_pm_init() function to match this compatibility. Signed-off-by: NNicolas Ferre <nicolas.ferre@atmel.com>

Split at91_pm_init() in three variants that are called by the respective SoCs .init_machine. This allows to remove the of_machine_is_compatible() calls and move at91_pm_init() out of arch_initcall() which is required for multiplatform.

Appearance: On some SAMA5D4EK boards, after power up, the Eth1 doesn't work. Reason: The PIOE2 pin is connected to the NAND_Tree# of KSZ8081, But it outputs LOW during the reset period, which cause the NAND_Tree# enabled. Add phy_fixup() to disable NAND_Tree by overriding the Operation Mode Strap Override register(i.e. Register 16h) to clear the NAND_Tree bit.

SoC identification code, kernel uncompress and low level debugging routines update. On SAMA5D4, DBGU is at another address AT91_BASE_DBGU2 so another round of detection is needed. We also had to differentiate with SAMA5D3 SoC family and rename some variables.

The PIT timer driver until now had a single probe function, disregarding wether it was probed through DT or in the old-style way. This code later on was calling some DT function to retrieve the proper values for its base address, interrupts and clocks. While this was working, it was preventing the usage of CLOCKSOURCE_OF_DECLARE, and the two different probe path were not as clearly separated as they could be. Rework the probe path to take this into account, and switch to CLOCKSOURCE_OF_DECLARE.

Remove selection of OLD_IRQ_AT91 when selecting dt boards. Select ATMEL_AIC_IRQ for sama5 SoCs (a kernel compiled for this SoC will always use ATMEL_AIC_IRQ driver). Select ATMEL_AIC_IRQ for at91rm9200 and at91sam9 SoCs only if OLD_IRQ_AT91 is not selected (which means we are compiling a pure DT kernel, without any legacy board support). Remove specific irq init code in all dt board files: this init procedure is automatically handled in of_irq_init which is called by the arm irq core code and is in charge of calling the appropriate aic init functions.

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.
