2016-04-21pinctrl: berlin: Use devm_pinctrl_register() for pinctrl registrationLaxman Dewangan1-1/+2
Use devm_pinctrl_register() for pin control registration. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Cc: Antoine Ténart <antoine.tenart@free-electrons.com> Acked-by: Antoine Tenart <antoine.tenart@free-electrons.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-04-01pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_mapIrina Tirdea1-1/+1
Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since it does not depend on device tree despite the current name. This will enforce a consistent naming in pinctr-utils.c and will make it clear it can be called from outside device tree (e.g. from ACPI handling code).

2015-12-01pinctrl: berlin: guard sub-directory with CONFIG_PINCTRL_BERLINMasahiro Yamada1-1/+1
CONFIG_PINCTRL_BERLIN is more suitable than CONFIG_ARCH_BERLIN to guard the drivers/pinctrl/berlin/ directory.

2015-10-16pinctrl: berlin: fix BG2CD field widthsThomas Hebb1-30/+32
The previous register layout was incorrect, many of the fields having fewer bits than were needed to represent all their modes. The new layout is taken from the bootloader source of a BG2CD device.

2015-06-10pinctrl: make pinctrl_register() return proper error codeMasahiro Yamada1-2/+2
Currently, pinctrl_register() just returns NULL on error, so the callers can not know the exact reason of the failure. Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some -ENOMEM on error of pinctrl_register(), although the error code might be different from the real cause of the error. This commit reworks pinctrl_register() to return the appropriate error code and modifies all of the pinctrl drivers to use IS_ERR() for the error checking and PTR_ERR() for getting the error code.

2014-09-23pinctrl: berlin: fix the dt_free_map functionAntoine Tenart1-20/+1
The berlin_pinctrl_dt_free_map function tries to free memory allocated and handled by the of subsystem. This is wrong and already handled by pinctrl_dt_free_maps() which calls of_node_put(). This patch fixes the Berlin pinctrl way of freeing its maps, avoiding a kernel BUG(), by using the common pinctrl_utils_dt_free_map function instead.

2014-09-04pinctrl: clean up after enable refactoringLinus Walleij1-4/+4
commit 2243a87d90b42eb38bc281957df3e57c712b5e56 "pinctrl: avoid duplicated calling enable_pinmux_setting for a pin" removed the .disable callback from the struct pinmux_ops, making the .enable() callback the only remaining callback. However .enable() is a bad name as it seems to imply that a muxing can also be disabled. Rename the callback to .set_mux() and also take this opportunity to clean out any remaining mentions of .disable() from the documentation.

2014-05-23pinctrl: berlin: add the core pinctrl driver for Marvell Berlin SoCsAntoine Tenart4-0/+418
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.
