| Subject: i2c: rcar: use per-device clock |
| |
| Using the same clock for all device instances is non-portable and obtaining |
| clock references by an ID without using a device pointer is discouraged. |
| This is also not needed, because on platforms, where this driver is used, |
| suitable clocks are available for the I2C controllers, that are children of |
| the peripheral clock and just pass its rate 1-to-1 to controllers. This |
| patch switches the driver to obtain references to correct clocks. |
