2017-12-13pinctrl: meson-axg: adjust spicc pin namingYixun Lan1-43/+43
According to datasheet, we should use numbers for the pin naming instead of letters. The patch here try to fix this to keep the consistency. This patch should not bring any functional change.

The pin controller has been updated in the Amlogic Meson AXG series, which use continuous 4-bit register to select function for each pin.

2017-10-17pinctrl: meson: rework pinmux opsJerome Brunet10-109/+194
This change prepare the introduction of new meson SoC. This new SoC will share the same gpio/pinconf registers but the pinmux part will be different. While the format of the data associated with each pinmux group will change, the way to handle pinmuxing will be similar. To deal with this new situation, the meson_pmx_struture is kept but the data associated to it is now generic. This allows to reuse the basic functions which would otherwise be copy/pasted in each pinmux driver (such as getting the name a count of groups and functions) Only the functions actually using this specific data is taken out of the common code and is handling the SoC pinmuxing Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Kevin Hilman <khilman@baylibre.com> Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2017-10-17pinctrl: meson: separate soc driversJerome Brunet8-69/+138
When meson pinctrl is enabled, all meson platforms pinctrl drivers are built in the kernel, with a significant amount of data. This leads to situation where pinctrl drivers targeting an architecture are also compiled and shipped on another one (ex: meson8 - ARM - compiled and shipped on ARM64 builds). This is a waste of memory we can easily avoid. This change makes 4 pinctrl drivers (1 per SoC) out the original single driver, allowing to compile and ship only the ones required.

I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal with the onset of Samsung patches. It works great. Apart from that it is a boring round, just incremental updates and fixes all over the place, no serious core changes or anything exciting like that. The most pleasing to see is Julia Cartwrights work to audit the irqchip-providing drivers for realtime locking compliance. It's one of those "I should really get around to looking into that" things that have been on my TODO list since forever.

New drivers or subdrivers: - Armada 37xx SoC pin controller and GPIO support. - Axis ARTPEC-6 SoC pin controller support. - AllWinner A64 R_PIO controller support, and opening up the AllWinner sunxi driver for ARM64 use. - Rockchip RK3328 support. - Renesas R-Car H3 ES2.0 support. - STM32F469 support in the STM32 driver. - Aspeed G4 and G5 pin controller support. Improvements: - a whole slew of realtime improvements to drivers implementing irqchips: BCM, AMD, SiRF, sunxi, rockchip. - switch meson driver to get the GPIO ranges from the device tree. - input schmitt trigger support on the Rockchip driver. - enable the sunxi (AllWinner) driver to also be used on ARM64 silicon. - name the Qualcomm QDF2xxx GPIO lines. - support GMMR GPIO regions on the Intel Cherryview. This fixes a serialization problem on these platforms. - pad retention support for the Samsung Exynos 5433. - handle suspend-to-ram in the AT91-pio4 driver. - pin configuration support in the Aspeed driver.

The current pinconf packed format allows only 16-bit argument limiting the maximum value 65535. For most types this is enough. However, debounce time can be in range of hundreths of milliseconds in case of mechanical switches so we cannot represent the worst case using the current format. In order to support larger values change the packed format so that the lower 8 bits are used as type which leaves 24 bits for the argument. This allows representing values up to 16777215 and debounce times up to 16 seconds. We also convert the existing users to use 32-bit integer when extracting argument from the packed configuration value.

2017-01-19pinctrl: meson: fix uart_ao_b for GXBB and GXL/GXMMartin Blumenstingl2-8/+6
The GXBB and GXL/GXM pinctrl drivers had a configuration which conflicts with uart_ao_a. According to the GXBB ("S905") datasheet the AO UART functions are: - GPIOAO_0: Func1 = UART_TX_AO_A (bit 12), Func2 = UART_TX_AO_B (bit 26) - GPIOAO_1: Func1 = UART_RX_AO_A (bit 11), Func2 = UART_RX_AO_B (bit 25) - GPIOAO_4: Func2 = UART_TX_AO_B (bit 24) - GPIOAO_5: Func2 = UART_RX_AO_B (bit 25) The existing definition for uart_AO_A already uses GPIOAO_0 and GPIOAO_1. The old definition of uart_AO_B however was broken, as it used GPIOAO_0 for TX (which would be fine) and two pins (GPIOAO_1 and GPIOAO_5) for RX (which does not make any sense). This fixes the uart_AO_B configuration by moving it to GPIOAO_4 and GPIOAO_5 (it would be possible to use GPIOAO_0 and GPIOAO_1 in theory, but all existing hardware uses uart_AO_A there). The fix for GXBB and GXL/GXM is identical since it seems that these specific pins are identical on both SoC variants.

Add EE domains pins for the NAND flash controller. Even tough we have no driver for the NAND flash controller yet, we need to have these pins in pinctrl as the actual pin are shared with the spifc controller. The bootloader on the S905-P200 setup pinmux for the NAND controller so we need the kernel to properly deactivate this if necessary.
