Subject: pinctrl-single: num_maps in generic pinconf support?
Date: Tue, 26 May 2020 14:21:33 +0200 [thread overview]
Message-ID: <20200526122133.GA1454440@x1> (raw)
Hello Haojian and Linus,
For pcs_parse_one_pinctrl_entry() in drivers/pinctrl/pinctrl-single.c,
I see that num_maps is set to 2 if PCS_HAS_PINCONF is enabled:
1057 if (PCS_HAS_PINCONF && function) {
1058 res = pcs_parse_pinconf(pcs, np, function, map);
1059 if (res)
1060 goto free_pingroups;
1061 *num_maps = 2;
1062 } else {
1063 *num_maps = 1;
1064 }
1065 mutex_unlock(&pcs->mutex);
git blame shows me that came from 9dddb4df90d13:
"pinctrl: single: support generic pinconf"
Would you be able to provide any insight as to num_maps needs to be 2
when pinconf is enabled?
thank you,
drew
