Thank you, I have merged this entire series into
the platform-drivers-x86-simatic-ipc branch now:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=platform-drivers-x86-simatic-ipc
I did make 2 small changes to patch 3/3 while merging:
1. Only decend into the siemens subdir if CONFIG_SIEMENS_SIMATIC_IPC is set:
--- a/drivers/platform/x86/Makefile
+++ b/drivers/platform/x86/Makefile
@@ -131,7 +131,7 @@ obj-$(CONFIG_INTEL_SCU_IPC_UTIL) += intel_scu_ipcutil.o
obj-$(CONFIG_X86_INTEL_LPSS) += pmc_atom.o
# Siemens Simatic Industrial PCs
-obj-y += siemens/
+obj-$(CONFIG_SIEMENS_SIMATIC_IPC) += siemens/
# Winmate
obj-$(CONFIG_WINMATE_FM07_KEYS) += winmate-fm07-keys.o
2. Move the "default SIEMENS_SIMATIC_IPC*" lines to directly under
the "tristate ..." lines as suggested by Andy.
Note it will show up there once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
merged into the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
