in git commit process, with changes log after that. the log will not
show in commit messages, but will exist in git patchs, just showing for
reviewers ?
Sorry I was not enough clear. Add --- after your signed-off and add your
log change after
i will try this tomorrow, resubmit it.

[PATCH 3/4]: ARM: dts: stm32: enable stmpe811 on stm32429-disco
V2:
patch 3: remove unused id, blocks, irq-trigger
V1:
patch 4: fix read touch screen xyz timeout bug
patch 3: enable stmpe_touchscreen on stm32f429-disco board
patch 2: add i2c3 pin mux for stm32f4
patch 1: add i2c3 controller interface for stm32f4
Good idea to add changes log for this patch. But this log has to be
placed after "---" below. This log has not to appear in your commit
message. Furthermore, you should only add changes for this patch
without talking about other patches .
