Date: Fri, 26 May 2017 15:20:19 +0800 From: David Wu <david.wu@...k-chips.com> To: heiko@...ech.de, linus.walleij@...aro.org Cc: huangtao@...k-chips.com, dianders@...omium.org, linux-rockchip@...ts.infradead.org, linux-gpio@...r.kernel.org, linux-kernel@...r.kernel.org, David Wu <david.wu@...k-chips.com> Subject: [PATCH v2 0/4] Add iomux-route switching support The rk3228, rk3328, rk3399 have an interesting new feature, some things like one specific uart can use multiple pins to output data, but control of that seems to be split. The actual pin config is identical for all pins - each needs to be configured to function 2. Use one pin of a specifc group to be set to its special pinmux function, then configure the corresponding routing bits. If the pinmux setting is wrong for that pin the ip block won't work correctly anyway.
