Message-Id: <1370281990-15090-1-git-send-email-mturquette@linaro.org> Date: Mon, 3 Jun 2013 10:53:07 -0700 From: Mike Turquette <mturquette@...aro.org> To: linux-kernel@...r.kernel.org Cc: linux-arm-kernel@...ts.infradead.org, devicetree-discuss@...ts.ozlabs.org, Mike Turquette <mturquette@...aro.org> Subject: [PATCH RFC 0/3] clk: dt: bindings for mux & divider clocks This series introduces binding definitions for common register-mapped clock multiplexor and divider IP blocks, and the corresponding setup functions once they are matched. The bindings are close the struct definitions but please don't hold that against the binding: the struct definitions closely model the hardware. The only missing basic clock type is the gate clock. A binding for that was posted some time back and is similar in spirit to these[1]. I guess we'll need to decide whether register-level programming details belong in DT. I believe they do since those details describe the hardware. Note that there is still no generic clock driver that matches these basic types, but it would be trivial to write one. Thoughts on that? Is it better for each of the basic clock types to be a driver that matches, or should there be one drivers/clk/clk-basic.c which matches all of the basic clock building blocks? I like the latter for aesthetic purposes. I am using this code while converting the OMAP4 clock data over to DT and some common boilerplate code can be factored out of several clock drivers if this is merged.
