pinctrl: berlin: Make use of struct pinfunction

2024-06-17T07:23:34Z

Since pin control provides a generic data type for the pin function, use it in the driver. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20240530085745.1539925-2-andy.shevchenko@gmail.com Signed-off-by: Linus Walleij

pinctrl: berlin: switch to SPDX license identifier

2018-05-23T09:45:23Z

Use the appropriate SPDX license identifier in the berlin pinctrl driver source file and drop the previous license text. Signed-off-by: Jisheng Zhang Signed-off-by: Linus Walleij

pinctrl: berlin: fix my family name spelling

2015-10-16T14:28:57Z

My family name contained an accent when I submitted the Berlin pinctrl series in the first place. There was an encoding issue when the series was applied. Fix this. Signed-off-by: Antoine Ténart Acked-by: Sebastian Hesselbarth [Je me rendis tous les accents aigus] Signed-off-by: Linus Walleij

pinctrl: berlin: introduce berlin_pinctrl_probe_regmap()

2015-10-16T14:10:57Z

This is to prepare for the next berlin4ct support, where we won't use simple-mfd any more. Signed-off-by: Jisheng Zhang Acked-by: Sebastian Hesselbarth Acked-by: Antoine Tenart Signed-off-by: Linus Walleij

pinctrl: berlin: add the core pinctrl driver for Marvell Berlin SoCs

2014-05-22T22:05:00Z

The Marvell Berlin boards have a group based pinmuxing mechanism. This adds the core driver support. We actually do not need any information about the pins here and only have the definition of the groups. Let's take the example of the uart0 pinmuxing on the BG2Q. Balls BK4 and BH6 are muxed to respectively UART0 RX and TX if the group GSM12 is set to mode 0: Group Modes Offset Base Offset LSB Bit Width GSM12 3 sm_base 0x40 0x10 0x2 Ball Group Mode 0 Mode 1 Mode 2 BK4 GSM12 UART0_RX IrDA0_RX GPIO9 BH6 GSM12 UART0_TX IrDA0_TX GPIO10 So in order to configure BK4 -> UART0_TX and BH6 -> UART0_RX, we need to set (sm_base + 0x40 + 0x10) &= ff3fffff. As pin control registers are part of either chip control or system control registers, that deal with a bunch of other functions we rely on a regmap instead of exclusively remapping any resources.
