[PATCH 2/2] clk: renesas: rzv2h: Deassert reset on assert timeout

[Biju]

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

If the assert() fails due to timeout error, set the reset register bit
back to deasserted state. This change is needed especially for handling
assert error in suspend() callback that expect the device to be in
operational state in case of failure.
