	Hi Simon, Magnus,

This patch series adds support for the 4 MSIOF channels on SH-Mobile
AG5.

It has been tested (TX only) using MSIOF1 on the CN21 test connector.
RX hasn't been tested, as there are one-directional buffers between the
real MSIOF interface on high-density connector CN8 and the CN21 test
connector.

Functionality-wise, this depends on the bindings in "[PATCH] spi:
sh-msiof: Add support for SH-Mobile AG5", and pinctrl in "[PATCH]
pinctrl: sh-pfc: sh73a0: Add MSIOF support".

Thanks!

The 4 MSIOF clocks are MSTP clocks, and children of the SUB clock.
