[PATCH 0/2] pinctrl: aspeed: Make AST2700 SoC1 JTAG master TRST optional

[Billy Tsai]

The JTAGM1 pin group of the AST2700 SoC1 includes ball D12, which
carries the TRST signal. TRST is an optional signal for a JTAG master:
designs that do not wire it may need the D12 ball for other functions,
but with TRST embedded in the group they cannot use the JTAG master at
all.

Split D12 into a new JTAGM1TRST group under the existing JTAGM1
function, so TRST is only muxed when a board explicitly requests it.
Patch 1 adds the new group to the device tree binding and patch 2
splits the group in the driver.

Note that this changes the meaning of the existing JTAGM1 group: boards
that do use TRST now need to select both the JTAGM1 and JTAGM1TRST
groups.
