[PATCH 0/2] Add ilitek ili9341 panel driver

[dillon.minfei at gmail.com]

From: Dillon Min <dillon.minfei at gmail.com>

Since the st,sf-tc240t-9370-t dts binding already exist in stm32f429-disco.dts
but, the panel driver didn't get accepted from mainline. it's time to submit
patch fot it.

This driver can support two different interface by different dts bindings:
- spi+dpi, use spi to configure register, dpi for graphic data.
  st,sf-tc240t-9370-t
- only spi, just like tiny/ili9341.c (actually, this part is copy from tiny)

I submited the first patch last year, you can find it at [1].
this patch has one major difference from that one, which is replace the low
level communication way, from spi_sync() to mipi_dbi_{command,
command_stackbuf}() interface, referred from Linus's patch [2].

both the two dpi/dbi interface was tested on stm32f429-disco board, if anyone
want to verify this patch, you need apply the clk patch for this board first,
you can get it from [3]
