pinctrl: rockchip: fix mux route data for rk3568

2023-01-17T13:16:45Z

IO mux selection is configured in PMU_GRF_SOC_CON4 and GRF_IOFUNC_SEL0-5 regs on RK3568. pwm0-2 is configured in PMU_GRF reg and the rest is configured in GRF_IOFUNC regs according to TRM [1]. Update mux route data to reflect this and use proper detection pin for UART1 IO mux M1. This fixes HDMITX IO mux M1 selection and makes it possible to enable HDMI CEC on my Radxa ROCK 3 Model A v1.31 board.

pinctrl: rockchip: fix reading pull type on rk3568

2023-01-16T12:42:28Z

When reading pinconf-pins from debugfs it fails to get the configured pull type on RK3568, "unsupported pinctrl type" error messages is also reported. Fix this by adding support for RK3568 in rockchip_get_pull, including a reverse of the pull-up value swap applied in rockchip_set_pull so that pull-up is correctly reported in pinconf-pins. Also update the workaround comment to reflect affected pins, GPIO0_D3-D6.

pinctrl: sp7021: fix unused function warning

2022-12-29T01:07:25Z

sppctl_gpio_inv_get is only used from the debugfs code inside of an #ifdef, so we get a warning without that: drivers/pinctrl/sunplus/sppctl.c:393:12: error: 'sppctl_gpio_inv_get' defined but not used [-Werror=unused-function] 393 | static int sppctl_gpio_inv_get(struct gpio_chip *chip, unsigned int offset) | ^~~~~~~~~~~~~~~~~~~ Replace the #ifdef with an IS_ENABLED() check that avoids the warning.

pinctrl: thunderbay: fix possible memory leak in thunderbay_build_functions()

2022-12-06T14:28:14Z

The thunderbay_add_functions() will free memory of thunderbay_funcs when everything is ok, but thunderbay_funcs will not be freed when thunderbay_add_functions() fails, then there will be a memory leak, so we need to add kfree() when thunderbay_add_functions() fails to fix it. In addition, doing some cleaner works, moving kfree(funcs) from thunderbay_add_functions() to thunderbay_build_functions().

pinctrl: intel: Save and restore pins in "direct IRQ" mode

2022-11-28T20:41:31Z

The firmware on some systems may configure GPIO pins to be an interrupt source in so called "direct IRQ" mode. In such cases the GPIO controller driver has no idea if those pins are being used or not. At the same time, there is a known bug in the firmwares that don't restore the pin settings correctly after suspend, i.e. by an unknown reason the Rx value becomes inverted. Hence, let's save and restore the pins that are configured as GPIOs in the input mode with GPIROUTIOXAPIC bit set.
