Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs. A handful of driver changes this time around. The larger changes are: - Reset drivers for hi3660 and zx2967 - AHCI driver for Davinci, acked by Tejun and brought in here due to platform dependencies - Cleanups of atmel-ebi (External Bus Interface) - Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc register range on the SoCs) - PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (53 commits) soc: samsung: pmu: Add register defines for pad retention control reset: make zx2967 explicitly non-modular reset: core: fix reset_control_put soc: samsung: pm_domains: Read domain name from the new label property soc: samsung: pm_domains: Remove message about failed memory allocation soc: samsung: pm_domains: Remove unused name field soc: samsung: pm_domains: Use full names in subdomains registration log sata: ahci-da850: un-hardcode the MPY bits sata: ahci-da850: add a workaround for controller instability sata: ahci: export ahci_do_hardreset() locally sata: ahci-da850: implement a workaround for the softreset quirk sata: ahci-da850: add device tree match table sata: ahci-da850: get the sata clock using a connection id soc: samsung: pmu: Remove duplicated define for ARM_L2_OPTION register memory: atmel-ebi: Enable the SMC clock if specified soc: samsung: pmu: Remove unused and duplicated defines memory: atmel-ebi: Properly handle multiple reference to the same CS memory: atmel-ebi: Fix the test to enable generic SMC logic soc: samsung: pm_domains: Add new Exynos5433 compatible soc: samsung: pmu: Add dummy support for Exynos5433 SoC ...
2017-02-03firmware: qcom: scm: Fix interrupted SCM callsAndy Gross1-3/+10
This patch adds a Qualcomm specific quirk to the arm_smccc_smc call. On Qualcomm ARM64 platforms, the SMC call can return before it has completed. If this occurs, the call can be restarted, but it requires using the returned session ID value from the interrupted SMC call. The quirk stores off the session ID from the interrupted call in the quirk structure so that it can be used by the caller. This patch folds in a fix given by Sricharan R: https://lkml.org/lkml/2016/9/28/272 Signed-off-by: Andy Gross <andy.gross@linaro.org> Reviewed-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
2017-01-16firmware: qcom_scm: Add set remote state APIAndy Gross1-0/+16
This patch adds a set remote state SCM API. This will be used by the Venus and GPU subsystems to set state on the remote processors. This work was based on two patch sets by Jordan Crouse and Stanimir Varbanov. Signed-off-by: Andy Gross <andy.gross@linaro.org>
