1 Qualcomm I2C controller
4 - reg : Offset and length of the register region for the device named in
5 reg-names and has the same index.
6 - reg-names : Register region name(s) referenced in reg above
7 "qup_phys_addr" : Physical address of QUP register space.
8 - compatible : should be "qcom,i2c-msm-v2"
9 - interrupts : Interrupt number which correspond to the entry with the same
10 index in interrupt-names.
11 - interrupt-names: QUP core interrupt name(s) referenced in interrupts above
12 "qup_irq" : QUP interrupt used by the controller.
13 - dmas : DMA engine API's parameters for blsp.
14 <[phandle of the dma controller] [pipe index] [number of descriptors]
15 [sps_connect flags] [sps_register_event flags]>;
16 - dma-names : dma channel names.
17 - qcom,clk-freq-out : Desired I2C bus clock frequency in Hz
18 - qcom,clk-freq-in : Supplied core clock frequency in Hz.
19 - qcom,i2c-dat : specifies GPIO which corresponds to the I2C data line.
20 - qcom,i2c-clk : specifies GPIO which corresponds to the I2C clock line.
23 - The desired bus-number is specified by an alias with the following format:
24 'i2c{n}' where n is the bus number.
27 - qcom,noise-rjct-scl : number of low samples on clock line to consider it low.
28 When missing default to 0.
29 - qcom,noise-rjct-sda : number of low samples on data line to consider it low.
30 When missing default to 0.
31 - qcom,disable-dma : disables DMA transfer mode.
32 - qcom,master-id : Master-port value used on voting for the clock path.
33 - qcom,high-time-clk-div : high time divider value to configure clk-ctl
34 register. When missing, default to the value given in driver.
35 - qcom,fs-clk-div: fs divider value to configure clk-ctl register. When
36 missing, default to the value given in driver.
