[PATCH v8 0/3] PIC32MZDA Clock Driver

[Joshua Henderson]

Clock bindings got acked and then essentially unacked, while the clock
driver never made it upstream. In the meantime, the initial DTS file
made it upstream. This latest patch series includes a patch to go back
and correct the DTS files to reflect the new clock bindings in this
patch series.

This series still uses the CLK_OF_DECLARE approach despite not being
regarded as the best approach. On MIPS/PIC32 the first call of clk_get()
happens from "start_kernel -> time_init() -> plat_time_init()" which is
very early in boot sequence even before execution of early_initcall().
In short, by platform_driver way I was not able to register clock(s)
before the first clock user becomes ready. With CLK_OF_DECLARE() I can
explicitly call of_clk_init() in plat_time_init() just before calling
clk_get().
