Hi. I would like to set BLSP 11 as a UART. It looks like this BLSP can be set to SPI/UART/I2C/UIM according to the BLSP_on_Snapdragon-820_v1.pdf. I started looking at the document "Configure a BLSP Port on APQ8096 Device", but it is unclear how to change BLSP 11. I think that I am looking at the correct msm8996.dtsi for the snapdragon 820. It looks like in this file BLSP11 is configured as a SPI as default:
spi_11: spi@75BA000 { /* BLSP2 QUP6 */
compatible = "qcom,spi-qup-v2";
Is this true? Or am I looking in the wrong location (incorrect file)?
The Inforce_6601_Development_Kit_User_Guide (Table 14 Expansion Connector 1) lists BLSP11 as an I2c, but I don't know if this is the default or not:
Pin Primary Functions Other Functions
18 BLSP11_I2C_SCL CAM2_MI2S_D1 I2C for SMB210 (DNP)
CODEC_MCLK CODEC_MCLK /SPKR_I2S_MCLK(DNP)
Could I get some help, please, setting BLSP11 to a UART? I am using Debian linux for development.
Thanks,
Kim
