From 2cbd230091c99ba68ac1888d3b37fc6ca56fbb75 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sat, 2 Nov 2024 20:01:05 +0000 Subject: [PATCH] mediatek: pinctrl-mt7988: add missing PWM pingroups Add additionals possible pinctrl group for pwm2~7 on pins pin 4 (GPIO_A) pwm7 pin 58 (JTAG_JTDI) pwm2 pin 59 (JTAG_JTDO) pwm3 pin 60 (JTAG_JTMS) pwm4 pin 61 (JTAG_JTCLK) pwm5 pin 62 (JTAG_JTRST_N) pwm6 They can be useful e.g. on the BPi-R4 as in that way pwm2~6 can be exposed on the 26-pin header (pwm6 always, pwm2~5 instead of the full UART).
