Now that r8a7791 has CCF support remove the legacy Koelsch reference Kconfig bits CONFIG_MACH_KOELSCH_REFERENCE for the non-multiplatform case. Starting from this commit Koelsch board support is always enabled via CONFIG_MACH_KOELSCH, and CONFIG_ARCH_MULTIPLATFORM is used to select between board-koelsch.c and board-koelsch-reference.c The file board-koelsch-reference.c can no longer be used together with the legacy sh-clk clock framework, instead CCF is used.

2013-12-19ARM: shmobile: koelsch-reference: Instantiate clkdevs for SCIF and CMTLaurent Pinchart1-1/+29
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.

2013-12-14ARM: shmobile: Add select MIGHT_HAVE_PCI for PCI-AHB bridge codeBen Dooks1-0/+4
The PCI sub-system is not enabled by default on ARM and on certain Renesas devices the build does not select it. This means that there are configurations that do not allow the AHB-PCI bridge used for the USB sub-systems to be built. For the R8A7790, R8A7791 and EMEV-2 select MIGHT_HAVE_PCI to allow the PCI drivers to be built. Also select MIGHT_HAVE_PCI for the multi-config where there may be many Reneasas devices selected.

2013-12-10ARM: Kconfig: Mention Renesas ARM SoCs instead of SH-MobileLaurent Pinchart2-12/+13
Only the SH-Mobile product name is mentioned in the Kconfig descriptions and help texts. This makes it difficult for external engineers working on other Renesas platforms to find upstream platform support as the combination of the SH-Mobile name and using the product number proved an effective method of concealment.

2013-12-10ARM: shmobile: mackerel: clk_round_rate() can return a zero to indicate an errorPaul Walmsley1-2/+2
Treat both negative and zero return values from clk_round_rate() as errors. This is needed since subsequent patches will convert clk_round_rate()'s return value to be an unsigned type, rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz. Eventually, when calling clk_round_rate(), only a return value of zero will be considered a error. All other values will be considered valid rates. The comparison against values less than 0 is kept to preserve the correct behavior in the meantime.

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>
