From Tony Lindgren: Minimal omap fixes for the -rc series: - A build fix for recently merged omap DRM changes - Regression fixes from the common clock framework conversion for omap4 audio and omap2 reboot - Regression fix for pandaboard WLAN control UART muxing caused by u-boot only muxing essential pins nowadays - Timer iteration fix for CONFIG_OF_DYNAMIC - A section mismatch fix for ocp2scp init * tag 'omap-for-v3.8-rc4/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (306 commits) ARM: OMAP2+: omap4-panda: add UART2 muxing for WiLink shared transport ARM: OMAP2+: DT node Timer iteration fix ARM: OMAP2+: Fix section warning for omap_init_ocp2scp() ARM: OMAP2+: fix build break for omapdrm ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function calls ARM: OMAP4: hwmod_data: Correct IDLEMODE for McPDM ARM: OMAP4: clock data: Lock ABE DPLL on all revisions + Linux 3.8-rc4 Signed-off-by: Olof Johansson <olof@lixom.net>
