pinctrl: uniphier: Add USB device pinmux settings

2022-02-11T00:37:21Z

Add USB device pinmux settings for PXs2 and PXs3 SoCs. Only pins for ports 0 and 1 support USB device mode. Signed-off-by: Kunihiko Hayashi Link: https://lore.kernel.org/r/1643376903-18623-4-git-send-email-hayashi.kunihiko@socionext.com Signed-off-by: Linus Walleij

pinctrl: uniphier: Divide pinmux group to support 1ch and 2ch I2S

2022-02-11T00:37:21Z

Current pinmux group for audio in/out assumes 4ch I2S case but the UniPhier AIO hardware also supports 1ch and 2ch I2S. So divide current ain1 group into ain1, ain1_dat2 and ain1_dat4 groups. Divide other ain and aout in the same way.

pinctrl: uniphier: Replace zero-length array with flexible-array member

2020-02-21T14:36:24Z

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

pinctrl: uniphier: Add another audio I/O pin-mux settings for LD20

2019-08-05T11:18:34Z

This adds support for pinmux settings of aout1b group. This group includes audio I/O signals derived from xirq pins, and it is equivalent to "aout1" in functionality.
