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

2023-11-20T10:06:47+00:00

[ Upstream commit 3400d546a741a2b2001d88e7fa29110d45a3930d ] 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: Update component clocks to use ti_dt_clk_name()

2023-11-20T10:06:47+00:00

[ Upstream commit ed06099c5d0b329082cc19c58eace0b20bf7fe70 ] Let's update all the TI component clocks to use ti_dt_clk_name() instead of devicetree node name if available.

clk: ti: generalize the init sequence of clk_hw_omap clocks

2019-02-15T14:46:22+00:00

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: Convert to using %pOFn instead of device_node.name

2018-08-30T16:50:20+00:00

In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier.

clk: ti: Drop legacy clk-3xxx-legacy code

We have now had omap3 booting in device tree only mode for a while and all this code is unused. Acked-by: Tero Kristo Signed-off-by: Tony Lindgren

clk: ti: convert to use proper register definition for all accesses

2017-03-08T11:06:15+00:00

Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage. Signed-off-by: Tero Kristo Acked-by: Tony Lindgren

clk: ti: fix ti_clk_get_reg_addr error handling

2015-03-24T18:23:36+00:00

There is a case where NULL can be a valid return value for ti_clk_get_reg_addr, specifically the case where both the provider index and register offsets are zero. In this case, the current error checking against a NULL pointer will fail. Thus, change the API to return a ERR_PTR value in an error case, and change all the users of this API to check against IS_ERR instead. Signed-off-by: Tero Kristo Acked-by: Michael Turquette
