X-Git-Tag: v2019.01-rc2~14^2 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=19f8c4dfb6e744a31da59bdd23b24d144152f1dc;p=oweals%2Fu-boot.git cmd: i2c: Fix help output of i2c command. In case SYS_I2C or DM_I2C are defined, then the "i2c " prefix of the "i2c crc32" command is missing. This patch addresses this, so that users can't get confused by the "crc32" command. Without the patch we get => i2c help i2c - I2C sub-system Usage: i2c bus [muxtype:muxaddr:muxchannel] - show I2C bus info crc32 chip address[.0, .1, .2] count - compute CRC32 checksum i2c dev [dev] - show or set current I2C bus [...] With the patch we get => i2c help i2c - I2C sub-system Usage: i2c bus [muxtype:muxaddr:muxchannel] - show I2C bus info i2c crc32 chip address[.0, .1, .2] count - compute CRC32 checksum i2c dev [dev] - show or set current I2C bus ...
