[PATCH v2 0/2] clk: renesas: rz{g2l,v2h}: Deassert reset on assert timeout

Posted by Biju 1 month ago

From: Biju Das <biju.das.jz@bp.renesas.com>

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.

Ref:
[1] https://lore.kernel.org/all/b417865397822176e83bca6b9d8094fe92ff2451.camel@pengutronix.de/

v1->v2:
 * Added the variable "mon" and used in readl_poll_timeout_atomic()
   instead of reusing "value".
 * Dropped the assert check in error path and simplified value using xor.
 * Added Rb tag from Geert.
