2017-02-13pinctrl: mvebu: make bool drivers explicitly non-modularPaul Gortmaker
None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get the exact same change, so they are handled in batch. Changes are (1) use builtin_platform_driver, (2) dont use module.h (3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE, and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags. For the dove driver we explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We deleted the MODULE_LICENSE etc. tags since all that information is already contained at the top of the file in the comments.

Provide per-control private data into each mvebu pinctrl method, which will allow us to provide some completely generic helpers without the global variable and per-instance function definitions that would be required when we have multiple pin controllers on a SoC.

2017-01-18pinctrl: mvebu: constify mvebu_mpp_ctrl structuresRussell King
As the mvebu_mpp_ctrl structures contain function pointers, it is preferable for these to be made read-only to prevent the function pointers being modified. So make these const. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2015-06-10pinctrl: mvebu: armada-{370,375,38x,39x,xp}: normalize TDM pinsThomas Petazzoni
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.

2015-06-10pinctrl: mvebu: armada-{370,375,38x,39x}: normalize dev pinsThomas Petazzoni
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.

2015-06-10pinctrl: mvebu: armada-{38x,39x,xp}: normalize naming of DRAM functionsThomas Petazzoni
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.

2015-06-10pinctrl: mvebu: armada-{375,38x,39x}: normalize naming of PTP subnamesThomas Petazzoni
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.

2015-06-10pinctrl: mvebu: armada-38x: fix incorrect total number of GPIOsThomas Petazzoni
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.

2015-06-10pinctrl: mvebu: armada-38x: fix PCIe functionsThomas Petazzoni
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.

2014-02-25pinctrl: mvebu: add pin-muxing driver for the Marvell Armada 380/385Thomas Petazzoni
The Marvell Armada 380/385 are new ARM SoCs from Marvell, part of the mvebu family, but using a Cortex-A9 CPU core. In terms of pin-muxing, it is similar to Armada 370 and XP for the register layout, only different in the number of available pins and their functions. Therefore, we simply use the existing drivers/pinctrl/mvebu/ infrastructure, with no other changes that the list of pins and corresponding functions.
