ARM: OMAP2+: hwmod code and data changes for v4.2
Several OMAP2+ hwmod changes for v4.2. One patch cleans up a nasty
interaction between the OMAP GPMC and the hwmod code when debugging is
enabled. IP block integration data has been added for the AM43xx EMIF
RAM controller. There's also a fix for the omap-aes driver when used in
QEMU. And finally, some changes to the OMAP3 hwmod code to support the
use of the security IP blocks (AES and SHA) on GP devices, or when they've
specifically been enabled in the DT data.
Basic build, boot, and power management test results are here:
