Merge tag 'at91-fixes' of git://github.com/at91linux/linux-at91 into fixes
From Nicolas Ferre: Here are fixes for AT91 that are mainly related to device tree. One RM9200 setup option is the only C code change. Some documentation changes can clarify the pinctrl use. Then, some defconfig modifications are allowing the affected platforms to boot. * tag 'at91-fixes' of git://github.com/at91linux/linux-at91: ARM: at91/dts: correct comment in at91sam9x5.dtsi for mii ARM: at91/at91_dt_defconfig: add at91sam9n12 SoC to DT defconfig ARM: at91/at91_dt_defconfig: remove memory specification to cmdline ARM: at91/dts: add macb mii pinctrl config for kizbox ARM: at91: rm9200: remake the BGA as default version ARM: at91: fix gpios on i2c-gpio for RM9200 DT ARM: at91/at91sam9x5 DTS: add SCK USART pins ARM: at91/at91sam9x5 DTS: correct wrong PIO BANK values on u(s)arts ARM: at91/at91-pinctrl documentation: fix typo and add some details
