clk: mxs: Include clk.h in C files that use it Clock provider drivers generally shouldn't include clk.h because it's the consumer API. The clk.h include is being included in all mxs files because it's part of mxs/clk.h even though nothing actually requires it in that file. Move the clk.h include to the C files that are actually using it and remove the clk.h include from the header file. The clkdev.h include isn't used either, so drop it too.

clk: don't use __initconst for non-const arrays The statement static const char *name[]; defines a modifiable array of pointers to constant chars. That is *name[0] = 'f'; is forbidden, but name[0] = "f"; is not. So marking an array that is defined as above with __initconst is wrong. Either an additional const must be added such that the whole definition reads: static const char *const name[] __initconst; or where this is not possible __initdata must be used.

clk: mxs: Fix invalid 32-bit access to frac registers According to i.MX23 and i.MX28 reference manual [1],[2] the fractional clock control register is 32-bit wide, but is separated in 4 parts. So write instructions must not apply to more than 1 part at once. The clk init for the i.MX28 violates this restriction and all the other accesses on that register suggest that there isn't such a restriction. This patch restricts the access to this register to byte instructions and extends the comment in the init functions. Btw the imx23 init now uses a R-M-W sequence just like imx28 init to avoid any clock glitches. The changes has been tested with a i.MX23 and a i.MX28 board.

clk: mxs: replace imx23 clk_register_clkdev with clock DT lookup It really becomes a maintenance issue that every time a device needs to look up (clk_get) a clock we have to patch kernel clock file to call clk_register_clkdev for that clock. Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx23 client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.
