i2c: sh_mobile: remove platform_data

2017-06-02T20:50:13Z

No platform currently upstream makes use of this platform_data anymore. The ones that did are converted to DT meanwhile. So, remove it. The old platforms likely don't have the 'clks_per_cnt' feature, otherwise it would have been implemented by now. And in the unlikely case they need to setup a different bus speed, we should rather go for a generic i2c platform data just for that.

i2c: i2c-sh_mobile: support I2C hardware block with a faster operating clock

2012-11-16T08:09:12Z

On newer SH-/R-Mobile SoCs, a clock supply to the I2C hardware block, which is used to generate the SCL clock output, is getting faster than before, while on the other hand, the SCL clock control registers, ICCH and ICCL, stay unchanged in 9-bit-wide (8+1). On such silicons, the internal SCL clock counter gets incremented every 2 clocks of the operating clock. This patch makes it configurable through platform data.
