ARM: uniphier: remove sLD3 SoC support

2017-08-20T14:05:39Z

This SoC is too old. It is difficult to maintain any longer. Signed-off-by: Masahiro Yamada

ARM: uniphier: remove SPL support for ARMv8 SoCs

2017-07-26T13:27:15Z

It has been a while since ARM Trusted Firmware supported UniPhier SoC family. U-Boot SPL was intended as a temporary loader that runs in secure world. It is a maintenance headache to support two different boot mechanisms. Secure firmware is realm of ARM Trusted Firmware and now U-Boot only serves as a non-secure boot loader for UniPhier ARMv8 SoCs.

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

dm: Rename dev_addr..() functions

2017-06-01T13:03:01Z

These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file. Signed-off-by: Simon Glass

dm: Use dm.h header when driver mode is used

2017-06-01T12:57:52Z

This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass

pinctrl: uniphier: support pin configuration

2017-02-22T23:37:56Z

Support the following DT properties: "bias-disable" "bias-pull-up" "bias-pull-down" "bias-pull-pin-default" "input-enable" "input-disable" My main motivation is to support pull up/down biasing. For Pro5 and later SoCs, the pupdctrl register number is the same as the pinmux number, so this feature can be supported without having big pin tables. Signed-off-by: Masahiro Yamada

pinctrl: uniphier: fix unused-const-variable warnings for GCC 6.x

2016-10-18T05:06:46Z

Marek reports warnings in UniPhier pinctrl drivers when compiled by GCC 6.x, like: drivers/pinctrl/uniphier/pinctrl-uniphier-ld20.c:58:18: warning: 'usb3_muxvals' defined but not used [-Wunused-const-variable=] static const int usb3_muxvals[] = {0, 0}; ^~~~~~~~~~~~ My intention here is to compile minimum set of pin data for SPL to save memory footprint, but GCC these days is clever enough to notice unused data arrays. We can fix it by sprinkling around __maybe_unused on those arrays, but I did not do that because they are counterparts of the pinctrl drivers in Linux. All the pin data were just copy-pasted from Linux and are kept in sync for maintainability. I chose a bit tricky way to fix the issue; calculate ARRAY_SIZE of *_pins and *_muxvals and set their sum to an unused struct member. This trick will satisfy GCC because the data arrays are used anyway, but such data arrays will be dropped from the final binary because the pointers to them are not used.
