pinctrl: nomadik: factor in platform data container · 8f18bcfc

由 Linus Walleij 提交于 3月 21, 2014

The old platform data struct is just a leftover from the times
when the driver was not probed exclusively from the device tree.
Factor this into the general state container and simplify the
probe path.

pinctrl: nomadik: rename secondary to latent · 194e15ba

由 Linus Walleij 提交于 3月 21, 2014

The "secondary irq" in the nomadik pin control driver is actually
not secondary (as in: can occur any time alongside the ordinary
irq), it is a latent IRQ. It is an IRQ that has occurred when
the system was in sleep state and has been cached in a special
register flagged from the low power management unit (PRCM).

pinctrl: coh901: move irq line locking to resource callbacks · 8c1d50a6

由 Linus Walleij 提交于 3月 14, 2014

This switches the COH901 GPIO driver over to using the
.request_resources() and .release_resources() callbacks from
the irqchip vtable and separate the calls from the .enable()
and .disable() callbacks as the latter cannot really say no
to a request, whereas the resource callbacks can.

gpio: switch drivers to use new callback · 57ef0428

由 Linus Walleij 提交于 3月 14, 2014

This switches all GPIO and pin control drivers with irqchips
that were using .startup() and .shutdown() callbacks to lock
GPIO lines for IRQ usage over to using the .request_resources()
and .release_resources() callbacks just introduced into the
irqchip vtable.

pinctrl: tegra: add some missing Tegra114 entries · 43f23a06

由 Stephen Warren 提交于 3月 13, 2014

Add some missing pin and drive group definitions to the driver. These
are all defined in the TRM, but missing from the driver for some reason.

Fix a couple of mistakes in the drive group definitions.

Much of the diff to tegra114_groups[] is an indentation change due to one
of the new group names being long. git diff/show -w will highlight this.

A couple of pairs of pin group names were swapped in the table. This
caused the wrong register to be programmed. Luckily, this had little
effect, if any, since the swapped pins were likely to be programmed
identically.

Commit 051a58b4
"pinctrl: msm: Simplify msm_config_reg() and callers"
removed the local "reg" variable in the msm_config_reg()
function, but the earlier
commit ed118a5f
"pinctrl-msm: Support output-{high,low} configuration"
introduced a new switchclause using it.

Fix this up by removing the offending register assignment.

This patch fixes an error check while using of_irq_to_resource.
of_irq_to_resource returns non-zero interrupt number on success and zero
on error. The driver was using error check is wrong way.

Without this patch the driver will configure interrupt zero if there is
no interrupt specified in the node.

Fix Tegra30/114/124 pinmux drivers consistency issues.
* Sort all lists of the same object type (e.g. #defines for pins, and
  the array that defines their names) in the same order.
* Whitespace fixes.
* Consistency in layout between the 3 drivers.

These driver files were also auto-generated, which should allow us to
make e.g. the U-Boot drivers completely consistent with the kernel in
the future:-)

pinctrl: tegra: dynamically calculate function list of groups · ce436254

由 Stephen Warren 提交于 3月 07, 2014

The per-SoC data structures for Tegra pinctrl stored some information
in a redundant way. Specifically, the list of groups that each function
could be muxed onto was stored once explicitly, and also as part of the
definition of each group. Eliminate this redundancy, and calculate each
function's list of valid groups at pinctrl probe time. This removes
thousands of lines of code from the pinctrl driver and ~16K from the
vmlinux binary size, and adds only about 500uS to the boot process (on
Tegra30; newer SoCs will likely be faster still).

pinctrl: st: Enhance the controller to manage unavailable registers · 4e6a609f

由 Giuseppe Cavallaro 提交于 3月 12, 2014

This patch adds a new logic inside the st pinctrl to manage
an unsupported scenario: some sysconfig are not available!

This is the case of STiH407 where, although documented, the
following registers from SYSCFG_FLASH have been removed from the SoC.

SYSTEM_CONFIG3040
   Output Enable pad control for all PIO Alternate Functions
and
SYSTEM_ CONFIG3050
   Pull Up pad control for all PIO Alternate Functions

Without managing this condition an imprecise external abort
will be detect.

To do this the patch also reviews the st_parse_syscfgs
and other routines to manipulate the registers only if
actually available.
In any case, for example the st_parse_syscfgs detected
an error condition but no action was made in the
st_pctl_probe_dt.
