pinctrl: spacemit: fix typo in PRI_TDI pin name

2025-09-08T12:24:03+00:00

The datasheet lists this signal as PRI_TDI, not PRI_DTI. Fix the pin name to match the documentation and JTAG naming convention (TDI = Test Data In). Signed-off-by: Hendrik Hamerlinck Reviewed-by: Yixun Lan Signed-off-by: Linus Walleij

pinctrl: spacemit: remove extra line in debug output

2025-08-18T15:17:20+00:00

The debug output for spacemit_pinconf_dbg_show() prints an extra newline at the end. This is redundant as pinconf_pins_show() in pinconf.c already adds a newline in its for loop. Remove the newline to avoid the extra line in the output. Example current output: $ cat /sys/kernel/debug/pinctrl/d401e000.pinctrl/pinconf-pins Pin config settings per pin Format: pin (name): configs pin 0 (GPIO_00): , bias pull disabled, io type (Fixed/1V8), drive strength (32 mA), register (0x1041) pin 1 (GPIO_01): slew rate (0x0), bias pull disabled, io type (Fixed/1V8), drive strength (32 mA), register (0x1041) pin 2 (GPIO_02): slew rate (0x0), bias pull disabled, io type (Fixed/1V8), drive strength (32 mA), register (0x1041) ...

pinctrl: spacemit: enable config option

2025-02-25T16:22:36+00:00

Pinctrl is an essential driver for SpacemiT's SoC, The uart driver requires it, same as sd card driver, so let's enable it by default for this SoC. The CONFIG_PINCTRL_SPACEMIT_K1 isn't enabled when using 'make defconfig' to select kernel configuration options. This result in a broken uart driver where fail at probe() stage due to no pins found.

pinctrl: spacemit: fix double free of map

2024-10-28T12:54:04+00:00

The map pointer is freed by pinctrl_utils_free_map(). It must not be a devm_ pointer or it leads to a double free when the device is unloaded. This is similar to a couple bugs Harshit Mogalapalli fixed earlier in commits 3fd976afe974 ("pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()") and 4575962aeed6 ("pinctrl: sophgo: fix double free in cv1800_pctrl_dt_node_to_map()").
