Subject: ARM64: zynqmp: List all i2c muxes as separate buses for ZCU102
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7913a6c770a56f75bba96a1947670a3b58d6b36c;p=thirdparty%2Fu-boot.git

ARM64: zynqmp: List all i2c muxes as separate buses for ZCU102

Simplify work with I2C muxes by definitely i2c bus topology.
Here is example of it:
ZynqMP> i2c bus
Bus 0:	zynq_0
Bus 1:	zynq_0->PCA9544A@0x75:0
Bus 2:	zynq_0->PCA9544A@0x75:1
Bus 3:	zynq_0->PCA9544A@0x75:2
Bus 4:	zynq_1
Bus 5:	zynq_1->PCA9548@0x74:0
Bus 6:	zynq_1->PCA9548@0x74:1
Bus 7:	zynq_1->PCA9548@0x74:2
Bus 8:	zynq_1->PCA9548@0x74:3
Bus 9:	zynq_1->PCA9548@0x74:4
Bus 10:	zynq_1->PCA9548@0x75:0
Bus 11:	zynq_1->PCA9548@0x75:1
Bus 12:	zynq_1->PCA9548@0x75:2
Bus 13:	zynq_1->PCA9548@0x75:3
Bus 14:	zynq_1->PCA9548@0x75:4
Bus 15:	zynq_1->PCA9548@0x75:5
Bus 16:	zynq_1->PCA9548@0x75:6
Bus 17:	zynq_1->PCA9548@0x75:7
