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.

The Armada 39x SoC family has grown a new variant, the Armada 395, which sits between the Armada 390 and Armada 398 in terms of features. This commit adds support for this additional variant to the Armada 39x pinctrl driver. Signed-off-by:

This commit normalizes the subnames of the reference clock MPP pins in the Armada 39x pinctrl driver to match with the name used on other SoCs. Since only the subnames are changed, DT backward compatibility is not affected. Signed-off-by:

After updating to the latest Armada XP datasheet, we discovered that there is a second SPI bus accessible from the MPP pins, called 'spi1'. In order to be consistent with other SoCs having two SPI busses, this commit renames the functions of the first SPI bus to 'spi0' instead of just 'spi'. This commit obviously breaks the DT backward compatibility for the people using the "spi" function name in their Device Tree. Signed-off-by:

Across all SoCs, even on Armada 370 for SPI0, the clock pin uses the 'sck' subname and not 'clk', so this commit adjusts the code and documentation accordingly. Since this commit only changes the subname, DT backward compatibility is not affected. Signed-off-by:

For consistency with the datasheet, this commit renames the VDD function of the MPP4 pin. While this changes the DT compatibility, it is not considered to be a problem since this pin is unlikely to be used for anything but debugging purposes. Signed-off-by:

There was an off-by-one in the documentation of the ge1(txd[0-3]) pins, which is fixed by this commit. Since the driver was correct, and the subnames are anyway not used in the DT binding itself, there is no need to push this documentation fix for stable. Signed-off-by:

This commit normalizes the naming of the Ethernet txclkout pin to be the same accross Marvell SoCs. It is worth mentioning that the DT binding documentation of the Armada XP was wrong for MPP12: it said the function was ge1(txd0), while it is in fact ge1(txclkout). It is however not really a fix worth sending to stable since it does not change the behavior, and the driver itself was correct. Since only the subnames are changed, DT backward compatibility is not affected. Signed-off-by:

This commit normalizes the naming of PCIe pins to use 'rstout' instead of 'rstoutn' or 'rst-out'. Since only the subnames are changed, DT compatibility is not affected. Signed-off-by:

This commit normalizes the naming of the TDM pins accross the different Marvell SoCs. Mainly it consists in: * Removing the 'n' from signal names: 'intn' becomes 'int' and 'rstn' becomes 'rst' * Renaming the main name 'tdm2c' to 'tdm' on Armada 38x. * Change the main name 'tdm-1' to 'tdm' for one of the pins of the Armada XP The last two changes affect DT compatibility, but since the TDM interface is nowhere near being supported in mainline, it should not be considered to be a serious problem at this point.

All SoCs use "nand" to designate NAND pins, only Armada 39x is using "nd", which is not consistent. This commit fixes that by renaming the corresponding functions. It also changes the subnames from rbn0/rbn1 to rb0/rb1, to respect the convention used everywhere that we don't encode the 'n' part of signal names. While this commit changes the main name of function, therefore potentially breaking the DT compatibility, this is not a problem since Armada 39x is a brand new SoC which isn't used in production yet.

This commit modifies the definition of the Device Bus interface pins to be consistent accross SoCs. Especially, it removes the 'n' indicators that we don't encode in the subnames of pins: 'dev(wen0)' becomes 'dev(we0)' 'dev(wen1)' becomes 'dev(we1)' 'dev(oen)' becomes 'dev(oe)' etc. In addition, it fixes the Armada 375 DT binding documentation, which forgot to document the 'dev' function for MPP46, MPP57 and MPP63. Since only the subnames are changed, this commit does not affect DT compatibility. Signed-off-by:

In order to be consistent with the datasheet and some other SoCs, this commit renames the SDIO pins of the Armada 39x from "sd" to "sd0". While this changes the DT binding, this is not a problem since Armada 39x is a brand new SoC which isn't used in production yet (so now is the right time to fix such things). Signed-off-by:

This commit makes the naming of SATA related MPP functions consistent accross SoCs by adjusting the Armada 39x definition to use "prsnt" instead of "present". Since only the subnames are changed, the DT binding is not modified at all. Signed-off-by:

This commit makes the dram functions naming (both the name and subname) consistent accross SoC, by using: dram(vttctrl) dram(deccerr) in all Marvell SoCs. Due to the change to the name, it changes the DT binding, but these functions are not used by any in-tree Device Tree file, and are very unlikely to be used by anyone. Signed-off-by:

The subnames are purely informative, but it's nicer when they match accross SoCs. This commit adjusts the Armada 375, Armada 38x and Armada 39x MPP definitions so that the subnames of the PTP pins match the ones used on Armada XP and Kirkwood. Signed-off-by:

The pinctrl_gpio_range[] array described a first bank of 32 GPIOs and a second one of 27 GPIOs. However, since there is a total of 60 MPP pins that can be muxed as GPIOs, the second bank really has 28 GPIOs. Signed-off-by:

A new revision of the Marvell Armada 38x hardware datasheet unveiled that the definition of some of the PCIe functions were not correct. This commit fixes the pinctrl driver accordingly. Some PCIe functions simply do not exist, some of the PCIe functions in fact were corresponding to other functions, and some PCIe functions have been added. Note: the seemingly unrelated removal of spi(cs2) on MPP47 is related: this function is in fact implemented on MPP43, instead of a PCIe function. Signed-off-by:
