Subject: [PATCH] power: reset: at91-poweroff: lookup for proper PMC DT node
Date:   Thu, 26 Sep 2019 13:25:37 +0300

Driver has been enabled also for SAM9X60. At the moment the patch which did
this has been sent to mainline the PMC for SAM9X60 wasn't integrated.
SAM9X60 has a new PMC compatible (see commit 01e2113de9a5
("clk: at91: add sam9x60 pmc driver")). Do to this we have to
look for proper PMC compatible here, in SHDWC driver.
