* [patch 0/1] Kirwood: Add Iomega Iconnect support @ 2012-04-16 22:05 Arnaud Patard (Rtp) 2012-04-16 22:05 ` [patch 1/1] kirkwood: Add iconnect support Arnaud Patard (Rtp) 0 siblings, 1 reply; 4+ messages in thread From: Arnaud Patard (Rtp) @ 2012-04-16 22:05 UTC (permalink / raw) To: linux-arm-kernel The following patch is adding support for Iomaga Iconnect kirkwood box. It has tested against arm-soc#for-next of some days ago and with ARM_APPENDED_DTB as the uboot I have on this device doesn't support device tree. The DTS file only handles the serial port as it seems it's the only device with OF support [ rtc-mv is converted too but it's already handled by kirkwood.dtsi ] Arnaud Patard ^ permalink raw reply [flat|nested] 4+ messages in thread
