Hi all,
V1 ---> V2:
1. delete the patch "arch: arm64: dts: add overlay dts file" because it is improper
to add into kernel source.
2. modify the patch " i2c: cadence: do not clear bus_hold_flag in mrecv" by adding
a I2C_M_NOSTART flag check according to Shubhrajyoti's suggestion. And test it at
zcu102 board (read bus 0x8 device 0x65 (ucd10120) register 0xd6)as below:
Before applying this patch:
root at xilinx-zynq:~# i2cget -f -y 0x8 0x65 0xd6
0xff
After applying this patch:
root at xilinx-zynq:~# i2cget -f -y 0x8 0x65 0xd6
0x05
Thanks,
Quanyang
