Hi, Some may remember, that in-kernel modem PM was still on the TODO list for the N9xx modem driver. This patchset adds this by hooking to the phonet interface state. In other words: 'ifconfig phonet0 up' will enable the modem and 'ifconfig phonet0 down' will disable the modem. The actual state is mapped to the carrier state (which was more or less the case already). So using the modem can be done like this now: 0. nokia-modem should be loaded with pm=2 1. ifconfig phonet0 up 2. wait for carrier on phonet0 3. communicate with the modem via isi on phonet0 4. ifconfig phonet0 down The old pm method (exporting the gpios) is still available and still the default for now. The plan is to switch the default pm method in some future kernel release (when support for the simpler interface has been added to ofono). -- Sebastian Sebastian Reichel (5): HSI: nokia-modem: simplify kernel access to gpios HSI: nokia-modem: kernel based PM HSI: ssi-protocol: export modem info via sysfs HSI: nokia-modem: drop support for disabled pm HSI: ssi-protocol: clear carrier flag on open drivers/hsi/clients/nokia-modem.c | 240 +++++++++++++++++++++++++++++++------ drivers/hsi/clients/ssi_protocol.c | 56 ++++++++- include/linux/hsi/ssi_protocol.h | 20 ++++ 3 files changed, 277 insertions(+), 39 deletions(-) -- 2.7.0.rc3 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
