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:

As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.

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: -

The DEBUG_AT91_UART Kconfig option was forgotten when moving the AT91 debug-macro.S file. Add it and use it for the at91.S compilation. Reported-by:

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. Signed-off-by:

According to v4l2 dt document, we add: a camera host: ISI port. a i2c camera sensor: ov2640 port. to sama5d3xmb.dtsi. The ov2640 node defines the pinctrls, clocks and refer to isi port. The ISI node also has a reference to the ov2640 port. Signed-off-by:

For sama5d3xmb board, the pins: pinctrl_isi_pck_as_mck is pck1, and used to provide MCK for camera sensor. We change its name to: pinctrl_pck1_as_isi_mck. As we want camera sensor instead of ISI to configure the pck1 (ISI_MCK) pin. So we remove this pinctrl from ISI DT node. It will be added in sensor's DT node. Signed-off-by:

For sama5d3xmb board, the pins: pinctrl_isi_{power,reset} is used to power-down or reset camera sensor. So we should let camera sensor instead of ISI to configure the pins. This patch will change pinctrl name from pinctrl_isi_{power,reset} to pinctrl_sensor_{power,reset}. And remove these two pinctrl from ISI's DT node. We will add these two pinctrl to sensor's DT node.
