Looks like this adds some duplicate #include "clock.h",
we already have it in many places, so plat/clock.h changes
can be just dropped.
I've applied your patches locally with the other plat
header cleanup and fixed up the issue keeping the existing
clock.h. Updated patch below for what I have, probably
won't apply to your branch without conflicts right now.
But you can see where the duplicates are with:
$ grep -rc 'include "clock.h"' arch/arm/*omap*/* | grep ":2"
Anyways, let's wait few days before we do some immutable
branch as we still have the late patches missing from
the mainline kernel.
Regards,
Tony

Subject: [PATCH] ARM: OMAP: remove plat/clock.h
Remove arch/arm/plat-omap/include/plat/clock.h by merging it into
arch/arm/mach-omap1/clock.h and arch/arm/mach-omap2/clock.h.
The goal here is to facilitate ARM single image kernels by removing
includes via the "plat/" symlink.

-/**
- * struct clk - OMAP struct clk
- * @node: list_head connecting this clock into the full clock list
- * @ops: struct clkops * for this clock
- * @name: the name of the clock in the hardware (used in hwmod data and debug)
- * @parent: pointer to this clock's parent struct clk
- * @children: list_head connecting to the child clks' @sibling list_heads
- * @sibling: list_head connecting this clk to its parent clk's @children
- * @rate: current clock rate
- * @enable_reg: register to write to enable the clock (see @enable_bit)
- * @recalc: fn ptr that returns the clock's current rate
- * @set_rate: fn ptr that can change the clock's current rate
- * @round_rate: fn ptr that can round the clock's current rate
- * @init: fn ptr to do clock-specific initialization
- * @enable_bit: bitshift to write to enable/disable the clock (see @enable_reg)
- * @usecount: number of users that have requested this clock to be enabled
- * @fixed_div: when > 0, this clock's rate is its parent's rate / @fixed_div
- * @flags: see "struct clk.flags possibilities" above
- * @clksel_reg: for clksel clks, register va containing src/divisor select
- * @clksel_mask: bitmask in @clksel_reg for the src/divisor selector
- * @clksel: for clksel clks, pointer to struct clksel for this clock
- * @dpll_data: for DPLLs, pointer to struct dpll_data for this clock
- * @clkdm_name: clockdomain name that this clock is contained in
- * @clkdm: pointer to struct clockdomain, resolved from @clkdm_name at runtime
- * @rate_offset: bitshift for rate selection bitfield (OMAP1 only)
- * @src_offset: bitshift for source selection bitfield (OMAP1 only)
- *
- * XXX @rate_offset, @src_offset should probably be removed and OMAP1
- * clock code converted to use clksel.
- *
- * XXX @usecount is poorly named. It should be "enable_count" or
- * something similar. "users" in the description refers to kernel
- * code (core code or drivers) that have called clk_enable() and not
- * yet called clk_disable(); the usecount of parent clocks is also
- * incremented by the clock code when clk_enable() is called on child
- * clocks and decremented by the clock code when clk_disable() is
- * called on child clocks.
- *
- * XXX @clkdm, @usecount, @children, @sibling should be marked for
- * internal use only.
- *
- * @children and @sibling are used to optimize parent-to-child clock
- * tree traversals. (child-to-parent traversals use @parent.)
- *
- * XXX The notion of the clock's current rate probably needs to be
- * separated from the clock's target rate.
