* Rename struct device_d to deviceSascha Hauer2023-01-101-6/+10
| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox. Over time it became clear that this won't happen, instead barebox struct device_d is basically the same as Linux struct device. Rename the struct name accordingly to make porting Linux code easier.

* clk: fixed-factor: add clk_hw registration functionsAhmad Fatoum2022-02-011-0/+9
| | | | | | | | | | Save users the hassle of opencoding by providing wrappers with the same Linux semantics: names are duplicated, same arguments and struct clk_hw is returned.

* clk: Add Linux functions to register a fixed factor clockSascha Hauer2021-06-071-0/+7
| | | | | | | | | Linux has clk_register_fixed_factor(). Add the same function with the same prototype for barebox to ease code porting from Linux.

| | | | | | | | | In Linux struct clk_fixed_factor is known to clk implementors. Do the same in barebox. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Link: https://lore.barebox.org/20210602095507.24609-11-s.hauer@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clk: introduce struct clk_hwSascha Hauer2021-06-071-14/+21
| | | | | | | | | | | | | | | | | | | In Linux the ops in struct clk_ops take a struct clk_hw * argument instead of a struct clk * argument as in barebox. With this taking new clk drivers from Linux requires a lot of mechanical conversions. Instead of doing this over and over again swallow the pill once and convert the existing barebox code over to clk_hw. The implementation is a little different from Linux. In Linux struct clk is only known to the core clock code. In barebox struct clk is publically known and it is embedded into struct clk_hw. This allows us to still use struct clk members in the clock drivers which we currently still need, because otherwise this patch would be even bigger.

* clk: rename clk_register() to bclk_register()Sascha Hauer2021-06-071-1/+1
| | | | | | | | | | | | Linux has a clk_register() function with a different semantics than barebox. Rename this function to bclk_register() so that we later can introduce a clk_register() function with the same semantics as Linux.

* clk: initial common clk supportSascha Hauer2012-10-041-0/+63
This adds barebox common clk support loosely based on the Kernel common clk support. differences are: - barebox does not need prepare/unprepare - no parent rate propagation for set_rate - struct clk is not really encapsulated from the drivers Along with the clk support we have support for some basic clk building blocks: - clk-fixed - clk-fixed-factor - clk-mux - clk-divider clk-fixed and clk-fixed-factor are completely generic, clk-mux and clk-divider are currently the way i.MX muxes/dividers are implemented.
