Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2019-09-16T22:52:38+00:00

Pull ARM SoC driver updates from Arnd Bergmann:
 "This contains driver changes that are tightly connected to SoC
  specific code. Aside from smaller cleanups and bug fixes, here is a
  list of the notable changes.

  New device drivers:

   - The Turris Mox router has a new "moxtet" bus driver for its
     on-board pluggable extension bus. The same platform also gains a
     firmware driver.

   - The Samsung Exynos family gains a new Chipid driver exporting using
     the soc device sysfs interface

   - A similar socinfo driver for Qualcomm Snapdragon chips.

   - A firmware driver for the NXP i.MX DSP IPC protocol using shared
     memory and a mailbox

  Other changes:

   - The i.MX reset controller driver now supports the NXP i.MX8MM chip

   - Amlogic SoC specific drivers gain support for the S905X3 and A311D
     chips

   - A rework of the TI Davinci framebuffer driver to allow important
     cleanups in the platform code

   - A couple of device drivers for removed ARM SoC platforms are
     removed. Most of the removals were picked up by other maintainers,
     this contains whatever was left"

soc: fsl: dpio: remove explicit device_link_remove

2019-08-15T23:20:20+00:00

Starting with commit 72175d4ea4c4 ("driver core: Make driver core
own stateful device links") stateful device links are owned by the
driver core and should not be explicitly removed on device unbind.
Delete all device_link_remove appearances from the dpio driver.

soc/fsl/qbman: Update device tree with reserved memory

2019-08-15T21:42:00+00:00

When using the reserved memory node in the device tree there are
two options - dynamic or static. If a dynamic allocation was
selected (where the kernel selects the address for the allocation)
convert it to a static allocation by inserting the reg property.
This will ensure the same memory is reused after a kexec()

soc/fsl/qbman: Fixup qman_shutdown_fq()

2019-08-15T21:41:56+00:00

When shutting down a FQ on a dedicated channel only the
SW portal associated with that channel can dequeue from it.
Make sure the correct portal is use.

The drain_mr_fqni() function may be called fron uninterruptable
context so convert the msleep() to an mdelay().  Also ensure that
the valid bit is updated while polling.

soc/fsl/qbman: Cleanup QMan queues if device was already initialized

2019-08-15T21:41:47+00:00

If the QMan device was previously initialized make sure all the
frame queues are out of service once all the portals are probed.
This handles the case where the kernel is restarted without the
SoC being reset (kexec for example)

soc/fsl/qbman: Cleanup buffer pools if BMan was initialized prior to bootup

2019-08-15T21:41:42+00:00

Clean the BMan buffer pools if the device had been initialized
previously.  This will ensure a consistent state if the kernel
was soft restarted (kexec for example)

soc/fsl/qbman: Rework QBMan private memory setup

2019-08-15T21:41:32+00:00

Rework QBMan private memory setup so that the areas are not
zeroed if the device was previously initialized

If the QMan private memory was already initialized skip the PFDR
initialization.
