310cdfa009 pinctrl-sx150x: Move some code out of sx150x_init_hw
Move the code configuring explicit IRQ acking into a standalone function
to declutter sx150x_init_hw a bit and make that code somewhat less
repetitious.

465e42180c pinctrl: qcom: Add msm8994 pinctrl driver
Initial pinctrl driver for QCOM msm8994 platforms.

In order to continue the initial board support for QCOM msm8994/msm8992
presented in patches from Jeremy McNicoll <jeremymc@redhat.com>, let's put
a proper pinctrl driver in place.

Currently, the DT for these platforms uses the msm8x74 pinctrl driver to
enable basic UART.  Beyond the first few pins the rest are different enough
to justify it's own driver.

Note: This driver is also used by QCOM's msm8992 platform as it's TLM block
is the same.

- Initial formatting and style was taken from the msm8x74 pinctrl driver
  added by Björn Andersson <bjorn.andersson@linaro.org>
- Data was then adjusted per QCOM MSM8994v2 documentation for Top Level
  Multiplexing
- Bindings documentation was based on qcom,msm8996-pinctrl.txt by
  Joonwoo Park <joonwoop@codeaurora.org> and then modified for msm8994
  content

0c8c6ba00c pinctrl: sunxi: make bool drivers explicitly non-modular
None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.  All
drivers get essentially the same change, so they are handled in batch.

Changes are (1) use builtin_platform_driver, (2) use init.h header
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We do delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

b83bd893f3 pinctrl: bcm2835: reduce GPPUD set-up time
Since the BCM2835 datasheet doesn't exactly specify the set-up time for
the GPIO Pull-up/down Clock Registers there was an assumption of 150 cycles
at a clock rate of 1 MHz. During a discussion [1] in the Raspberry Pi forum
it turns out that clock rate refers to the VPU which has a rate of 250 MHz.
So we can reduce the delay to a sensible value and update the comment above.

I tested this optimization with a Raspberry Pi B and a multimeter.

ecdd1b890d Merge branch 'ib-sx150x' into devel 2016-10-24 16:30:55 +02:00

9e80f9064e pinctrl: Add SX150X GPIO Extender Pinctrl Driver
Since the I2C sx150x GPIO expander driver uses platform_data to manage
the pins configurations, rewrite the driver as a pinctrl driver using
pinconf to get/set pin configurations from DT or debugfs.

The pinctrl driver is functionnally equivalent as the gpio-only driver
and can use DT for pinconf. The platform_data confirmation is dropped.

This patchset removed the gpio-only driver and selects the Pinctrl driver
config instead. This patchset also migrates the gpio dt-bindings to pinctrl
and add the pinctrl optional properties.

The driver was tested with a SX1509 device on a BeagleBone black with
interrupt support and on an X86_64 machine over an I2C to USB converter.

This is a fixed version that builds and runs on non-OF platforms and on
arm based OF. The GPIO version is removed and the bindings are also moved
to the pinctrl bindings.

Changes since v2
 - rebased on v4.9-rc1
 - removed MODULE_DEVICE_TABLE as in upstream bb411e771b
   ("gpio: sx150x: fix implicit assumption module.h is present")

Changes since v1
 - Fix Kconfig descriptions on pinctrl and gpio
 - Fix Kconfig dependency
 - Remove oscio support for non-789 devices
 - correct typo in dt bindings
 - remove probe reset for non-789 devices

Changes since RFC
 - Put #ifdef CONFIG_OF/CONFIG_OF_GPIO to remove OF code for non-of platforms
 - No more rely on OF_GPIO config
 - Moved and enhanced bindings to pinctrl bindings
 - Removed gpio-sx150x.c
 - Temporary select PINCTRL_SX150X when GPIO_SX150X
 - Temporary mark GPIO_SX150X as deprecated

Pull SCSI target fixes from Nicholas Bellinger:
 "Here are the outstanding target-pending fixes for v4.9-rc2.

  This includes:

   - Fix v4.1.y+ reference leak regression with concurrent TMR
     ABORT_TASK + session shutdown. (Vaibhav Tandon)

   - Enable tcm_fc w/ SCF_USE_CPUID to avoid host exchange timeouts
     (Hannes)

   - target/user error sense handling fixes. (Andy + MNC + HCH)

   - Fix iscsi-target NOP_OUT error path iscsi_cmd descriptor leak
     (Varun)

   - Two EXTENDED_COPY SCSI status fixes for ESX VAAI (Dinesh Israni +
     Nixon Vincent)

   - Revert a v4.8 residual overflow change, that breaks sg_inq with
     small allocation lengths.

  There are a number of folks stress testing the v4.1.y regression fix
  in their environments, and more folks doing iser-target I/O stress
  testing atop recent v4.x.y code.

  There is also one v4.2.y+ RCU conversion regression related to
  explicit NodeACL configfs changes, that is still being tracked down"

Apparently trying to poke a disabled or non-existent APIC
leads to a box that doesn't even boot. Let's not do that.

No real clue if this is the right fix, but at least my
P3 machine boots again.
