There is no need to init .owner field.
Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"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."

There are some structs and arrays on the driver that are not used
anywhere else. Let's mark them as static.

git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into clk-next-sunxi
Allwinner clocks additions for 3.17
This pull request adds support for the clocks found in the newly supported
Allwinner A23 clocks.

This patch adds "allwinner,sun8i-a23-apb0-gates-clk", a A23 specific
compatible to the sun6i-a31-apb0-gates clock driver, along with the
gate bitmap.

sun6i-apb0-gates uses the "clock-indices" DT property to indicate
valid gate bits or holes in between. However, the rest of sunxi
clock drivers use bitmaps for this purpose.
This patch modifies sun6i-apb0-gates to use bitmaps as well, to be
consistent with the sunxi platform. Also add the missing call to
clk_register_clkdev, so system clock lookups will work.

sun6i-a31-apb0-gates supports using clock-indices for holes between
individual gates. However, the driver passes the number of gates
registered in clk_data->clk_num, which of_clk_src_onecell_get uses
to recognize the range of valid indices a consumer can use.
This patch makes the driver pass the maximum gate index + 1, so
of_clk_src_onecell_get does not complain about indices greater
than gates registered.
This was tested on the A23 SoC, which has a similar APB0 clock,
but has holes for gates to removed IP blocks.

devm_ioremap_resource returns an ERR_PTR value, not NULL, on failure.
A simplified version of the semantic match that finds this problem is as
follows:
// <smpl>
@@
expression e,e1;
statement S;
@@
*e = devm_ioremap_resource(...);
if (!e1) S
// </smpl>

The PRCM (Power/Reset/Clock Management) unit provides several clock
devices:
- AR100 clk: used to clock the Power Management co-processor
- AHB0 clk: used to clock the AHB0 bus
- APB0 clk and gates: used to clk peripherals connected to the APB0 bus
Add support for these clks in a separate driver so that they can be probed
as platform devices instead of registered during early init.
This is needed to be able to probe PRCM MFD subdevices.
