Add a device-tree property use-lvl-write-cache that will cause writes to lvl to be cached instead of read from lvl before each write. This is required on some platforms that have the register implemented as dual read/write (such as Baytrail). Prior to this fix the blue USB port on the Minnowboard Max was unusable since USB_HOST_EN0 was set high then immediately set low when USB_HOST_EN1 was written. This also resolves the 'gpio clear | set' command warning like: "Warning: value of pin is still 0" Signed-off-by: George McCollister <george.mccollister@gmail.com> <rebased on latest origin/master, fixed all baytrail boards> Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Stefan Roese <sr@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>
