Subject: power: regulator: Convert regulators_enable_boot_on/off() to regulator_post_probe
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/%7B%7B%20%24.Site.BaseURL%20%7D%7Dposts/index.xml?a=commitdiff_plain;h=332e0a0148915c994bda9128cb2bb0a0f14e6ec8;p=u-boot.git

power: regulator: Convert regulators_enable_boot_on/off() to regulator_post_probe

Turn regulators_enable_boot_on() and regulators_enable_boot_off() into
empty functions. Implement matching functionality in regulator_post_probe()
instead. The regulator_post_probe() is called for all regulators after they
probe, and regulators that have regulator-always-on or regulator-boot-on DT
properties now always probe due to DM_FLAG_PROBE_AFTER_BIND being set on
such regulators in regulator_post_bind().

Finally, fold regulator_unset() functionality into regulator_autoset().
