clk: clk-max77686: Clean clkdev lookup leak and use devm

2019-02-06T18:35:03+00:00

clk-max77686 never clean clkdev lookup at remove. This can cause
oops if clk-max77686 is removed and inserted again. Fix leak by
using new devm clkdev lookup registration. Simplify also error
path by using new devm_of_clk_add_hw_provider.

clk: max77686: constify clk_ops structure

2018-11-06T17:41:29+00:00

The clk_ops structure is only stored in the ops field of a
clk_init_data structure.  This field is const, so the clk_ops
structure can be const as well.

Identified and transformed using Coccinelle.

clk: max77686: fix number of clocks setup for clk_hw based registration

2016-10-17T22:31:59+00:00

The commit 9b4cac33adc7 ("clk: max77686: Migrate to clk_hw based OF and
registration APIs") converted the driver to use the new provider API to
register clocks using clk_hw.

But unfortunately, in the conversion it missed to set the num_clks value
which lead to the following error when trying to register a clk provider:

[    1.963782] of_clk_max77686_get: invalid index 0
[    1.967460] ERROR: could not get clock /rtc@10070000:rtc_src(1)
[    1.973638] s3c-rtc 10070000.rtc: failed to find rtc source clock

Fix it by correctly set the max77686_clk_driver_data num_clks member.

clk: max77686: Migrate to clk_hw based OF and registration APIs

2016-08-18T23:42:36+00:00

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.

clk: max77686: Add support for MAX77620 clocks

2016-08-15T22:39:32+00:00

Maxim Max77620 has one 32KHz clock output and the clock HW
IP used on this PMIC is same as what it is there in the MAX77686.

Add clock driver support for MAX77620 on the MAX77686 driver.

clk: max77686: Combine Maxim max77686 and max77802 driver

2016-08-15T22:32:41+00:00

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.

drivers/clk: include for clk-max77xxx modular code

2015-06-16T18:12:25+00:00

These files are built off of the tristate COMMON_CLK_MAX77686 and
COMMON_CLK_MAX77802 respectively.  They also contains modular function
calls so they should explicitly include module.h to avoid compile
breakage during header shuffles done in the future.

clk: Remove .owner field for driver

2014-09-26T00:43:31+00:00

There is no need to init .owner field.

Based on the patch from Peter Griffin 
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."
