[GitHub] [incubator-nuttx] liuchengvbl opened a new pull request #4465: feature: driver: Add a Linux SPI into simulator.

liuchengvbl opened a new pull request #4465:
URL: https://github.com/apache/incubator-nuttx/pull/4465


   ## Summary
   When CONFIG_SIM_SPI is valid, a specified Linux SPI device "spidevN.P" (N is bus number and P is CS number) is attached to nuttx simulator, shown as "spi0" under /dev. One may type "spi" command (need SPITOOL valid) in NSH to control the Linux SPI and exchange data, other devices such sensors can use it to debug in simulator on a Ubuntu PC. Note that a USB<>SPI module (e.g. CH341A/B) should be plugged in to achieve Linux SPI ports.
   
   Change-Id: I275b2c2bbf6d14bcdf514c89efb9a2264d69e9a3
   Signed-off-by: liucheng5 <li...@xiaomi.com>
   
   ## Impact
   Bring an extra step for sim_spi initializing to sim_bringup() procession, after sim_i2cbus initialized.
   
   ## Testing
   Tested with a CH341B USB<>SPI module, in Ubuntu 18.04. Nuttx congifuredd as "./tools/configure.sh -l sim:linuxspi" and ran with "sudo ./nuttx".
   Test0: Use "ls /dev", and found "spi0" in /dev.
   Test1: The Linux SPI device works as a master, use some sensors as slaves.  Use "spi exch" to successfully read and write sensors' registers.
   Test2: Loopback MISO<>MOSI of the USB<>SPI module. Use "spi exch" to successfully receive the the same content as transmitted.

   Since this feature is specific for Linux, it should be removed from macOS CI, @liuchengvbl , please add sim:linuxspi to the black list:
