Paul Cercueil authored
By being a bit smarter about how the SoC version checks are performed, it is possible to have all the code paths that correspond to SoCs disabled in the kernel config automatically marked as dead code by the compiler, and therefore garbage-collected. With this patch, when compiling a kernel that only targets the JZ4760 for instance, the driver is now about 4.5 KiB smaller. Signed-off-by:

The SoC supports a debug clock output of its internal clocks. Depending on the clk_sel input (GPIO_31) clk_mon (GPIO_30) will output either cpu_clk/64 or sys_clk/64. This is very useful for debugging and is missing in the pinmux table. Add it. Signed-off-by:

Convert the ocelot-pinctrl device tree binding to the new YAML format. Additionally to the original binding documentation, add interrupt properties which are optional and already used on several SoCs like SparX-5, Luton, Ocelot and LAN966x but were not documented before.

The commit c8013355 ("ARM: dts: gpio-ranges property is now required") fixed the GPIO probing issues caused by "pinctrl: bcm2835: Change init order for gpio hogs". This changed only the kernel DTS files. Unfortunately it isn't guaranteed that these files are shipped to all users. So implement the necessary backward compatibility for BCM2835 and BCM2711 platform. Fixes: 266423e6 ("pinctrl: bcm2835: Change init order for gpio hogs") Signed-off-by:

Since commit 2ab73c6d ("gpio: Support GPIO controllers without pin-ranges") the device tree nodes of GPIO controller need the gpio-ranges property to handle gpio-hogs. Unfortunately it's impossible to guarantee that every new kernel is shipped with an updated device tree binary. In order to provide backward compatibility with those older DTB, we need a callback within of_gpiochip_add_pin_range() so the relevant platform driver can handle this case.

Nícolas F. R. A. Prado authored
On mt8192, the pinctrl node has pinctrl groups to group pin configurations. Each pinctrl group contains one or more pinmux subnodes to list needed pins and their configurations. By supporting multiple subnodes, we can configure different pin characteristics (driving/pull-up/pull-down/etc.) in a pinctrl group. Update the mt8192 pinctrl dt-binding to add the missing pinctrl group node that wraps the pinmux subnodes and update the example at the end. While at it, also remove the example embedded in the description since it is redundant to the already supplied example at the end. This same change was done for mt8195 in commit 79dcd4e8 ("dt-bindings: pinctrl: mt8195: add wrapping node of pin configurations"). Signed-off-by:
