Hi Scott, Quoting Scott Wood (2015-06-18 19:49:10)
The existing device tree bindings are error-prone and inflexible. =
Correct the mistake by moving the knowledge into the driver, which has more flexibility in describing the quirks of each chip. This leaves the device tree to its proper role of identifying a programming interface rather than describing its individual registers.
Sorry for not responding to this one sooner. Fell through the cracks. All of the changes to drives/clk/clk-qoriq.c look great to me. I assume you need to keep all of these patches together and want to the take through the freescale tree? If so feel free to add, Acked-by: Michael Turquette <mturquette@baylibre.com> Regards, Mike
