Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs. Cc: Kelvin Cheung <keguang.zhang@gmail.com> Signed-off-by:

Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs. We also remove some __init markings in header files as they're useless and we're in the area. Tested-by:

Maxim has used the same clock IP on multiple PMICs like MAX77686, MAX77802, MAX77620. Only differences are the number of clocks from these PMICs like MAX77686 has 3 clocks output, MAX776802 have two clock output and MAX77620 has one clock output. Add clock binding details and DT example for the MAX77620. Signed-off-by:

The clock IP used on the Maxim PMICs max77686 and max77802 are same. The configuration of clock register is also same except the number of clocks. Define the common DT binding file for the clocks of Maxim PMICs MAX77686 and MAX77802. For this, remove the separate DT binding document file for maxim,max77802 and move all information to maxim,max77686 DT binding document. Signed-off-by:

The clock IP used on the Maxim PMICs max77686 and max77802 are same. The configuration of clock register is also same except the number of clocks. Part of common code utilisation, there is 3 files for these chips clock driver, one for common and two files for driver registration. Combine both drivers into single file and move common code into same common file reduces the 2 files and make max77686 and max77802 clock driver in single fine. This driver does not depends on the parent driver structure. The regmap handle is acquired through regmap APIs for the register access. This combination of driver helps on adding clock driver for different Maxim PMICs which has similar clock IP like MAX77620 and MAX20024. Signed-off-by:

This function is only called by builtin code, but we always exported it and had marked it as __init before commit e4eda8e0 (clk: remove exported function from __init section, 2013-01-06) removed that marking. Given that it isn't used by modules, lets unexport it and add back __init. Cc: Denis Efremov <yefremov.denis@gmail.com> Signed-off-by:

Before commit 0861e5b8 (clk: Add clk_hw OF clk providers, 2016-02-05) __of_clk_get_from_provider() would return an error pointer of the provider's choosing if there was a provider registered and EPROBE_DEFER otherwise. After that commit, it would return EPROBE_DEFER regardless of whether or not the provider returned an error. This is odd and can lead to behavior where clk consumers keep probe deferring when they should be seeing some other error. Let's restore the previous behavior where we only return EPROBE_DEFER when there isn't a provider in our of_clk_providers list. Otherwise, return the error from the last provider we find that matches the node. Reported-by:

These clocks are the ones which will be used as source for the peripherals of the Armada 3700 SoC. On this SoC there is two blocks of clocks: the North bridge one and the South bridge one. Most of them are gatable. Most of the time their rate are their parent rated divided by a ratio depending of two registers. Their parent can be choose between the TBG clocks for most of them. However, some of them can't choose their parent or directly depend of the xtal clocks. Other ones do not use exactly the same pattern to find the ratio between their parent rate and their rate. For these reason each clock is a composite clock and the operations they use are different depending of the clock. According to the datasheet it would be possible to select the parent clock and the ratio, however currently the driver does not support it. Signed-off-by:

The driver is to provide the functional clock to OMAP4/5 McPDM. The clock is named as pdmclk in the documentations so change the function names, structure names and variables to align with this. At the same time rename the driver from "twl6040-clk" to "twl6040-pdmclk". This can be done w/o regression since the clock driver is not in use at the moment, the MFD core driver is not even registering the device for it. Signed-off-by:

In order ot be able to use the pdmclk clock via DT it need to be registered as of_clk_provide. Since the twl6040 clock driver does not have it's own DT node, use the parent's node for registering. Signed-off-by:
