if (!clk->ops->round_rate && (clk->flags & CLK_SET_RATE_PARENT)) is true, then we don't need to set clk->new_rate here, as we will call clk_calc_subtree() afterwards and it also sets clk->new_rate.

This patch tries to remove duplicate code for clk_gate clocks. This creates another routine clk_gate_endisable() which will take care of enable/disable clock with knowledge of CLK_GATE_SET_TO_DISABLE flag. It works on following logic: For enabling clock, enable = 1 set2dis = 1 -> clear bit -> set = 0 set2dis = 0 -> set bit -> set = 1 For disabling clock, enable = 0 set2dis = 1 -> set bit -> set = 1 set2dis = 0 -> clear bit -> set = 0 So, result is always: enable xor set2dis.

Need to propagate round_rate call for the clk that has no .round_rate operation but with flag CLK_SET_RATE_PARENT set. For example, clk_mux is a clk with no .round_rate operation. However, it could likely be in a clk_set_rate propagation path, saying it has parent clk who has .round_rate and .set_rate operations.

This patch is the basic clk version of 'clk: core: copy parent_names & return error codes'. The registration functions are changed to allow the core code to copy the array of strings and allow platforms to declare those arrays as __initdata. This patch also converts all of the basic clk registration functions to return error codes which better aligns them with the existing clk.h api. Signed-off-by: NMike Turquette <mturquette@linaro.org>

This patch cleans up clk_register and solves a few bugs by teaching clk_register and __clk_init to return error codes (instead of just NULL) to better align with the existing clk.h api. Along with that change this patch also introduces a new behavior whereby clk_register copies the parent_names array, thus allowing platforms to declare their parent_names arrays as __initdata.

Besides the static initialization, the clk_ops of basic clks could also be used by particular clk type being subclass of the basic clks. For example, clk_busy_divider has the same clk_ops as clk_divider, except it has to wait for a busy bit before return success with .set_rate. clk_busy_divider will somehow reuse clk_ops of clk_divider. Since clk-provider.h is included by clk-private.h, it's safe to move those clk_ops declaration of basic clks form clk-private.h into clk-provider.h, so that implementation of clks like clk_busy_divider above do not need to include clk-private.h to access those clk_ops.

Commit c79396c1 ("mmc: sdhci: prevent card detection activity for non-removable cards") disables card detection where the cards are marked as non-removable. This makes sense, but the implementation detail of calling mmc_card_is_removable() causes some problems, because mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root filesystem is stored on SD, but we also have external SD card slots where we want automatic card detection. Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE, which is defined to mean that the card is *really* nonremovable. This could be revisited in future if we find a way to improve CONFIG_MMC_UNSAFE_RESUME semantics.

This continues the theme started with vm_brk() and vm_munmap(): vm_mmap() does the same thing as do_mmap(), but additionally does the required VM locking. This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf.
