ARM: dts: rockchip: move shared tinker-board nodes to a common dtsi Tinker Board and Tinker Board S share most of their components, so should also not replicate these for each variant. So move them to a shared dtsi that then can get included by both boards. Signed-off-by: David Summers <beagleboard@davidjohnsummers.uk> Signed-off-by: Heiko Stuebner <heiko@sntech.de>

ARM: dts: rockchip: Fix SD card detection on rk3288-tinker The Problem: On ASUS Tinker Board S, when booting from the eMMC, and there is card in the sd slot, there are constant errors. Also when warm reboot, uboot can not access the sd slot Cause: Identified by Robin Murphy @ ARM. The Card Detect on rk3288 devices is pulled up by vccio-sd; so when the regulator powers this off, card detect gives spurious errors. A second problem, is during power down, vccio-sd apprears to be powered down. This causes a problem when warm rebooting from the sd card. This was identified by Jonas Karlman. History: A common fault on these rk3288 board, which impliment the reference design. When this arose before: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/281153.html And Ulf and Jaehoon clearly said this was a broken card detect design, which should be solved via polling Solution: Hence broken-cd is set as a property. This cures the errors. The powering down of vccio-sd during reboot is cured by adding regulator-boot-on. This solutions has been fairly widely reviewed and tested.
