clk: ti: change ti_clk_register[_omap_hw]() API

2022-11-23T01:01:47Z

The ti_clk_register() and ti_clk_register_omap_hw() functions are always called with the parameter of type "struct device" set to NULL, since the functions from which they are called always have a parameter of type "struct device_node". Replacing "struct device" type parameter with "struct device_node" will allow you to register a TI clock to the common clock framework by taking advantage of the facilities provided by the "struct device_node" type. Further, adding the "of_" prefix to the name of these functions explicitly binds them to the "struct device_node" type. The patch has been tested on a Beaglebone board.

clk: ti: add am33xx/am43xx spread spectrum clock support

2021-06-09T00:49:16Z

The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs. As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for DDR, PER, and CORE PLLs. Calculating the required values and setting the registers accordingly was taken from the set_mpu_spreadspectrum routine contained in the arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project. In locked condition, DPLL output clock = CLKINP *[M/N]. In case of SSC enabled, the reference manual explains that there is a restriction of range of M values. Since the omap2_dpll_round_rate routine attempts to select the minimum possible N, the value of M obtained is not guaranteed to be within the range required. With the new "ti,min-div" parameter it is possible to increase N and consequently M to satisfy the constraint imposed by SSC.

clk/ti: Use kmemdup rather than duplicating its implementation

2019-09-06T21:20:15Z

kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

clk: ti: Don't reference clk_init_data after registration

2019-08-16T17:22:46Z

A future patch is going to change semantics of clk_register() so that clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid referencing this member here so that we don't run into NULL pointer exceptions.

clk: ti: generalize the init sequence of clk_hw_omap clocks

2019-02-15T14:46:22Z

Add a generic API for initializing clocks of clk_hw_omap type clocks, and convert the whole TI clock driver suite to use this for registering the clocks. Also, get rid of the now redundant API for adding the clocks to the OMAP HW clocks list; instead this is used directly from the register API.

clk: Use of_node_name_eq for node name comparisons

2018-12-14T21:52:41Z

Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer. For instances using of_node_cmp, this has the side effect of now using case sensitive comparisons. This should not matter for any FDT based system which all of these are.
