| Subject: [PATCH 239/299] ARM: dts: lager: rename and reindex i2cexio |
| |
| The rename from i2cexio to i2cexio0 is in preparation for adding |
| i2cexio1 which will use the demuxer for IIC1/I2C1. |
| |
| The reindexing from i2c8 to i2c10 is to allow space for grouping of |
| additional GPIO buses to be added by follow-up patches to support demuxing |
| of other i2c buses. |
| |
| Also note that fallback to GPIO is not provided by the hardware for IIC0/I2C0. |
