The array u300_pmx_registers is not declared or used outside of the driver, so make it static to avoid the following warning: drivers/pinctrl/pinctrl-u300.c:673:11: warning: symbol 'u300_pmx_registers' was not declared. Should it be static? Signed-off-by:

drivers/pinctrl/bcm/Makefile properly builds individual drivers based on their respective Kconfig symbols. ARCH_BCM is currently a menuconfig option from arch/arm/mach-bcm/Kconfig, which is fine, but prevents ARM64 platforms which do not have such menuconfig option from building their pinctrl drivers, so let's get rid of that dependency.

The Kconfig currently controlling compilation of this code is: drivers/pinctrl/Kconfig:config PINCTRL_AT91PIO4 drivers/pinctrl/Kconfig: bool "AT91 PIO4 pinctrl driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. 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. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

Add pin configuration and pinmux support for UniPhier PH1-LD11 SoC. Signed-off-by:
-
Masahiro Yamada authored
Currently, the UniPhier pinctrl driver itself is a syscon, but it turned out much more reasonable to make it a child node of a syscon because our syscon node consists of a bunch of system configuration registers, not only pinctrl, but also phy, and misc registers. It is difficult to split the node. To allow to migrate to the new DT structure, this commit adds new compatible strings to not disturb the existing DT. After a while, the old binding will be removed.

Masahiro Yamada authored
PH1-LD4 and PH1-sLD8 SoCs have pins that support pin configuration (pin biasing, drive strength control), but not pin-muxing. Allow to fill the mux value table with -1 for those pins; pins with mux value -1 will be skipped in the pin-mux set function. The mux value type should be changed from "unsigned" to "int" in order to accommodate -1 as a special case. Signed-off-by:

Upcoming new pinctrl drivers for PH1-LD11 and PH-LD20 support input signal gating for each pin. (While, existing ones only support it per pin-group.) This commit updates the core part for that. Signed-off-by:

Masahiro Yamada authored
The core part of the UniPhier pinctrl driver needs to support a new capability for upcoming UniPhier ARMv8 SoCs. This sometimes happens because pinctrl drivers include really SoC-specific stuff. This commit intends to tidy up SoC-specific parameters of the existing drivers before adding the new one. Having just one flag would be better than adding a new struct member every time a new SoC-specific capability comes up. At this time, there is one flag, UNIPHIER_PINCTRL_CAPS_DBGMUX_SEPARATE. This capability (I'd say rather quirk) was added for PH1-Pro4 and PH1-Pro5 as requirement from a customer. For those SoCs, one pin-mux setting is controlled by the combination of two separate registers; the LSB bits at register offset (8 * N) and the MSB bits at (8 * N + 4). Because it is impossible to update two separate registers atomically, the LOAD_PINCTRL register should be set in order to make the pin-mux settings really effective. Signed-off-by:

Unfortunately, the pin number of the new SoC, PH1-LD11, is not contiguous. The base frame work must be adjusted to support the new SoC pinctrl driver. The pin_desc_get() exploits radix-tree for pin look-up, so it works more efficiently with sparse pin space. Signed-off-by:

The new ARMv8 SoC, PH1-LD20, supports more fine-grained drive strength control. Drive strength of some pins are controlled by 3-bit width registers (8-level granularity). Signed-off-by:

The new ARMv8 SoC, PH1-LD20, supports more fine-grained drive strength control. Some of the configuration registers on it have 3-bit width. The feature will be supported in the next commit, but a problem is that macro names are getting longer and longer in the current naming scheme. Before moving forward, this commit renames macros as follows: UNIPHIER_PIN_DRV_4_8 -> UNIPHIER_PIN_DRV_1BIT UNIPHIER_PIN_DRV_8_12_16_20 -> UNIPHIER_PIN_DRV_2BIT UNIPHIER_PIN_DRV_FIXED_4 -> UNIPHIER_PIN_DRV_FIXED4 UNIPHIER_PIN_DRV_FIXED_5 -> UNIPHIER_PIN_DRV_FIXED5 UNIPHIER_PIN_DRV_FIXED_8 -> UNIPHIER_PIN_DRV_FIXED8 Signed-off-by:

Currently, every SoC driver defines struct pinctrl_desc statically, i.e. it consumes memory footprint even if it is not probed. In multi-platform, many pinctrl drivers are linked (generally as built-in objects), although only one of them is actually used. So, it is reasonable to allocate memory dynamically where possible.

To i.MX7D, there are two iomux controllers, iomuxc and iomuxc_lpsr. They should not share one pin controller descriptor, otherwise the value filled into imx_pinctrl_desc when probing the first iomux controller will be overridden when probing the second one. In this patch, discard the static allcoated imx_pinctrl_desc and switch to dynamically allcate pin controller descriptor for each iomux controller. Signed-off-by:
