The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and Rockchips SoCs see some further updates" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (76 commits) misc: sram: remove useless #ifdef drivers: psci: Allow PSCI node to be disabled drivers: psci: PSCI checker module soc: renesas: Identify SoC and register with the SoC bus firmware: qcom: scm: Return PTR_ERR when devm_clk_get fails firmware: qcom: scm: Remove core, iface and bus clocks dependency dt-bindings: firmware: scm: Add MSM8996 DT bindings memory: da8xx-ddrctl: drop the call to of_flat_dt_get_machine_name() bus: da8xx-mstpri: drop the call to of_flat_dt_get_machine_name() ARM: shmobile: Document DT bindings for Product Register soc: renesas: rcar-sysc: add R8A7745 support reset: Add Tegra BPMP reset driver dt-bindings: firmware: Allow child nodes inside the Tegra BPMP dt-bindings: Add power domains to Tegra BPMP firmware firmware: tegra: Add BPMP support firmware: tegra: Add IVC library dt-bindings: firmware: Add bindings for Tegra BPMP mailbox: tegra-hsp: Use after free in tegra_hsp_remove_doorbells() mailbox: Add Tegra HSP driver firmware: arm_scpi: add support for pre-v1.0 SCPI compatible ... 2016-11-19T02:32:57+00:00 Olof Johansson olof@lixom.net 2016-11-19T02:32:57+00:00 urn:sha1:84f1f0c199fdbdf11eddb8da07d8cd9dcfdaeeb4 bus: Add Tegra GMI support This provides a driver to enable the use of the Generic Memory Interface found on Tegra SoCs that can host various types of high-speed devices. * tag 'tegra-for-4.10-bus' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: bus: Add support for Tegra Generic Memory Interface dt/bindings: Add bindings for Tegra GMI controller Signed-off-by: Olof Johansson <olof@lixom.net> 2016-11-15T16:27:53+00:00 Mirza Krak mirza.krak@gmail.com 2016-11-07T08:30:05+00:00 urn:sha1:40eb47767852a9122ef99a48f8d208ec6327e07f The Generic Memory Interface bus can be used to connect high-speed devices such as NOR flash, FPGAs, DSPs...

This was tested with the SMSC9112 ethernet on the APQ8060 Dragonboard sitting on top of the SLOW CS2. Some of my understanding if very vague and based on guesses and extrapolations: the documentation in APQ8060 Qualcomm Application Processor User Guide 80-N7150-14 Rev. A describes select features but does not document the register bit fields.

The exports have been merged into v4.8-rc1, so the driver can now be built as a module again.

The purpose of the bus driver is to register child devices that are accessed via the ACONNECT bus and through the device parent child relationship, ensure that the appropriate power domain and clocks are enabled for the ACONNECT when any of the child devices are active. Hence, the ACONNECT driver simply enables runtime-pm for the ACONNECT device so that when a child device is resumed, it will enable the power-domain and clocks associated with the ACONNECT.
