2018-11-28pinctrl: MediaTek: add pinctrl driver for MT7623 SoCRyder Lee

2018-11-28pinctrl: MediaTek: add pinctrl driver for MT7629 SoCRyder Lee
This patch adds pinctrl support for MT7629 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. Hence the driver also implements the gpio functionality through UCLASS_GPIO. This also creates a common file as there might be other chips that use the same binding and driver, then being a little more abstract could help in the long run.

2018-11-16pinctrl: stm32: Add get_pins_count() opsPatrice Chotard
Add get_pins_count ops to obtain the number of pins owns by a pin-controller. On STM32 SoCs bindings, each pin-controller owns several gpio banks. Each GPIO bank can own up to 16 pins. To obtain the total pins count, walk through each sub-nodes (ie GPIO banks) and sum each GPIO banks pins number. For that in probe() we build a list with each GPIO device reference found. This list will also be used with future get_pin_muxing and get_pin_name ops to speed up and optimize walk through all GPIO banks. As this code is common to all STM32 SoCs, this code is put under SPL_BUILD compilation flag to avoid to increase SPL code size for STM32F7 which is limited to 32Ko.

2018-11-14pinctrl: Remove DM_FLAG_PRE_RELOC flag in various driversBin Meng
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 <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-05-07regmap: clean up regmap allocationMasahiro Yamada
Putting zero length array at the end of struct is a common technique to embed arbitrary length of members. There is no good reason to let regmap_alloc_count() branch by "if (count <= 1)". As far as I understood the code, regmap->base is an alias of regmap->ranges[0].start, but it is not helpful but make the code just ugly. Rename regmap_alloc_count() to regmap_alloc() because the _count suffix seems pointless.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>

2018-03-30arm64: a37xx: pinctrl: Fix the pin 23 on south bridgeKen Ma
Pin 23 on South bridge does not belong to the rgmii group. It belongs to a separate group which can have 3 functions. Due to this the fix also have to update the way the functions are managed. Until now each groups used NB_FUNCS(which was 2) functions. For the mpp23, 3 functions are available but it is the only group which needs it, so on the loop involving NB_FUNCS an extra test was added to handle only the functions added. The bug was visible when the gpio regulator used the gpio 23, the whole rgmii group was setup to gpio which broke the Ethernet support on the Armada 3720 DB board. Thanks to this patch, the UHS SD cards (which need the vqmmc) _and_ the Ethernet work again.
