Subject: MIPS: ralink: manage low reset lines
|
|
|
|
Reset lines with indices smaller than 8 are currently considered invalid
|
|
by the rt2880-reset reset controller.
|
|
|
|
The MT7621 SoC uses a number of these low reset lines. The DTS defines
|
|
reset lines "hsdma", "fe", and "mcm" with respective values 5, 6, and 2.
|
|
As a result of the above restriction, these resets cannot be asserted or
|
|
de-asserted by the reset controller. In cases where the bootloader does
|
|
not de-assert these lines, this results in e.g. the MT7621's internal
|
|
switch staying in reset.
|
|
|
|
Change the reset controller to only ignore the system reset, so all
|
|
reset lines with index greater than 0 are considered valid.
