2012-05-08clk: prevent spurious parent rate propagationMike Turquette
Patch 'clk: always pass parent_rate into .round_rate' made a subtle change to the semantics of .round_rate. It is now expected for the parent's rate to always be passed in, simplifying the implemenation of various .round_rate callback definitions. However the patch also introduced a bug in clk_calc_new_rates whereby a clock without the CLK_SET_RATE_PARENT flag set could still propagate a rate change up to a parent clock if the the .round_rate callback modified the &best_parent_rate value in any way. This patch fixes the issue at the framework level (in clk_calc_new_rates) by specifically handling the case where the CLK_SET_RATE_PARENT flag is not set.

2012-05-01clk: Use a separate struct for holding init data.Saravana Kannan
Create a struct clk_init_data to hold all data that needs to be passed from the platfrom specific driver to the common clock framework during clock registration. Add a pointer to this struct inside clk_hw. This has several advantages: * Completely hides struct clk from many clock platform drivers and static clock initialization code that don't care for static initialization of the struct clks. * For platforms that want to do complete static initialization, it removed the need to directly mess with the struct clk's fields while still allowing to statically allocate struct clk. This keeps the code more future proof even if they include clk-private.h. * Simplifies the generic clk_register() function and allows adding optional fields in the future without modifying the function signature. * Simplifies the static initialization of clocks on all platforms by removing the need for forward delcarations or convoluted macros.

2012-04-26pinctrl: enhance reporting of errors when loading from DTJohn Crispin
There are a few places in the api where the code simply returns -EINVAL when it finds an error. An example is pinmux_map_to_setting() which now reports an error if we try to match a group with a function that it does not support. The reporting of errors in pinconf_check_ops and pinmux_check_ops now has the same style and is located inside the according functions and not the calling code. When the map is found in the DT but the default state can not be selected we get an error to know that the code at least tried. The patch also removes a stray word from one comment and a "->" from another for the sake of consistency. Finally we replace a few pr_err/debug() calls with dev_err/dbg(). Thanks go to Stephen Warren for reviewing the patch and enhancing the reporting inside pinmux_map_to_setting().
