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. Signed-off-by:

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. Signed-off-by:

This finally gets dm816x into a usable shape for further work to happen after a few years of stalled effort of making this SoC to work with the mainline kernel.

Add minimal hwmod support that works at least on dm8168. This is based on the code in the earlier TI CDP tree, and an earlier patch by Aida Mynzhasova <aida.mynzhasova@skitlab.ru>. I've set up things to work pretty much the same way as for am33xx. We are basically using cm33xx.c with a different set of clocks and clockdomains. This code is based on the TI81XX-LINUX-PSP-04.04.00.02 patches published at: http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/TI81XX_04_04/04_04_00_02/index_FDS.html Cc: Aida Mynzhasova <aida.mynzhasova@skitlab.ru> Cc: Brian Hutchinson <b.hutchman@gmail.com> Acked-by:

This patch adds required definitions and structures for clockdomain initialization, so omap3xxx_clockdomains_init() was substituted by new ti81xx_clockdomains_init() while early initialization of TI81XX platform. Note that we now need to have 81xx in a separate CONFIG_SOC_TI81XX block instead inside the ifdef block for omap3 to avoid make randconfig build errors. This code is based on the TI81XX-LINUX-PSP-04.04.00.02 patches published at: http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/TI81XX_04_04/04_04_00_02/index_FDS.html Cc: Brian Hutchinson <b.hutchman@gmail.com> Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by:

As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt.
