| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove SoC dependency and make it generic for every Atmel ARM AT91. That will allow to select this driver for newer chips. Keep dependency on AT91 because of the use of an header file located in include/mach directory. Modify the comment to reflect this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we are using irqdomains, we need to convert GPIO pins to Linux IRQ numbers using the gpio_to_irq() function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since SDIO drivers may want to do some SDIO operations in their suspend callback functions, we must not keep the host claimed when calling them.
