[PATCH v4 0/8] arm64: Add the support for new Exynos5433 SoC

[Chanwoo Choi]

This patchset adds new 64-bit Exynos5433 Samsung SoC which contains quad
Cortex-A57 and quad Cortex-A53. It is desigend with the 20nm low power process.

This patchset is based on Linux 4.0-rc1.

Depends on:
- This patch-set has the dependency on Exynos5433 clock driver[1][2] and pinctrl driver[3].
The Exynos5433 clock controller patch-set[1][2] was merged by Sylwester Nawrocki
and Exynos5433's pinctrl patch[3] receviced the acked message by Tomasz Figa.

[1] [PATCH v5 00/13] clk: samsung: Add the support for exynos5433 clocks
    - https://lkml.org/lkml/2015/2/2/368
[2] [PATCH v3 0/9] clk: samsung: Add clocks for remaining domains of Exynos5433
    - https://lkml.org/lkml/2015/2/2/784
[3] [PATCH v4] pinctrl: exynos: Add support for Exynos5433
    - https://lkml.org/lkml/2015/2/23/728

Changelog:
Changes from v3:
(https://lkml.org/lkml/2015/2/12/65)
- Rebased it on Linux 4.0-rc1.
- Remove ARM_GIC and ARM_AMBA dependency because CONFIG_ARM64 already included them.

Changes from v2:
(https://lkml.org/lkml/2014/12/2/134)
: Fix the range of GICC memory map (0x1000 -> 0x2000)
: Fix address space of 'range' property under 'soc' node
: Add ADMA / I2S dt node for sound playback/capture
- Select ARM_AMBA/ARM_GIC/HAVE_S3C_RTC for Exynos5433 in arch/arm64/Kconfig
- Send separate patch-set for Exynos5433 clock controller[1][2] and pinctrl[3]

Changes from v1:
(https://lkml.org/lkml/2014/11/27/92)
- Merge two patches (patch2, patch3) to solve incomplete description
- Exynos5433 Clock driver
 : Fix wrong register and code clean by using space instead of tab
 : Add CLK_IGNORE_UNUSED flag to pclk_sysreg_* clock for accessing system control register
 : Remove duplicate definition on the patch for CMU_BUS{0|1|2} domain
- Exynos5433 SoC DTS
 : Remove un-supported properties of arch_timer
 : Remove 'clock-frequency' property from 'cpus' dt node
 : Fix interrupt type from edge rising triggering to level high triggering
   because Cortex-A53/A57 use level triggering.
 : Fix defult address-size/size-celss from 1 to 2 because Exynos5433 is 64-bit SoC
 : Modify 'fin_pll' dt node to remove un-needed and ugly code
 : Move 'chipid' dt node under 'soc'
 : Use lowercase on all case in exynos5433.dtsi
 : Add PSCI dt node for secondary cpu boot
 : Add 'samsung,exynos5433' compatible to MCT dt node
- Divide pinctrl patch from this patchset
- Add new following patches:
  : clocksource: exynos_mct: Add the support for Exynos 64bit SoC
  : arm64: Enable Exynos5433 SoC in the defconfig

[PATCH v4 4/8] arm64: dts: exynos: Add SPI/PDMA dt node for Exynos5433

[Chanwoo Choi]

This patch adds SPI (Serial Peripheral Interface) dt node for Exynos5433 SoC.
SPI transfers serial data by using various peripherals. SPI includes
8-bit/16-bit/32-bit shift registers to transmit and receive data. PDMA is used
for SPI communication.

[PATCH v4 6/8] arm64: dts: exynos: Add RTC and ADC dt node for Exynos5433 SoC

[Chanwoo Choi]

This patch adds RTC (Real Time Clock) dt node for Exynos5433 SoC and adds
ADC dt node for Exynos5433 SoC. The c1b501564c98a94b4(iio: adc: exynos_adc:
Add support for exynos7) commit supports the ADC for Exynos7. Exynos5433's ADC
IP is the same with Exynos7's ADC IP. Exynos5433 has a little different from
ADCv2 on ADC_CON2 register. Exynos5433 don't contain OSEL/ESEL /HIGHF of ADC_CON2.

Can we collapse all these entries into one for EXYNOS? I don't
want to end up with endless lists like we have on arm32 when
there is no platform specific code that is actually controlled
by this anway.

Should we try to come up with a way to better share parts of this with the
exynos5 dtsi files you already have in arm32? I suspect that there is a
significant overlap.

Can you put the aliases into the per-board files? There might be boards that
do not support all the uarts and all the i2c controllers but only want to
provide aliases for a subset of them, without holes in the numbering.

OK, I'm not opposite with you opinion.

But, I have a question.
If we put the aliases into the board dts file instaed of SoC dtsi,
each board dts file may use the different alias name about same phandle.

Currently, 32-bit Exynos5 SoC (which is included in arch/arm/boot/dts)
didn't support the Cortex-A53/A57 and PSCI.

The 32-bit Exynos5 SoC support the Coretex-A7 or A15 and big.LITTLE Exynos5 SoC
use the MCPM (Multi-Cluster PM) driver for secondary cpu on/off instead of PSCI.

Yes, that is the idea. In particular with the uarts, the intention is
that the numbering of the device nodes in /dev is the same that is
printed on the board (if any), which may be different from the numbering
internal to the SoC.

Yes, I understand that. What I meant is sharing the nodes that are identical
between e.g. all exynos54xx by using a common .dtsi file that can be included
by 5420, 5433 and 5440.

I check the uart device with Exynos5433 SoC based on Linux 4.0-rc1
If some board use the serial_0 and serial_3 as following in board dtsi,

	&serial_0 {		--> UART 0 device
		status = "okay";
	};

	&serial_3 {		--> UART 3 device
		status = "okay";
	};

The serial core driver create the follwoing /dev/ttySACx device node
by using the number of alias. It maintain the same device number of internel to the SoC.

	root@localhost:~# ls /dev/ttySAC
	ttySAC1  ttySAC3

I'm not completely following. So you have set the serial1 alias to
the &serial_0 device node and serial3 to &serial_3?

Why not use serial0=&serial_0 and serial1=&serial_3? Does the serial0
alias have a special meaning?

Exynos5433 use the quite different base address of each IP from Exynos5250/5420/5800.
Exynos5433 SoC cannot use the devicetree node in Exynos5 dtsi (arch/arm/boot/dts/exynos5.dtsi).

I add following aliases and serial_1/serial_3 dt node in board dtsi:
I tested that change the alias of serial_x node.
	
	aliases {
		serial0 = &serial_1;
		serial1 = &serial_3;
	};

	/* Add 'linux,stdout-path' property to print kernel log by using ealycon */
	chosen {
		linux,stdout-path = &serial_1;
	};

	[snip]

	/* serial_1 is used for printing kernel log throught JIG cable */
	&serial_1 {
		status = "okay";
	};

	&serial_3 {
		status = "okay";
	};

In result, serial driver create the /dev/ttySAC0 for serial_1 and /dev/ttySAC1 for serial_3.
But, I cannot complete the kernel booting and stop it with following kernel log

After modification, I got the successful kernel booting.

If should use the serial_0 device and then modify the 'aliases' as following:
I have to modify the commandline of bootloader if the commandline of bootloader is used
instad of default kernel command line.

I agree.

I check the some issue for only using the CONFIG_ARCH_EXYNOS
insead of CONFIG_ARCH_EXYNOS7 and CONFIG_ARCH_EXYNOS5433.

Each CONFIG_ARCH_EXYNOS{7|5433} configuraiton was used on following list:
- CONFIG_ARCH_EXYNOS7
arch/arm64/boot/dts/exynos/Makefile:1:dtb-$(CONFIG_ARCH_EXYNOS7) += exynos7-espresso.dtb
drivers/clk/samsung/Makefile:17:obj-$(CONFIG_ARCH_EXYNOS7)	+= clk-exynos7.o
- CONFIG_ARCH_EXYNOS5433
drivers/clk/samsung/Makefile:13:obj-$(CONFIG_ARCH_EXYNOS5433)	+= clk-exynos5433.o

We may can fix it as following by only using 'CONFIG_ARCH_EXYNOS' without any specific configuration.

arch/arm64/boot/dts/exynos/Makefile:1:dtb-$(CONFIG_ARCH_EXYNOS) += exynos7-espresso.dtb
drivers/clk/samsung/Makefile:17:obj-$(CONFIG_ARCH_EXYNOS)	+= clk-exynos7.o clk-exynos5433.o

I think that we need the opinion of Kukjin Kim (Exynos SoC Maintainer)
and Sylwester Nawrocki(Samsung clock Maintainer)

I fix the my wrong expression. Some tty driver use the 'console' bootparam.

What is the "earlycon=exynos4210,0x14C20000" doing here? Should that not just be
"earlycon=exynos" or something like that when you set the correct stdout-path?

If you need the numbers to match, maybe there is still a bug in the serial port
driver and it uses some arbitrary number (e.g. probe order, or ascending
MMIO address) for the console instead of the alias?

"earlycon=exynos4210,0x14C20000" is correct bootparam. You can check
it on Documentation/kernel-parameters.txt as following.

     exynos4210,<addr>
                Use early console provided by serial driver available
                on Samsung SoCs, requires selecting proper type and
                a correct base address of the selected UART port. The
                serial port must already be setup and configured.
                Options are not yet supported.

The serial port driver request the 'tty' device information to print kernel log.
So, bootloader is supposed to pass the 'tty' device as upper example.
But, The bootloader could not get the the 'alias' information in board dtsi.

I need yout opinion about using the CONFIG_ARCH_EXYNOS
instead of CONFIG_ARCH_EXYNOS7/CONFIG_ARCH_EXYNOS5433?

But it's crazy to do this when you have a DT. Please fix the existing
devicetree files that use this to just list 'earlycon'.

The syntax above only makes sense for classic board files that we
do not support for exynos any more.

Following earlycon patch for exynos soc was merged in Linux 4.0-rc1.
- commit-id: b94ba0328d3b36ff95f5074c0e9b44f90dc56bb5 (serial: samsung: Add support for early console)
Almost Exynos SoC use the same UART IP of Exynos4210.

If you mean that "earlycon=exynos4210" naming will be changed to "earlycon=exynos",
we have to modify the drivers/tty/serial/samsung.c.

No, what I mean is that you should use just "earlycon" instead of "earlycon=..."
when you have a DTB. You have the OF_EARLYCON_DECLARE() in the driver as
well, so that should just work.

EARLYCON_DECLARE() is really just a hack that allows users to override the
early console from the command line without modifying the stdout-path
property. Don't put that into a dts file.
