clk: at91: Add clock driver The patch is referred to at91 clock driver of Linux, to make the clock node descriptions in DT aligned with the Linux's. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Reviewed-by: Simon Glass <sjg@chromium.org> 2016-07-20 09:55:12 +00:00			`/*`

clk: at91: Improve the clock implementation For the peripheral clock, provide the clock ops for the clock provider, such as spi0_clk. The .of_xlate is to get the clk->id, the .enable is to enable the spi0 peripheral clock, the .get_rate is to get the clock frequency. The driver for periph32ck node is responsible for recursively binding its children as clk devices, not provide the clock ops. So do the generated clock and system clock.

clk: Modify xlate() method for livetree Update the xlate() method to use ofnode_phandle_args instead of the fdtdec variant. This will allow drivers to support a live device tree.
