-Subject: [PATCH] clk: qcom: reset: Allow specifying custom reset delay
-
-The amount of time required between asserting and deasserting the reset
-signal can vary depending on the involved hardware component. Sometimes
-1 us might not be enough and a larger delay is necessary to conform to
-the specifications.
-
-Usually this is worked around in the consuming drivers, by replacing
-reset_control_reset() with a sequence of reset_control_assert(), waiting
-for a custom delay, followed by reset_control_deassert().
-
-However, in some cases the driver making use of the reset is generic and
-can be used with different reset controllers. In this case the reset
-time requirement is better handled directly by the reset controller
-driver.
-
-Make this possible by adding an "udelay" field to the qcom_reset_map
-that allows setting a different reset delay (in microseconds).
