Pull OpenRISC fix from Stafford Horne: "Fix config dependencies for Litex SOC driver causing issues on um" * tag 'for-linus' of git://github.com/openrisc/linux: soc: litex: Properly depend on HAS_IOMEM
2021-01-30soc: litex: Properly depend on HAS_IOMEMDavid Gow
The LiteX SOC controller driver makes use of IOMEM functions like devm_platform_ioremap_resource(), which are only available if CONFIG_HAS_IOMEM is defined. This causes the driver to be enable under make ARCH=um allyesconfig, even though it won't build. By adding a dependency on HAS_IOMEM, the driver will not be enabled on architectures which don't support it.

git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux Pull devfreq updates for 5.11 from Chanwoo Choi: 1. Update devfreq core - Add new devfreq_frequency tracepoint to show the frequency change information. - Add governor feature flag. The devfreq governor is able to set the specific flag in order to support a non-common feature. For example, if the governor supports the 'immutable' feature, don't allow user space to change the governor via sysfs. - Add governor sysfs attribute flag for each sysfs file. Prior to that the devfreq subsystem allowed all of the sysfs files to be accessed regardless of the governor type. But some sysfs fils are not supported by specific devfreq governors. In order to only allow the sysfs files supported by the governor to be accessed, clarify the access permissions of sysfs attributes according to the governor. When adding the devfreq governor, specify the available attribute information by using DEVFREQ_GOV_ATTR_* symbols. The user can read or write the sysfs attributes in accordance to the specified access permissions. - Clean-up the code to reduce duplication for the devfreq tracepoint and to remove redundant governor_name field from struct devfreq. 2. Update exynos-bus.c devfreq driver - Add interconnect API support to the Samsung Exynos Bus Frequency driver, exynos-bus.c. Complementing the devfreq driver with interconnect functionality allows to ensure that the QoS requirements regarding devices accessing the system memory (e.g. video processing devices) will be met and allows to avoid issues like DMA underrun. 3. Update tegra devfreq driver - Add interconnect support and OPP interface to tegra30-devfreq.c. Also, it is to guarantee the QoS requirement of some devices like the display controller. - Move tegra20-devfreq.c from drivers/devfreq/ into drivers/memory/tegra/ in order to use the more proper monitoring feature such as EMC_STAT which is located in drivers/memory/tegra/. - Separate the configuration information for different SoCs in tegra30-devfrqe.c. The tegra30-devfreq.c had been supporting both tegra30-actmon and tegra124-actmon devices. In order to use the more correct configuration data, separate them. - Use dev_err_probe() to handle the deferred probe error in tegra30-devfreq.c. 4.

2020-12-11soc: ti: k3-ringacc: add AM64 DMA rings support.Grygorii Strashko
The DMAs in AM64 have built in rings compared to AM654/J721e/J7200 where a separate and generic ringacc is used. The ring SW interface is similar to ringacc with some major architectural differences, like They are part of the DMA (BCDMA or PKTDMA). They are dual mode rings are modeled as pair of Rings objects which has common configuration and memory buffer, but separate real-time control register sets for each direction mem2dev (forward) and dev2mem (reverse). The ringacc driver must be initialized for DMA rings use with k3_ringacc_dmarings_init() as it is not an independent device as ringacc is. AM64 rings must be requested only using k3_ringacc_request_rings_pair(), and forward ring must always be initialized/configured. After this any other Ringacc APIs can be used without any callers changes.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers Driver changes for omaps for genpd for v5.11 merge window This series of changes allows booting am335x with genpd and device tree data without the legacy platform data. Also at least am437x can be booted with gendp with power domain and dts data. The SoC specific dts changes will be a separate pull request. We need the following driver changes merged before the dts changes can be done: - platform code needs a few improvments to probe l4_wkup first for clocks, and to bail out when there is no platform data - ti-sysc driver needs a non-urgent fix for asserting rstctrl reset only after disabling the clocks, to probe modules with no known control registers, and added quirk handling for gpmc devices - omap-prm driver needs a non-urgent fix for reset status bit, support added for pm_clk, and then we add the rest of am335x power domain data - clock driver for am335x needs to keep l3_main clock enabled with genpd for suspend and resume to work - wkup_m3 remoteproc driver needs support added for reset control if available instead of the legacy pdata callbacks - pm33xx driver needs PM runtime support added for genpd The am335x specific driver changes for the clock, wkup_m3, pm33xx and remoteproc drivers are quite trivial and have not caused merge conflicts in Linux next. I did not get acks for these changes except from Santosh but had already pushed out the branch already at that point.

2020-12-05soc: samsung: exynos-chipid: initialize later - with arch_initcallKrzysztof Kozlowski
The Exynos ChipID driver on Exynos SoCs has only informational purpose - to expose the SoC device in sysfs. No other drivers depend on it so there is really no benefit of initializing it early. Instead, initialize everything with arch_initcall which: 1. Allows to use dev_info() as the SoC bus is present (since core_initcall), 2. Could speed things up because of execution in a SMP environment (after bringing up secondary CPUs, unlike early_initcall), 3. Reduces the amount of work to be done early, when the kernel has to bring up critical devices.
