pinctrl: renesas: Further minimize R8A77965 M3-N PFC tables

2026-08-02T20:15:37Z

Reduce the PFC tables further by gating DRIF, MLB, TMU, TPU and SATA behind PINCTRL_PFC_FULL, none of which are currently supported by U-Boot. This helps reduce the size of the bootloader in 4 kiB range. Signed-off-by: Marek Vasut

arm64: a37xx: pinctrl: fix info->dev used but never set

2026-07-30T19:04:16Z

A bunch of code calls info->dev, mostly dev_* messages and devm_kzalloc. The former can be passed a NULL device and _dev_printk handles this just fine. The latter ignores the dev argument whenever !CONFIG_IS_ENABLED(DEVRES) which was true in most cases until we made CONFIG_DEVRES mandatory for U-Boot proper in commit 217cf656e249 ("dm: core: Default to using DEVRES outside of xPL"). Failing to set info->dev before it's used by devm_kzalloc results in crashes, therefore let's set info->dev before it can be used.

pinctrl: single: parse gpio-range as a raw array (O(N^2) -> O(N))

2026-07-28T18:30:55Z

single_add_gpio_func() calls ofnode_parse_phandle_with_args() once per gpio-range entry. With a flat device tree, every call re-iterates the property from index 0 and, because cellname is set, performs an fdt_node_offset_by_phandle() (a full-FDT scan) at every step. The total cost is therefore quadratic in the number of entries and proportional to the size of the device tree. The impact depends on when the pinctrl is probed. On the J722S EVM defconfig, pinctrl@f4000 (main_pmx0, the SoC's stock 7-entry gpio-range) is probed after relocation (caches on): single_add_gpio_func() takes ~18 ms there and ~1 ms with this change. When the node is probed before relocation (caches off) the same parse takes hundreds of ms; on a board that probes it pre-relocation and runs LPDDR4 clocked down it reached 723 ms, cut to 22 ms here. Any pinctrl-single user with a populated gpio-range property pays this cost. The phandle target is never dereferenced by this function (only the argument cells are stored), so resolve it only for the first entry to learn the per-entry cell count, then read the argument cells directly with ofnode_read_u32_index() and allocate the ranges in one block. A zero phandle still terminates the list, as in the original loop. This follows the existing pinctrl-single,gpio-range usage observed in current DTs, where entries use the same provider and therefore a uniform per-entry cell count.

Merge branch 'main' of https://git.u-boot-project.org/u-boot/custodians/u-boot-sunxi

2026-07-27T19:56:03Z

Beside a fix for a long standing bug in the A80 eMMC code, this adds SPI booting support for the Allwinner A523/A527/T527 class of boards. The second major feature is support for the secondary Ethernet controller on that same SoC. This might not be as important as for the kernel (I doubt that U-Boot acts as a router), but for once some boards only connect the secondary EMAC, and on others people might have the boot server only reachable via this port. There are some smaller fixes and improvements still queued up, but they need some more testing and are minor, so can land a bit later. The world build timed out, but the rest passed, and I booted that briefly on an A523 board with two Ethernet ports.

The Allwinner sun55i (A523/A527/T527) platform provide a Synopsys DesignWare Ethernet QOS IP block as the gmac1 controller, which uses pins PJ0 to PJ16. Add the gmac1 function to the pinctrl driver to support it. Signed-off-by: Junhui Liu Reviewed-by: Andre Przywara
