On SAM9X60, slewrate should be enabled on pins with a switching frequency
below 50Mhz. Since most of our pins do not exceed this value, we enable
slewrate by default. Pins with a switching value that exceeds 50Mhz will
have to explicitly disable slewrate.
This patch changes the ABI. However, the slewrate macros are only used
by SAM9X60 and, at this moment, there are no device-tree files available
for this platform.

pinctrl: sh-pfc: Updates for v5.5 (take two)
- Add support for the new R-Car M3-W+ (r8a77961) SoC,
- Small fixes and cleanups.

The definitions for bit field [19:18] of the Peripheral Function Select
Register 3 were accidentally copied from bit field [20], leading to
duplicates for the TCLK1_B function, and missing TCLK0, CAN_CLK_B, and
ET0_ETXD4 functions.
Fix this by adding the missing GPIO_FN_CAN_CLK_B and GPIO_FN_ET0_ETXD4
enum values, and correcting the functions.

Add support for the Pin Function Controller in the R-Car M3-W+

R-Car M3-W+ is pin compatible with R-Car M3-W (R8A77960), which allows
for both SoCs to share a driver.

Rename CONFIG_PINCTRL_PFC_R8A7796 for R-Car M3-W (R8A77960) to
CONFIG_PINCTRL_PFC_R8A77960, to avoid confusion with R-Car M3-W+
(R8A77961), which will use CONFIG_PINCTRL_PFC_R8A77961.
Extend the dependency of CONFIG_PINCTRL_PFC_R8A77960 from
CONFIG_ARCH_R8A7796 to CONFIG_ARCH_R8A77960, to relax dependencies for a
future rename of the SoC configuration symbol.
Rename r8a7796_pinmux_info to r8a77960_pinmux_info, as it contains an
r8a77960-based name.

As platform_get_irq() now prints an error when the interrupt does not
exist, counting interrupts by looping until failure causes the printing
of scary messages like:
sh-pfc e6060000.pin-controller: IRQ index 0 not found
Fix this by using the platform_irq_count() helper instead.

The latent IRQs are IRQs that have occurred when the system
was down in deep sleep and the GPIO block was powered off.
The PRCMU (power reset and control unit) knows which GPIO
line offset fired an IRQ to wake the system up (if so
desired) and this second IRQ was used to replay the action
when the system came back online after suspend().
This is now known to be the wrong approach to solve this
problem: in a patch series Lina Iyer has suggested to
instead make it possible to model the IRQs as hierarchical
with double parents.
Also the current device trees do not contain the right
information to make this code work, the latent IRQ is not
specified nowadays giving noise like this in the console:
[ 0.612168] gpio 8012e000.gpio: IRQ index 1 not found
[ 0.622523] gpio 8012e080.gpio: IRQ index 1 not found
Let's delete the latent IRQ code and reimplement it properly
when we need it.

For chained irqchips this is a pretty straight-forward

deal with that. Keep the exit path where the gpio_chip
is added no matter what the status of the irq is.

When populating the pinctrl mapping table entries for a device, the
'dev_name' field for each entry is initialised to point directly at the
string returned by 'dev_name()' for the device and subsequently used by
'create_pinctrl()' when looking up the mappings for the device being
probed.
This is unreliable in the presence of calls to 'dev_set_name()', which may
reallocate the device name string leaving the pinctrl mappings with a
dangling reference. This then leads to a use-after-free every time the
name is dereferenced by a device probe:

According to the R-Car Gen3 Hardware Manual Errata for Rev 1.00 of Aug
24, 2018, the SEL_SIMCARD_{0,1} definition was to be deleted. However,
this errata merely fixed an accidental double definition in the Hardware

revisions of the manual (Rev. 1.50 and Rev. 2.00).
Hence revert the commit to recover the definition.

This reverts commit e87882eb9be10b2b9e28156922c2a47d877f5db4.
According to the R-Car Gen3 Hardware Manual Errata for Rev 1.00 of Aug
24, 2018, the SEL_SSI2_{0,1} definition was to be deleted. However,
this errata merely fixed an accidental double definition in the Hardware
User's Manual Rev. 1.00. The real definition is still present in later
revisions of the manual (Rev. 1.50 and Rev. 2.00).
Hence revert the commit to recover the definition.
Based on a patch in the BSP by Takeshi Kihara
<takeshi.kihara.df@renesas.com>.

The Hardware Manual Errata for Rev. 1.50 of April 10, 2019 renamed IPSR2
register bit[23:20] value H'3 and register bit[27:24] value H'3 from
AVB_AVTP_MATCH_A resp. AVB_AVTP_CAPTURE_A to AVB_AVTP_MATCH resp.
AVB_AVTP_CAPTURE.
Update the R-Car E3 pin control driver to reflect this.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.
For chained irqchips this is a pretty straight-forward
conversion.

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.4 kernel cycle:
Core changes:
- Fix errors in example code in the documentation.
New drivers:
- Add support for JZ4760, JZ4760B, X1000, X1000E and X1500 to the
Ingenic driver.
- Support Cirrus Logic Madera CS47L92 and CS47L15.
- Support Allwinner Sunxi V3S.
- Support Aspeed 2600 BMC.
- Support Qualcomm SC7180.
- Support Marvell MVEBU CS115.
Driver improvements:
- Clean up a few drivers to use the devm_platform_ioremap_resource()
helper.
- Pass the irqchip when registering the gpio_chip in some pin
controllers that are also GPIO controllers.
- Support suspend/resume in the Tegra driver.
- Support pull-up on the Broadcom BCM2711.
- The Intel driver can now request locked pads.
- Fix the UFS reset pin in the Qualcomm SDM845 driver"
