From f12ecbe2ea3c01b61e93af815723939a27511abc Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Tue, 15 Oct 2013 12:37:50 +0530 Subject: ARM: dts: omap: Add reset/idle on init bindings for OMAP On OMAP we have co-processor IPs, memory controllers, GPIOs which control regulators and power switches to PMIC, and SoC internal Bus IPs, some or most of which should either not be reset or idled or both at init. (In some cases there are erratas which prevent an IP from being reset) Have a way to pass this information from DT. Update the am33xx/omap4 and omap5 dtsi files with the new bindings for modules which either should not be idled. reset or both. A later patch would cleanup the same information that exists today as part of the hwmod data files.

This changes the i2c ID each bus is registered with in i2c-dev interface. As a result of this, many userspace tools break and there is no consistent manner to fix the same if the i2c dev interface have no consistent numbering. Since this could happen for other OMAP derivatives, provide i2c alias for all OMAP3+ SoCs to allow ordering the i2c devices correctly.
