* rockchip: rk3288: Fix pinctrl for GPIO bank 0John Keeping2016-07-31-2/+19
| | | | | | | | | | | | | | | | Bank 0 is the "PMU GPIO" bank which is controlled by the PMU registers rather than the GRF registers. In the GRF the top half of the register is used as a mask so that some bits can be updated without affecting the others, but in the PMU this feature is not provided and the top half of the register is reserved. Take the same approach as the Linux driver to update the value via read-modify-write but setting the mask for only the bits that have changed. The PMU registers ignore the top 16 bits so this works for both GRF and PMU iomux registers. Signed-off-by: John Keeping <john@metanate.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>

* pinctrl: uniphier: support pin configuration for dedicated pinsMasahiro Yamada2016-07-02-154/+149
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | PH1-LD11 and PH1-LD20 have much pin controlling in common, so I added a single driver shared between them in the initial commit. However, the Ethernet pin-mux settings I am going to add are different with each other, and they may diverge more as the progress of development. Split it into two dedicated drivers.

* pinctrl: uniphier: allow to have pinctrl node under syscon nodeMasahiro Yamada2016-07-02-12/+12
| | | | | | | | | | | 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. This commit allows to migrate to the new DT structure. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* pinctrl: uniphier: introduce capability flagMasahiro Yamada2016-04-01-27/+29
| | | | | | | | | | | | | | | | | | | | | 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 new ones. Having flags would be better than adding new members 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 our 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.

* pinctrl: uniphier: set input-enable before pin-muxingMasahiro Yamada2016-03-09-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | While IECTRL is disabled, input signals are pulled-down internally. If pin-muxing is set up first, glitch signals (Low to High transition) might be input to hardware blocks. Bad case scenario: [1] The hardware block is already running before pinctrl is handled. (the reset is de-asserted by default or by a firmware, for example) [2] The pin-muxing is set up. The input signals to hardware block are pulled-down by the chip-internal biasing. [3] The pins are input-enabled. The signals from the board reach the hardware block. Actually, one invalid character is input to the UART blocks for such SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the power on reset. To avoid such problems, pins should be input-enabled before muxing.

Add PINCTRL_IMX PINCTRL_IMX6 Kconfig entry. 3. To the pinctrl_ops implementation, only set_state is implemented. To i.MX6/7, the pinctrl dts entry is as following: &iomuxc { pinctrl-names = "default"; pinctrl_csi1: csi1grp { fsl,pins = < MX6UL_PAD_CSI_MCLK__CSI_MCLK 0x1b088 MX6UL_PAD_CSI_PIXCLK__CSI_PIXCLK 0x1b088 MX6UL_PAD_CSI_VSYNC__CSI_VSYNC 0x1b088 >; }; [.....] }; there is no property named function or groups. So pinctrl_generic_set_state can not be used here. 5. This driver is a simple implementation for i.mx iomux controller, only parse the fsl,pins property and write value to registers. 6.
