this addresses the clock driver aka provider's side of clocks - introduce a 'clocks' subtree with an 'osc' node for the crystal or oscillator SoC input (fixed frequency) - the 'clock@f00' clock-control-module node references the 'osc' for its input, and is another provider for all the clocks which the CCM component manages - prepare for future references to clocks from peripheral nodes by means of the <&clks ID> syntax and symbolic ID names which a header file provides - provide default values with 33MHz oscillator frequency in the common include (the 66MHz IPS bus already was there), and add override values for the ifm AC14xx board which deviates from the reference design (25MHz xtal, 80MHz IPS bus) Cc: Rob Herring <rob.herring@calxeda.com> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Stephen Warren <swarren@wwwdotorg.org> Cc: Ian Campbell <ian.campbell@citrix.com> Cc: linux-arm-kernel@lists.infradead.org Cc: devicetree@vger.kernel.org Reviewed-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>
