2021-01-27misc: pti: Remove driver for deprecated platformAndy Shevchenko1-13/+0
Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.

2020-09-10misc: hisi_hikey_usb: Driver to support onboard USB gpio hub on Hikey960Yu Chen1-0/+9
The HiKey960 has a fairly complex USB configuration due to it needing to support a USB-C port for host/device mode and multiple USB-A ports in host mode, all using a single USB controller. See schematics here: https://github.com/96boards/documentation/raw/master/consumer/hikey/hikey960/hardware-docs/HiKey960_Schematics.pdf This driver acts as a usb-role-switch intermediary, intercepting the role switch notifications from the tcpm code, and passing them on to the dwc3 core. In doing so, it also controls the onboard hub and power gpios in order to properly route the data lines between the USB-C port and the onboard hub to the USB-A ports.

2020-05-13bus: vexpress-config: Merge vexpress-syscfg into vexpress-configRob Herring1-9/+0
The only thing that vexpress-syscfg does is provide a regmap to vexpress-config bus child devices. There's little reason to have 2 components for this. The current structure with initcall ordering requirements makes turning these components into modules more difficult. So let's start to simplify things and merge vexpress-syscfg into vexpress-config. There's no functional change in this commit and it's still separate components until subsequent commits.

2020-02-22uacce: add uacce driverKenneth Lee1-0/+1
Uacce (Unified/User-space-access-intended Accelerator Framework) targets to provide Shared Virtual Addressing (SVA) between accelerators and processes. So accelerator can access any data structure of the main cpu. This differs from the data sharing between cpu and io device, which share only data content rather than address. Since unified address, hardware and user space of process can share the same virtual address in the communication. Uacce create a chrdev for every registration, the queue is allocated to the process when the chrdev is opened. Then the process can access the hardware resource by interact with the queue file. By mmap the queue file space to user space, the process can directly put requests to the hardware without syscall to the kernel space. The IOMMU core only tracks mm<->device bonds at the moment, because it only needs to handle IOTLB invalidation and PASID table entries. However uacce needs a finer granularity since multiple queues from the same device can be bound to an mm. When the mm exits, all bound queues must be stopped so that the IOMMU can safely clear the PASID table entry and reallocate the PASID. An intermediate struct uacce_mm links uacce devices and queues. Note that an mm may be bound to multiple devices but an uacce_mm structure only ever belongs to a single device, because we don't need anything more complex (if multiple devices are bound to one mm, then we'll create one uacce_mm for each bond). uacce_device --+-- uacce_mm --+-- uacce_queue | '-- uacce_queue | '-- uacce_mm --+-- uacce_queue +-- uacce_queue '-- uacce_queue Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Kenneth Lee <liguozhu@hisilicon.com> Signed-off-by: Zaibo Xu <xuzaibo@huawei.com> Signed-off-by: Zhou Wang <wangzhou1@hisilicon.com> Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org> Signed-off-by: Zhangfei Gao <zhangfei.gao@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

2019-05-02clocksource/drivers/tcb_clksrc: Stop depending on atmel_tclibAlexandre Belloni1-12/+2
atmel_tclib is probed too late in the boot process to be able to use the TCB as the boot clocksource. This is an issue for SoCs without the PIT (sams70, samv70 and samv71 families) as they simply currently can't boot. Get rid of the atmel_tclib dependency and probe everything on our own using the correct device tree binding. This also allows getting rid of ATMEL_TCB_CLKSRC_BLOCK and makes the driver a bit more flexible as the TCB is not hardcoded in the kernel anymore.

2018-05-14misc: IBM Virtual Management Channel Driver (VMC)Bryant G. Ly1-0/+14
This driver is a logical device which provides an interface between the hypervisor and a management partition. This interface is like a message passing interface. This management partition is intended to provide an alternative to HMC-based system management. VMC enables the Management LPAR to provide basic logical partition functions: - Logical Partition Configuration - Boot, start, and stop actions for individual partitions - Display of partition status - Management of virtual Ethernet - Management of virtual Storage - Basic system management This driver is to be used for the POWER Virtual Management Channel Virtual Adapter on the PowerPC platform. It provides a character device which allows for both request/response and async message support through the /dev/ibmvmc node. Signed-off-by: Bryant G.

2017-09-13drivers: misc: ti_dac7512: Remove duplicate driverLukas Wunner1-10/+0
The Texas Instruments DAC7512 has the exact same pinout, programming interface and power-down modes as the Texas Instruments DAC121S101 and Analog Devices AD5320, which are already supported by the IIO driver ad5446.c. Remove the duplicate misc driver. This requires user space to migrate to the standardized IIO sysfs ABI. (In other words, it needs to change a filename.) The IIO driver supports the chip's features more fully, e.g. the ability to power down the output or choose one of the available powerdown modes. There is an oddity with the misc driver in that it initializes the SPI slave to SPI_MODE_0, in contradiction to the datasheet which specifies that data is latched in on the falling edge, implying that SPI_MODE_1 or SPI_MODE_2 must be used. Another oddity is that Kconfig and the MODULE_DESCRIPTION() claim the chip has 16-bit resolution although it actually has 12-bit.
