2021-03-29pinctrl: add a pincontrol driver for BCM6362Álvaro Fernández Rojas
Add a pincotrol driver for BCM6362. BCM6362 allows muxing individual GPIO pins to the LED controller, to be available by the integrated wifi, or other functions. It also supports overlay groups, of which only NAND is documented.

Implement support for pull-up (most pins) and pull-down (ASEBRK#/ACK) handling for R-Car M2-W and M2-N, and RZ/G1M and RZ/G1N SoCs, using the common R-Car bias handling. Note that on RZ/G1 SoCs, the "ASEBRK#/ACK" pin is called "ACK", but the code doesn't handle that naming difference. Hence users should use the R-Car naming in DTS files.

2021-03-24pinctrl: renesas: Add support for R-Car SoCs with pull-down only pinsGeert Uytterhoeven
Currently, the common R-Car bias handling supports pin controllers with either: 1. Separate pin Pull-Enable (PUEN) and pin Pull-Up/Down control (PUD) registers, for controlling both pin pull-up and pin pull-down, 2. A single pin Pull-Up control register (PUPR), for controlling pin pull-up. Add support for a variant of #2, where some bits in the single pin Pull-Up control register (PUPR) control pin pull-down instead of pin pull-up. This is the case for the "ASEBRK#/ACK" pin on R-Car M2-W, M2-N, and E2, and the "ACK" pin on RZ/G1M, RZ/G1N, RZ/G1E, and RZ/G1C. To describe such a register, SoC-specific drivers need to provide two instances of pinmux_bias_reg: a first one with the puen field filled in, listing pins with pull-up functionality, and a second one with the pud field filled in, listing pins with pull-down functionality.

Add "pinmux-select" to debugfs which will activate a pin function for a given pin group: echo "<group-name function-name>" > pinmux-select The write operation pinmux_select() handles this by checking that the names map to valid selectors and then calling ops->set_mux(). The existing "pinmux-functions" debugfs file lists the pin functions registered for the pin controller. For example: function: pinmux-uart0, groups = [ pinmux-uart0-pins ] function: pinmux-mmc0, groups = [ pinmux-mmc0-pins ] function: pinmux-mmc1, groups = [ pinmux-mmc1-pins ] function: pinmux-i2c0, groups = [ pinmux-i2c0-pins ] function: pinmux-i2c1, groups = [ pinmux-i2c1-pins ] function: pinmux-spi1, groups = [ pinmux-spi1-pins ] To activate function pinmux-i2c1 on group pinmux-i2c1-pins: echo "pinmux-i2c1-pins pinmux-i2c1" > pinmux-select Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Tony Lindgren <tony@atomide.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Drew Fustini <drew@beagleboard.org> Link: https://lore.kernel.org/r/20210302053059.1049035-3-drew@beagleboard.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2021-03-10pinctrl: use to octal permissions for debugfs filesDrew Fustini
Switch over pinctrl debugfs files to use octal permissions as they are preferred over symbolic permissions. Refer to commit f90774e1fd27 ("checkpatch: look for symbolic permissions and suggest octal instead"). Note: S_IFREG flag is added to the mode by __debugfs_create_file() in fs/debugfs/inode.c Suggested-by: Joe Perches <joe@perches.com> Suggested-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Drew Fustini <drew@beagleboard.org> Link: https://lore.kernel.org/r/20210302053059.1049035-2-drew@beagleboard.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
