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: imx6ul: Fix pinctrl data overlapped with DT area

2017-11-27T09:36:40Z

before relocation pinctrl data BSS is overlapping DT area, when .data is using uninitialized global variable, imx6_pinctrl_soc_info. So assign them flags ZERO_OFFSET_VALID to prevent BSS overlap Suggested-by: Lokesh Vutla Reported-by: Jagan Teki Signed-off-by: Jagan Teki

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.

when using SHARE_MUX_CONF_REG, wrong mask is used for writing config value, which causes mux value is cleared. Signed-off-by: Peng Fan Cc: Simon Glass Cc: Stefano Babic

dm: Fix up inclusion of common.h

2017-06-01T13:03:03Z

It is good practice to include common.h as the first header. This ensures that required features like the DECLARE_GLOBAL_DATA_PTR macro, configuration options and common types are available. Fix up some files which currently don't do this. This is necessary because driver model will soon start using global data and configuration in the dm/read.h header file, included via dm.h. The gd->fdt_blob value will be used to access the device tree and CONFIG options will be used to determine whether to support inline functions in the header file. Signed-off-by: Simon Glass

pinctrl: imx: fix memory leak

2017-05-18T09:24:34Z

Each time set_state is called, a new piece memory will be allocated for pin_data, but not freed, this will incur memory leak. When error, the devm API could not free memory automatically. So need call devm_kfree when error. Issue reported by Coverity Signed-off-by: Peng Fan Cc: Simon Glass Cc: Stefan Agner Cc: Stefano Babic
