Many platforms support simple gateable clocks, fixed-rate clocks, adjustable divider clocks and multi-parent multiplexer clocks.
This patch introduces basic clock types for the above-mentioned hardware which share some common characteristics.
Hi Mike
These basic clocks don't allow the use of prepare/unprepare, from the side of the clock provider. I think i need this.
The Orion Kirkwood SoC has clock gating for most of its on chip peripherals, which the other older Orion devices don't have. The SATA and PCIe also allows the PHY to be shut down, again which older Orion devices don't have. The current code links the clock and the PHY together, shutting both down are the same time. So i would like to perform the PHY shutdown in the unprepare() function of the clk driver.
Is allowing to pass prepare/unprepare functions to basic clocks something you want to support? If i prepare a patch would you consider it?
Thanks Andrew
