Copy the device nodes from Koelsch reference into the Koeslch device tree file. This will allow us to use a single DTS file regarless of kernel configuration. In case of legacy C board code the device nodes may or may not be used, but in the multiplatform case all the DT device nodes are used. Signed-off-by:

The koelsch board uses has an SH ethernet controller which uses a Micrel phy. Select MICREL_PHY for koelsch if SH_ETH is enabled to make use of the Micrel-specific phy driver rather than relying on the generic phy driver. Signed-off-by: -

This is a commit from the for-next branch of Linus Walleij's pin control tre git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git It is the oldest commit in that branch that provides the dependencies needed for SoC changes to the usage of sh-pfc.

When CONFIG_COMMON_CLOCK is enabled, call rcar_gen2_clocks_init() in the timer init function to initialize the common clock framework before initializing the clock sources. This will take care of clock initialization when the r8a779[01] boards will be switched to multiplatform kernels. Signed-off-by:

The PCI sub-system is not enabled by default on ARM and on certain Renesas devices the build does not select it. This means that there are configurations that do not allow the AHB-PCI bridge used for the USB sub-systems to be built. For the R8A7790, R8A7791 and EMEV-2 select MIGHT_HAVE_PCI to allow the PCI drivers to be built. Also select MIGHT_HAVE_PCI for the multi-config where there may be many Reneasas devices selected.

The break timer accesses hardware registers and thus requires the port to be enabled. It currently ensures this by enabling the port at the beginning of the timer handler, and disabling it at the end. However, the enable/disable operations call the runtime PM sync functions, which are not allowed in atomic context. The current situation is thus broken. This change relies on non-atomic code to enable/disable the port. The break timer will only be started from the IRQ handler, which already runs with the port enabled. We just need to ensure that the port won't be disabled with the timer running, and that's easily done by just cancelling the timer in the port disable function. Signed-off-by:

MSTP clocks are gate clocks controlled through a register that handles up to 32 clocks. The register is often sparsely populated. Those clocks are found on Renesas ARM SoCs. Signed-off-by:

DIV6 clocks are divider gate clocks controlled through a single register. The divider is expressed on 6 bits, hence the name, and can take values from 1/1 to 1/64. Those clocks are found on Renesas ARM SoCs. Signed-off-by:

The R-Car Gen2 SoCs (R8A7790 and R8A7791) have several clocks that are too custom to be supported in a generic driver. Those clocks can be divided in two categories: - Fixed rate clocks with multiplier and divisor set according to boot mode configuration - Custom divider clocks with SoC-specific divider values This driver supports both.

On non-DT platforms IRQ controllers associated with the GPIOs have a fixed IRQ base value known at compile time. The sh-pfc driver translates GPIO number to IRQ numbers using a hardcoded table. This mechanism breaks on DT platforms, as the IRQ base values are dynamic in that case. Fix this by specifying IRQs associated with GPIOs in IRQ resources, populated automatically from the device tree. When IRQ resources are specified the driver requires one IRQ resource per GPIO able to generate an interrupt, and uses the translation table to compute the IRQ resource offset instead of the IRQ number.

ops->pin_config_get() is only used in one specific path that will only be taken for generic pinconf drivers (ops->is_generic == true) when dumping the pinconf by using debugfs. By removing the check in pinconf_check_ops(), let's stop pressuring people to write a pin_config_get() function that will never be used and so will probably never be tested. Removing the check in pinconf_pins_show() allows driver to not implement pin_config_get() but still get a dump of the pinconf in debugfs by implementing pin_config_dbg_show(). Finally, not implementing pin_config_get() now results in returning -ENOTSUPP instead of -EINVAL. While this doesn't have any real impact for now, this feels more right. Signed-off-by:
