Merge tag 'omap-for-v4.7/legacy-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical
Merge "omap legacy boot vs dt boot fixes for v4.7 merge window" from Tony Lindgren: Legacy booting vs device tree booting fixes for omaps for v4.7 merge window. These are not considered urgent fixes enough for the v4.6-rc cycle, but we need them in v4.7 in order to drop the last remaining board-*.c files for omap3 for v4.8 merge window. On Nokia N900, we need to pass the MMC slot names for the legacy user space to work. Let's do that using auxdata as the driver is setting up things already with the pdata for legacy booting. Then we can later on discuss if we may want to have some generic binding describing where the MMC slots are on the device. N900 also has had the ir-rx51 device driver unusable with multiarch for a long time. Let's pass the dmtimer data in pdata for the driver to get it going again. Then once things are working, we can eventually change the driver to use just hrtimer and PWM framework. The driver changes will be queued separately. * tag 'omap-for-v4.7/legacy-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: n900 needs MMC slot names for legacy user space ARM: OMAP2+: Add more functions to pwm pdata for ir-rx51
