pinctrl: imx: Define imx6_pinctrl_soc_info in .data section

2019-06-11T08:43:00Z

This commit is necessary to be able to re-use the pinctrl code in early SPL to properly configure pins. The problem is that those "static" structures (without explicit initialization) are placed in the SDRAM area, which corresponds to u-boot proper (not even SPL). Hence, when one wants to configure pins before relocation via DTS/DM, the board hangs (imx6q SoC powered one) as only OCRAM area is available (0x009xxxxx). This commit prevents from this issue by moving the imx6_pinctrl_soc_info structure to data section (from BSS). Signed-off-by: Lukasz Majewski Reviewed-by: Peng Fan

pinctrl: imx: Fix select input issue

2019-01-28T19:35:47Z

The pinctrl supports to set any bit in input register on iMX6 if the MSB of input value is 0xff. But the driver uses signed int for input value, so when executing the codes below, it won't meet. Because this is arithmetic right shift. if (input_val >> 24 == 0xff) Fix the issue by changing the input_val, config_val and mux_mode to u32.

pinctrl: Remove DM_FLAG_PRE_RELOC flag in various drivers

2018-11-14T17:16:28Z

When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng Reviewed-by: Simon Glass

pinctrl: Add pinctrl driver for i.MX8

2018-10-22T10:59:01Z

Add pinctrl driver for i.MX8. The pads configuration is controlled by SCU, so need to ask SCU to configure pads through scfw API. Add pinctrl-scu to invoke sc_pad_set to configure pads. Add a new flag IMX8_USE_SCU to differentiate i.MX8 from other platforms which could directly configure pads from Acore side. Add CONFIG_PINCTRL_IMX8 as the built gate.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

pinctrl: imx7ulp: Add new info instance for iomuxc1

2017-08-23T08:48:15Z

To i.MX7ULP, we need to create two info instances for iomux0 and iomux1 respectively, otherwise iomuxc0/1 will share one info instance and use one base, because imx_pinctrl_probe will use info to store base address and etc. But iomuxc0/1 actually have different base address.
