This patch adds support for SAMSUNG's/NEXELL's ARM Cortex-A9 based
S5P4418 SoC, especially FriendlyARM's NanoPi2 and NanoPC-T2 boards.
It is based on the following FriendlyARM's U-Boot version:
https://github.com/friendlyarm/u-boot/tree/nanopi2-v2016.01.
Main changes in relation to nanopi2-v2016.01:
- Cosmetic changes due to patman warnings/errors.
- MMC and Video drivers changed to DM.
- Configs reworked (e.g. "CONFIG_..." moved from s5p4418_nanopi2.h
to s5p4418_nanopi2_defconfig)
- SPL related files are not included.
- MACH_TYPE_S5P4418 is not defined/used anymore.
- arch/arm/mach-nexell/include/mach/boot0.h added to generate the NSIH
(Nexell System Information Header), substitudes tools/nexell.
- board/s5p4418/ renamed to board/friendlyarm/
- Only the NanoPi2 and NanoPC-T2 boards are supported yet because I
do only have the NanoPC-T2 board to test the code (this board uses
the NanoPi2 code).
- USB is not supported yet.
- pinctrl-driver/dt is used for mmc and i2c now instead of configuring
the I/O-pins in the drivers.
- '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where
possible (and similar).
- livetree API (dev_read_...) is used instead of fdt one (fdt...).
The patch-series has been checked by buildman (all arm boards and two
m68k boards = M5235EVB):
buildman --step 0 -b master arm
buildman --step 0 -b master M5235EVB
There have been no new warnings or errors.
Changes in v4:
- cosmetic changes in nx_i2c.c: if-else block simplified, defines used
for constant values.
Changes in v3:
- arch/arm/mach-nexell/Kconfig: "NEXELL_COMMON" removed, has not been
used at all. NEXELL_ARMV7_COMMON and NEXELL_ARMV8_COMMON removed,
has been used only in the Kconfig at ARCH_S5P4418 and ARCH_S5P6818.
Used "select ..."-statements moved appropriately.
Missing helps added.
- arch/arm/mach-nexell/timer.c: '#include <log.h>' inserted because
it has been removed from common.h.
- '#ifdef...' changed to 'if (IS_ENABLED(CONFIG...))' where possible
because of appropriate warnings of patman.
- Changed to livetree API as proposed by patman:
fdtdec_get_int() --> dev_read_s32_default()
fdt_getprop() --> dev_read_string()
- pinctrl-driver/dt is used now instead of configuring the i2c I/O-pins
in the i2c-driver.
- drivers/i2c/nx_i2c.c: '#include <log.h>' inserted because it has been
removed from common.h.
- Changed to livetree API as proposed by patman:
fdtdec_get_int() --> dev_read_s32_default()
- nexell_dw_mmc_dm.c renamed (back) to nexell_dw_mmc.c
- pinctrl-driver/dt is used now instead of configuring the mmc I/O-pins
in the mmc-driver.
- nexell_dwmmc_ofdata_to_platdata() reworked, i.e. valid default values
are used now (where possible) and the appropriate if-blocks have
been removed.
- "nexell," removed from dt-properties, e.g. "nexell,bus-width" changed
to "bus-width".
- new dt-property "mmcboost" is used now instead of "CONFIG_BOOST_MMC"
which was not defined anywhere.
- Boot error "Loading Environment from MMC... *** Warning - No block
device, using default environment" after updating local repository.
Bugfix in drivers/mmc/nexell_dw_mmc.c: "#include <clk.h>" changed to
"#include <asm/arch/clk.h>". This Bug showed up now because of the
commit "dm: clk: add stub when CONFIG_CLK is deactivated" where
include/clk.h has been changed.
- drivers/mmc/nexell_dw_mmc.c: '#include <log.h>' inserted because it
has been removed from common.h.
- Kconfig: Missing helps added.
- Changed to livetree API as proposed by patman:
fdt_stringlist_count() --> dev_read_string_count()
fdt_stringlist_get() --> dev_read_string_index()
fdtdec_get_int() --> dev_read_s32_default()
- doc/device-tree-bindings/pinctrl/nexell,s5pxx18-pinctrl.txt added.
- Handling of Configs for LCD backlight control reworked because (among
others) not setting CONFIG_S5P4418_ONEWIRE and/or CONFIG_PWM_NX has
caused errors when compiling board/friendlyarm/nanopi2/onewire.c.
- pwm.h: () around macro argument x added to avoid precedence issues.
- drivers/video/nexell/s5pxx18_dp_hdmi.c: '#include <log.h>' and
'#include <linux/delay.h>' inserted because it has been removed from
common.h.
- drivers/video/nexell_display.c: '#include <command.h>' inserted because
'#include <image.h>' (includes command.h) has been removed from common.h.
- Changed to livetree API as proposed by patman:
fdtdec_get_int() --> ofnode_read_s32_default()
for (node = ...) --> ofnode_for_each_subnode()
fdt_get_name() --> ofnode_get_name()
fdt_getprop() --> dev_read_string()
- nx_display_probe() removed, nx_display_dev_probe_uclass() renamed to
nx_display_probe().
- dts: pinctrl is supported now, therefore s5p4418-pinctrl.dtsi added,
mmc- and i2c-entries extended appropriately. New mmc-property
"mmcboost" added.
- Handling of Configs for LCD backlight control reworked because (among
others) not setting CONFIG_S5P4418_ONEWIRE and/or CONFIG_PWM_NX has
caused errors when compiling board/friendlyarm/nanopi2/onewire.c.
- arch/arm/cpu/armv7/s5p4418/cpu.c: '#include <linux/delay.h>' inserted
because it has been removed from common.h.
- board/friendlyarm/nanopi2/board.c: Several includes inserted because
some includes have been removed from common.h.
- Several initialisations of static variables to 0 removed because of
appropriate errors of patman.
- CONFIG_SYS_RESERVE_MEM_SIZE removed, has not been used anymore
- s5p4418_nanopi2_defconfig: "CONFIG_PINCTRL=y" added because pinctrl
is supported now. "CONFIG_EFI_LOADER=n" removed (there have been
boot errors "efi_runtime_relocate: Unknown relocation type 0" at a
previous U-Boot Version without this). "CONFIG_DM_I2C_GPIO=y" removed
because I2C-peripherial is used (Nexell I2C driver). Some configs
moved down for cosmetic reason.
- Handling of Configs for LCD backlight control reworked because (among
others) not setting CONFIG_S5P4418_ONEWIRE and/or CONFIG_PWM_NX has
caused errors when compiling board/friendlyarm/nanopi2/onewire.c.
- CONFIG_SYS_MEMTEST_START, CONFIG_SYS_MEMTEST_END, CONFIG_CMDLINE_TAG
and CONFIG_CMD_BMP moved from s5p4418_nanopi2.h to
s5p4418_nanopi2_defconfig.
- "#undef CONFIG_CMD_IMLS" removed in s5p4418_nanopi2.h
Changes in v2:
- arch/arm/mach-nexell/serial.c removed because this is for the UARTs
of the S5P6818 SoC which is not supported yet. S5P4418 UARTs are
different, here the (existing) PL011-code is used.
- line '... += spl/' in in arch/arm/mach-nexell/Makefile deleted, this
change has already been stated in the commit message but was missing
nethertheless.
- commit "i2c: mmc: add nexell driver (gpio, i2c, mmc, pwm)" splitted
into separate commits for gpio, i2c, mmc, pwm.
- cosmetic: line "obj-$(CONFIG_NX_GPIO) += nx_gpio.o" in
drivers/gpio/Makefile moved up.
- several Bugfixes in nx_i2c.c.
- the i2c-driver has been for s5p6818 only. Code extended approriately
in order s5p4418 is also working.
- "probe_chip" added to the i2c-driver.
- doc/device-tree-bindings/i2c/nx_i2c.txt added.
- Since drivers/pwm/pwm-nexell.c is an adapted version of
s5p-common/pwm.c an appropriately changed version of s5p-common/pwm.c
is used now. Therefore arch/arm/mach-s5pc1xx/include/mach/pwm.h
copied to arch/arm/mach-nexell/include/mach and s5p-common/Makefile
changed appropriately.
- i2c: "nexell,s5pxx18-i2c"-driver is used now instead of "i2c-gpio".
i2c0 and i2c1 added. I.e. dts files changed appropriately.
- dts: gmac-, ehci- and dwc2otg-entries removed because the appropriate
functionality is not supported yet.
- s5p4418-pinctrl.dtsi removed because there is no pinctrl-driver
available.
- "obj-$(CONFIG_ARCH_NEXELL) += s5p-common/" added to
arch/arm/cpu/armv7/Makefile since s5p-common/pwm.c is used now instead
of drivers/pwm/pwm-nexell.c.
- cosmetic: additional GPL license text removed, SPDX-License-Identifier
is enough. Furthermore file path removed (two files).
- USB related configs removed because USB is not supported yet.
- CONFIG_CMD_MEMTEST moved from s5p4418_nanopi2.h to
s5p4418_nanopi2_defconfig.
- MAINTAINERS: "F: drivers/pwm/pwm-nexell*" deleted because
arch/arm/cpu/armv7/s5p-common/pwm.c is used now. Furthermore double
line "F: drivers/video/nexell/" deleted.
