support
> 
> The Realtek Otto switch platform consists of four different series
> 
> - RTL838x aka maple   : 28 port 1G Switches
> - RTL839x aka cypress : 52 port 1G Switches
> - RTL930x aka longan  : 28 port 1G/2.5G/10G Switches
> - RTL931x aka mango   : 56 port 1G/2.5G/10G Switches
> 
> While the MDIO hardware polling unit and its necessity for the MAC 
> layer was always well known, no detailed documentation was available.
> For this series the MDIO bus was inspected with a logic analyzer for 
> a better understanding how polling and kernel access interact on the 
> bus. All this will be explained now in the driver comments.
> 
> This patch series adds support for the RTL83xx devices. For this
> 
> - Enhance device tree binding.
> - Add special handling for limitations enforced by hardware polling.
>   These already have minor side effects on RTL93xx devices but are even
>   more critical for the RTL83xx hardware.
> - Add RTL83xx coding.
