-Subject: [PATCH 03/76] clk: mediatek: Add reset controller support
-
-The pericfg and infracfg units also provide reset lines to several
-other SoC internal units. This adds a function which can be called
-from the pericfg and infracfg initialization functions which will
-register the reset controller using reset_controller_register. The
-reset controller will provide support for resetting the units
-connected to the pericfg and infracfg controller. The units resetted
-by this controller can use the standard reset device tree binding
-to gain access to the reset lines.
