[PATCH 00/15] Enable compilation of various Renesas drivers with COMPILE_TEST

[Laurent Pinchart]

Hello,

This patch series enables driver compilation with COMPILE_TEST for various
Renesas drivers. The approach taken here is to split the Kconfig depends line
in two, with compile dependencies (if any) on one line and runtime
dependencies (as a list of the platforms on which the hardware can be found)
on another line. The runtime dependencies line is extended with
|| COMPILE_TEST to enable test compilation. This clearly identifies compile
dependencies, and allow test compilation while not clobbering the
configuration menu with useless options in the normal case.

The patches are based on top of v3.13-rc1. To avoid build warnings or errors
during bisection the following patches sent to linux-sh and appropriate
mailing lists should be applied first:

serial: sh-sci: Fix warnings due to improper casts and printk formats
DMA: shdma: Fix warnings due to improper casts and printk formats
DMA: shdma: Fix warnings due to declared but unused symbols
DMA: shdma: Make sh_dmae_pm static
v4l: sh_vou: Fix warnings due to improper casts and printk formats
mmc: sh_mmcif: Factorize DMA channel request and configuration code
mmc: sh_mmcif: Fix compilation warning on 64-bit platforms
mtd: sh_flctl: Fix warnings due to improper casts
fbdev: sh_mobile_lcdcfb: Don't use plain 0 as NULL pointer
spi: sh-msiof: Fix warnings due to improper casts
spi: rcar: Fix uninitialized variable warning
spi: rcar: Fix pointer cast in the remove function

For convenience I've pushed the whole series and its prerequisites to my git
tree at

	git://linuxtv.org/pinchartl/fbdev.git clocks/ccf/multiarch-drivers

The patches will need to go through their respective subsystem's trees. To
help me tracking the mainlining state I'd appreciate if the respective
maintainers could notify me when applying the patches to their trees. Before
doing so I'd like to get an ack from Mark Brown and/or Russell King on the
approach.

Hi David,

Could you please pick this patch up for v3.14 ?

I'm not David, but I pushed your patch over a week ago. I guess I forgot
to warn you. Sorry!
