All Samsung pinctrl drivers select common part - PINCTRL_SAMSUNG which uses
both OF and GPIOLIB inside. However only Exynos drivers depend on these,
therefore after enabling COMPILE_TEST, on x86_64 build of S3C64xx driver
failed:
drivers/pinctrl/samsung/pinctrl-samsung.c: In function ‘samsung_gpiolib_register’:
drivers/pinctrl/samsung/pinctrl-samsung.c:969:5: error: ‘struct gpio_chip’ has no member named ‘of_node’
gc->of_node = bank->of_node;
^
Rework the dependencies so all Samsung drivers and common
PINCTRL_SAMSUNG part depend on OF_GPIO (which is default yes if GPIOLIB
and OF are enabled).

The config options toggle Samsung Exynos SoCs pinctrl drivers, not the
driver data. Clarify this in the option title/name and also make it
consistent with other Samsung entries. No functional change.

The Samsung pinctrl drivers require only GPIOLIB and OF for building.
The drivers should be buildable on all architectures so enable
COMPILE_TEST.

Despite using the same compatible values ("r8a7795"-based) because of
historical reasons, R-Car H3 ES1.x (R8A77950) and R-Car H3 ES2.0+
(R8A77951) are really different SoCs, with different part numbers, and
with different Pin Function Controller blocks.
Reflect this in the pinctrl configuration, by replacing the existing
CONFIG_PINCTRL_PFC_R8A7795 symbol by two new config symbols:
CONFIG_PINCTRL_PFC_R8A77950 and CONFIG_PINCTRL_PFC_R8A77951. The latter
are selected automatically, depending on the soon-to-be-introduced
corresponding SoC-specific config options, and on the current common
config option, to relax dependencies.
Rename the individual pin control driver source files from
pfc-r8a7795-es1.c to pfc-r8a77950.c, and from pfc-r8a7795.c to
pfc-r8a77951.c, and make them truly independent.
As both SoCs share the same compatible value, special care must be taken
to match them to the correct pin control driver, if support for it is
included in the running kernel.
This will allow making support for early R-Car H3 revisions optional,
the largest share of which is taken by the pin control driver.

pinmux_func_gpios[] contains a hole due to the missing function GPIO
definition for the "CTX0&CTX1" signal, which is the logical "AND" of the
first two CAN outputs.
A closer look reveals other issues:
- Some functionality is available on alternative pins, but the
PINMUX_DATA() entries is using the wrong marks,
- Several configurations are missing.
Fix this by:
- Renaming CTX0CTX1CTX2_MARK, CRX0CRX1_PJ22_MARK, and
CRX0CRX1CRX2_PJ20_MARK to CTX0_CTX1_CTX2_MARK, CRX0_CRX1_PJ22_MARK,
resp. CRX0_CRX1_CRX2_PJ20_MARK for consistency with the
corresponding enum IDs,
- Adding all missing enum IDs and marks,
- Use the right (*_PJ2x) variants for alternative pins,
- Adding all missing configurations to pinmux_data[],
- Adding all missing function GPIO definitions to pinmux_func_gpios[].

pinmux_func_gpios[] contains a hole due to the missing function GPIO
definition for the "CTX0&CTX1" signal, which is the logical "AND" of the
two CAN outputs.
Fix this by:
- Renaming CRX0_CRX1_MARK to CTX0_CTX1_MARK, as PJ2MD[2:0]=010
configures the combined "CTX0&CTX1" output signal,
- Renaming CRX0X1_MARK to CRX0_CRX1_MARK, as PJ3MD[1:0]=10 configures
the shared "CRX0/CRX1" input signal, which is fed to both CAN
inputs,
- Adding the missing function GPIO definition for "CTX0&CTX1" to
pinmux_func_gpios[],
- Moving all CAN enums next to each other.

[6] Section 32.2.30 (3) Port J Control Register 0 (PJCR0).
Note that the last 2 disagree about PJ2MD[2:0], which is probably the
root cause of this bug. But considering [4], "CTx0&CTx1" in [5] must
be correct, and "CRx0&CRx1" in [6] must be wrong.

R-Car Gen3 Hardware Manual Errata for Rev. 2.00 of October 24, 2019
changed the configuration bits for drive and bias control for the
DU_DOTCLKIN3 pin on R-Car M3-N, to match the same pin on R-Car H3.
Update the driver to reflect this.
After this, the handling of drive and bias control for the various
DU_DOTCLKINx pins is consistent across all of the R-Car H3, M3-W,
M3-W+, and M3-N SoCs.

If there are no function GPIOs, sh_pfc_register_gpiochip() returns early
with a success indicator. This is fragile, as new code may be added
after the #ifdef block, which won't be executed in case of early return.
Invert the logic, so the code always continues until the end of the
function on success.

GPIOH_5 and GPIOH_6 can have two Ethernet related functions:
- GPIOH_5 can be ETH_TXD1 or ETH_RXD3
- GPIOH_6 can be ETH_TXD0 or ETH_RXD2
Add the bits for eth_rxd3_h and eth_rxd2_h so the ETH_RXD function can
be disabled when using the ETH_TXD function of GPIOH_{5,6}. No problem
was observed so far, but in theory this could lead to two different
signals being routed to the same pad (which could break Ethernet).
These settings were found in the public "Amlogic Ethernet controller
user guide":

platform_irq_count() is the more generic way (independent of
device trees) to determine the count of available interrupts. So
use this instead.
As platform_irq_count() might return an error code (which
of_irq_count doesn't) some additional handling is necessary.

Currently only the drivers/pinctrl/devicetree.c code allows registering
pinctrl-mappings which may later be unregistered, all other mappings
are assumed to be permanent.
Non-dt platforms may also want to register pinctrl mappings from code which
is build as a module, which requires being able to unregister the mapping
when the module is unloaded to avoid dangling pointers.
To allow unregistering the mappings the devicetree code uses 2 internal
functions: pinctrl_register_map and pinctrl_unregister_map.
pinctrl_register_map allows the devicetree code to tell the core to
not memdup the mappings as it retains ownership of them and
pinctrl_unregister_map does the unregistering, note this only works
when the mappings where not memdupped.
The only code relying on the memdup/shallow-copy done by
pinctrl_register_mappings is arch/arm/mach-u300/core.c this commit
replaces the __initdata with const, so that the shallow-copy is no
longer necessary.
After that we can get rid of the internal pinctrl_unregister_map function
and just use pinctrl_register_mappings directly everywhere.
This commit also renames pinctrl_unregister_map to
pinctrl_unregister_mappings so that its naming matches its
pinctrl_register_mappings counter-part and exports it.
Together these 2 changes will allow non-dt platform code to
register pinctrl-mappings from modules without breaking things on
module unload (as they can now unregister the mapping on unload).

Rather than always using handle_simple_irq() as the gpio_irq_chip
handler, set a more appropriate handler based on the IRQ trigger type
requested.
This is important for level triggered interrupts which need to be

on sc7180 we have cases where multiple functions from the same
qup instance share the same pin. This is true for qup02/04/11 and qup13.
Add new function names to distinguish which qup function to use.
The device tree files for this platform haven't landed in mainline yet,
so there aren't any users upstream who should break with this change
in function names, however, anyone using the devicetree files that were
posted on the lists and using these specific function names will need
to update their changes.

3. BMC EHCI to PHY
4. PCIe EHCI to PHY
Port B support 3 modes:
1. USB1.1 HID controller
2. USB2.0 Device controller
3. BMC EHCI port2

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.6 kernel cycle.
This is a pretty calm cycle so far, nothing special going on really.
Some more changes will come in from the irqchip and pin control trees.
I also deleted an orphan include file for FMC that was dangling since
subsystem was removed.
Core changes:
- Document the usecases for the kernelspace vs userspace handling of
GPIOs.
- Handle MSI (message signalled interrupts) properly in the core
hierarchical irqdomain code.
- Fix a rare race condition while initializing the descriptor array.
New drivers:
- Xylon LogiCVC GPIO driver.
- WDC934x GPIO controller driver.
Driver improvements:
- Implemented suspend/resume in the Tegra driver.
- MPC8xx edge detection fixup.
- Properly convert ThunderX to use hierarchical irqdomain with
GPIOLIB_IRQCHIP on top of the revert of the previous buggy
switchover. This time it works (hopefully).
Misc:
- Drop a FMC remnant file <linux/ipmi-fru.h>
- A slew of fixes"

Some gpio's parent irqdomain may not use the struct irq_fwspec as
argument, such as msi irqdomain. So rename the callback
populate_parent_fwspec() to populate_parent_alloc_arg() and make it
allocate and populate the specific struct which is needed by the
parent irqdomain.
