FPGA Manager fixes for 5.3

A single fix for the altera-ps-spi driver that fixes the behavior when
the driver receives -EPROBE_DEFER when trying to obtain a GPIO desc.

fpga: altera-ps-spi: Fix getting of optional confd gpio

2019-08-19T00:40:02+00:00

Currently the driver does not handle EPROBE_DEFER for the confd gpio.
Use devm_gpiod_get_optional() instead of devm_gpiod_get() and return
error codes from altera_ps_probe().

fpga-manager: altera-ps-spi: Fix build error

2019-07-24T09:29:41+00:00

If BITREVERSE is m and FPGA_MGR_ALTERA_PS_SPI is y,
build fails:

drivers/fpga/altera-ps-spi.o: In function `altera_ps_write':
altera-ps-spi.c:(.text+0x4ec): undefined reference to `byte_rev_table'

Select BITREVERSE to fix this.

mm: add account_locked_vm utility function

2019-07-17T02:23:25+00:00

locked_vm accounting is done roughly the same way in five places, so
unify them in a helper.

Include the helper's caller in the debug print to distinguish between
callsites.

Error codes stay the same, so user-visible behavior does too.  The one
exception is that the -EPERM case in tce_account_locked_vm is removed
because Alexey has never seen it triggered.

Merge tag 'driver-core-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2019-07-12T19:24:03+00:00

Pull driver core and debugfs updates from Greg KH:
 "Here is the "big" driver core and debugfs changes for 5.3-rc1

  It's a lot of different patches, all across the tree due to some api
  changes and lots of debugfs cleanups.

  Other than the debugfs cleanups, in this set of changes we have:

   - bus iteration function cleanups

   - scripts/get_abi.pl tool to display and parse Documentation/ABI
     entries in a simple way

   - cleanups to Documenatation/ABI/ entries to make them parse easier
     due to typos and other minor things

   - default_attrs use for some ktype users

   - driver model documentation file conversions to .rst

   - compressed firmware file loading

   - deferred probe fixes

  All of these have been in linux-next for a while, with a bunch of
  merge issues that Stephen has been patient with me for"

fpga: dfl: fme: align PR buffer size per PR datawidth

2019-07-03T17:58:59+00:00

Current driver checks if input bitstream file size is aligned or
not per PR data width (default 32bits). It requires one additional
step for end user when they generate the bitstream file, padding
extra zeros to bitstream file to align its size per PR data width,
but they don't have to as hardware will drop extra padding bytes
automatically.

In order to simplify the user steps, this patch aligns PR buffer
size per PR data width in driver, to allow user to pass unaligned
size bitstream files to driver.

fpga: dfl: fme: remove copy_to_user() in ioctl for PR

2019-07-03T17:58:58+00:00

This patch removes copy_to_user() code in partial reconfiguration
ioctl, as it's useless as user never needs to read the data
structure after ioctl.

fpga: dfl-fme-mgr: fix FME_PR_INTFC_ID register address.

2019-07-03T17:58:58+00:00

FME_PR_INTFC_ID is used as compat_id for fpga manager and region,
but high 64 bits and low 64 bits of the compat_id are swapped by
mistake. This patch fixes this problem by fixing register address.

drivers: Add generic helper to match by of_node

2019-06-24T03:22:31+00:00

Add a helper to match device by the of_node. This will be later used
to provide wrappers to the device iterators for {bus/class/driver}_find_device().
Convert other users to reuse this new helper.
