This release adds the following drivers and integrates support into the Cortina Access Presidio Engineering Board:
CAxxxx SoC eMMC/SD controller CAxxxx SoC I2C controller CAxxxx Soc LED controller CAxxxx SPI NAND and NOR controller
Changes in v6: - Add I2C DT binding document
Changes in v5: - Rebase code basis on v2020.04-rc5 which has already incorporated CAxxxx eMMC initial baseline - Rebase on codebase basis v2020.04-rc5 which already incorporated initial baseline of eMMC DT information - NAND support removed from presidio-asic board DT.
Changes in v4: - Rename DT compatible name - Remove uneccessary if-statement to support 8-bit buswidth - Remove redundant error msg - Use symbolic constants in switch statement - Change DT compatiblity name to match change in driver's name - Remove unused io_ds and fifo_mode fields from DT - Utilize standard I2C macros from <i2c.h> - Return ETIMEDOUT in funcs that can timeout - Return i2c_xfer_init() result to caller of i2c_read() if it fails within i2c_read() execution - Fix misc. style guide conformance issues - Use printf() to report i2c_xfer() runtime errors instead of debug() - remove unused macros - remove cortina prefix from macros - remove use BSS variable - further cleanup to meet code style guidelines - add additinal struct comments - rename DT blink rate symbol - rename DT blink rate symbol
Changes in v3: - Fixup syntax issues related to checkpatch.pl cleanup
Changes in v2: - Add I2C controller - Add LED controller - Add SPI NAND and NOR controller
