From: Tony Lindgren <tony@atomide.com>
Subject: [GIT PULL] few fixes for the v3.19 merge window

Fixes for a few issues found that would be good to get
into -rc1:

- Update SoC revision detection for am43x es1.2

- Fix regression with GPMC timings on 2430sdp for some versions
  of u-boot

- Fix dra7 watchdog compatible property

- Fix am437x-sk-evm LCD timings

- Fix dra7 DSS clock muxing

- Fix dra7-evm voltages

- Remove a unused function prototype for am33xx_clk_init

- Enable AHCI in the omap2plus_defconfig
