* ARM: at91: merge all SOC_AT91SAM9xxxAlexandre Belloni2015-02-021-19/+0
| | | | | | | | | | | | | | | | Only use SOC_AT91SAM9 for all the at91sam9 SoCs. It removes all the empty at91sam9xxx.c SoC files. It also removes the useless at91_init_soc affectation procedure and its "init" function pointer. Only the SoC detection and display are kept for the at91sam9: at91_soc_is_enabled() and at91_boot_soc.map_io() function calls are also removed. It enables HAVE_AT91_SMD and HAVE_AT91_UTMI for all the sam9 SoCs but this only represents 96 bytes of uncompressed kernel code.

This options is also selected when the user choose non dt boards support (new at91 clks can only be registered from a device tree definition). - COMMON_CLK_AT91: this option cannot be selected directly. Instead it is enabled if these 3 conditions are met: * at least one of the selected SoCs have a PMC (Power Management Controller) Unit * device tree support is enabled * the old at91 clk implementation is disabled (every selected SoC define its clks in its device tree and non dt boards support is disabled) - OLD_CLK_AT91: this option cannot be selected directly. Instead it is enabled if these 2 conditions are met: * at least one of the selected SoCs have a PMC (Power Management Controller) Unit * at least one of the selected SoCs does not define its clks in its device tree or non dt-boards support is enabled This patch selects AT91_USE_OLD_CLK in all currently supported SoCs. These selects will be removed after clk definitions are properly added in each soc's device tree. It also selects AT91_USE_OLD_CLK in all non-dt boards support. AT91_PMC_UNIT references are replaced by OLD_CLK_AT91, because PMC Unit is enabled for both old and common clk implementations, and old clk implementation should not be compiled if COMMON_CLK is enabled. To avoid future link errors, a new stub is created for at91_dt_clock_init function if OLD_CLK_AT91 is disabled. A new check is added in dt init functions (setup.c) to prepare for SoCs supporting new clk implementation. These SoCs won't setup the register_clocks callback (clk registration is done using of_clk_init).

| | | | | | | | | | | | | | | | | Since 4b68520dc0ec96153bc0d87bca5ffba508edfcf ARM: at91: add AIC5 support we allocate the at91_extern_irq. This patch makes it static and stores the non-dt extern irq in the soc structure. It is then possible to use a at91_get_extern_irq() function to get the value for outside of the irq driver. It is useful for passing its value to at91_aic_init().
