2014-05-12ARM: shmobile: Use r8a7791 DT CPU Frequency for KoelschMagnus Damm
Convert the Koelsch board support to use shmobile_init_delay() to be able to migrate away from per-SoC delay setup functions. Signed-off-by: Magnus Damm <damm+renesas@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2014-02-18ARM: shmobile: Remove Koelsch DT reference legacy clock bitsMagnus Damm
Koelsch DT reference is these days built for multiplatform only which means that CCF comes with the package. Remove unused legacy code ifdefs to clean up the code.

2014-02-17ARM: shmobile: koelsch-reference: Add DU deviceLaurent Pinchart
The DU device has no DT bindings yet, instantiate it as a platform device for now. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Acked-by: Magnus Damm <damm@opensource.se> [horms+renesas@verge.net.au: omitted DTS portion] Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2014-02-17ARM: shmobile: koelsch-reference: Refactor clock lookup hackLaurent Pinchart
Make the clock lookup hack more generic to ease the addition of more devices. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2014-02-04ARM: shmobile: koelsch: fix error return code check from clk_get()Ben Dooks
The koelsch_add_standard_devices() function calls clk_get() but then fails to check that it returns an error pointer instead of NULL on failure. This was added by f31239ef ("ARM: shmobile: koelsch-reference: Instantiate clkdevs for SCIF and CMT") in Simon Horman's renesas-boards2-for-v3.14 tag. The issue is not serious as it does not cause a crash and seems to not be actually causing any issues now the other clock bugs have been fixed.

2013-12-19ARM: shmobile: Let Koelsch multiplatform boot with Koelsch DTBLaurent Pinchart
Let the multiplatform Koelsch support boot with the legacy DTS for Koelsch as well as the Koelsch reference DTS. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-12-19ARM: shmobile: koelsch-reference: Instantiate clkdevs for SCIF and CMTLaurent Pinchart
Now that the common clock framework is supported, the clock lookup entries in clock-r8a7791.c are not registered anymore. Devices must instead reference their clocks in the device tree. However, SCIF and CMT devices are still instantiated through platform code, and thus need a clock lookup entry. Retrieve the SCIF and CMT clock entries by name and register clkdevs for the corresponding devices. This will be removed when the SCIF and CMT devices will be instantiated from the device tree.

2013-12-19ARM: shmobile: koelsch-reference: Remove duplicate CCF initializationLaurent Pinchart
The common clock framework is initialized in the rcar_gen2_init_timer() function, remove the of_clk_init() call. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-12-10ARM: shmobile: Use ->init_late() on KoelschMagnus Damm
Hook in shmobile_init_late() on Koelsch. This enables some PM related things like CPUIdle and Suspend-to-RAM. With this patch applied it is possible to use Suspend-to-RAM: # echo enabled > /sys/class/tty/ttySC6/power/wakeup # echo mem > /sys/power/state (wake by sending a character on the serial console) Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-12-10ARM: shmobile: Initial r8a7791 and Koelsch multiplatform supportMagnus Damm
Add Koelsch and r8a7791 to CONFIG_SHMOBILE_MULTI. At this point CCF is not yet supported so you cannot run this code yet. For CCF support to happen several different components are needed, and this is one simple portion that moves us forward. Other patches need to build on top of this one. Koelsch board support exists in 3 flavors: 1) SHMOBILE_MULTI, MACH_KOELSCH - board-koelsch-reference.c (CCF + DT) 2) SHMOBILE, MACH_KOELSCH_REFERENCE - board-koelsch-reference.c (DT) 3) SHMOBILE, MACH_KOELSCH - board-koelsch.c (legacy C code) When CCF is done then 2) will be removed. When 1) includes same features as 3) then 3) will be removed. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-12-10ARM: shmobile: r8a7791 Koelsch DT reference C bitsMagnus Damm
Add DT reference support for the r8a7791 Koelsch board. This board support file will be used together with common clocks and multiplatform in the future. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
