I plan to move all the whole patchset (except DTS changes) to for-next on 2014-05-15 23:42 if nobody objects until then. @Tony: Is this sufficiently early to get the DTS changes into 3.16 via your tree? Changes since PATCHv4 [0]: * Removed first three patches (HSI Documentation, MAINTAINER file update and hsi-char fix) from the patchset. I added them to for-next already. * Added module parameter pm to the nokia-modem kernel module, which can be used to disable requesting the gpios (needed by fremantle). The same parameter will be used later to enable full-kernel based power management. This is not yet implemented in the driver and would break all existing userspace applications. * Added Tested-By from Ivaylo Dimitrov, who successfully tested it with Maemo fremantle (with some additional patches not directly touching the modem, but needed to boot Maemo). * Export ssi-protocol reset function, so that nokia-n900 can call it if ssi-protocol is built as module. * Updated KConfig, so that n900-modem / ssi-protocol and omap-ssi can be built independently. * Updated KConfig omap-ssi entry to depend on omap3 or compile-test. * Fix build for disabled CONFIG_OF For testing you can either apply this patchset to current mainline kernel or use the n900-modem-support-4 branch available on [1]. Feedback is highly appreciated :) For testing the patchset you should build the kernel with all config entries in the HSI subsystem activated and boot using the updated device tree information (platform data based booting is not supported!). Testing the patchset with ofono works like this: # provide cmt device for ofono ln -sf /sys/bus/hsi/n900-modem /dev/cmt # start ofono ofono --nodetach --debug # enable the modem mdbus2 -s org.ofono /n900_0 org.ofono.Modem.SetProperty Powered true # enable modem's RF parts mdbus2 -s org.ofono /n900_0 org.ofono.Modem.SetProperty Online true # scan for available networks (takes some time) mdbus2 -s org.ofono /n900_0 org.ofono.NetworkRegistration.Scan TODO (post-merge): * Central Message Queue in HSI framework * Remove the hwmod DT hack * Implement proper context loss detection * Implement full N900 modem PM (in-kernel) * Remove wakeline checks (thus removing the FIXMEs) [0] https://lkml.org/lkml/2014/4/25/520 [1] git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-hsi.git -- Sebastian Sebastian Reichel (10): HSI: method to unregister clients from an hsi port HSI: Add channel resource support to HSI clients HSI: export method to (un)register clients HSI: Add common DT binding for HSI client devices HSI: Introduce OMAP SSI driver Documentation: DT: omap-ssi binding documentation HSI: Introduce driver for SSI Protocol HSI: Introduce Nokia N900 modem driver DTS: ARM: OMAP3-N900: Add SSI support DTS: ARM: OMAP3-N900: Add modem support .../devicetree/bindings/hsi/client-devices.txt | 44 + .../devicetree/bindings/hsi/nokia-modem.txt | 57 + Documentation/devicetree/bindings/hsi/omap-ssi.txt | 97 ++ arch/arm/boot/dts/omap3-n900.dts | 65 + arch/arm/boot/dts/omap3.dtsi | 45 + arch/arm/boot/dts/omap34xx.dtsi | 11 + arch/arm/boot/dts/omap36xx.dtsi | 11 + drivers/hsi/Kconfig | 1 + drivers/hsi/Makefile | 1 + drivers/hsi/clients/Kconfig | 17 + drivers/hsi/clients/Makefile | 4 +- drivers/hsi/clients/hsi_char.c | 12 +- drivers/hsi/clients/nokia-modem.c | 285 ++++ drivers/hsi/clients/ssi_protocol.c | 1191 +++++++++++++++++ drivers/hsi/controllers/Kconfig | 19 + drivers/hsi/controllers/Makefile | 6 + drivers/hsi/controllers/omap_ssi.c | 625 +++++++++ drivers/hsi/controllers/omap_ssi.h | 166 +++ drivers/hsi/controllers/omap_ssi_port.c | 1399 ++++++++++++++++++++ drivers/hsi/controllers/omap_ssi_regs.h | 171 +++ drivers/hsi/hsi.c | 275 +++- include/linux/hsi/hsi.h | 39 +- include/linux/hsi/ssi_protocol.h | 42 + 23 files changed, 4566 insertions(+), 17 deletions(-) create mode 100644 Documentation/devicetree/bindings/hsi/client-devices.txt create mode 100644 Documentation/devicetree/bindings/hsi/nokia-modem.txt create mode 100644 Documentation/devicetree/bindings/hsi/omap-ssi.txt create mode 100644 drivers/hsi/clients/nokia-modem.c create mode 100644 drivers/hsi/clients/ssi_protocol.c create mode 100644 drivers/hsi/controllers/Kconfig create mode 100644 drivers/hsi/controllers/Makefile create mode 100644 drivers/hsi/controllers/omap_ssi.c create mode 100644 drivers/hsi/controllers/omap_ssi.h create mode 100644 drivers/hsi/controllers/omap_ssi_port.c create mode 100644 drivers/hsi/controllers/omap_ssi_regs.h create mode 100644 include/linux/hsi/ssi_protocol.h -- 2.0.0.rc0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
