Subject: reset: reset-hisilicon: also handle #reset-cells = <2>
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=53c3e386063b9e1ab955d4658a035f1eea8a1cc0;p=u-boot.git

reset: reset-hisilicon: also handle #reset-cells = <2>

It's also valid to have #reset-cells = <2> while the third arg defaults
to ASSERT_SET.
