There's a few limitations on the original one cell clock binding (#clock-cells = <1>) that we have to define some SW clock IDs for device tree to reference. This may cause troubles if we want to use common clock IDs for multi platforms support when the clock of those platforms are mostly the same. e.g. Current clock IDs name are defined with SS prefix. However the device may reside in different SS across CPUs, that means the SS prefix may not valid anymore for a new SoC. Furthermore, the device availability of those clocks may also vary a bit. For such situation, we want to eliminate the using of SW Clock IDs and change to use a more close to HW one instead. For SCU clocks usage, only two params required: Resource id + Clock Type. Both parameters are platform independent. So we could use two cells binding to pass those parameters, Cc: Rob Herring <robh+dt@kernel.org> Cc: Stephen Boyd <sboyd@kernel.org> Cc: Shawn Guo <shawnguo@kernel.org> Cc: Sascha Hauer <kernel@pengutronix.de> Cc: Michael Turquette <mturquette@baylibre.com> Cc: devicetree@vger.kernel.org Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com>
