Merge (part of) tag 'omap-for-v3.19/hwmod-and-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

SoC related changes for omaps including hwmod clean-up for
DSS, and hwmod data for more UARTs and ADC. Also few defconfig
changes to enable devices found on am335x and am437x.

[arnd: I removed the defconfig changes from the branch in order
 to cherry-pick them onto the next/defconfig branch, but I did
 not change the other commits]

* commit '29c4ce17bcad':
  ARM: dts: cm-t3x30: add keypad support
  ARM: OMAP2+: hwmod: AM43x: add hwmod support for ADC on AM43xx
  ARM: DRA7: hwmod data: Add missing UART hwmod data
  ARM: dts: omap4.dtsi: remove dss_fck
  ARM: OMAP4: fix RFBI iclk
  ARM: OMAP4: hwmod: use MODULEMODE properly
  ARM: OMAP4: hwmod: set DSS submodule parent hwmods
  ARM: OMAP5: hwmod: set DSS submodule parent hwmods
  ARM: OMAP2+: hwmod: add parent_hwmod support
