2015-10-08ARM: dts: Use GPIO constants for flags cells in exynos4412 boardsJavier Martinez Canillas1-7/+8
The board DTS are using numeric values instead of the defined GPIO constanst to express polarity, use them to make the DTS more clear. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Kukjin Kim <kgene@kernel.org>

2014-08-18ARM: dts: ODROID i2c improvements for exynos4412-odroid-commonDaniel Drake1-0/+2
Increase max i2c bus frequency beyond the default for faster data transfers. According to the manual, these faster speeds are only available when the board is wired up the right way. In this case, the vendor kernel has run at this speed for a long time. sda-delay is needed for talking to RTC on PMIC, otherwise the i2c controller never sees an ACK. Strangely the other PMIC i2c slave (the main one) works fine even without this delay. I Chose value 100 to match the vendor kernel.

This patch moves some parts of exynos4412-odroidx.dts to common exynos4412-odroid-common.dtsi file and adds support for Odroid X2 and U2/U3 boards. X2 is same as X, but it has faster SoC module (1.7GHz instead of 1.4GHz), while U2/U3 differs from X2 by different way of routing signals to host USB hub. It also lacks some hw modules not yet supported by those dts files (i.e. LCD & touch panel).
