[PATCH 5.15 032/484] arm64: dts: mediatek: mt8183-kukui: Drop bogus output-enable property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chen-Yu Tsai <wenst@xxxxxxxxxxxx>

[ Upstream commit e9a9055fdcdc1e5a27cef118c5b4f09cdd2fa28e ]

The "output-enable" property is set on uart1's RTS pin. This is bogus
because the hardware does not actually have a controllable output
buffer. Secondly, the implementation incorrectly treats this property
as a request to switch the pin to GPIO output. This does not fit the
intended semantic of "output-enable" and it does not have any affect
either because the pin is muxed to the UART function, not the GPIO
function.

Drop the property.
