Subject: arm64: dts: fsd: fix PUD values as per FSD HW UM
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=32d0c06801172e258a66ffb5dfad7d5d2b9557a9;p=linux.git

arm64: dts: fsd: fix PUD values as per FSD HW UM

PUD values used for UFS, SPI and UART are not reflecting
the default values recommended by FSD HW UM. Therefore,
changing the same to comply with HW UM recommendation.
