Subject: [PATCH v1 0/3] reset: npcm: add NPCM reset driver support
Date: Fri, 25 Oct 2019 00:47:43 +0300 [thread overview]
Message-ID: <20191024214746.88431-1-tmaimon77@gmail.com> (raw)
This patch set adds reset controller support
for the Nuvoton NPCM Baseboard Management Controller (BMC).
Apart of controlling all NPCM BMC reset module lines the NPCM reset driver
support NPCM BMC software reset to restarting the NPCM BMC.
Supporting NPCM USB-PHY reset as follow:
NPCM BMC USB-PHY connected to two modules USB device (UDC) and USB host.
If we will restart the USB-PHY at the UDC probe and later the
USB host probe will restart USB-PHY again it will disable the UDC
and vice versa.
The solution is to reset the USB-PHY at the reset probe stage before
the UDC and the USB host are initializing.
NPCM reset driver tested on NPCM750 evaluation board.
