From d16645054d2f55e4011c9725ddf2dbe6177e942a Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Fri, 21 Jul 2017 09:38:36 -0700 Subject: [PATCH 01/22] dt-bindings: Drop k2g genpd device ID macros Commit 7cc119f29b19 ("dt-bindings: Add TI SCI PM Domains") introduced a number of K2G_DEV_x macros to represent each device ID available on the K2G platform for use by the genpd, clock, and reset drivers. Rather than use these macros, which are only used in the device tree for property values and not actually used by the drivers, let's just use the device ID number directly in the device tree to avoid macro bloat.

OMAP based SoCs do not require the clock property since hwmod already handles creating a "fck" clock thats accessible to drivers. However, this isn't the case for 66AK2G which makes the clocks property require for that SoC. 66AK2G requires a new property. Therefore, update the binding to also make this property requirement clear. Also clarify that for OMAP based SoCs ti,hwmod is a required property.

Add the DT node for this DSP processor sub-system. The DT node has a new property 'power-domains' and no 'clocks' properties, and uses slightly different property values for 'resets' compared to other Keystone 2 SoCs. The processor does not have an MMU, and uses various IPC Generation registers and shared memory for inter-processor communication. The alias with a stem 'rproc' has also been added for the DSP, it provides a fixed remoteproc id for the DSP processor. Signed-off-by: Andrew F.
