pinctrl: pinmux: add function selector to pinmux-functions
Add the function selector to the pinmux-functions debugfs output. This is an integer which is the index into the pinmux function tree. It will make it easier to correlate function name to function selector without having to count the lines in the output. Example output of "pinmux-functions": function 0: pinmux-uart0-pins, groups = [ pinmux-uart0-pins ] function 1: pinmux-uart1-pins, groups = [ pinmux-uart1-pins ] function 2: pinmux-uart2-pins, groups = [ pinmux-uart2-pins ] function 3: pinmux-mmc0-pins, groups = [ pinmux-mmc0-pins ] function 3: pinmux-mmc1-pins, groups = [ pinmux-mmc1-pins ] function 5: pinmux-i2c0-pins, groups = [ pinmux-i2c0-pins ] function 6: pinmux-i2c1-pins, groups = [ pinmux-i2c1-pins ] function 7: pinmux-i2c2-pins, groups = [ pinmux-i2c2-pins ] function 8: pinmux-pwm0-pins, groups = [ pinmux-pwm0-pins ] function 9: pinmux-pwm1-pins, groups = [ pinmux-pwm1-pins ] function 10: pinmux-adc-pins, groups = [ pinmux-adc-pins ] Cc: Jason Kridner <jkridner@beagleboard.org> Cc: Robert Nelson <robertcnelson@beagleboard.org> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Tony Lindgren <tony@atomide.com> Cc: Andy Shevchenko <andy.shevchenko@gmail.com> Cc: Alexandre Belloni <alexandre.belloni@bootlin.com> Signed-off-by: Drew Fustini <drew@beagleboard.org> Link: https://lore.kernel.org/r/20210123202212.528046-1-drew@beagleboard.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
