Re: MCP2515 DTS support

You are right Alexander!
The CONFIG_COMMON_CLK hasn't enable!
But for all SOC AT91_SAM9x5 still uses old clock style (AT91_USE_OLD_CLK):

config SOC_AT91SAM9X5
         bool "AT91SAM9x5 family"
         select HAVE_AT91_DBGU0
         select HAVE_FB_ATMEL
         select SOC_AT91SAM9
         select AT91_USE_OLD_CLK
         select HAVE_AT91_UTMI
         select HAVE_AT91_SMD
         select HAVE_AT91_USB_CLK

and one of dependencies for COMMON_CLK_AT91 is don't be AT91_USE_OLD_CLK

config COMMON_CLK_AT91
         bool
        default AT91_PMC_UNIT && USE_OF && !AT91_USE_OLD_CLK
         select COMMON_CLK

config OLD_CLK_AT91
         bool
         default AT91_PMC_UNIT && AT91_USE_OLD_CLK




Now came my question: Can I use CONFIG_COMMON_CLK without my ARCH 
support? If not, how we will support devices that need CONFIG_COMMON_CLK?

Lucas
