Merge tag 'omap-for-v4.13/gpmc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
Few improvments for GPMC (General Purpose Memory Controller) found on TI SoCs to produce an error for missing bank-width and to make the bootloader timing debug output usable for device tree timings. * tag 'omap-for-v4.13/gpmc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: memory: omap-gpmc: add error message if bank-width property is absent memory: omap-gpmc: make dts snippet include semicolon Signed-off-by: Olof Johansson <olof@lixom.net>
