| | | | | | | | | | | | | | | | | | | | | | | | The current CPU clock is missing the option to change the rate of its parents, leading to improper rates calculated by cpufreq, and eventually crashes.

* | clk: Convert to using %pOF instead of full_nameRob Herring2017-07-211-2/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

* clk: sunxi-ng: sun5i: Fix ahb_bist_clk definitionBoris Brezillon2017-05-251-1/+1
| | | | | | | | | | | | | | | | | | | | AHB BIST gate is actually controlled with bit 7. This bug was detected while trying to use the NAND controller which is using the DMA engine to transfer data to the NAND. Since the ahb_bist_clk gate bit conflicts with the ahb_dma_clk gate bit, the core was disabling the DMA engine clock as part of its 'disable unused clks' procedure, which was causing all DMA transfers to fail after this point.

The Allwinner A10s, A13, R8 and NextThing GR8 are all based on the same silicon, and all share the same clocks. However, they're not packaged in the same way, and therefore not all the controllers are actually available on all these SoCs. Introduce a clock controller driver for all these SoCs with different compatibles to take that into account.
