"One more patch to remove io.h from clk-provider.h.We used to need this include when we had clk_readl() and clk_writel(),

clk: Remove io.h from clk-provider.h
16 May, 2019
1 commit
-
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.Found with this grep:
git grep -l clk-provider.h | grep '.c$' | xargs git grep -L 'linux/io.h' | \
xargs git grep -l \

The AXP223 can be used both using the RSB proprietary bus, or a more
traditional I2C bus. The RSB is a faster bus and provides more features
(like some integrity checks on the messages), so it's usually preferrable
to use it, but since it's proprietary, when we want to use the PMIC in a
multi-master setup, the i2c might make sense as well.Let's add that possibility.

I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero:
twl6040 0-004b: Failed to write 2d = 19: -121
And then any following register access will produce errors.
There 2d offset above is register ACCCTL that gets written on twl6040
powerup. With error checking added to the related regcache_sync() call,
the -EREMOTEIO error is reproducable on twl6040 powerup at least
duovero.To fix the error, we need to wait until twl6040 is accessible after the
powerup. Based on tests on omap4 duovero, we need to wait over 8ms after
powerup before register write will complete without failures. Let's also
make sure we warn about possible errors too.Note that we have twl6040_patch[] reg_sequence with the ACCCTL register
configuration and regcache_sync() will write the new value to ACCCTL.Signed-off-by: Tony Lindgren

These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" was applied. With this new feature,
MODULE_*() will be populated even if the callers are built-in.To avoid the build errors, the lines referencing to the undefined
macro must be removed.The complete fix is to remove all MODULE_* and #include
like many "make ... explicitly non-modular" commits did.For now, I am touching only the offending lines.
