This series adds dual parallel mode support for Zynq Ultrascale+
MPSoC GQSPI controller driver.
What is dual parallel mode?
---
ZynqMP GQSPI controller supports Dual Parallel mode with following
functionalities:
1) Supporting two SPI flash memories operating in parallel. 8
This patch adds support for dual parallel configuration by:
- Adding required parameters like isparallel and shift to spi_nor structure.
- Initializing all added parameters in spi_nor_scan()
- Updating read_sr() and read_fsr() for getting status of both flashes
- Increasing page_size, sector_size,
This patch adds struct spi_device instacne to the spi_nor structure

Being careless, judge the return value of snd_soc_card_jack_new
is opposite, so it should be fixed.

The issue was that whenever an itimer expired, many threads ended up

When running a database workload on a 16 socket machine, there were

The fastpath_timer_check() contains logic to check for if any timers
are set by checking if !task_cputime_zero(). Similarly, we can do this
before calling check_thread_timers(). In the case where there
are only process-wide timers, this will skip all the computations for
the per-thread timers when
In fastpath_timer_check(), the task_cputime() function is always
called to compute the utime and stime values. However, this is not
necessary if there are no per-thread timers to check for. This patch
modifies the code such that we compute the task_cputime values only
when there are per-thread time

The Kconfig currently controlling compilation of this code is:
menuconfig MODULES
bool "Enable loadable module support"
...meaning that it currently is not being built as a module by anyone.
No surprise here, since modular support being a module would be an

This patch and patch 1 seem OK to me, although I'll withhold any ack
until the DT binding design discussion with Rob has been resolved. I
haven't looked at the OF graph bindings he mentioned so have n
have used te mmc-uh tree from next-20150825 for today.
