[PATCH v2] arm64: dts: fsd: fix PUD values as per FSD HW UM

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

 



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.
