very new Qualcomm and Intel chips.

New drivers:

- Intel Jasper Lake support.

- NXP Freescale i.MX8DXL support.

- Qualcomm SM8250 support.

- Renesas R8A7742 SH-PFC support.

Driver improvements:

- Severe cleanup and modernization of the MCP23s08 driver.

pinctrl: qcom: Add affinity callbacks to msmgpio IRQ chip

2020-05-12T12:29:29+00:00

Wakeup capable GPIO IRQs routed via PDC are not being migrated when a CPU
is hotplugged. Add affinity callbacks to msmgpio IRQ chip to update the
affinity of wakeup capable IRQs.

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.7 kernel cycle.

There are no core changes this time, only driver developments:

- New driver for the Dialog Semiconductor DA9062 Power Management
Integrated Circuit (PMIC).

- Renesas SH-PFC has improved consistency, with group and register
checks in the configuration checker.

- New subdriver for the Qualcomm IPQ6018.

- Add the RGMII pin control functionality to Qualcomm IPQ8064.

- Performance and code quality cleanups in the Mediatek driver.

- Improve the Broadcom BCM2835 support to cover all the GPIOs that
exist in it.

- The Allwinner/Sunxi driver properly masks non-wakeup IRQs on
suspend.

- Add some missing groups and functions to the Ingenic driver.

- Convert some of the Freescale device tree bindings to use the new
and all improved JSON YAML markup.

- Refactorings and support for the SFIO/GPIO in the Tegra194 SoC
driver.

- Support high impedance mode in the Spreadtrum/Unisoc driver"

pinctrl: qcom: use scm_call to route GPIO irq to Apps

2020-03-27T23:36:18+00:00

For IPQ806x targets, TZ protects the registers that are used to
configure the routing of interrupts to a target processor.
To resolve this, this patch uses scm call to route GPIO interrupts
to application processor. Also the scm call interface is changed.

pinctrl: qcom: Assign irq_eoi conditionally

2020-03-09T15:31:34+00:00

The hierarchical parts of MSM pinctrl/GPIO is only
used when the device tree has a "wakeup-parent" as
a phandle, but the .irq_eoi is anyway assigned leading
to semantic problems on elder Qualcomm chipsets.

When the drivers/mfd/qcom-pm8xxx.c driver calls
chained_irq_exit() that call will in turn call chip->irq_eoi()
which is set to irq_chip_eoi_parent() by default on a
hierachical IRQ chip, and the parent is pinctrl-msm.c
so that will in turn unconditionally call
irq_chip_eoi_parent() again, but its parent is invalid
so we get the following crash:

 Unnable to handle kernel NULL pointer dereference at
 virtual address 00000010
 pgd = (ptrval)
 [00000010] *pgd=00000000
 Internal error: Oops: 5 [#1] PREEMPT SMP ARM
 (...)
 PC is at irq_chip_eoi_parent+0x4/0x10
 LR is at pm8xxx_irq_handler+0x1b4/0x2d8

If we solve this crash by avoiding to call up to
irq_chip_eoi_parent(), the machine will hang and get
reset by the watchdog, because of semantic issues,
probably inside irq_chip.

As a solution, just assign the .irq_eoi conditionally if
we are actually using a wakeup parent.

pinctrl: qcom: ssbi-gpio: Fix fwspec parsing bug

2020-03-09T12:52:37+00:00

We are parsing SSBI gpios as fourcell fwspecs but they are
twocell. Probably a simple copy-and-paste bug.

Tested on the APQ8060 DragonBoard and after this ethernet
and MMC card detection works again.
