Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

Add check for the return value of clk_enable() in order to catch the
potential exception.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The devm_counter_alloc() function returns NULL on error. It doesn't
return error pointers.

A spare warning was reported for drivers/counter/ti-ecap-capture.c::
sparse warnings: (new ones prefixed by >>)
>> drivers/counter/ti-ecap-capture.c:380:8: sparse: sparse: symbol 'ecap_cnt_pol_array' was not declared. Should it be static?
vim +/ecap_cnt_pol_array +380 drivers/counter/ti-ecap-capture.c
379
> 380 static DEFINE_COUNTER_ARRAY_POLARITY(ecap_cnt_pol_array, ecap_cnt_pol_avail, ECAP_NB_CEVT);
381
The first argument to the DEFINE_COUNTER_ARRAY_POLARITY() macro is a
token serving as the symbol name in the definition of a new
struct counter_array structure. However, this macro actually expands to
two statements::
#define DEFINE_COUNTER_ARRAY_POLARITY(_name, _enums, _length) \
DEFINE_COUNTER_AVAILABLE(_name##_available, _enums); \
struct counter_array _name = { \
.type = COUNTER_COMP_SIGNAL_POLARITY, \
.avail = &(_name##_available), \
.length = (_length), \
}
Because of this, the "static" on line 380 only applies to the first
statement. This patch splits out the DEFINE_COUNTER_AVAILABLE() line
and leaves DEFINE_COUNTER_ARRAY_POLARITY() as a simple structure
definition to avoid issues like this.

ECAP hardware on TI AM62x SoC supports capture feature. It can be used
to timestamp events (falling/rising edges) detected on input signal.
This commit adds capture driver support for ECAP hardware on AM62x SoC.
In the ECAP hardware, capture pin can also be configured to be in
PWM mode. Current implementation only supports capture operating mode.
Hardware also supports timebase sync between multiple instances, but
this driver supports simple independent capture functionality.
