Both at91 and avr32 defines its own platform data structure for the macb driver and both share common structures though at91 includes a currently unused phy_irq_pin. Create a common macb_platform_data for macb that both at91 and avr32 can use. In future we can use this to support other architectures that use the same IP block with the macb driver. v2: rename eth_platform_data to macb_platform_data and allow at91_ether to share the platform data with macb.

2011-11-15PM / shmobile: Avoid restoring the INTCS state during initializationRafael J. Wysocki1-4/+8
The SH7372 PM domain initialization routine calls pd_power_up() that executes the domain's .resume() callback, if present, and for the A4R domain this callback attepmts to restore the INTCS state from uninitialized data. To avoid that, introduce __pd_power_up() that will only execute the domain's .resume() callback if its second argument is 'true' and make the SH7372 PM domain initialization use it with 'false' as its second argument. Redefine pd_power_up() as a wrapper around __pd_power_up(). Reported-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Tracked-down-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J.

2011-11-12ARM: 7160/1: setup: avoid overflowing {elf,arch}_name from proc_info_listWill Deacon1-2/+4
setup_processor copies the arch_name and elf_name fields out of the selected proc_info_list into two fixed size buffers. Since the proc_info_list structure is defined in a proc_*.S assembly file, this can lead to subtle errors if the strings defined there are too long (for example, corrupting the machine ID).

The following commits break cpuidle on SH-Mobile ARM: 46bcfad cpuidle: Single/Global registration of idle states e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state This patch remedies these issues by up-porting the SH-Mobile code to fit with the above introduced framework changes. It is worth noting that the new code becomes significantly cleaner, so these framework changes are very welcome. At the same time this breakage could probably have been avoided by grepping for "last_state" and "cpuidle_register_driver".

2011-11-11drivers: sh: Generalize runtime PM platform stub.Paul Mundt2-68/+1
The runtime PM platform support stub in use by ARM-based SH/R-Mobile platforms contains nothing that's specifically ARM-related and instead of wholly generic to anything using the clock framework. The recent runtime PM changes interact rather badly with the lazy disabling of clocks late in the boot process through the clock framework, leading to situations where the runtime suspend/resume paths are entered without a clock being actively driven due to having been lazily gated off. In order to correct this we can trivially tie in the aforementioned stub as a general fallback for all SH platforms that don't presently have their own runtime PM implementations (the corner case being SH-based SH-Mobile platforms, which have their own stub through the hwblk API -- which in turn has bitrotted and will be subsequently adapted to use the same stub as everyone else), regardless of whether the platforms choose to define power domains of their own or not. This fixes up regressions for clock framework users who also build in runtime PM support without any specific power domains of their own, which was previously causing the serial console to be lost when warring with lazy clock disabling.
