pinctrl: gemini: Support drive strength setting
The Gemini pin controller can set drive strength for a few select groups of pins (not individually). Implement this for GMAC0 and 1 (ethernet ports), IDE and PCI. Cc: devicetree@vger.kernel.org Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
